Save on Top Brands at SylvaneHow do you clean the air in your home? This is an important question for allergy and asthma sufferers or anyone with respiratory issues. Dust, pollen, smoke, and odors can irritate your airways. Room air purifiers are an easy way to take care of the problem.

They work silently in the background, only reminding you of their presence when they need a filter change. Their filters clean nearly 100% of allergens like mold spores, pollen, and pet dander from the air. Some purifiers can remove toxic gases and kill germs, too. Let’s take a closer look at how to select the right air purifier for your needs.

The best all-around air purifier for rooms up to 500sq.ft. in size

Coway AP-1512HH Mighty Air Purifier with True HEPA Filtration

Coway AP-1512HH Mighty Air Purifier

Coway AP-1512HH Mighty Air Purifier

The Coway AP-1512HH Mighty Air Purifier is very quiet as it cleans your home’s air. It features a True HEPA filter that captures allergens down to 0.3microns in size. It removes odors, smoke, pollen, and dust, plus it uses ION Technology* to kill bacteria and viruses. The pre-filter is washable so it saves you money on filter changes, especially if you have pets.

On top of the purifier you can see a visual representation of air quality. Blue light means clean air, purple means polluted air, and red means highly polluted air. You can set it to run in Auto mode so that it selects one of the 3 fan speeds itself, according to need.

The Mighty Air Purifier is powerful enough to perform 4 complete room air changes per hour in a space measuring up to 500 square feet. In other words, it moves up to 268 cubic feet of air per minute on high. You can place it in a child’s bedroom, a living room, or a home office. While its CADR (Clean Air Delivery Rate) scores aren’t as high as the Honeywell or the IQAir, it’s plenty powerful for small and medium-size rooms.

The filter replacement light tells you when it’s time to put in a new one. Each HEPA filter lasts for up to 1 year. The carbon odor filter lasts up to 6 months. Their replacement costs are currently very reasonable compared to systems like the IQAir below.

If you only want the system to run for a short amount of time, you can set a timer so it shuts down unattended. On high it consumes 77.8 watts like a bright room light, or on low it uses just 4.9 watts. You can use ECO-Mode where the purifier will shut down after 30 minutes of not detecting pollution. Of course, it’s Energy-Star Qualified for efficiency.

More features of the Coway AP-1512HH Mighty Air Purifier:

  • Comes with a limited 3-year warranty
  • Low speed fan operates at 24.4dB, quiet as a whisper. High speed reaches only 53.8dB.
  • Has the British Allergy Foundation Seal of Approval
  • On California’s Certified Air Cleaning Devices list for emitting no, or very low, amounts of ozone—read more about this below*


Quiet and efficient for small rooms up to 360 sq.ft.

Winix PlasmaWave 5500-2 True HEPA Air Purifier

Winix PlasmaWave 5500-2 True HEPA Air Purifier

Winix PlasmaWave 5500-2 True HEPA Air Purifier

The Winix PlasmaWave 5500-2 air purifier also begins by cleaning air through a washable pre-filter. The pre-filter catches pet hair and dust. Then the air passes through a carbon filter to remove odors from chemicals and tobacco smoke.

The next stage is a True HEPA filter that filters out 99.97% of pollutants down to 0.3microns in size. That cleans the majority of allergens out of the air.

The final stage on the Winix 5500-2 is their PlasmaWave Technology. Without generating any ozone, PlasmaWave releases charged ions that bond with particles of water vapor in the air. The charged molecules, or Hydroxyls, neutralize germs like bacteria and viruses as well as chemical vapors and gases. If you don’t want to use the PlasmaWave stage, you can turn it off on the digital control panel.

You don’t have to use the touch control panel to manage all the functions of the Winix 5500-2. It comes with a remote control that lets you turn it off and on, choose one of the 4 fan speeds, and enable the Auto mode to let it work independently.

Auto mode depends on the device’s sensors that detect air quality in the room. You can view the current state by checking the color of the LED. Red means dirty air, amber shows that air quality is fair, and green is good.

Besides user-controlled fan speed and automatic mode, you can turn on Sleep Mode. This operates the fan at the lowest, quietest setting and dims the Air Quality LED.

One LED light that you’ll want to notice is the filter change indicator. While the HEPA filter lasts up to a year, the carbon filter needs to be cleaned every three months. But it can also last up to a year with regular cleanings.

