Award: TOP PICK
WHY WE LIKE IT: This personal air purifier comes with a true HEPA filter for 99.97 % of airborne containment killing, and Core Flow technology to project air exactly where needed, an excellent choice for people who want a personal fan as well.
This sleek white and silver purifying machine doubles as a purifier and fan. 360 sealed HEPA and activated carbon filters work to cut down pollutants as small as 0.3 microns and a fan oscillates up to 70° for cool air in all directions. A separate half-sphere dome on top can be cranked to project airflow in any direction.
Kudos for an LCD screen that shows real-time air quality reports and an intuitive handheld remote controller with the choice of 10 fan speeds, oscillation angle arrows, a sleep timer, and a filter life and maintenance information button. Its sleep timer can be set at different intervals between five minutes and nine hours. Check out the best air purifier for babies that also has preset timers for 1-12 hours.
Award: HONORABLE MENTION
WHY WE LIKE IT: This personal air purifier uses electrostatic purification to release millions of negative ions into the atmosphere to neutralize contaminants and comes with a rechargeable battery, an excellent choice for people on the go.
This personal air purifier features a lot in a small, compact 1.65 x 0.75 x 3.5-inch frame. AirTamer Electrostatic Purification technology creates a negative ion later to build a sphere of negative ions which “pushes” contaminants away. Power Boost Technology works to kill allergens, pet dander, bacteria, and viruses within 3-6 feet with an adjustable proprietary conductive lanyard to wear on your neck on the go.
One of our favorite features with this unit is its rechargeability. It can run up to 150 hours on a single charge and uses a USB cable for quick charging. Plus, it is whisper quiet to not compete with loud airplane engines on your next flight. In terms of digital controls, it’s limited to a single green “on” indicator light – fitting for its compact size. For more digital controls and a dedicated smartphone app for monitoring and scheduling, have a look at the best smart air purifier.
Award: BEST POCKET SIZE
WHY WE LIKE IT: This personal air purifier comes in ultra-compact pocket size and is designed as a smoke filter, an excellent choice for people who want to help others avoid their second-hand smoke.
This portable air purifier is not a traditional air purifier in terms of airborne contaminant obliteration. About the size of a cell phone, this personal smoke filter is used to blow smoke in, releasing odorless air on the opposite end. A recessed inward curvature contours well to the mouth when blowing in.
Consider this portable air purifier more of a gimmick, fun piece, with the choice of more than ten colors to choose from. Our only knock is that this purifier’s filter cannot be removed to clean and less than stellar filter life (about two to three months) with regular use. For other smoke filter options, have a look at the best air purifier for cigarette smoke.
Award: BEST BATTERY
WHY WE LIKE IT: This personal air purifier comes with a negative ion generator to the tune of 50 million ions per second and includes a built-in rechargeable lithium battery, an excellent choice for wearing anywhere you need cleaner air.
This compact 1.4″ x 3.1″ wearable necklace air purifier improves your breathing spaces with a no-frills attitude, comprising of a sleek, wildly angular silver metallic necklace with the engraved AVICHE logo, which works to build a protective layer of micro negative icons to bind and seal itself against airborne pollutants.
Kudos for a very simple setup, consisting of nothing more than a necklace length adjuster, a micro port for USB charging, and a powerful lamp with two colors to indicate charging or working. Battery life is solid, with a 35 to 40 hour run time on a 3 to 4-hour charge for a 500+ time lifecycle, making this potentially last for years and years with regular use.

Award: BEST ON A BUDGET
WHY WE LIKE IT: This personal air purifier comes with healthy negative ion output and a 20 to 25-hour run time at a good price, an excellent choice for value-conscious people looking for budget clean air.
This personal air purifier purifies air by releasing micro-negative ions, which blast into the atmosphere and clump or bind to airborne contaminants, effectively neutralizing them. Negative ion output falls in the >20million/cm3 range with a 1m3 coverage area, an excellent range for use while on airplanes, or on public transportation.
In terms of design, this personal air purifier is one of the quirkier ones we’ve tested with a heavily contoured, egg-like shape and a single glowing silver dial with a green glow. It uses a built-in rechargeable lithium battery good for a 20 to 25 hour run time. For your vehicle, it is wise to invest in the best car air purifier that offers up to 20 air refreshes per hour.

