22 Jan Air Purifier vs Dehumidifier vs Air Purifier Dehumidifier Combo
Last Updated on
Air purifier vs dehumidifier: which of these two useful products do you need? Maybe you’d be better off with a 2-in-1 product?
Maybe you also want to know whether you can use an air purifier and a dehumidifier in the same room. Or whether they deliver similar benefits.
I wrote this post to answer these questions and more.
First things first: Is there an air purifier dehumidifier combo that really works?
Air Purifier Dehumidifier Combo Review
Wouldn’t it be great to have one product that performs both roles and does both jobs right?
In truth, such a product already exists. But as far as I know, only one company makes the product are interested in. And that isn’t exactly a good thing.
The only product I’ve seen on Amazon is the Pure & Dry HEPA70 (70 Pint) Dehumidifier and Air Purifier .
You can also find a cheaper version of this device.The cheaper version removes 50 pints of moisture per day. Another difference is that this option comes with a lower purification coverage (1,000 sq. ft. ). Here’s the product:Pure & Dry HEPA50 (50 Pint) Dehumidifier & Air Purifier.
Let’s take a closer look at it.
Pure and Dry HEPA70 (70 Pint): A Brief Review
I’ll jump right in and state the specs.
- Dimensions: (16W X 26H X 10.4D) inches
- Weight: 43 lbs
- True HEPA70: Removes 70 pints of moisture per day
- Integrated True HEPA filter to suck in airborne air pollutants
- 3 options for draining water
- Air purification coverage: 1,400 sq. ft. for large and extra-large room purification
- Works well even in temperatures as low as 41 degrees Fahrenheit
- Adjustable humidity setting: 40% – 70% (allows 5% increments)
- Bucket full indicator light
- Auto-defrost system to prevent build up of ice on coils
- Removable and washable prefilter and HEPA filter
- Sealed digital display
- Color: light gray
- Warranty: 1 year
- Caster Wheels UL Certified
- Energy consumption: 740 watts
- Can withstand temperatures as low as 41 degree Fahrenheit: Great for the basement
- 2-in-one deal
- Great for people with space problems
- Large purification coverage
- Quite heavy
- A power guzzler (740 watts!)
- Percentage of negative reviews almost same as positive reviews percentage
Honestly, I’ve not used this device.
But here’s what I can say about the product. It works.
However, there are quite a few complaints from users. In fact, as many people praised the product as hated it.
In addition, only one company sells the product. That means you won’t have options when it comes to parts replacement. Also, I saw that very few people have bought the product on Amazon. That means it’d be hard to find answers to use-related questions from real users.
Aside from that, the device seems quite pricey. It’s possible to buy a separate air purifier and dehumidifier at a combined cost that’s significantly lower than this device’s price. And if the Pure and Dry HEPA70 (70 Pints) broke down, that’d be two problems showing up at the same time.
Lastly, the combo uses too much energy. The device is more of a dehumidifier than a purifier. And on average, a dehumidifier consumes 2x more energy than an Energy Star certified refrigerator. That’s according to research conducted by the Cadmus Group, Inc.
Editor’s rating: (3 / 5)
Based on my research online and the reviews I’ve seen, the Pure & Dry HEPA70 (70 Pint) Dehumidifier and Air Purifier isn’t a product I’d recommend. I’d say to just buy a separate purifier and a separate dehumidifier. That settles that.
Let’s now address the question that brought you here.
Air Purifier vs Dehumidifier: What Problems Do You Have?
An air purifier performs different functions than a dehumidifier. However, some of the functions overlap. That’s probably why you’re trying to compare these two devices. The next couple sections should help you make an informed decision.
Do You Have Molds?
An air purifier reduces mold spores from your indoor air. But a dehumidifier prevents mold from growing in the first place. If you’re asthmatic or have breathing challenges, you want to breathe in clean air all of the time.
For mold, you probably need both devices. The right purifier will help you address airborne mold spores and other allergens. A dehumidifier, on the other hand, reduce the moisture so mold will start hating your place.
What Works Best for a Damp Basement?
What if your basement stays damp most of the time and mold is a big problem? You probably need a dehumidifier down there. An air purifier helps remove mold spores, too. But it’s not designed to work in such conditions.
Luckily, there’s a product that works as a purifier and as a dehumidifier at the same time. And the good thing is it that the product safely tolerates very low temperatures. Meaning it’d be perfect for that damp basement.
First, scrub the mold away or remove it using any other suitable method. Then, place a dehumidifier in the basement to make sure the place stops being a cozy home for molds.
Face the Seasons without Worries
If it’s wintertime and there’s too much moisture in your home, consider buying a dehumidifier. It’ll help make the place a lot more comfortable.
But your dehumidifier won’t be much use when spring shows up and an army of pollen particles are looking for a new home! For spring, you should be armed with an effective air purifier, preferably a True HEPA air purifier. Such a product is your best bet when it comes to managing nasty allergies and asthma in spring.
What about when summer comes around? If it’s summertime and the air carries dust and loads of other pollutants, keep your air purifier(s) running. It would also be a good idea to have a humidifier. A humidifier moisturizes dry air, making your home cooler and cozy.
Which Works Best for Asthma or Allergies?
Dust mites and mold spores are common allergy triggers. You don’t want them in your home if you suffer from allergies or asthma. But what device do you need if you want to manage your allergies?
