Top 10 Best HEPA Air Purifiers For Home Use – 2019 update

HEPA filters are considered the highest efficiency at the current. However, each specific type of HEPA filter is designed to handle a certain number of needs, like allergies, asthma, pet hairs, and dander, or mold.

And in this article, I’m going to review 10 best HEPA air purifiers based on different categories. Keep reading!

  • Coway AP-1512HH – Best overall
  • RENPHO Air Purifier – Top rated
  • LEVOIT Air Purifier – Budget-friendly
  • LEVOIT LV-PUR131S – Best for allergies & asthma
  • Hathaspace Air Purifier – Best for pet hairs
  • Alen BreatheSmart FLEX Air Purifier – Best for dust & mold

Coway AP-1512HH – Best overall

Coway AP-1512HH
Pros
  • Have an additional vital ionizer to clean the air better
  • Can run automatically or be customized through the 3-setting timer, which is flexible
  • The Eco Mode helps to save lots of power and money
  • Sensitive sensor to detect quickly odors or cooking smells

Cons
  • The vital ionizer emits little ozone
  • Can’t shut off the top light

The Coway AP-1512HH operates through a 4-stage filtration system – same progressive technology to other $350 – $450 air purifiers (like the Rabbit Air BioGS 2.0 or the Winix WAC9500) while it’s just under $250.

In this advanced system, out of the washable pre-filter, activated carbon filter, and high-efficient composite True HEPA filter, there is one additional vital ionizer.

It helps to capture the tiniest particles in the air and send them back to other filters, which I found very helpful for asthma or allergy sufferers.

Coway Mighty pollution sensor is the smartest thing that I’ve tried. It automatically kicks on when “smelling” any strange odors or cooking smells while turning off if detecting no pollution within 30 minutes.

Unlike the Honeywell, this runs much more silently. Depending on the fan speeds, it’s within 24.4 dB to 53.8 dB, which is acceptable.

Product Specs

Efficiency99.97% of particles 0.3 microns
Room coverage361 sq. ft.
Noise level24.4 dB to 53.8 dB.
Highlight Features4 Stage Filtration System, Coway Mighty pollution sensor, Filter replacement indicator, noise level ranging from 24.4 dB to 53.8 dB

Equipped with the Eco Mode, 4-stage filtration system, and smart technologies, Coway AP-1512HH is the best-overall air purifier on the market that you can find at under $250.

RENPHO Air Purifier – Top rated

RENPHO Air Purifier
Pros
  • Emit no ozone
  • Have child lock mode to be 100% safe for curious pets or kids
  • Can replace a single filter to save more money

Cons
  • Don’t have a digital screen or Bluetooth, so, the price seems a bit costly

For an air purifier that emits or produces no ozone, RENPHO Air Purifier is the best bet. It’s been certificated by California Air Resources Board (CARB) for no harmful ozone nor UV-C.

The unit utilizes a 4-stage filtration system but a bit different from the previous Coway, it includes one washable pre-filter, one charcoal filter, one activated carbon filter, and finally, one True HEPA filter.

Combining with a good CADR rating of 135 CFM, it is ideal for odor removal within 301 square feet.

What I love the most in this unit is the separated filter replacement indicator that features separate lights for each filter. When any of them starts to flash, it’s time to replace it.

The best thing about this feature is you don’t have to switch the whole filtration system, which saves more money.

Product Specs

Efficiency99.97% airborne pollutants 0.3 microns
Room coverage 301 sq. ft.
Noise level35 dB
Highlight Features4 Stage Filtration System, Smart Auto Mode, the noise level at 35dB, Separated Filter Replacement Indicator

For bedrooms or kids’ rooms, the RENPHO Air Purifier with no harmful ozone emitted is the ideal choice.

LEVOIT Air Purifier – Budget-friendly

LEVOIT Air Purifier
Pros
  • Strong airflow to cover a large treatment space despite its small silhouette -> High efficiency
  • Can turn off the lights to not disturb your sleep
  • Have a touch screen for multiple functions

Cons
  • No remorse. I’m definitely satisfied

Strong airflow (of 230+m3/h), low noise level (24 dB) and lights can be turned off at night, they make LEVOIT Air Purifier the perfect option for bedrooms.

To get such decent performance, there have been many practical technologies applied in the unit. Such as QuietKEAP Technology, Vortexair Technology, and Core 300.