Three airflow adjustment levels allow users to calibrate this LONG TERM unit’s strength. Kudos for doubling as an aroma diffuser with an added container for essential oils to spruce up any environment.
Our favorite feature with this personal air purifier is its compatibility with the FitAir app, which provides HEPA filter life, battery life, and real-time air quality updates to keep you posted. Some of the best ionic air purifiers can also gauge air quality in real-time.

This best wearable air purifier for viruses offers a little bit of everything. Millions of negative ions are dispersed throughout the air to neutralize germs, bacteria, smoke, and odors to the tune of 1.3 million ions per cubic cm. Its back panel contains a switch and a round button which produces a magnetic field. With a 35 square foot coverage area, we like this for larger offices.
We like the fact this personal air purifier is only 1.41 ounces, easily worn with a soft lanyard with adjustable tightness. It is good for 30 hours of use per charge with an easy to read red light when it is charging.
Award: BEST FOR TABLE TOPS
WHY WE LIKE IT: This personal ionic air purifier releases 120 trillion ions per second using gold-plated stainless steel collectors, an excellent choice for a tabletop or office desk.
Our favorite feature with this unit is its outstanding 120 trillion anions per second output, which is one of the highest we’ve researched. It uses gold-plated stainless steel collectors to collect all types of airborne pollutes, including pollen, dust, and mold spores. Our only knock on this unit is that it does not include a built-in fan.
In terms of ease of wear, it’s very adaptable – only 2.5 x 1.5 x 8.5 inches and weighing 1.5 ounces. It includes a breakaway strap for an easy and adjustable fit, accommodating most neck sizes. All in all, we love this unit’s combination of air output and ease of wearing. For larger spaces, you will likely need the best whole house air purifier.
In determining the best personal air purifier to buy, we explored efficiency, versatility, and run to charge time ratio.
Do personal air purifiers work and do wearable air purifiers work? Look for the best personal air purifier with a favorite negative ion release rating, which works to latch and bind onto airborne contaminants and clump them away. We like a minimum of 2.5 million ions per cm3, which works effectively in reducing airborne allergens. Note, personal air purifiers are very compact, so they do not include large particle filters, true HEPA filtration, or activated carbon filters for a more effective job against smoke particles, odors, and gasses.
In terms of versatility, we like personal air purifiers that use adjustable and flexible lanyards for easy wearing around the neck, discreet enough to not look overly obvious while riding on airplanes or other forms of public transport. Some even have quirky designs (e.g. heavily contours egg-shaped and sleek metallic contraptions) which should catch a comment or two. If you want something larger for your house then you can also consider getting the best plug-in air purifier.
No, we do not consider air purifiers a waste of money. Our recommendation is to use a 3-stage air purification system with a large particle filter, true HEPA filter (ultrafine particle), and an activated carbon filter to get rid of airborne contaminants as small as 0.3 microns. Some medical-grade purifiers (e.g. Hyper HEPA technology) are even capable of neutralizing airborne contaminants as small as 0.003 microns. On the effectiveness scale, negative ion releasing personal air purifiers are not as strong.
Yes, HEPA purifiers are definitely worth it. They are effective at neutralizing airborne particles such as allergens, mold, cigarette smoke, and odors. However, they are less effective with particles sitting on Soft or hard surfaces. For the best results, go for a minimum 3-stage filtration purifier with a bigger square footage rating than the room/s you wish to run it on.
The best space to put an air purifier is at room temperature, in an open area where its airflow cannot be obstructed. Keep all doors and windows closed and keep it away from walls and as close to the odor source as possible.
It can take anywhere from 30 minutes to two hours. Each air purifier is different in terms of square footage rating, air changes per hour, and fan speeds. Many air purifiers are capable of clearing out three room changes an hour for spacious 600 square foot rooms. Please check your air purifier's specifications to learn more.
