Top 10 Portable Air Purifiers According to Specialists Reviews

Air purifiers are not a new invention, but this appliance came a long way since it first debuted in the early ‘60s. With relatively modest construction, the air purifier has swept households in all continents. Today, manufacturers are using multi-stage filtration and state-of-the-art-technology that makes air purifiers true health-enhancing appliances that can not only clean the air in your room, office, or even your car, but even fight allergies and viral droplets, and bacteria. Lately, portable air purifiers became more popular. Portability, of course, is the main asset here, but we think that a portable air purifier is a great investment also because it is cheaper than their bulky big brothers, and more importantly more silent for bedside use and in quiet office areas.

After comparing specs and countless expert reviews, we picked ten portable air purifiers with slightly different merits to help you choose the best for you. If you have never considered buying one, a portable air purifier is the best entry to this world!

What are air purifier units and what are their intended uses?

Even though air-purifying might be included within a building’s central heating system as a part of HVAC, our main focus in this review is to discuss air purifying units intended for single rooms, and this blog will focus particularly on portable-easy to move- best air purifiers. The air within a room contains a lot of particles, like dust, allergens, mold starters, pet hair, and viruses. Air purifiers work by capturing these particles while circulating the air in a certain enclosure. Air purifier units use several purifying technologies like UV light, HEPA filters, carbon activated filters, or PECO filters.

Why should you consider a portable air purifier?

Well, the most important reason is that it’s portable, as the name suggests. Just like any tech gadget out there, the portable version offers easy transport and a smaller footprint. When it comes to air purifiers, portable versions offer several advantages.

Besides their smaller size, portable air purifiers are cheaper to run as they consume way less electricity, your can place them closer to you, and are quieter, meaning they are a better option for bedside and office use. Moreover, advanced portable air purifiers offer other cool features like a night light, digital clocks, without compromising filtration quality, but they might offer less room coverage than bulky air purifiers.

What do experts say about portable air purifiers? What are their benefits according to experts?

According to Shelly Miller, Ph.D., an environmental engineer at the University of Colorado-Boulder, portable air purifiers are very good at removing viral particles from indoor air. According to several studies and expert opinions indoor areas are likely 5 times more polluted than outdoor air. Meaning that using the right air purifier will help disinfect indoor air from allergens, viral droplets, dust, and smoke, improving the overall quality of your room.

Another piece of information worth mentioning is that 80% of people who look for guidance with buying an air purifier are looking to improve sleep. The American Psychology Association (APA) 60% of adults report having sleep trouble a few nights a week.

A clinical study conducted in May of 2019 found substantial improvements in subjects’ sleep just by improving the air quality. Here is where a portable air purifier comes in handy because it focuses on your breathing zone particularly rather than the whole room.

The MA-25 is worthy of this list, while you may find smarter models and lighter ones, the performance, and features for this device aren’t bad at all and can compete well in the low-mid-range portable air purifier. The design is pretty straightforward (which is not a bad thing in my opinion) and features a tempered glass panel on top.

After comparing lots and lots of portable air purifiers, we found that this Levoit model is one of very few that have a True HEPA filter with under 50$! Moreover, other 50$ models with HEPA filter, do not boast a three-stage filter and especially good odor control. In other words, if you especially want a reliable portable air purifier with a HEPA filter under 50$ that’s your boy!

Levoit Core 200S Smart WiFi Air Purifier

After comparing performance with other models, we found that the Core 200s do serve well in the performance department, this doesn’t mean it’s bad, but rather not top-notch at a lower speed. Nevertheless, the Core 200S still has an impressive 183 sq. ft. room coverage and its CADR is 118 cfm.

The Lvoit Core 200S uses a top control panel and has a nice cylindrical design with simple controls like a night light, timer, and control panel lock (a useful feature for children). Of course, the VeSync app (available on iOS and Android) helps control all features in this portable air purifier through your smartphone.

  • 183 sq. ft. room coverage

5. Winix A230 True HEPA 4-Stage Air Purifier

  • Room Size 230 Sq. Ft.: AHAM Verified room size of 230 sq. ft. Suitable for small to medium size living spaces
  • Fine Mesh Pre-Filter: The first line of defense against the largest airborne particles found indoors
  • Activated Carbon Filter: Reduces VOCs and household odors from cooking, pets, and smoke. It is designed to catch airborne particles found indoors, which also helps prolong the True HEPA Filter life
  • True HEPA Filter: Captures 99.97% of airborne allergens including pollen, mold spores, dust, pet dander, microbes, and smoke (particles as small as 0.3 microns in size)
  • PlasmaWave Air Cleaning Technology: Acts as a permanent filter to safely break down odor, allergens, chemical vapors and other pollutants with no harmful ozone

“Compact design without compromise” that’s what WINIX claims when they describe the A230, and we think they might be right! The South Korean company managed to maintain good performance, have smart features, improve the design, and squeeze a four-stage filtration system under 100$!