The air purifier has also been certificated for not emitting ozone or using UV/Ion light. It’s satisfied many international standards, like CA PROP 65 certified, FCC certified, ETL listed, Energy Star Verified, and AHAM Verified.

Regardless, the price is astounding – only a mere $100.

While providing a plethora of practical, smart functions, the LEVOIT Air Purifier highlights its incredibly cheap price, making it the budget-friendliest option.

LEVOIT LV-PUR131S – Best for allergies & asthma

LEVOIT LV-PUR131S
Pros
  • Can be compatible with different voice-monitoring foundations to control it
  • Connectable with a smartphone via a special app to use the unit from distances
  • Can calculate the real filter’s life -> save more money

Cons
  • Can’t remove odor or smells
  • Just have one-stage filtration, making the HEPA filter less durable

The LEVOIT LV-PUR131S is the smartest air purifier that I’ve tried.

The unit is built with voice control that users can power it on without lifting their fingers. It’s compatible with different foundations, such as IFTTT, Google Assistant, and Alexa to ensure you’ll feel the most natural to control your air purifier by speaking.

Besides, it’s connectable with a smartphone via the VeSync app so that you can set a timer, schedule or other functions while being away from home.

The biggest selling point is its ability to calculate the real filters’ life and show it via the VeSync app, letting you know about their situation and when to replace them.

This smart feature puts a leap of technology than other “smart” air purifiers – not solidly schedule to remind you after 6 or 18 months’ use.

Hathaspace Air Purifier
Pros
  • The 5-layer purifier can remove pet’s hair/dander and odors
  • Have two large openings to capture more hair
  • The quietest air purifier in the market

It includes a nano-cold catalyst filter, a cellular activated carbon filter, an antibacterial filter, a true HEPA filter, and an ionizer. It takes both functions of an odor eliminator and air cleaner.

The best thing is it not only collects dust mites but also their waste and eggs.

  • Made by NASA airflow engineers to ensure quality
  • Can purify a 700-ft2 space every 30 minutes with whisper noise

Cons

Alen BreatheSmart FLEX Air Purifier is a bang-for-the-buck unit that anyone who readily pays for quality should invest in. The reason is, the unit is developed by NASA airflow engineers with an emphasis on the BreatheSmart FLEX.

If this is your very first time hearing of these advanced applications, the BreatheSmart FLEX highlights 2 ACH over a 700-ft2 space. In other words, it’s powerful enough to purify a whole house.

The true HEPA filters, in this case, are also extraordinary due to the special coating. This addition takes the role of exhibiting the fungi and bacteria’s growth, making it the best option for mold and dust with an unmatched lifetime.

Regardless, it operates silently thanks to the WhisperMax technology that is considered twice as quiet as other competitors on Turbo speed.

  • The AOC carbon filter is washable to save more money
  • Equipped with a permanent filter to eliminate different pollutants
  • Have a remote control

The Winix 5500-2 is an advanced version of the 5300-2 with a more effective filtration system, slightly stronger airflow capability (up to 240.14 CFM – Turbo speed), and remote control.

Besides, the AOC carbon filter, in this case, is specifically designed to allow users to wash and renew it, saving more money in the long term. There’s also a slightly upgraded particle detector sensor to be more sensitive and responsive against odors.

To break down allergens, chemical vapors, odor, and other pollutants, the Winix 5500-2 is constructed with PlasmaWave that works with no harmful ozone emitted.

Out of numerous odor-removal air purifiers, the Winix 5500-2, bolding a washable AOC carbon filter and PlasmaWave gets the highest score during my personal tests

Pros
  • The activated carbon filter is specifically designed with multiple layers to remove all smokes off the air
  • Powerful airflow with 4 fan-speed settings to work flexibly in different room sizes
  • Can clean a 355-ft2 house within 10 minutes

For cigarette smoke removal, the Airthereal APH260 is the winner in my tests by featuring a 7-in-1 filtration system.

  • Run silently (22 dB to 52 dB) with 5 fan-speed settings
  • No ozone emitted

Cons

Out of copious air purifiers for extra-large rooms, I’m satisfied the most with Coway Airmega 400 because while providing a room coverage of 1,560 square feet, it keeps far-fetched silence.

