DYSON PURE COOL TP04 REVIEW

 

Editor’s rating: 4 out of 5 stars (4 / 5)

 

The Dyson Pure Cool TP04 is a 3-in-1 deal that’s worth a look. First, it’s an air quality sensor. It quantifies the air pollution in the room and calculates a detailed air quality report for you.

Second, the TP04 is a portable room air purifier. If the air quality is bad, the machine automatically roars into action and starts sanitizing the air. 

Third, the thing is a fan. The air purifier-fan combo pushes out a soft breeze of clean air that cools you as you listen to some soothing music. To accomplish that, it leverages Dyson’s famous Air Multiplier Technology.

One more thing. The Dyson TP04 is Amazon enabled. You can actually talk to it. It’s also Wi-Fi and Bluetooth enabled, a smart choice.  And it looks cute. You won’t ever want to “hide it.” It subtly tells visitors that you value the coolest things in life.

With the TP04, the allergy season ceases to be such a terrifying prospect. And the tobacco or marijuana smoke that wafts from your neighbor’s apartment bothers you much less. 

But is this air purifier a good buy? Read this Dyson Pure Cool TP04 Review and find out.

Is the Dyson TP04 the Best Air Purifier?

Dyson Pure Cool, TP04 – HEPA Air Purifier and Tower Fan, White/Silver

 

I don’t know.

How could anyone ever measure that, seriously?

Well, lots of people have conducted numerous tests to measure the potency of air purifiers. But in the end, you mainly want to hear what real users of a product think about it.

But I can confidently say this: my TP04 wasn’t money poured down the drain.

My Dyson  sits in my son’s rather small bedroom (13 X 12 feet). And if he doesn’t sleep like a log every night, it’s not because the air purifier is producing too much noise.

Since we bought this Dyson, spring has ceased to be such a dreadful prospect.


Dyson Pure Cool TP04: A 3-in-1 Deal

 

The Dyson TP04 combines three appliances into one superior quality product. The item is a fan, an air cleaner, and an air quality sensor at the same time. How cool is that?

The product keeps your room cool during summer because it’s a fan. During winter, you can choose to enjoy only the air purification benefits. Or you can reverse the airflow and use both functions together.

Setting Up the Dyson TP04

 

Setting my Dyson up was super easy. The device’s filter comprises two main parts. Further, each part contains two key components.

The first component is an outer HEPA filter designed to suck in relatively large particulate matter. On the inner side of this filter is an activated carbon filter. Dyson says that the carbon filter has the ability to filter out much smaller particles. And that includes molecules from odors and fumes.

I simply took the device out of the box and assembled it within minutes. It was a matter of clicking into place the two main parts around my fan’s base.

Then, I snapped the covers on the filters. The pieces fit perfectly. Finally, I sat the product on the floor of my bedroom, plugged it in, and fired it up. It’s that easy and fast.


But Does Dyson Pure TP04 Really Work?  

 

The straightforward answer is that it does.

I have evidence that the Dyson I bought wasn’t money flushed down the drain.

First, I have real-time graphs and other data on my Dyson Link app that proclaim the product’s potency. Second, I have what I’ll call “anecdotal evidence.”

I mean, I have consistently slept better ever since I bought my Dyson. I’m not asthmatic, though. But I’m still seeing great benefits.

And I’m not the only one.

My son keeps telling me how much he loves his Dyson.

He’s 14 as of this writing. And he’s a lovely little boy. Sadly, he’s asthmatic.

Before I bought a Dyson for my son as a birthday gift mid-2018, his life was awful. He’d sneeze and wheeze so bad especially around springtime. Of course, he took meds. But they weren’t doing much good for him.  

At some point, his symptoms deteriorated so bad I thought we’d lose him. I honestly can’t say his Dyson air purifier saved him. But it sure did help.


My Son’s Asthma Symptoms Have Improved

 

Frankly, I’ve not evaluated this device’s efficacy using scientific methods. But judging from what I’ve seen and the reports I’m getting, I’d say the Dyson Pure Cool TP04 air purifier works.