An air purifier or a dehumidifier? An air purifier can remove dust mites, mold spores and lots of other particles from your indoor air. That means this device can help you manage your allergies and asthma. But a dehumidifier also prevents mold and dust mites from thriving. That means that the device, too, can help you manage allergies and asthma.
But consider this: a dehumidifier won’t remove pollen or smoke particles from the air. What does that mean? A dehumidifier may not be as effective as an air purifier when it comes to managing allergies and asthma. If allergens rather than too much moisture are your biggest worry, buy an air purifier.
Can I Run an Air Purifier and a Dehumidifier in the Same Room?
Yes, you can. Each machine will start doing what it does best. Your air purifier will work hard to help you get rid of mold spores, dust, dust mites, pollen and other contaminants.
Your dehumidifier, on the other hand, will work hard to regulate your indoor humidity. It would seem that using the two devices simultaneously would deliver greater benefits than using either alone.
“Air purifier vs dehumidifier” is the first post on Dustfreerooms.com that has mentioned dehumidifiers. You may want to read dehumidifier reviews on Amazon before buying.
As for air purifiers, the best product for you depends on the particular problem you need help with. Again, you should read honest air purifier reviews before making your buying decision.
We’ve discussed the various benefits of air purifiers elsewhere on this website.
Let’s jump right in and learn how a dehumidifier functions.
How Does a Dehumidifier Work?
A dehumidifier works the same way a refrigerator does. That is, the principle is technically the same. The process starts when a dehumidifier sucks in indoor air that carries excess moisture.
The moisture-filled air then passes over a cooling coil. Most of the damp air condenses into water droplets. And the water droplets collect in a drainage tank near the base of the machine.
The rest of the air passes over a re-heating coil which warms it before it gets released back into your home. That’s basically how a dehumidifier works.
You may wonder: how will I know when my dehumidifier’s tank is full?
Most dehumidifiers have a mechanism that alerts you when the tank gets full so you can empty it.

9 Dehumidifier Benefits You Should Know
There are many reasons people buy dehumidifiers. You need to understand these benefits and decide whether you too want to enjoy them. Here are the benefits:
1. Regulation of Your Home’s Humidity Levels
Dehumidifiers reduce moisture levels in your home. That ensures that mold, mildew, and dust mites don’t thrive in your home.
And that’s a HUGE benefit if you suffer from asthma or allergies.
2. Your Laundry will Dry Faster
Using a dehumidifier has your laundry drying faster. That translates into lower electric bills and of course, savings.
3. Your Food Won’t Spoil Fast
With a dehumidifier, food items don’t spoil as fast as they would in its absence. That helps you avoid food wastage, saving you money. That said, no one ever buys a dehumidifier to keep their food fresh! In other words, having a dehumidifier won’t eliminate your need for a fridge.
4. Slows Down Corrosion
Using a dehumidifier prevents or slows down corrosion. That means your laptop and other electronics will not depreciate as fast as they would in damper conditions.
5. Mold and Mildew Control
You’ll see less mold and mildew in your walls, on the floor, clothing, furniture, draperies and many other places. If you’re not buying new clothes or curtains all the time, you can save lots of money over time.
6. May Help You Address Mold Odors
A dehumidifier prevents mold growth in your home. And molds gives your indoor air a certain unpleasant smell. Less mold means less mold odors which also means a more livable indoor environment.
7. Prevents Structural Degradation of Your Home
Too much humidity can cause deterioration in your home. It may cause wood to warp or crack.
In addition, too much moisture encourages mold growth in your walls. Also, excess moisture may cause metal fittings to rust.
In short, too much moisture in your home can end up destroying its structural integrity. A dehumidifier removes excess moisture, making sure you’re not always spending money on home repairs.
8. A More Comfortable Indoor Environment
A dehumidifier can help your home feel a lot more comfortable than it actually is. The device reduces humidity in your home, helping you feel more comfortable without needing to run your air con. That means lower electric bills in the long run and growing savings.
9. Air Quality Improvement
Too much humidity in your home tends to lower the quality of your indoor air. Most people don’t see using a dehumidifier as a strategy to improve indoor air quality. But improving indoor air quality can be tough if there’s too much moisture. Since a dehumidifier removes excess moisture, it can help improve indoor air quality.
Air Purifier vs Dehumidifier: Which Device Should You Buy?
Just like an air purifier, a dehumidifier reduces dust levels in your home. It also helps improve indoor air quality. Additionally, a dehumidifier ensures that mold, mildew, and dust mites don’t make your home their home. Running a dehumidifier does help improve a room’s air quality. Which means it can help people manage allergies and asthma.
However, an air purifier trumps a dehumidifier when it comes to eliminating allergens.
Verdict: If allergens and air pollutants are your biggest concern and you can’t buy both products, pick a purifier. But if excess moisture is what gives you problems and you have no breathing issues, buy a dehumidifier. You can also buy the air purifier dehumidifier combo. You can either choose the Pure & Dry HEPA50 (50 Pint) Dehumidifier & Air Purifier – 2-in-1 Combo or Pure & Dry HEPA70 (70 Pint) Dehumidifier and Air Purifier – Sealed Hepa Filter . However, the 2-in-1 product isn’t something I feel particularly enthusiastic about.
You can use a dehumidifier and air purifier in the same room simultaneously. So, nothing prevents you from owning both of them if your budget allows that.
