What are the Best Small Air Purifiers & Portable Air Filters in 2019?


Where to buy small air filtersIf you are looking for a good portable air cleaner that is light, compact and easy to take anywhere, this page has the best small air purifiers available and why they are recommended.

It’s important to understand how to properly use a mini air purifier, its specific limitations, but also its potential benefits.

Ahead are the best portable air purifiers, small HEPA filters and compact air cleaners in 2019, with the pros and cons of each to consider before buying one of them.

Can Small Air Purifiers Make a Difference to Indoor Air Quality?

The air you breathe inside your house or apartment is not usually as clean as you might think. In fact, according to the EPA, it can be much higher in pollutants than outdoor air, even if you live in the city.

It’s not just dust and particulate matter either. Mold spores, airborne bacteria, pollen, pet dander, dust mite and cockroach allergens, and harmful volatile organic compounds from flooring and furniture and all dramatically reduce indoor air quality.

To properly clean the air in larger areas you need a high-powered air purifier. However, a well-designed small HEPA filter, like the 3 recommended ahead, can still be effective at improving the quality of the air you breathe if it’s close by.

The Benefits of Portable Air Purifiers

When your air purifier is small, lightweight and compact, then it’s easily portable and can be positioned near to where you spend the most time.

This is highly beneficial and even a low cost mini air filter can work well for indoor air purification when used at close range.

In fact, a good portable air cleaner operating right beside you could be even more effective than a far more expensive air purifier running in a far corner of the room.

New compact air purifiers, like the WYND smart air cleaner ahead, are so small and light you could even use them as a travel air purifier and pack them to take on holidays.

They also easily fit into your car’s cup holder and can filter the air while you’re driving. This is important as the air inside most cars is highly polluted. See more recommended car air purifier options here.


Quick Comparison of the Best Small Air Purifiers and Portable Air Filters

If you’re short on time, here is a list of the best mini air purifiers in 2019:

  1. WYND Essential Smart Air Purifier — Highest air cleaning to size ratio of any air purifier; 9 liters of purified air per second; works for up to 8 hours with a single charge; highly portable at less than a pound and the size of a water bottle; great travel size air freshener you can take anywhere.
  2. iTvanila X1 High CADR HEPA Air Cleaner — Twin True HEPA/activated carbon filters; impressive clean air delivery rate of 106 m²/hr; small and compact; whisper-quiet 26 dB in sleep mode; ozone-free and 2-year warranty; best in smaller spaces.
  3. RIGOGLIOSO USB Air Filter with Negative Ions — True HEPA, activated charcoal and 5 million negative ions per second; light, quiet and portable; USB powered; inexpensive close range air purifier.

These 3 are selected after many hours of detailed research, contacting air cleaner makers and reading technical specifications and user manuals.


Small Air Purifiers are Really Personal Air Cleaners

iTvanila-X1 portable HEPA air filterWith the possible exception of the top pick WYND air purifier reviewed ahead, small and compact air purifiers should always be considered as only effective within a limited radius.

Given this, they really should be considered personal air cleaners, good for smaller bedrooms, in the kitchen, bathroom or beside you on the couch.

Highly unlikely though to work well in a big lounge room, or clean the air in a whole apartment, despite what manufacturers might say.

If you don’t mind moving a portable air filter, between say your bedroom, home office, kitchen and living room table, you can overcome this key limitation and breathe purified air for much of the day and night.

Alternatively, with at least two of the small air purifiers reviewed ahead being such good value, you could get one for each bedroom in your home, providing your whole family with the benefits of better quality air while they sleep.

One important caveat here would be that anyone suffering from asthma, regular allergies or other breathing problems really needs a specially designed air purifier for asthma and allergies.

3 Recommended Small and Portable Air Purifiers for 2019

Other small air purifier reviews usually list a random top 10 of very similar products. This wastes your time when looking for the best portable air filter to buy.

Each of the light and compact air purifiers below are either chosen as the best choice from many competitors, or, in the case of the WYND air purifier, simply have no comparable competition.

After hours of research, reading technical manuals and contacting the manufacturers, these are the 3 best small air purifiers on the market in 2019.