Well, my son still has to endure his seasonal allergies. However, his symptoms no longer subdue him.

My boy may not care much about the numbers displayed on his device’s LCD screen. All that matters to him is that breathing has stopped being such an unpleasant experience.

Thanks to the Dyson TP04, my son breathes easier and sleeps much better.

 

Asthma and Allergy Certified

 

All Dyson air purifiers have been tested and proven capable of helping asthma and allergy sufferers. 

The Asthma and Allergy Foundation of America agrees that this device, and all Dyson purifiers, are great for improving asthma and allergy symptoms. 


Unboxing the Dyson TP04 Air Purifier

 

The Dyson TP04 air purifier features a slender, tall design. Do you agree that tall, slender people look stunning?

I didn’t know this was true of fans as well until I saw my Dyson. It’s easy on the eye. And it greatly enhances the overall look of your room pretty much like your lampshade does.

The Dyson TP04 is the kind of device visitors notice quickly upon entering your home. It says to all, “The person who owns me loves the finer things in life.”


Features and Benefits

 

Let’s consider each of the features I mentioned above one by one and see where that leaves us.

Weight: 10.98 Pounds — Light and Portable

While some parts may seem metallic, this device is pure plastic. At just 10.98 pounds, the unit is quite light.

As a result, the Dyson Pure Cool is pretty easy to move around. Due to its light weight and its rather tall design, knocking it over is easy. The product looks pretty delicate and flimsy. Better be careful as you walk around the house. The Dyson TP04 isn’t exactly cheap, remember.

But while the Dyson Pure Cool looks sort of like flimsy, it’s quite tough. Dyson’s engineers have subjected this device to quite a few rough tests.

And that includes dropping the product from different heights.

So, stop worrying about tipping your device over and damaging it. But you don’t want the air purifier to fall on your child. 


Dyson Pure Cool’s HEPA Filter

 

The unit comes with a 360-degrees glass HEPA filter. This True HEPA filter should remove (and does) 99.97% of particulate matter smaller larger than 0.3 microns. 

With this option, you’ll stop worrying about most PM10 and PM2.5 particles. You will stop fretting about contamination from household dust, pollen, mold spores, and pet dander.

PM10 are course particles whose diameter ranges from 2.5 microns to 10 microns. Luckily, human lungs are able to deal with most PM10 particles. Your Dyson should easily handle the rest of these particles.


Dyson Pure Cool’s Activated Carbon Filter

 

But you still have PM2.5 to worry about. PM2.5 particles are fine particles with a diameter that’s smaller than 2.5 microns. These particles can enter the bloodstream and cause serious health issues. In fact, PM2.5 are way more dangerous than PM10 particles because they’re tinier. 

Some of the possible health conditions include heart attacks, heart disease, asthma, decreased lung efficiency, lung irritation, difficulty breathing.

It gets worse.

Research reveals that PM2.5  may cause premature death. Did you know air pollution kills 7,000,000+ humans each year? Blame PM2.5 for this terrifying state of affairs. 

The Dyson TP04 removes these harmful PM2.5  particles from indoor air. Well, it may not remove everything, but it does a great job.  The fan’s activated carbon filter  (and ACFs in general) is designed to handle PM2.5 particles.

These microscopic particles include household odors, VOCs (Volatile Organic Compounds), and various gaseous particles.

Dyson air purifiers are way better than many I’ve reviewed when it comes to removing smoke, NO2, VOCs, and other PM2.5 particles.  Many Dyson users from places with frequent wildfires keep touting this device for its highly effective smoke removal ability.

I also believe that the TP04 is among the best air purifiers for exhaust fumes ever made. Exhaust fumes contain tons of NO2 and other oxides. These fumes also contain benzene and other VOCs.

And this Dyson is great at handling such contaminants. If you live by a freeway, stop worrying. Instead, buy the TP04. Or grab any of these air purifiers for exhaust fumes


Airflow Reversal

 

This purifier-fan normally releases air through the front. That’s ok as long as it’s not wintertime.