Not only does the 5500-2 save you money on filter replacements, it’s Energy Star certified. While it can easily perform up to 4 room air changes per hour in a 360-square-foot space, it consumes less energy on the highest fan setting than the Coway AP-1512HH. It’s also very quiet, especially on the lowest setting.

More features of the Winix PlasmaWave 5500-2:

  • Covered by a 2-year limited warranty
  • Rated by AHAM as excellent for clean air delivery
  • Has a timer that runs for 1,4, or 8 hours


Top of the line air purification technology with the best filtering system for all allergies including MCS

IQAir HealthPro Plus Air Purifier

IQAir HealthPro Plus Air Purifier

IQAir HealthPro Plus Air Purifier

IQAir’s HealthPro Plusis the most powerful air purifier in our guide. Its efficient designhas won several awards over the past decade from places like Consumer Digest, Wired Magazine, and Although the initial cost seems steep, the filters inside last two to four times as long as those in other purifiers. That saves you money and effort over the long term.

The IQAir HealthPro Plus uses a specially-mounted silent fan to draw in room air as quickly as possible. It is shock-mounted and placed between noise-absorbing filters so that the IQAir makes no virtually sound when running on its lowest setting. You can run it day and night and not realize it’s operating.

The first air cleaning phase is a Pre-Max Pre-Filter that catches pollen, dander, and mold spores. It will last up to 18 months before you need to replace it.

The second step is a V5-Cell gas phase filter with granulated activated carbon that absorbs toxic vapors like formaldehyde from new construction and irritating odors from smoking and cooking. It’s made to last up to 2 years before needing a replacement.

The third phase is the HyperHEPA filter that catches ultrafine particles like bacteria, viruses, and tobacco smoke particles. Better than HEPA that catches 0.3micron-sized pollutants, the HyperHEPA removes microscopic particles as tiny as 0.003 microns, ten times smaller. It’s designed to keep working for up to 4 years! Even though it can remove more particles, it’s lifetime is four times longer than most regular HEPA filters.

When the cleaned air emerges from the HealthPro Plus, it comes out soft and smooth. IQAir designed this system to output in a nearly-full circle of 320-degrees without causing drafts.

The filters and fan are housed in a Swiss-made casing built from high-impact resistant ABS plastic. Each IQAir is fully tested once it’s completely assembled. Each one comes with a certificate of performance. Plus, IQAir offers a 10-year warranty on the HealthPro Plus. That’s much longer than the typical one or two-year warranties offered by other companies.

As for the details of how to control and maintain the HealthPro Plus, it’s made to be easy to manage in every way. The control panel shows you the remaining lifetime of each filter. When it’s time to replace them, they are very simple to pull out so you can insert the new ones.

The control panel lets you program a timer and choose one of 6 fan speeds. You can use the remote control for the same functions. It doesn’t have an air quality light, but since it works so silently and so well, this isn’t important. You should have clean air as long as the HealthPro Plus is operating.

More features of the IQAir HealthPro Plus:

  • Rolling casters on the bottom make it easy to move from place to place
  • Manufacturer specifications say it can filter a room up to 1125 square feet
  • For 4 room air changes per hour, it’s recommended for a room up to 563 square feet
  • Minimum noise 25dB, maximum 69dB
  • Minimum wattage 27W, maximum 215W

Rabbit Air MinusA2 Air Purifier (SPA-700A)

Rabbit Air MinusA2 Air Purifier (SPA-700A)

Rabbit Air MinusA2 Air Purifier (SPA-700A)

The Rabbit Air MinusA2 is small enough to mount on a wall or rest on a tabletop. In fact, it rather resembles a Wi-Fi router. But inside the slim exterior, it’s packed with advanced filtration technology.

There are six stages to the MinusA2 purifier. One of those stages is user-customizable. This means you can select one of the following filters: odor remover, VOC toxin absorber, pet allergy filter, or germ defense.

The other five parts of the filtration system are the washable pre-filter for dust and pet hair, the medium filter for mold spores and pollen, the activated carbon filter for odors, the BioGS HEPA filter for allergens down to 0.3microns in size, and the negative ion generator. Although the ion generator can make your air smell fresher, you can turn off this feature.

While it’s operating, the MinusA2’s sensors continually monitor the level of pollution in the room’s air so it can automatically adjust to a higher or lower fan speed. It has 5 speeds total that can be selected from its control panel or the remote control. On the lowest setting, the MinusA2 makes just 25.6dB of noise. That’s barely audible.

