How We Ranked

Some air purifiers barely filter anything. Others provide medical-grade filtration. Sometimes, it’s tough to separate the best and worst air purifiers. However, we used the following ranking factors to do exactly that:

Air Purification Effectiveness: We simulated real-world environments, then rated each air purifier based on its performance. The best air purifiers filtered contaminants from the air without leaving an unusual odor or residue behind. The worst air purifiers had no noticeable impact.

Science-Backed Technology: Ozone filtration, negative ion filtration, carbon filtration, and other proven filtration technologies can genuinely remove toxins from the air. We liked air purifiers that used science-backed technology.

Transparent Advertised Effectiveness: Some air purifier companies randomly throw out claims about filtering “99.99% of particulate matter” from the air without justification. We were wary of air purifier companies that made dishonest marketing claims.

Ability to Target Multiple Particles: The best air purifiers target germs, particulate matter, smog, allergens, pollen, toxins, and other items in the air. We liked air purifiers that targeted multiple particles for maximum effectiveness.

Battery Life, Power Source, and Charging Capacity: Some air purifiers work for 10+ hours on a single charge, making it easy to carry the air purifiers around your home wherever they need to go. Other air purifiers require a constant power source – which is fine. We considered battery life and charging capacity in our rankings of some portable air purifiers, although we weren’t biased against air purifiers that required a constant power source.

Ease of Use: Did the air purifier take a while to charge? Did it have a short charging cord? Was it complicated to operate? Or did the air purifier have a simple, effective one-button design? We liked air purifiers that were easy to use.

Price & Value: You don’t need to spend $300 to get a good air purifier anymore; instead, some of the best air purifiers on our list are available for under $100. We weren’t biased against specific price points, although we considered price and value in our rankings. If you’re paying a premium price for an air purifier, then you should get a premium value. If you’re paying a budget price, then you shouldn’t need to compromise on quality.

Maintenance Requirements, Filter Replacements, and Durability: Does the air purifier last a long time? Or does it fall apart after a few months of use? Do you need to replace the filters continuously? Or does the purifier clean itself and stay effective after years of use? We considered maintenance requirements and durability in our rankings.

Square Footage of Area Covered: Some air purifiers cover 100 to 200 square feet, making them ideal for average-sized offices and bedrooms. Others cover 400 to 1,000 square feet, making them ideal for smaller homes, larger rooms, and apartments. We liked air purifiers that were open and honest about their square footage coverage.

Noise: Some air purifiers are extremely effective at cleansing the air, but they’re also ridiculously loud. We preferred air purifiers that combined effective purification with quiet operation – or at least had multiple speeds to customize the noise level. Some air purifiers had three fan speeds, for example, or a night mode for easy sleeping.

Customer Reviews, Ratings, & Real World Experiences: We tested each air purifier on our list in our simulated testing environment. However, people live in different places. The air you breathe has different humidity levels, particulate matter levels, and other features than the air we used. That’s why we also considered customer reviews in our rankings. Some of the best air purifiers are backed by thousands of five-star reviews.

Complementary or Added Features (Like Night Lights or Carrying Handles): Some air purifiers have carrying handles, night lights, and other features to expand their functionality. We primarily judged air purifiers based on their filtration technology, but we also considered complementary or added features in our ranking.

Design, Appearance, & Aesthetic Appeal: Some air purifiers look futuristic and cool. Others look bland and boring. It wasn’t the most important ranking factor, but we did consider design and appearance in our rankings. Because air purifiers are placed in visible areas of your home, you want them to look good.

Moneyback or Satisfaction Guarantee: It’s not acceptable for an air purifier company to not have a moneyback guarantee. Today, virtually all companies offer a strong moneyback or satisfaction guarantee, making it easy to get a refund on your purchase if you’re unsatisfied. We liked air purifiers with a long, flexible, and comprehensive satisfaction guarantee.

Top 17 Benefits of Using an Air Purifier

You may not think you need an air purifier. However, the world is filled with toxins, particulate matter, allergens, smog, and other contaminants.

Using an air purifier can change your life. Here are some of the benefits people use after running an air purifier:

Help Relieve Symptoms of Asthma: Many people run air purifiers to help with breathing problems like asthma. When you have asthma, you have inflamed bronchial tubes. Pollutants like pet dander, pollen, and dust mites irritate these tubes further, making it harder to breathe. By running an air purifier, you can help relieve symptoms of asthma by removing irritants from the air.

Eliminate Harmful Compounds from Indoor Environments: Many of use are breathing in toxic air without realizing it. Your indoor environment might have carbon monoxide and nitrogen dioxide particulate matter, for example, which can affect your health over time. Carbon monoxide exposure is deadly in high doses. However, studies show that even low doses of carbon monoxide over time can increase the risk of dementia and Alzheimer’s disease.

