The Greatness of Honeywell Air Purifiers


Honeywell True HEPA Allergen Remover, 465 sq. Ft, HPA300

The Honeywell HPA300 air purifier is among the best air cleaning devices on the market today. Not surprisingly, legions of factories, households, and hospitals across the world use Honeywell air purifiers. These purifiers use True HEPA filters. That means they can help you remove up to 99.97% of pollution from your indoor air.


The HPA300 is Most Suitable for Extra-large Rooms


The product is designed to purify extra-large rooms. But what’s an extra-large room? It’s one that measures roughly 20 X 20 feet. That’s equal to about 465 sq. ft. That makes the HPA300 a great solution for indoor pollution in relatively large living rooms, basements, large bedrooms. The rest of this Honeywell HPA300 manual will discuss everything you should know about the HPA300.


The HPA300 Sucks in Dirty Air via the Front and Pushes it out via the Top


The HPA300 sucks in dirty air from the front. Contaminated air enters the device through a front grille that covers two types of filters. The first filter — the prefilter — eliminates large particles. Some of particles removed include pet hair, pet dander, and lint.

The carbon prefilter also helps you kick out odors and even gaseous contaminants from the air. At least, that’s what Honeywell says. But this Honeywell HPA300 manual needs to insert a brief note right there. It’s that no air purifier effectively eliminates gaseous pollutants. Not even those that use True HEPA filters.

The air then migrates to the True HEPA filters. The device uses 3 Type R True HEPA filters. At this point, fine pollutants such as dust, pollen, and mold spores get sucked out of the air. True HEPA filters eliminate fully 99.97% of contaminants larger than 0.3 microns.

Once the air is clean, the HPA300 forces it out through the top.


How to Set Up the HPA300


Open the box. Get the HPA300 out. The air purifier is black in color. It features a pleasingly solid, stable design. It weighs 24lbs. That’s quite heavy. But then, it’s hard to knock the device over. Still, you’ll want to put it in a place that sees little foot traffic.

I mentioned that the device draws in air via the front side and releases it via the top. But how does that help you? It means you have quite a few options when it comes to where to put your HPA300. You can “hide” it somewhere in a corner. Or, place it against the wall.


Unwrap the Carbon Prefilter and True HEPA Filters


I assume your device is brand new. I mean, I’ve heard of one or two stories where a person says their device seemed a little used.

The prefilter and True HEPA filters come in plastic packaging. So, remove the prefilter and HEPA filters from the packaging.


Remove the Front Grille


Next, remove the front grille. On the top right and left of the grille, you’ll see symbols that look like hands. Press that area gently until the grill releases. Then, pull it out and put it aside. Now, detaching the grille from the device should be pretty easy.


Put the True HEPA Filters into the Housing


The next thing you do is place the 3 HEPA filters into the housing — one after the other.

Note: be sure to leave the tabs facing outward (see below image). That’ll make replacing the True HEPA filter down the road (about 12 months later) easy.

Place the Prefilter In front of the True HEPA Filters


Take the carbon prefilter and place it in front of the outermost True HEPA filter. To secure the prefilter in place, tuck its edges into the tabs around where the HEPA filters sit.

At this point, replace the front grille. But how do you do that?

Hook the tabs on the bottom of the grille into the slots at the bottom of the HPA300. Then, hold the grille at the top and press the area with the “hands” symbol down into the device. At this point in this Honeywell HPA300 manual, you’re about to start using your device.


Plug the HPA300 into an Electrical Outlet


It’s time to connect your HPA300 to electric power. Simply take the power cord (it’s about 6 feet) and plug it into an electrical outlet that’s working right.


The Control Panel


The HPA300 comes with an “easy tap” control panel. Now, take a second and glance at the control panel. You should see the following features:


  1. The dimmer
  2. The Turbo setting
  3. The Allergen, General Clean, and Germ settings
  4. The power icon
  5. 2 electronic filter change reminders
  6. The Auto shutoff timer


How the Control Panel Functions


We’ve seen the control panel carries 6 important features. Now, I want to handhold you through each feature so you can use your HPA300 with confidence.

Let’s roll.


Feature #1: The Power Button


The power icon/button appears somewhere in the middle of the HPA300’s easy-tap control panel.

