Top 10 Best Personal Air Purifiers

 #1  Dyson Pure Cool Me Personal Air Purifier

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.

Pros
  • Up to 70° oscillation
  • Built-in reminder for filter maintenance
  • Bright LCD screen with filter life, airflow speed, and mode selections
Cons
  • No dedicated smartphone app for scheduling and monitoring

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.

 #2  Airtamer A310 Personal Air Purifier

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.

Pros
  • Adjustable lanyard for easy wearing
  • 2 million negative ions released per second for purification
  • Only a single green “on” indicator light
Cons
  • Some people may find cord itchy
  • May fit too bulky for small children

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.

 #3  Smoke Buddy Air Filter Personal Air Purifier

Cons

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.

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.

How We Decided

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.

IOn 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.

Best Personal Air Purifier Buyer’s Guide

The Most Important Features to Consider

  1. Efficiency
    Look for a personal air purifier that could release a minimum of 2.5 million ions per cm3, which is effective in battling allergies, pollen, odors, and other contaminants in your immediate vicinity. Many personal air purifiers come with a favorable square footage rating (e.g. 25). Note, personal air purifiers will never be as efficient as larger air purifier units with large particle filters, true HEPA filters, and activated carbon filters.
  2. Versatility
    Personal air purifiers should be discreet or make enough design sense to wear around the neck, especially in areas of public transport such as buses and airplanes. Look for the best personal air purifiers with adjustable lanyards for a snug fit. Kudos for built-in fans which can provide a welcome reprieve from blistering hot days.
  3. Run to Charge Time Ratio
    Our preference is for personal air purifiers to have a favorite run to charge time ratio. Some of the better ones are good for more than 30 hours of straight usage on a single charge. Consider 20 to 25 hour run time on 2 to 3 hours of charge a good bet. Fumbling with USB cords and charging daily is a hassle we’d rather avoid.

Personal Air Purifier FAQs

Are air purifiers a waste of money?

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.

Are HEPA air purifiers worth it?

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.

Where is the best place to put an air purifier?

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.

How long does it take an air purifier to clean a room?

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.