One awesome feature about the Dyson TP04 is that it enables you to reverse airflow. Simply set the device to the backward air flow mode. The feature enables the device to clean your air without cooling you. Instead of cool air flowing out through the front, it leaves the device through the back.

That makes this product a great option for wintertime air purification.


Dyson TP04: Air Sensors

 

This Dyson comes with a set of air quality sensors. These sensors are remarkably accurate. Under the section “LCD Display,” we’ll discuss the various air pollution events these sensors help monitor.

When I crank up my Dyson, the sensors immediately kick into gear. They record air quality numbers throughout the time the device is running.

I’ve noted that when I open the door at night to go check on my son, PM 2.5 and PM10 particles shoot up. I’ve also noted that moving the lawn causes a movement in the air quality numbers. That shows just how sensitive the sensors really are.

Upon consulting the Dyson Link app, I can see what my machine has been doing. I can access detailed information about how VOCs and particulate matter levels in my room changed throughout the duration. 

Maybe Dyson should consider IFTTT integration as that would make the device a lot more useful.

 

The Dyson Pure Cool TP04 Works Well with Alexa

 

The Dyson TP04 works efficiently with Amazon’s Alexa. This capability enables you to speak to your device. And that makes it easier and more convenient to use the device. The purifier-fan is also Wi-Fi and Bluetooth enabled. 

I’m yet to start using this technology (Amazon Alexa), though. I tried making it work but couldn’t. I guess that’s because I’m terrible when it comes to all things tech.

But from what I’ve gleaned while researching, you can use your mouth to do lots of stuff with Alexa. Want to adjust fan speed? Talk to your device. Want to switch to night mode? Simply tell it to do that.

You can also command your Dyson TP04  to turn itself on or off. Heck, you can even ask this technology to tell you about your room’s temperature or air quality. More on this later. 

 

Alexa Limitations with the Dyson TP04

 

However, this Alexa capability does have its limitations.

For example, you can’t control your fan’s oscillation using Alexa. Nor can you tell your air purifier to reverse the way air flows from your device. Maybe Dyson’s engineers will address the issue at some point.

 

Update

 

Actually, you can command your TP04 to oscillate. It’s just that it may not always work the first time you try it. It works.

I also think Alexa should learn to understand more natural language. Wouldn’t be nice to be able to say to it “Alexa, turn fan speed to 5?” Currently, you can’t do that.

Instead, you have to use this phrase, “Alexa, tell Dyson to turn X.” Now, that sounds a little awkward. And it can be cumbersome. 

Also, I’d love for Dyson to build into Alexa a routine that’d combine several common commands. It’d be nice if they had a routine for the following 4  commands: 

 

  1. Alexa, tell Dyson to oscillate
  2. Alexa, tell Dyson to switch to night mode
  3. Alexa, tell Dyson to turn on fan
  4. Alexa, tell Dyson to turn fan speed to 6

 

Alexa would offer a lot more convenience if it could provide a routine for these commands. Having to repeat them each night isn’t fun. 


Dyson Pure Cool’s Oscillation

 

This purifier-fan oscillates. It rotates through a wide range of oscillation angles. The fan comes with a button that helps you choose one of 4 oscillation angles. You can pick any of these four angles: 45°, 90°, 180°, and 350°.

Oscillation allows you to choose which area of your room to direct clean air. As the fan rotates, it mixes and circulates clean indoor air around the entire space.

 

Automatic Shutoff: Get Uninterrupted Sleep

 

My Dyson Pure Cool air purifier also features an auto shutoff. This capability enables you to plan when your fan should automatically turn off. I set my device to shut off after 6 hours every night.

The auto shutoff timer is a pretty cool feature.

I’m able to sleep without needing to wake up to turn off my machine.


10 Fan Speed Settings for Efficient Air Purification

 

How noisy or quiet is the Dyson TP04? I’ve never needed to go beyond setting 5. At this setting, the fan produces no more than 45 decibels. But the noise levels rose up to about 56 decibels on fan speed 10. Some people say that’s high. 

Evidently, the air purifier is one of the quietest devices on the market today. And that makes it great for both home and office use.