The control panel will alert you to when it’s time to change a filter. It can also indicate the air quality. Plus, you can turn on a mood light or nightlight if you desire. Or in Sleep Mode, the LED lights are dimmed and the purifier runs on the quietest setting. Better yet, the MinusA2 will automatically save power for you by switching the Sleep Mode on its own if the room is completely dark.

More features of the Rabbit Air MinusA2:

  • Covered by a 5-year warranty on parts and labor
  • Has a carrying handle
  • Energy-Star certified


Economical choice for rooms under 500 square feet in size 

Honeywell HPA300 True HEPA Whole Room Allergen Remover Air Purifier

Honeywell HPA300 True HEPA Whole Room Allergen Remover Air Purifier

Honeywell HPA300 True HEPA Whole Room Allergen Remover Air Purifier

The Honeywell HPA300 filters out allergens, smoke, gases, and odors with a 4-filter system. The carbon and True medical-grade HEPA filters last up to a year before they need to be replaced. You can buy a multi-filter pack at a discount here.

While the Honeywell HPA300 isn’t as silent as some of the other purifiers described above, some owners have stated it provides a pleasant white noise for sleeping. It doesn’t have all the features like a remote and mood lighting, but it’s Energy-Star certified and has strong CADR ratings. Each CADR (Clean Air Delivery Rate) is at least 300, showing that the Honeywell purifier quickly cleans room air.

The controls on the top of the HPA300 let you set a timer for 2, 4, or 8 hours, check the status of the filters, and change the fan speeds. It doesn’t come with a remote control.

More features of the Honeywell HPA300:

  • No wheels or casters, weighs 17 pounds, built-in handles on sides
  • Covered by a 5-year warranty


All these air purifiers are capable of removing allergens like mold spores, pollen, pet dander, dust, and smoke.

If you want air purification in your home, but have a tight budget, consider getting the Honeywell HPA300. It has good CADR ratings and cleans air well even in large rooms.It’s not the strongest at removing odors.

If you want a nearly-silent air purifier, take a look at the Rabbit Air Minus A2, IQAir’s HealthPro Plus, and Coway’s AP-1512HH. All three emit very soft levels of sound on their lower fan settings.

If removing germs are a concern for you, the IQAir HealthPro Plus, the Coway AP-1512HH, the Winix PlasmaWave 5500-2, and the Rabbit Air Minus A2 all kill bacteria and viruses.

If you would like to customize your filter choices, take a look at the Rabbit Air Minus A2. You can dim its lights or use them as mood lighting.

If you want a purifier for multiple chemical sensitivities, you may like the IQAir’s HealthPro Plus. It’s a top of the line system with long-lasting filters.


How to choose the best air purifier

When you’re selecting a room air purifier, you’re not just purchasing an appliance. You’re also committing to a long-term relationship of replacing filters and paying for electricity. It’s important to choose a purifier that works well, but also won’t eat up your budget over the long term. In this guide we’ll review the top five air purifiers and explain what makes them the best for the money. We’ve selected the top ones to protect both allergy and asthma sufferers.

What kind of filtration do you need?

  • Simple filters that remove odors and dust
  • Allergy-relief filters like HEPA that work against pet dander, pollen, and mold spores
  • Smoke removal filters for tobacco and fireplace smoke
  • Chemical vapor removers that remove formaldehyde
  • MCS, filters for multiple chemical sensitivities
  • Germ sterilizer filters

How large is the room where you want to use an air purifier?

Allergy and asthma sufferers can benefit most if the purifier can do 4 room air changes per hour. Measure the length and the width of the room and multiply them to get the square footage. Check that against the manufacturer recommendations. It’s better to have a purifier that is more powerful than you need simply because you can run it on a lower power setting for less noise and less energy consumption.


How much maintenance will the purifier need? How much will replacement filters cost?

Will the air purifier alert you to do filter changes? How long do the filters last? If you can afford the purifier, but aren’t sure about being able to buy replacement filters in the future, consider a different model.

What other features matter to you?

If you’re moving the purifier a lot, is it small and light? Does it have wheels or a handle? If you want to leave it in one room, can you mount it on a wall or place it out of the way?

Here is acautionabout ozone produced by some air purifiers and how it could negatively impact your health.


*Ozone, and why it matters

There was a time when ionizing air purifiers were all the rage. Unfortunately, most models emitted too much ozone. Ozone irritates lungs and isn’t safe to breathe. The state of California tests air purifiers for electrical safety and ozone emissions. They won’t pass a purifier that puts out more ozone than 0.050 parts per million.
