Best Air Purifiers for Mold of 2020

Just the tool you need in your war against mold.

Do you find black spots on the bathroom tiles or white bits in the kitchen cabinets? Maybe you have an inkling that the air ducts were invaded. To say that mold is unattractive would be an understatement.

Not only does it look gross, but when mold travels through the air, it can cause health problems including but not limited to respiratory conditions.

Even the best air purifiers for mold won’t wipe it out from whatever surface it’s lurking on. However, they can remove spores in the air, odors and can help you breathe better. We’ve included the best options in our guide.

Causes of Indoor Mold Growth

To treat mold and the contaminated air around, it’s essential to understand how it gets there.

Not all fungi are bad, but mold, in particular, spreads quickly. It’s often found in the great outdoors but can make its way inside as well, coming from vents, windows and more (1).

Mold reproduces by traveling through the air and it thrives on moisture/wetness. If you live in a particularly humid or wet environment, you’re more susceptible to it.

Imagine all the damp places in your home. We’re talking about crawl spaces, bathrooms, kitchens, basements and laundry rooms, to name a few. When these locations aren’t kept clean and dry, the chance of mold growth increases.

Other ways to prevent mold growth include:

  • Keep your laundry, bathrooms and shower areas well-ventilated.
  • Don’t procrastinate on leaking roofs, windows, and pipes.
  • Be highly cautious when cleaning after flooding.

How Does Mold Affect Your Health?

Some are more sensitive to mold than others. If you already have allergies, you could be a victim of mold growth (2). A few symptoms are:

  • Irritated throat.
  • Eye discomfort.
  • Runny nose.
  • Coughing or wheezing.
  • Skin irritation.
  • Shortness of breath.

For Those with Already Existing Lung Conditions

These symptoms could be magnified by the presence of mold. So if you suspect mold growth in your home, take care and eradicate the source as quickly as possible.

What Are the Benefits of an Air Purifier?

An air purifier won’t reverse already present mold growth, but it will lessen the chance of future growth. It may also help your symptoms subside. Plus, odors will be removed along with airborne mold spores (3). Other benefits include:

  • Removes triggers for asthma and other respiratory conditions.
  • Eliminates other allergens, including dust, pollen and dust mites.
  • Traps smoke which can lead to ear infections or worse (4).
  • Helps decrease outside fumes and environmental toxins.

How to Pick the Best Purifier for Mold

Air purifiers come in a wide variety of sizes and shapes, offering different features. There are a few stand-out specifications to keep in mind while shopping:


A pre-filter is exactly how it sounds. Instead of the primary filter being the only defense, the allergens first move through this phase.

This means that the pre-filter catches the largest of particles and it also helps prolong the life of the second filter in line.

HEPA Filter

You’ll come across this often when shopping for an air filter. HEPA stands for “high-efficiency particulate air” and means it’s a top quality air filter. It’s considered as such because it can filter both small and large particles (5).

The HEPA filter works by forcing air through a fine piece of mesh which then traps things like dog dander and pollen.

This very dense filter is a common option for many air purifier manufacturers because of how efficient it is.

Filter Change Indicator

The majority of filters on the market today won’t last a lifetime. They’ll need to be changed on a regular basis whether this is once every few months or year. Most manufacturers will indicate in the manual when the filter needs to be changed.

However, some machines take it a step further and offer an indicator on the machine itself. This way, you’re notified when it’s time to put in a new filter, which takes away the guessing game or you forgetting over time.

Air Quality Sensor

Wouldn’t it be nice to know how well the air purifier is working? A sensor indicates how clean the indoor air is by monitoring it consistently.

The purifier will kick into a higher gear when the air needs extra attention and then lower to its original level afterwards. This makes for a hands-free purifier that you can trust to work its magic.

The Best Air Purifiers for Mold of 2020

We’ve searched high and low across the interwebs to bring you the best air purifiers on offer. This includes customer feedback which helps us determine which devices are worth mentioning. Of course, we’ve also included any existing drawbacks. Here are the top five:

1. Renpho Air Purifier for Home

Best Quality

RENPHO Air Purifier for Home Bedroom Allergies and Pets Hair, True H13 HEPA Filter Air Purifier for Large Room 301 SQ.FT, Filters Pollen, Smoke, Dust, Pet Dander, Eliminates Germs, Mold, Odors, Ozone Free
Check Price

This air purifier is made to cover large rooms up to 301 square feet. The manufacturer claims it traps and eliminates up to 99.97 percent of airborne pollutants as small as 0.3 microns. This includes smoke, odor, pet dander, pollen and mold.

These allergens will be met by a four-stage filtering process, including a pre-filter, charcoal filter, activated carbon filter and lastly, a HEPA filter.

The smart-auto mode adjusts the fan speed as the purifier scans the air for particles. A sleep mode offers a quiet 35-decibel option during the night or baby’s naptime.

A handy filter replacement indicator will notify you when it’s time for a change.

Why We Love It

Four-Stage Filtering

The pre-filter will remove the largest of particles including dander and hair. A charcoal filter is also in place, specifically for volatile compounds and gases, while the activated one further enhances that process. This includes cooking and pet odors.

Lastly, the HEPA filter takes care of the rest, trapping any remaining pollutants in a fine mesh section. This includes tiny particles such as dust, pollen, and mold.

These four filters combine to take care of anything and everything that could be floating in the air around you.

Smart-Auto Mode

We appreciate that this machine has a mind of its own.

As it scans the air, it’ll automatically switch between “good”, “fair” or “bad” notifications. The color will also change depending on the level from blue to yellow or red, respectively.

The machine will then change speeds based on these qualities, maintaining proper circulation and filtration. This indicates that the machine works with both precision and efficiency.

Child-Friendly Features

With a quiet mode of 35 decibels, the purifier shouldn’t bother you or your little ones at night.

Secondly, a child-safety mode ensures the machine won’t change course if your child tries to push any buttons or change the setting.

Quality Customer Service

A professional customer service support team can make a big difference. This is especially so when something goes wrong or you simply have a question.

Thankfully, Renpho covers you with a 100 percent satisfaction guarantee. Should anything go wrong within the first year, you’re covered under warranty.

For any questions beyond that, they pledge “lifetime support.” This means they’re available to answer any inquiries or help you troubleshoot issues that arise.

Keep In Mind

No Remote Control

Many high-quality air purifiers come with a remote control. For obvious reasons, this can be useful when convenience is a top priority.

This machine, however, doesn’t have this option. It only means that when you want to change the setting, you must do it by hand. Given it’s made to purify one room at a time, we don’t see it as such a big deal, though some may disagree.

2. Hathaspace Smart Air Purifier

Best for Filters

Hathaspace Smart True HEPA Air Purifier for Home, 5-in-1 Large Room Air Cleaner for Allergies, Pets, Asthma, Smokers – Filters 99.97% of Allergens, Dust, Pet Hair, Pollen, Smoke, Odors - HSP001
Check Price

With a five-in-one air purification system, the Hathaspace machine means business. Filters include a nano-cold catalyst filter and cellular-activated carbon filter. There’s also an antibacterial filter, a HEPA filter, and lastly, an ionizer.

Say “goodbye” to mold spores, pet dander and more. The auto mode continuously scans the air and adjusts speed accordingly.

Difficulty sleeping with light and sound? The quiet mode not only brings the noise down a notch but the bright indication lights also switch off.

It’s suitable for up to 350 square feet, which is a fair amount of space to cover.

Why We Love It

Better Sleep

Few things annoy us more than bright lights, loud noises and yucky air when we’re trying to sleep. This machine takes care of all those things.

When in “whisper-quiet” mode (18 decibels), the lights power off to save your eyelids from popping open. And, the noise stays at a minimum. With consistent monitoring of the air around you, deep sleep shouldn’t be an issue.

Five-In-One Purification System

The nano-cold catalyst filter is the first one up to bat, handling large particles, toxic chemicals and mold. Next is the cellular-activated charcoal filter for absorbing smoke, odors and gases.

Then we have the antibacterial option that we love because it handles viruses, bacteria and fungi, all of which seem to multiply come wintertime. After this, the HEPA filter handles 99.97 percent of any remaining particles.

The ionizer on the backside of the machine releases negatively-charged ions. These work to remove and neutralize any odors left in the air.

Remote Control Included

It’s a special add-on that can be convenient. You’ll be grateful for this if you’re busy doing other things or working at home from across the room. Forget getting up to adjust the speed.

The remote control offers you the flexibility you need when time is of the essence (or you’re just feeling lazy — that’s okay).

Keep In Mind

Are Your Allergies Terrible?

At least one customer said they were hoping this machine would tackle their allergens. HEPA filters are known for this, after all. However, the customer was left unsatisfied with the results.

It could’ve been a one-off thing, but for allergy sufferers, it’s best to play it safe. Keep your receipt and payment details nearby in case you want to return it.

3. Pure Enrichment Air Purifier

Most Popular Choice

Pure Enrichment PureZone 3-in-1 Air Purifier - True HEPA Filter & UV-C Sanitizer Cleans Air, Helps Alleviate Allergies, Removes Pet Hair, Smoke & More - For Home, Office & Bedroom
Check Price

With reviews well into the thousands (nearing 3000), you know this machine is popular for a reason. It’s a budget-friendly option and smaller in size than the rest. Its size makes it suitable to tote around and place at your discretion.

An intuitive control panel allows you to easily select your mode of choice. There’s also an auto timer which runs at two, four or eight hours continuously.

The three-in-one filter technology, combined with a UV-C light, destroys pesky microorganisms and captures both large and small particles. A carbon filter and HEPA filter are both included here.

Why We Love It

Overall Design

We appreciate the overall design of this machine. From the intuitive control panel to the straightforward filtration process, it’s a simple option that still offers quality. With four easy-to-use buttons, anyone can figure it out.

When it comes to looks, it won’t stand out or be a nuisance to your room’s aesthetic. Still, it’s worth noting that the only color option is white.

Five-Year Warranty

A five-year warranty guarantees coverage of any malfunction, much longer than many other companies on the market. Should anything go wrong regarding the mechanisms of the machine itself, contact them right away to solve it.

Maybe you just don’t like the machine? Send it back for a full refund. The customer service team operates seven days a week, so they shouldn’t be difficult to reach.

It’s Popular

That may seem like a silly reason to believe in something but hear us out. Word of mouth means a great deal these days.

Many boast about its effectiveness and how simple it’s to operate. Furthermore, customers also appreciate the design and overall appearance. With all this backup cred to go on, our minds are put at ease.

Keep In Mind

Only Covers 200 Square Feet

Smaller in size than many, this machine will function best in a cozy room or office space, up to 200 square feet. Otherwise, you might be disappointed with the lack of efficiency in larger spaces.

Additional Specs

Dimensions10.8 inches by 7 inches by 12.5 inches
Weight6 pounds

4. Levoit Air Purifier

Best in Portability

LEVOIT Air Purifiers for Home Allergies and Pets Hair, H13 True HEPA Air Purifier Filter, Quiet Filtration System in Bedroom, Removes Smoke Odor Dust Mold, Night Light & Timer, Vista 200
Check Price

At 5 pounds, this little guy wins the portability award. The dimensions come in at 7.9 inches by 7.9 inches by 12.9 inches, making it the best option for transport and moving between locations.

It’s the only one on our list thus far that comes in a cylindrical shape. This may allow you to fit it into areas that larger, boxy machines are a no-go. The 360-degree air intake also ensures it can be placed virtually anywhere in the room and still work as it should.

The company also claims this machine saves on energy if that’s important to you. It reportedly uses less than 30 percent of the energy of other air purifiers.

Three stages of filtration and the same amount of fan speeds offer comparable options to other machines out there. Filters include a pre-filter, HEPA and activated carbon one.

Why We Love It

Best in Size

Yes, it will only cover a small area because of this — 161 square feet to be exact. However, it weighs just 5 pounds and is easy to carry around!

Some of us need our air purifier on the go whether it’s nap time, working hours or any other situation. Even better, its shape makes it easy to toss into a carry-on bag or backpack. Need we say more?

Unique Specs

This machine offers a few specifications that stand out in our books. The first being its 360-degree side air intake. It ensures you have options where placement is concerned. Plus, it promises better ventilation than devices with a one-sided intake.

The second unique feature worth mentioning is the advanced brushless motor. Without brushes that wear down with time, you should be able to prolong the machine’s lifespan, saving costs in the long run. This may help prevent the air purifier from overheating too.

Two-Year Warranty and Lifetime Support

As you’re probably aware by now, investing in new electronic equipment can come with pitfalls. These difficulties can range from a faulty machine to poor customer service.

Thankfully, you have a two-year warranty on this machine, should any issues arise during that period. The lifetime support option indicates that a customer service team will be ready to support you for the entire time you have the purifier at home.

It’s good to know you have someone to call when something goes funny.

Keep In Mind

No Filter Change Indicator

Are you the type of person that forgets things easily?

With no filter change indicator, it’s on you to stay up-to-date on when the filters need changing. While the company recommends this occurs every six months, depending on your air quality, it may need to be sooner.

Consult your user manual to ensure you don’t miss any important directions.

5. Coway Mighty Air Purifier

Best for Saving Energy

Check Price

For those concerned with their energy consumption, we have an air purifier for you. After 30 minutes of undetected air troubles, the machine automatically switches to eco mode. It will still be on, but the fan won’t be running.

It comes in a sleek design and black color, standing out among mostly white options. As a result, it could blend into darker rooms with ease.

Accommodating areas up to 361 square feet, it covers quite a bit of ground.

Like many other purifiers, three fan speeds are automatically selected based on the rate of pollutants in the area. The auto timer and filter change indicator add to the convenience of this unit.

Why We Love It

Sleek and Stylish

Many may not care about the looks so much, but for others, it’s a crucial consideration. The box is thin and presents an understated aura. Its black color will fit in a variety of modern and minimalist design schemes.

A circular structure on the front side resembles a speaker and overall, the aesthetics are pleasing.

Convenience Factors

Between the auto timer, filter indicator and auto-switching between modes, we couldn’t ask for much more convenience in a machine.

The timer can be set to one, four or eight hours, depending on your schedule and when you need a certain room ready.

When it comes time to change the filter, you won’t need to determine what’s up as the indicator does it for you. Following that, there’s no guessing the state of the air quality. The machine handles this too and switches modes when need be.

Washable Pre-Filter

Many filters aren’t washable and we’re glad this one is. For those with many bodies in the house and especially pets, listen up.

The pre-filter catches hair, dust and other large particles lurking about. So, the fact that you can clean it and not have to change it automatically is a big bonus.

Mold Be Gone

From the air, at least! We can’t guarantee that the best air purifiers for mold will cut it out at its original location. However, the machines can make a big difference where air quality is concerned.

Generally speaking, giving the air a good sweep will not only tackle mold spores, but other annoyances including pet dander, pollen, dust and more.