The design isn’t completely cylindrical, but rather wider at the bottom than the top for a more balanced and stable design. The WINIX A230 does not have WIFI connectivity or smart features, but it has a very important smart option that is the smart sensor, not all portable air purifiers have this.

The reason this is important is that it lets you keep the air purifier on while it goes from low to high to even stand by without caring about consumption. The smart sensor will detect the room air quality and decide how strong the fan should be accordingly.

Winix A230 True HEPA 4-Stage Air Purifier

One more feature that makes the A230 stand out is that it has a 4-stage filtration system as follows:

  1. Pre-filter fine mesh filter that captures large particles like pet hair and skin particles
  2. True HEPA filter capable of capturing up to 99.97% of particles down to 0.3 microns which includes allergens, viral droplets, pollen, mold, and fungi
  3. Activated carbon filter eliminates most odor formation from pets and kitchens and some chemical particles
  4. Winix PlasmaWave which is a type of ionizer that reduces pollutant and neutralizes bacterial particles (available with on/off switch)

We wish the A230 had some smart features, which would’ve made it one of our top choices, but it certainly made up for it with its power and advanced filtration and sensor system.


  • 230 sq. ft. room coverage
  • AHAM verified
  • CADR of 147 cfm (higher than most portable air purifiers)
  • Quiet operation (25 dB at minimum power)
  • Smart sensor for air quality
  • LED indicator for filter change
  • LED off feature for bedtime

6. TruSens Z-1000 Air Purifier for Home

  • CAPTURES AND DESTROYS POLLUTANTS: 360-degree DuPont HEPA filtration captures pollutants such as airborne viruses, allergens, and certain VOC gases. Ultraviolet light (UV-C) kills germs and bacteria trapped in the filter. Filters pet dander, odors, allergies, smoke, bacteria, dust, mold, and more. Perfect for dorms, bedrooms, nurseries, and small rooms.
  • DUAL AIRFLOW: PureDirect proprietary technology splits clean air into two air streams, delivering purified air more comfortably and efficiently throughout the room. Bi-directional airflow delivers purified air more effectively throughout a room, and in some cases, has been proven to be up to 24% more efficient than traditional air purifiers with vertical airflow.
  • TOTAL ROOM COVERAGE: Most purifiers can leave rooms with areas of little to no air circulation, or dead zones, by only shooting air either vertically or straight out. TruSens PureDirect proprietary technology uses two separate airflow streams to minimize those dead zones. From quiet speed to Turbo cleaning mode, the Z-1000 has been carefully optimized to deliver cleaner air.
  • TRUSENS: TruSens is designed for your lifestyle. Our focus was to create an air purifier that is beautifully designed, simple to use, and beneficial to your living space. Trust TruSens for cleaner air.
  • CLEANER AIR EVERYWHERE: The Z-1000 Air Purifiers are recommended for spaces up to 250 sq ft at 2 air changes per hour (ACH) or 443 sq ft at 1 ACH.

The Z-1000 has a very unique design, good build, good power, and is still considered a mid-range portable air purifier at 119$. At almost 7 lbs you can still easily take it from one room to another especially with its strong build handle design. The idea of a good portable air purifier is that you can move it around all day throughout the house until you place it under your bed at night.

The filtration system is pretty decent and is also a 3-stage system, but we must mention that it uses a HEPA-type filter and not a True HEPA filter.

The TruSens Z-1000 has a 3-stage filtration system that consists of :

  • Activated carbon filter which captures large particles and control odors generated from cooking or smoke
  • HEPA filter the HEPA-type filter captures 99% of particles larger than 0.3 microns
  • UV-C light filter which uses UV sterilization which kills 99.8% of hazardous germs, bacteria, and microbes

It’s worth mentioning the TruSens filtration named DuPont (trademarked) which combines HEPA filter with UV sterilization to catch particles, allergens, and VOC’s. The UV -C light filter is also certified by the California Air Resources Board (CARB) meaning it is ozone-safe and won’t be harmful to use.

The Pure Cool Me is the British company’s model for a portable air purifier, but don’t let portable fool you, this personal air purifier is still a powerful performer with a compact and special design.

The Dyson Pure Cool Me is expensive, at 349$ it is considered higher than many competitors.

We found the design to be very tasteful, compact, and we believe is nicer than other Dyson air purifiers. It also has an LCD that displays various information and a magnetic remote control mount. It is also not heavy at 6.2 lbs making it easily portable.

The filtration system includes

  • Pre-filter that captures large particles
  • True HEPA filter with excellent quality and extremely powerful for its class, capturing 00.97% of particles down to 0.3 microns
  • Carbon filter for odor and gases control

Dyson did not reveal the suggested room coverage for this portable air purifier, because they classify it as a personal air purifier. The jet system for the Dyson Pure Cool Me is just great, the advanced dual jets form a high-pressure airflow that you can pinpoint its direction. We think that the projected dual jet system makes the Pure Cool Me a great portable air purifier for your office desk and bedside table.