It does three things for you.

One, the power button turns the device on. Two, the button turns the device off. Three, it enables you to adjust fan speed.

Simply tap the button once, and your HPA300 bursts into life.


Feature #2: 3 Air Cleaning Modes


Now, you want to see whether the fan speed settings are working right. Tap the power icon so you can toggle through 3 important settings: the Germ, General Clean, and Allergen settings.

How do I know I’ve selected the fan speed I want? That’s easy. You’ll see illumination (blue) shooting from an area next to the setting you’ve chosen.


When to Use Each Fan Speed


Pay attention to this section of the Honeywell HPA300 manual. It’s very important that choose the right setting at the right time. That’s how to get the most of your air purifier.


The Allergen Setting


Are you allergic to pollen? If yes, don’t worry. You have the Allergen mode to turn to. When spring comes around, choose the Allergen setting. You’ll sleep much better. And the symptoms will improve.

Here’s something important that this Honeywell HPA300 manual notes. It’s that the Allergen setting coincides with the setting other manufacturers usually call “High.” Maybe Honeywell considers “Allergen” to be a more informative term than just “High.” Makes sense if you ask me.


The Germ Setting


Select this setting when the cold and flu season kicks in. The Germ mode is what other manufacturers typically call “Low.”


The General Clean Setting


The General Clean setting coincides with what most manufacturers call “Medium” setting. This is the setting to choose for your day-to-day air cleaning.


Feature #3: The Turbo Setting


Note: You should only switch to the Turbo setting after choosing any one of the three settings described above.

In other words, you shouldn’t try to run the device on Turbo right after turning it on. To shift to the Turbo mode, simply tap the Turbo button once. And if you tap it again, your device goes back to the setting you had before the Turbo mode.


Feature #4: Electronic Filter Change Reminders


The Honeywell HPA300 air purifier features 2 electronic filter change reminders. Take a peek at the left side of the control panel.

You should see two filter change indicators namely the “Check Filter” and “Check Prefilter.” When it’s time to replace either of the filters, an LED light comes on. You should replace the carbon prefilter every 90 days (3 months).


The True HEPA filters Last about 12 Months


As for the True HEPA filters, you should change the once in every 365 days or 12 months. At least, that’s the manufacturer’s recommendation. But in this Honeywell HPA300 manual, I’ll tell you about my experience.

I bought my wife a Honeywell HPA300 in 2016 as a birthday gift. She’s allergic to pollen and dust. She’s also asthmatic. As if that’s not enough, we live in a city that’s rather dusty throughout summer. Well, we could always move. But we have jobs in this town and a huge mortgage. Plus, we feel a strong sentimental attachment to our home.

The house swarms with pollen when spring comes around. I guess that’s why we replaced the prefilter 5 times for each of the two years we’ve owned the HPA300.

Generally, you’ll change the prefilter more often if the air contains a high concentration of pollutants.



The Filter Change Indicator Light is on. So What Do I Do?


I’ll assume you’ve bought the right replacement filters. You should buy Honeywell Filter R True HEPA Replacement Filter – 1 Pack of 3 filters . As for the prefilter, pick Honeywell Premium Odor-Reducing Air Purifier Replacement Pre-Filter, HRF-APP1 / Filter (A+). You may want to leave this Honeywell HPA300 manual awhile and check out the prices on Amazon. But don’t forget to come back and read the rest of it.

Now, replace the filters. Usually, you won’t replace both filters at the same time. That’s because they don’t have the same amount of filter life.

Once you’ve replaced the prefilter or True HEPA filters, press the indicator in question for at least 2 seconds. Only stop when the light turns off. When that happens, know you’ve just reset the indicator to the default clean status.


Replacing the Filters before the Indicators Turn on


Can I change my filters before the time to do so comes? I anticipated that question. My answer is you can change the prefilter and HEPA filter before they’re due for replacement. Here’s how to do it.

First, replace the filters. Then, turn the HPA300 off. But do not unplug it. Then, press each filter change indicator for at least five seconds. At that point, each indicator light illuminates. After doing that, press the buttons again until the lights go off. When the lights turn off, know that the filter change indicators have been reset.