Compare this air purifier to the Honeywell HPA300 air purifier which sits in my living room. A HPA300 running on the turbo mode (highest speed) can be quite loud.


Dyson’s Air Multiplier Technology Delivers Efficiency and Safety

 

Dyson’s Air Multiplier Technology enables our Dyson TP04 to circulate clean air across my son’s bedroom. The fan doesn’t use the usual fast-spinning blades that regular fans use.

Still, the fan manages to propel a powerful stream of unobstructed air across the room. Thanks to this technology, every corner of the room receives clean air (fast).

The device is safe to use for people with kids or pets. That’s because the fan is bladeless.

 

Intelligent Air Purification

 

Looking for a smart air purifier? Look no further than Dyson Pure Cool air purifier. Dyson Pure Cool automatically senses air pollution events.

When I set up the Dyson, I could immediately see how dirty my indoor air was. I ran the TP04 for about 50 minutes at a speed of 5.

Findings?

The air quality in my son’s bedroom (13 X 12 inches) improved from fair to good. The product senses a room’s level of pollution and kicks into gear to “normalize” the situation.


Dyson Pure Cool’s LCD Display

 

The device comes with a small, simple LCD display located near the base. It generates real-time reports and graphs so you can learn what’s happening to your air quality.

The display uses different but easy-to-understand icons to represent various air quality parameters. I get no less than 6 air quality reports. Some people might say that’s too much information. And it is.

At a glance, I can see my son’s bedroom’s AQI (Air Quality Index). This measure indicates the room’s current air quality.

Another icon (a flower) shows the level of PM10 in the room. We’re talking pollen, dust, pet dander here— pollutants smaller than 10 microns and larger than 2.5 microns.

There’s also another icon (looks like the usual search icon) that reports on the room’s amount of PM2.5.

A different icon (a car) shows how much nitrogen dioxide there’s in the room. Candles, tobacco smoke, gas stoves and many other sources release NO2.

There’s yet another icon (a conical flask) that indicates VOCs levels. I recently performed a simple test to see what would happen to this parameter.

I sprayed some insecticide into my son’s bedroom. As you might expect, the VOCs spiked appreciably. That’s because the insecticide I used contained lots of particulate matter.

Fortunately, the Dyson Pure Cool TP04 brought the air quality back to pre-testing levels within 2 minutes. I’d say that’s super effective. This feature can help you decide whether you should swap to less harmful products.

The last icon is a double-layered filter. The feature helps you know when to replace either the activated carbon filter or the HEPA filter.

At night, the display dims so you can sleep peacefully. That makes this air purifier a great buy for light sleepers.


The Dyson TP04’s Link App

 

The Dyson TP04 is Wi-Fi enabled.

Thanks to Dyson’s Link app, I can access real-time air pollution reports for my son’s bedroom. Aside from that, the app allows remote control of the fan using my smartphone. Sure, data and messaging cost money. But you and I know it’s nothing the average consumer can’t afford.

The Dyson Link app would be particularly useful for someone with mobility issues. I like it that one can control the device from bed.

Note: Your smartphone or tablet needs to be Wi-Fi enabled. Additionally, your phone should have at least iOS version 10 or Android 5 to connect seamlessly.

Maybe some people see connection issues with their TP04 because their phone isn’t using a compatible operating system.

More on the Dyson App later. 

 

Purification Coverage

 

Dyson’s engineers have subjected the Dyson TP04 t0 countless tests to understand its effectiveness in air purification. They’ve concluded that the device works best for rooms not larger than 290 sq. ft. That’s about 17 X 17 sq. ft, which is a relatively large room.

Of course, you can use the device to clean smaller rooms. But if your room is quite small, it’s best to get a small room air purifier.

The Honeywell HPA100 True HEPA Allergen Remover 155 sq. ft.   is a great option for a medium-sized room. And it’s quite affordable.  However, it lacks quite a few great features that the Dyson TP04 offers. 


Dyson Pure Cool’s Remote Controls

 

The Dyson Pure Cool air purifier features a small, sleek remote. I don’t use the remote. And I don’t worry about losing it.