1. Best Compact Air Purifier Overall — WYND Essential Smart Air Filter Review

WYND mini air filterThe beautifully designed WYND air purifier was created by Eric Munoz, a former aerospace engineer, and a team from MIT. It was also the most popular Kickstarter for an air purification product ever funded.

This powerful yet highly compact air purifier uses a rocket turbine inspired design to dramatically increase airflow. So much so in fact that it can generate more than 9 liters of filtered air per second, according to its makers.

The WYND Essential charges with an included USB cable. Once charged, it does not need to be plugged in and can clean the air on the go for up to 8 hours with a single charge.

Weighing less than a pound and only the size of a water bottle, the WYND makes for an excellent travel size air freshener you can literally take anywhere.

Pack it in your backpack to work, use it beside you on your office desk, take it on an airplane, use it in a baby stroller, or slot it into your car’s cup holder while you drive.

This compact air purifier utilizes special medical grade electrostatic filters infused with antibacterial silver particles. These are quite cheap but would need to be replaced every 3 to 6 months depending on how often you use it.

The WYND looks to me like it was designed by Apple and it actually connects to your smartphone with a free app so you can monitor air quality and receive alerts when it’s time to change the filter.

It also comes with a special stand to angle the ‘bubble of clean air’ WYND generates directly at your face and maintain purified air to breathe, even in the most polluted environments.

Unique features like these help make the WYND Essential the best portable air filter I’ve seen on the market.

You can read more about the innovative technology in this product, see customer reviews and check the current price here on Amazon. Last I checked it was actually lower than people paid on Kickstarter.

WYND Air Purifier Pros and Cons

Pros

  • Ingenious turbine design, inspired by jet propulsion, gives the WYND the highest air cleaning to size ratio of any air purifier on the market.
  • Generates 9 liters of purified air per second and can be angled with its stand to point directly at your face and maximize your ‘clean air bubble’.
  • Weighs less than a pound and is a highly compact air purifier at 6.65 inches high and only 2.75 inches wide at the base.
  • USB powered via an included cable and will last up to 8 hours on a single charge. A great travel sized air freshener you can take anywhere.
  • Replacement filters are very affordable and you can get them here on Amazon. It makes sense to buy extra with your WYND if you’ve decided on this as the best portable air purifier for you.
  • The most stylish small air filter I’ve ever seen. Though the WYND Essential only comes in black. To get the white design you need to pay a bit more for the WYND Plus with detachable air quality monitor.

Cons

  • As powerful as the WYND is, it’s much better at constantly filtering the air immediately around you, than purifying the whole room. Company literature focuses on “quickly cleaning your personal space of allergens, germs and air pollution”, rather than CADR or room size.
  • More expensive than the other best small air purifiers in this review, though filters are actually cheaper so this could even out over several years.
  • Does not generate negative ions so look to the RIGOGLIOSO option ahead if you want the health benefits of negative ions.
  • Some customer reviews and comments say that the air filter stand is a bit flimsy. Though this is a feature I haven’t seen with any other mini air purifier so it’s definitely a positive if you’re careful with it.

In Summary

If you’re looking for a small and compact air purifier for traveling, taking to work or using in your car while driving, the WYND Essential is a powerful and stylish choice.

You can check the current price on Amazon here and see the ‘Frequently Bought Together’ section for the low-priced filters.

If you’d like to have the detachable air quality monitor and would prefer the white design option then consider going for the flagship Plus model here. This listing also has more detailed information on how WYND’s unique air cleaning technology works.


2. Best Small HEPA Filter without Ionizer — iTvanila X1 Portable Air Cleaner Review

Mini HEPA air filterThe new iTvanila X1 purifies the air in your home with 2 True HEPA/activated carbon filters and has an impressive CADR (clean air delivery rate) of 106 m³/hr.

It has a stylish modern design, touch controls, filter change reminder and 3 fan speeds. At a very soft 26 dB in sleep mode, it would make for a quiet air purifier for your bedroom too.

Customer feedback is overwhelmingly positive and reviewers say the nightlight can be switched off and you cannot hear this small HEPA filter when you set it to sleep mode.

Light and compact at 3.7 pounds and just 6.7 x 10.4 inches. This stylish little air cleaner also comes with a carry handle, an unusual but useful feature for a portable HEPA filter.