Feature #5: The Auto Shutoff Timer


With the HPA300, you can decide how long you want the device to run. That’s where the auto shutoff timer comes in.

You can choose any one of these options: 2, 4, or 8 hours. If you choose 2 hours, the device will run for 2 hours and then shut off automatically. Note: only use this feature if you intend to run the device continuously. In this Honeywell HPA300 manual, I’ll describe for you how to use the auto shutoff timer. Using this feature is pretty easy.


How to Use the Auto Shutoff Timer


To use this feature, do the following. Tap the icon for the auto-off timer once. Then, select the timing option you want (2, 4, or 8). To do that, tap the timer icon to toggle through the timing options indicated. Stop only when you hit the option you need. If you want to pick 8 hours, for instance, tap the timer button until you see the illumination shoot to the number 8.


Feature #6: The Dimmer


In this Honeywell HPA300 manual, I’ll tell you about the brightness that emanates from this device’s control panel. Frankly, it’s rather bright.  You’ll most likely want to dim it a bit.

But how do you do that?

The dimmer lets you control the level of illumination from the LED displays easily and fast. There are 3 options to choose. You can select High, Low, or Off. When you turn the device on, it automatically selects High.

To switch to Low, tap the dimmer icon just once. If you’re a light sleeper and don’t want the light, tap the icon two times. Doing that turns the lights off.

But won’t that also turn the device off? No, it won’t.

And if for whatever reason you wish to switch back to maximum brightness, tap the device one more time.


How Often Should I Clean My HPA300?


When it comes to cleaning the HPA300, forget about using water and a cleaning solution. Don’t use water. Also, stay away from chemical solutions and wax polish.

Here’s what you need — a dry, soft piece of cloth. Use that to dust off the device’s external surfaces.

Earlier in this Honeywell HPA300 manual, I mentioned that you shouldn’t wash the filters. I need to remind you of that warning. That’s because I don’t want you to render your filters useless.

Honeywell recommends that you clean your HPA300 4 times each year or once every 3 months. Of course, you can clean it more often if you so prefer.


What if I’m Going Away for Some Time?


If you won’t be around for more than a month, the manufacturer says to do the following. Remove the prefilter and HEPA filters. Then, put them in a plastic bag that won’t let air in and store them away.


Can I Wash the Filters for My HPA300?


I know the question you want to ask at this time. “Can I wash the prefilter and HEPA filters for the HPA300?

No, you can’t.

They’re not washable. And that’s not a good thing. That’s because you’ll continue spending money on filter replacement throughout your ownership of the HPA300.

Luckily, you won’t spend a fortune. Check prices on Amazon.


Honeywell HPA300 Manual: the Final Word


In this Honeywell HPA300 manual, I’ve dealt exhaustively with every important aspect regarding the use of the HPA300.

The air purifier comes with an easy-to-use control panel that lets you get the most of your device. All you need to do is tap. Turning the device on or off is pretty easy — just tap the power button.

Also, the power button lets you toggle through the 3 settings: Germ, General Clean, and Allergen. And the Turbo mode, dimmer, and auto-off timer operate pretty much the same way — just tap.

NEVER use cleaning solutions or water to clean the body of your HPA300. Additionally, NEVER wash the prefilter or True HEPA filters. That’d damage them.  Replace the prefilter every 3 months. Change the True HEPA filters every 12 months. I hope you found this Honeywell HPA300 manual helpful.

5 thoughts on “Honeywell HPA300 Manual”

  1. I have had my Honeywell air purifier for about 2 years. I can’t recall if I purchased the insurance for it, but I probably didn’t. It worked great until 3 months ago when the change filter light came on. I replaced the HEPA filter and the pre-filter. After plugging it back in the change filter light is still on and will not go off, so I am afraid to run it even though it still runs. I’m aware Honeywell doesn’t want me to take it apart, but I am considering it. It was a pricey purchase and I can’t just run out and buy another one right now. So, what can do?

  2. Electrostatic spark from my bathrobe , destroyed the unit , bought a second one A300, got destroyed again once it got a very tiny spark from my socks.

    • Same to me, i just bought one last week, as long as I turn it to high (allergy) or turbo setting within a few seconds it turn off by itself.