That’s because the remote sits balanced atop the fan through magnetic force. You’ll most likely prefer to use the Dyson Link app. But there’s no harm in having this feature.


Enjoy a 2-year Warranty with Dyson Pure Cool Air Purifier

 

Dyson offers a 2-year warranty on labor and parts. Unfortunately, the warranty doesn’t include the filter.

Quite a few users have complained about this, but the company doesn’t seem to be in a hurry to address the issue.

Dyson and the rest of the world’s air purifier manufacturers make the largest chunk of their money from selling filters. So it’s easy to see why Dyson might continue dragging its heels on this concern.

 

Complaints from Owners of the Dyson TP04

 

The Dyson isn’t a Great Fan, But it Purifies Efficiently

 

As I researched for this Dyson Pure Cool TP04 review, I came across quite a few dissatisfied owners. The most common complaint was the device’s fan wasn’t any better than an ordinary fan.

In fact, one person felt that the purifier was nothing more than an overpriced fan!

As someone who shelled out hundreds of dollars for this device, I didn’t know what to feel about that claim. I’d bought the Dyson TP04 to use it as a high-quality purifier, and I must say it delivers. But I’ll have to agree that the manufacturer should do something about the fan side’s effectiveness. 

 

Device Lacks CADR Numbers

 

Unfortunately, Dyson doesn’t avail CADR numbers. These numbers make it somewhat easy to compare different air purifiers.  It’d be nice if they started providing CADR numbers like other manufacturers do. After all, consumers are often looking for air purifiers with a high CADR. 

I can’t figure out why Dyson doesn’t submit its purifiers for CADR testing. Could it be that the device would show a significantly lower CADR than cheaper, comparable products? Who knows.

But there’s no doubt that the TP04 works.

 Note: Dyson have provided a detailed explanation about why they don’t CADR-rate their air purifiers. And honestly, what their engineers say makes sense. But that won’t stop people needing to see CADR values. 

 

Dyson TP04 ACH

 

For some reason, Dyson doesn’t indicate the ACH for this and other purifiers.

ACH is a measure of how many times a purifier circulates air in a room within one hour. A device with an ACH of 5 circulates indoor air at least 5 times every hour. 

I’d sure love to see future Dyson portable room cleaners that show this number. 

 

Price is Steep

 

Honestly, I feel the price I paid for our Dyson TP04 was a little too high. 

 

Software Glitches

 

I ‘ve also come across owners of this  Dyson who say they’ve seen a few software glitches . Sometimes, they say the software takes forever to connect. 

That can be quite annoying. But the issue doesn’t affect the device’s overall performance.

Also, the app keeps reminding the user it needs a firmware update. Yet, Dyson keeps saying  they’ve already done so. The app works satisfactorily, though. 

 

How to Connect Your Dyson TP04 (Any Dyson Fan) to the Dyson Link App

 

Step 1

 

Download the Dyson App.

 

Step 2

 

Select “Dyson Products” and choose “Purifier.”

 

Step 3

 

Press the power button near the base of the machine until the Wi-Fi starts blinking.

 

Step 4

 

Got to settings and connect to Dyson

 

Ste 5

 

At this point, you must enter a password. Grab the instructions manual and find the black sticker that has the password. Next, enter the password.

 

Step 6

 

Make sure you’re connected to your Dyson purifier and press “Join.”

 

Step 7

 

Go back to the app and press “Continue.” Next, name your machine. Finally, press “ready to use” and you’re done!

 

The app should start indicating the current air quality situation in your room. There are 4 air quality indicators namely Good (Green), Fair (Yellowish), Poor (Orange), Very Poor (Red).

 

How Do I Connect Additional Dyson Purifiers to the Dyson Link App?

 

Yes, you can link more than one Dyson air purifiers to the app. And it’s easy. Here’s what to do:

 

Step 1: Press and hold the On/Standby for about 5 seconds.

 

Step 2: Look at the Wi-Fi icon. Is it flashing green? If yes, your device is ready to connect. From here, proceed as you did when connecting the first device.

Note: your Wi-Fi should be turned on before you attempt this process.

 

How to Turn off Dyson Link’s Notifications

 

Don’t want to keep getting the Link app’s notifications? Well, turn them off.  It’s easy, and here’s how to do it.

 

Step 1

 

Open the app and tap on “Settings.”

 

Step 2

 

Currently, the notifications button is on. So, slide the button to “Off” position. You won’t see any more notifications from that point.

 

How to Enable and Disable Wi-Fi on Your TP04

 

To enable or disable the Wi-Fi, press and hold the device’s On/Off button for roughly 10-20 seconds.

Also, you can perform this action from the Dyson Link App. Nothing complicated.

But how do you know whether the Wi-Fi feature is enabled or disabled? When it’s active, the Wi-Fi symbol shows a solid white appearance.

 

How to Connect Your Dyson TP04 to Amazon Alexa

 

I assume you live in a smart home. And you’re already using the Echo (2nd Generation) – Smart speaker with Alexa. Don’t have it? You can buy it now on Amazon. It’s affordable. 

With this device, you can do a lot. You can, for example, voice-control your music. You can stream hits from Amazon music, SiriusXM, Spotify, and even Apple Music.

You can even ask Amazon’s Alexa to answer questions. Or check the weather, set alarms, or play music.

Best of all, you can use this innovative technology to control a slew of Alexa-compatible smart home devices. And that includes the Dyson TP04.

The Echo offers over 10,000 skills. These skills enable people to enjoy an unprecedented level of convenience. To get the most of these skills, ask Alexa for help. Simply say, “Alexa, help me get started with skills.”

The Echo comes with 7 microphones that enable it to listen to various voice commands. It can hear you when you speak to it from across your bedroom or other room.

The beauty of using the Echo is that it’s produced by Amazon. That means it gets new features, updates, and device compatibility before third-party Alexa devices do.

Now, let’s jump in and learn how to integrate your Dyson TP04 with Amazon Alexa.

Did I say you need to have a Dyson account first? Yes, go ahead and open one if you haven’t already.

 

Step 1

 

Download the Amazon Alexa app. You can download the Amazon Alexa app from Google Play, App Store, or Amazon App Store.

So, what operating systems is the Amazon Alexa app compatible with? The app is compatible with iOS 11.0 or higher, desktop browsers, and Android 5.1 or higher. It’s also compatible with Fire OS 5.3.3 or higher.

 

Step 2

 

Open the Alexa app and download Dyson Skill. Next, click on “Enable.”

 

Step 3

 

Step 2 should take you to the Dyson Link app. Once the Dyson app loads, it’ll prompt you to log in.

At this point, enter your Dyson account details. Doing this enables Amazon Alexa and links it with your Dyson TP04 or any other Dyson air purifier. That’s all — you’re done.

 

How to Resolve Dyson TP04 Amazon Alexa Issues

 

I’ve read a few Amazon reviews where owners reported that their TP04’s Alexa feature just stopped working. An exclamation mark (!) started showing on the display after they commanded Alexa to perform a task. And the exclamation mark just wouldn’t go away.

The reviewer tried turning their device on, but that was of no avail. The thing started oscillating, but it stopped after about 5 seconds. Regardless of the fan speed chosen, the device wasn’t blowing the air at all.

Fortunately, Dyson replaced the problematic, and the customer was happy.  But for some reason, they didn’t explain the issue.

So, did the new unit work well with Alexa? It did — at first — but it later stopped. That’s when user re-linked their device, and it started working again with Alexa. But their relief lasted only a day. The freaking exclamation mark returned.

Well, that’s sure frustrating. I mean, this Dyson doesn’t come cheap. You’d expect it work seamlessly.

The customer didn’t want to return the device a second time. So, they had to find a way to make it work.

Here’s what they did. First, they delinked the app. Then, they disabled Dyson skill within the Alexa App. Next, they disconnected the device from power.

After waiting for about 20 seconds, they rebooted the router. Finally, they powered up the fan. And it worked!