Ozone-free (does not have an ionizer) and a 2-year warranty, according to iTvanila. This small but powerful air purifier is surprisingly good value here on Amazon.

iTvanila X1 HEPA Air Filter Pros and Cons

Pros

  • Twin prefilter/True HEPA/activated carbon filters with a high CADR of 106 m³/hr, outstanding for its small size. These filters can quickly capture 99.97% of airborne particles in a smaller room.
  • Two stage filters are better value than many smaller single filters and can be found for sale here when you need to replace them.
  • Stylish design, ozone-free, 3 fan speeds, touch controls, filter change reminder, safety lock, carry handle, free shipping and a 2-year warranty.
  • Compact, portable and extremely good value for its clean air delivery rate compared to similarly priced competitors.

Cons

  • Still a mini air purifier with a limited air cleaning range. Manufacturer claims of this unit purifying the air in rooms up to 538 ft2 (50 m2) seem wildly ambitious.
  • Despite being ozone-free, Amazon currently shows it cannot be delivered to California. This must be an oversight as the slightly larger and more powerful iTvanila A1, sold here with extra odor protection, highlights its CARB certification and Californian delivery.

In Summary

If you are looking for a great value small HEPA air purifier, and don’t mind not having an ionizer, the iTvanila X1 is highly recommended.

Check the current price, read customer feedback and see pictures of the X1 in people’s homes here on Amazon.


3. Best Value Mini Air Purifier — RIGOGLIOSO USB Air Cleaner with Negative Ions Review

RIGOGLIOSO desk air filterThe strangely named RIGOGLIOSO USB air purifier is very compact and portable at just 5.9 x 9.3 inches and only 1.55 pounds.

It has a True HEPA filter for dust, pollen, pet dander and mold spores, combined with activated charcoal for odors and toxic gases.

This mini air filter is also a negative ionizer, generating 5 million beneficial negative ions per second. This output can’t match the power of the best negative ion generators here, but it is reasonable for such a small air purifier.

This little USB air filter is extremely good value here on Amazon and highly portable, but would only have a limited range and should be positioned close to you for best results.

RIGOGLIOSO Air Cleaner/Ionizer Pros and Cons

Pros

  • True HEPA filter combined with activated charcoal for odors and 5 million negative ions per second.
  • Filters are comparatively inexpensive and you can find them for sale here. They should be replaced every 6 months if you use this portable air cleaner regularly.
  • Small, lightweight, low power consumption and whisper-quiet operation on low fan sleep mode at less than 30 dB.
  • Simple operation — press the big button on top to turn on, speed up, slow down and turn off.
  • USB powered. This would be an advantage if you want to use it with your laptop or on the go in a modern car.
  • New 2019 model, very low price and 1 year warranty, according to the manufacturer.

Cons

  • This is a mini air purifier and would have only a small air cleaning radius. CADR of 50 m³/hr means it’s not as powerful as the previous 2 portable air filters reviewed.
  • The Amazon listing shows it comes with a USB power adapter to plug into the wall but I couldn’t confirm this. If this is not the case you’ll need one, like those used to charge smartphones, to plug into a regular power socket.
  • Blue light can be dimmed but not switched off completely so perhaps not best for bedrooms unless you want a soft nightlight.
  • No CARB certification so cannot be shipped to California.

In Summary

The RIGOGLIOSO is an inexpensive and compact air purifier with the added benefit of negative ion generation.

Best results would be at close proximity and this portable air filter is small and light enough to take with you to work, use in your car or even pack when traveling.

You can check the current price here on Amazon and read customer reviews and feedback on the new 2019 model RIGOGLIOSO USB air purifier.


Portable Air Purification Versus Whole Room Air Cleaning

These top small air purifiers and portable air cleaners need to be positioned quite close to you to work at their best.

Even the powerful WYND should be thought of as providing more of a ‘personal clean air bubble’ around you while you sit at your work desk, watch TV or even sleep in your bed at night.

If you want to clean the air in a whole living room or small apartment then you’re much better off with one of the recommended ionizer air purifiers here.

I hope this review of the best portable air purifiers and small HEPA air filters has helped you find a convenient way to clean the air you breathe of pollution wherever you are.

There are also some other good options here in the best desktop air cleaners as well as the top personal air purifiers here, including wearable options for the ultimate in portability.