There are totally 5 fan speed settings and even at the highest, the unit just releases a comfortable white noise of 52 dB, which is not too loud in such a spacious area.

  • Run more quietly and safely than the RabbitAir BioGS 2.0
  • Offer 5 airflow settings – more versatile than other RabbitAir air purifiers

Cons

Among various RabbitAir BioGS 2.0 and MinuSA2, the SPA-700A is the worthiest for medium-sized areas in terms of safety and performance.

Though it’s not the cheapest, the 6-stage filtration system with no ozone emissions and almost silent operation, the unit turns out to be affordable. There are 5 airflow settings to customize and each is equivalent to a certain noise level. But even at the highest, it’s still pleasantly quiet.

The best thing about this MinusA2 is the versatile mounting methods that you can either wall mount or let it stand alone – something that other air purifiers can’t do.

How to choose a good HEPA air purifier?

Best HEPA Air Purifiers For Home Use

Room Coverage

Each HEPA air purifier is designed to handle a certain size range of room and the measuring unit is Square Feet (sq. ft. or ft²). For example, the room coverage of Coway AP-1512HH is 361 ft² while the RENPHO Air Purifier is 301 ft².

So, what’s the point?

Multiply the room’s width by the length (measured in feet) to get your room’s area and then, find an air purifier with equivalent square footage rating.

Types of HEPA filters

You possibly have heard that HEPA filters are the most efficient type out of a bunch with the highest allergen particle removal ability. But do you know that there are three different types of HEPA filters?

They are:

  • HEPA-type Filter: A lower version of true HEPA filter that can trap allergen particles as small as 1 micron or larger. HEPA-type filter in fact doesn’t meet the strict regulations set in place by the United States Department of Energy (DOE).
  • True HEPA Filter: This is the most popular type with the highest standard air filter – capture 99.97% of allergen particles as small as 0.3 microns or larger, satisfying the standards set by the US. DOE.
  • BioGS HEPA Filter: The advanced version of true HEPA filter that’s specialized in decreasing the built-up microscopic particles on the filter, meaning that it will last longer (generally within 18 months to 3 years)

Apparently, the more advanced the HEPA filter, the more expensive the air purifiers.

Noise Level

One downside of HEPA filters, however, is the noise factor.

That’s why you should consider this feature especially if intending to place it in bedrooms or kids’ rooms and it depends on several elements:

  • Fan speeds: The faster the speed, the louder
  • Manufacturing quality: A cheaply-made unit might noise up to 10 times than the well-made ones
  • Type of HEPA filters: The more advanced the filter, the quieter

Below are the common ranges of air purifier’s noise level as well as a short descriptions to let you easily get an idea for each. Notice that the measuring unit is decibel (dB).

FAQs

Best HEPA Air Purifiers For Home Use

Can air purifiers be harmful?

Air purifiers are only useful when you choose the right type. Conversely, a wrong type might cause discomfort or worse, some health issues.

The “wrong type” of air purifiers that I’d to mention here are the ionizers and ozone generators.

Where should I place my air purifier?

In most cases, air purifiers should be placed in the middle of the room with no objects, furniture or things like that obstructing the flow of air.

If it’s for bedrooms, the directional registers should point towards you for the highest efficiency and the air purifier itself should be positioned within 6’ to 10’ of distance.

Some people who don’t like to put a tall unit in their room’s center for aesthetics issues, choosing a 360-degree filtration model is a good alternation. Just remember to place it at least 6” far away from the walls.

Can I put my air purifier on a table?

As long as the air purifier is small and compact enough to not disturb anything on the table, it’s possible to be placed there. In fact, there are many small air purifiers designed specifically for office desks or computers.

What is better for allergies humidifier or air purifier?

Humidifiers are designed to provide and adjust the humid level of a certain space while purifiers are for cleaning the air. With high-quality filtration systems, it can capture different sizes of allergen particles with a rate of up to 99.97%.

For such reasons, air purifiers are better for allergies.

Will an air purifier help with sinus problems?

Some air purifiers that are equipped with 3-stage filtration systems, including activated carbon filters and HEPA filters, can help with sinus problems.

These two vital types of filters trap almost tobacco smoke, pet dander and hair, mold spores, pollens, and dust – things that your sensitive nose/sinus usually react to.

Which is better air purifier or ionizer?

To identify which is better, this comparison table will help you:
