Product Reviews

We’ve searched high and low across the interwebs to bring you the best air purifiers on offer. This includes top features, effectiveness, and 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

This air purifier is made to cover large rooms up to 356 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 five-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 28-decibel option during the night or baby’s naptime.

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

What We Like

Five-Stage Filtering Process

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 covers the rest, trapping any remaining pollutants in a fine mesh section. This includes tiny particles such as dust, pollen, and mold.

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

Smart-Auto Mode Senses Air Quality

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.

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 28 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. You’re covered under warranty if anything goes wrong within the first year.

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.

What We Don't Like

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, or you can install an app to adjust the settings. However, the app is finicky, and even connecting it to Alexa doesn’t give you many options.

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.

High Speed is Loud

While the lowest setting is nice and quiet, the middle and highest settings get louder. If you need to do some intense air purifying, keep in mind you’ll be doing it at the expense of a zen surrounding.

Filters Need Replacing Often

This machine alerts you when the filters require replacing. Many customers get notified about this every 1-2 months, which is a bit excessive.

Product Specs

Dimensions 13.98 inches by 8.11 inches by 20.87 inches
Weight 15.85 pounds
Color options White
Number of filters Four
Extra features Real-time monitoring, child safety features

2. Hathaspace Smart Air Purifier

Best Filters

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

What We Like

Customers Get a 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 eyes 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.

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

Smart Air Purifier With Auto Sensor

We love that this unit gives you air quality feedback. The smart sensor detects the air around you, looking for pollutants. It then adjusts the fan in real-time, going higher if the air quality is poor and staying low if the air quality is okay.

Plus, the unit displays the air quality level, so you know what’s happening in your home environment.

What We Don't Like

Doesn’t Impress In Big Rooms

While the coverage for this is 700 square feet, customers find that it works better in smaller rooms. In larger rooms, they don’t tend to notice a huge difference, even when the air sensor says the air quality is good.

Air Quality Sensor Malfunctions

While we love that this includes an air quality sensor, and don’t get us wrong, it works a lot of the time, some customers are dissatisfied. When the unit turns on, it’s usually red, even if you have good air quality. But within an hour, it turns green, letting you know the air quality is good, even if customers can still smell and see dirty residue. You can’t always trust it.

Product Specs

Dimensions 13 inches by 7 inches by 20 inches
Weight 12 pounds
Color options White
Number of filters Four + ionizer
Extra features Whisper quiet mode, remote control included

3. Pure Enrichment Air Purifier

Best Budget-Friendly Air Purifier

With thousands of reviews, 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. An auto-timer also runs continuously for two, four, or eight hours.

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

What We Like

Overall Simple and User-Friendly 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. If anything goes wrong regarding the machine’s mechanisms, contact them immediately 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 With Customers

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, our minds are put at ease.

Three Stage Air Purification With HEPA

Even though this is a pretty budget-friendly option, we love that it comes with a true HEPA filter. The three-stage air purification process includes a pre-filter with activated carbon, a true HEPA filter, and UV-C light.

This unit captures 99.97 percent of particles in your home. The UV-C light takes care of 99.9 percent of viruses and bacteria, which is great if you’re immuno-compromised or just don’t want to get sick!

What We Don't Like

Only Covers 200 Square Feet

Smaller 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.

High Speed Setting Is Loud

The low and medium-speed settings are nice and quiet, but if you want the cleanest air, you’ll need to opt for the high-speed setting. Unfortunately, it’s quite loud. If you have this in your office, you’ll need to turn it down for work calls.

Hit or Miss With Eliminating Odors

Customers find that this is hit or miss with odors. Some customers say it’s great for odors, but many disagree. It seems to work much better in smaller rooms, but if you have stinky dogs, smoke residue, or even cooking smells you want to eliminate, this unit might not hit the mark.

Product Specs

Dimensions 10.8 inches by 7 inches by 12.5 inches
Weight 6 pounds
Color options White
Number of filters Three + UV-C
Extra features Auto timer

4. Levoit Air Purifier

Best Portable Air Purifier

At five 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 where 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.

What We Like

Best in Size With Good Coverage

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

Some of us need our air purifiers 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?

Three-Stage Filtration System

Three stages of filtration and the same amount of fan speeds offer comparable options to other machines out there. Filters include a pre-filter, true HEPA, and activated carbon one. This can help remove organic compounds, ammonia, and more.

Unique Specs Including 360-Degree Air Intake

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, investing in new electronic equipment can have 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 the entire time you have the purifier at home.

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

What We Don't Like

No Filter Change Indicator

With no filter change indicator, you must 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.

It’s Loud on Every Setting

Even though this comes with a night mode, customers find that every setting is loud in its own way. On night mode, it’s quiet, but it has a high-pitched whining noise. On the highest setting, you’ll need to raise your voice to chat over this air purifier. We don’t recommend this option if you need something more discreet.

Prompts You to Change Filters Often

The filters should last around six months, but the unit might prompt you to change them earlier. Some customers said they got notified after two weeks! This might make sense if your house is pretty dirty, but overall, you’d like the filters to last longer.

Product Specs

Dimensions 7.9 inches by 7.9 inches by 12.9 inches
Weight 5 pounds
Color options White
Number of filters Three
Extra features Pre-filter, 360-degree side air intake, brushless motor

5. Coway Mighty Air Purifier

Best for Saving Energy

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.

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 this unit’s convenience.

What We Like

Sleek and Stylish Appearance

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 various modern and minimalist design schemes.

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

Convenience Factors Make This Unit Stand Out

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 particular room ready.

When changing 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.

4-Stage Filtration System

With four stages, this does a fantastic job of clearing the air. It has a pre-filter, deodorization filter, a True HEPA filter, and a vital ion. Together, these filters capture 99.97 percent of particles as small as 0.3 microns.

What We Don't Like

It’s Huge and Bulky

This isn’t a discreet air purifier. It’s almost two feet tall! At 16.8 by 9.6 by 18.3 inches, you need quite a bit of free space for this unit.

Up to 53 Decibels Loud

While the lowest setting only runs at 24.4 decibels, the highest setting is much noise at 53.8 decibels.

Much Maintenance Required

After a few weeks, you will need to clean the filters and the unit often. It’s not the easiest to clean. Plus, the replacement filters don’t seem as high quality as the original filters.

Causes of Indoor Mold Growth

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

Mold reproduces by traveling through the air, and it thrives on moisture. 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 various sizes and shapes, offering different features. There are a few stand-out specifications to keep in mind while shopping:

Pre-Filter

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

The pre-filter catches the largest of particles and 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 is a top-quality air filter since it can filter both small and large particles (5).

The HEPA filter forces air through a fine piece of mesh, which traps things like dog dander and pollen.

This very dense filter is a common option for many air purifier manufacturers because of its efficiency.

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 roughly every few months. Most manufacturers will indicate when the filter needs to be changed in the manual.

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 works? 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 afterward. This makes for a hands-free purifier that you can trust to work its magic.

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 tackle mold spores and other annoyances, including pet dander, pollen, dust, and more.

Know what you’re looking for before you buy. This includes what types of filters you need and any important convenience factors.

We hope our top five list has been insightful for you, and we wish you luck in your mold war.