But this glitch wasn’t a nice thing. If you don’t want to delink and re-link the Alexa app every once in a while, don’t use the feature. Or buy something else.

Luckily, you can use the app or remote control and operate your device without issues.

 

Is Dyson TP04 IFTTT Enabled?

 

No, it’s not. I contacted Dyson on the issue. And they confirmed that none of their Dyson air purifiers is IFTTT enabled.

I know of competing air purifiers in the same price range that offer this capability. Wouldn’t it be great if a decrease in your room’s humidity levels would automatically turn on your humidifier?

But I don’t see this as a bummer. I mean, you can use Alexa to create much convenience in your home. That this purifier doesn’t support IFTTT connection wasn’t a dealbreaker for me.

 

Dyson TP04 Noise Problems

 

Some users have complained of hearing a whining or whistling noise. If that’s you, don’t worry. Simply unplug your machine and leave it for 10 seconds. Then restart it. It should be fine. This sound normally happens when you’re running this purifier on high.

I’ve also noted that my Dyson TP04 sometimes produces some clicking noise. If this happens, don’t worry. This clicking noise isn’t an indicator that something is wrong with your purifier.

The device is designed to make this sound whenever its motor is adjusting air flow direction. As the TP04 switches from front air flow to rear air flow, you’ll hear a clicking noise.

That clicking noise may also be heard during oscillations. If it’s a problem for you, check the area around the base of the purifier for any obstructions or debris.

Interestingly, the TP04 also produces a humming noise even when it’s powered off. So, why does that happen? This Dyson is designed to continue monitoring the air quality, humidity, and temperature even when turned off. Its air quality sensors use small fans that keep the air flowing the whole time. However, the noise isn’t disturbing at all.

But why does the Dyson TP04’s fan speed remain high even when the display has turned green? When the display shows green, it means your air quality is good. And ideally, the thing should switch to a lower speed (if it’s on auto). But it may not always switch to a lower fan speed.

You’ll notice that the machine behaves this way only when it’s on auto mode. This also happens if your room’s window leaks and pollutants keep entering.

But who really needs continuous air quality monitoring when they’re not using their Dyson TP04? No one, that’s who.

And here’s good news. You can actually stop the machine’s continuous monitoring when it’s not in use. To do that, use your app or remote control to switch back to the manual mode. On the remote control, press “Auto” for 5 seconds. The humming noise should stop.

 

Here’s Another Simple Thing you Should Do

 

Go to your Dyson Link app and instruct your machine to stop collecting air quality data when turned off.

 

Here’s precisely how to do that:

 

Step 1: Open the app and go to settings.

 

Step 2: Find the continuous monitoring option and tap to open it.

 

Step 3: Disable “Collect data when in standby.” That icon will immediately turn grey.

 

Step 4: Press “Done” at the top right area of the screen to save the change you’ve made.

The humming noise should stop permanently. And your TP04 will stop consuming energy when it’s not cleaning your room.

 

Dyson Pure Cool TP04 Air Purifier: Final Thoughts

 

The Dyson Pure Cool TP04 is a great purifier. It does make my son’s bedroom a happier, healthier place. But I’m not saying it should be everyone’s choice. I’m only saying I have no regrets. If I were to buy a brand new air purifier today, it’d still want a Dyson. The TP04 works, and it really helps with allergies and asthma. 

I noticed a difference within hours of introducing the machine into my son’s bedroom. It air quality sensor is a feature I really love. And Dyson’s Link app makes the device very easy to use. Also, being able to command your TP04 and tell it what to do is awesome. 

However, the price feels steep. Sure, the device delivers real benefits to users. However, if I had to save money for months or even borrow to buy this fan, I’d probably consider a cheaper alternative. But if money isn’t an issue for you, the Dyson TP04 would doubtless be a great option. Still, I’d love to see a much lower price. 

Overall, I’d say the Dyson TP04 is a great product that deserves a chance from quality-conscious consumers. That’s why I’ve given this air purifier a rating of 4/5 : 4 out of 5 stars (4 / 5)