Get Rid of Vehicle Smog and Other Pollutants: If you live in a city, then your air is likely much more toxic than air in the countryside. Good air purifiers get rid of vehicle smog and other pollutants from the air, helping you breathe cleaner even in the middle of an urban environment.

Reduce the Spread of Airborne Diseases: Many diseases spread through the air. There’s a reason your whole house might get sick when one family member catches the flu. Air purifiers use HEPA filtration technology to reduce the spread of airborne diseases. A good air purifier could save someone’s life – especially if you live with older adults, children, or anyone with a weakened immune system.

Get a Better Sleep: Do you struggle to sleep at night? Do you regularly wake up? Do you snore? Air purifiers could help with all of these things. Studies show cleaner air is linked to a better night’s sleep. When you have poor-quality air in your home, you’re more likely to sneeze, cough, or feel congested overnight.

Filter Carcinogens (Cancer-Causing Compounds): The world is filled with carcinogens. Health authorities classify compounds as carcinogens if they’re linked to cancer. Some of the best air purifiers remove carcinogens from the air. Every time you remove a carcinogen from the air, you reduce the chance of breathing in that carcinogen. The fewer carcinogens there are in your body, the lower your risk of cancer.

Eliminate Hazardous Compounds and Toxins, Including Asbestos: Asbestos was commonly used in commercial and residential construction from the 1940s and 1960s. Depending on the age of your home, you could be exposed to asbestos daily. Air purifiers can eliminate hazardous asbestos particles.

Remove Pet Odors: Do you have pets? Pets leave your home with an unpleasant smell. No matter how much you clean, it’s tough to remove that smell from the air. Air purifiers use proven technology to latch onto odor-causing particles, giving your home a fresh and clean scent. Whether you have one pet or multiple pets, a good air purifier can make your home smell better than ever.

Add or Remove Humidity: Many air purifiers also double as humidifiers or dehumidifiers. If you live in a dry climate, then adding humidity to the air can help with cracked skin, wrinkles, and a scratchy throat. Or, if you live in a humid climate, then removing humidity from the air can help with mold and indoor comfort levels. Running an air conditioner constantly can dry out your home, leading to flaky and cracked skin. Good air purifiers help by adding or removing humidity.

Control Seasonal Allergies: If you regularly experience seasonal allergies, then an air purifier can help. Air purifiers remove allergens from the air. Allergens are substances that irritate your allergic response. The best air purifiers free your air from pollens and molds that could trigger symptoms.

Less Dust Accumulation: Do you dust constantly? Does dust regularly build up around your home? The best air purifiers control the rate of dust accumulation, which means you may not need to dust as frequently. Most dust is actually human skin flakes. After installing an air purifier, you might notice significantly lower levels of dust around your home.

Longer Life for HVAC Filters & Devices: Air purifiers reduce strain on your air conditioning filters, furnace system, and other HVAC appliances. A good air purifier could add months or years to the lifespan of your HVAC system.

Reduce Stress: Studies show air pollutants raise stress levels. Whether you’re exposed to indoor or outdoor air pollutants, you could have higher stress levels. Stress is associated with weight gain, high blood pressure, and other health concerns. When you run an air purifier, you could remove pollutants from the air, helping you reduce stress.

Repel Mosquitos and Pests: Air purifiers can control mosquitoes and other pests around your home. Mosquitos and other airborne insects don’t like ozone or negative ions, and your air filter may push these pests away.

Control Mold: Some homes are more prone to mold than others. Maybe you live in a humid environment. Maybe your home has poor airflow. Whatever the case may be, a good air purifier could control mold, which could save you thousands in mold remediation costs and improve your health at the same time.

Help Prevent Headaches: Do you regularly struggle with headaches at home? Airborne pollutants could increase the risk of headaches. Good air purifiers help prevent headaches by removing toxins from the air.

Boost Life Expectancy: Some air purifiers have been shown to boost life expectancy. Every time you remove airborne particles from the air, you’re preventing those particles from entering your body. Particles enter your body via the lungs, then spread throughout the bloodstream. Some cross the blood-brain barrier, increasing the risk of degenerative brain disease. When you filter the air, you cut off this problem at the source, which could boost life expectancy.

How Do Air Purifiers Work?

Air purifiers work in different ways to cleanse the air you breathe. Some use ozone or negative ion technology, for example, while others use carbon filters and other mechanical filters.

Here’s how the most popular air purifiers listed above work:

Activated Carbon Filters: Activated carbon filters use the unique molecular shape of charcoal to trap odors and particles. This carbon is activated, which means it uses a natural charge to attract particles in the air. Harmful substances are drawn towards the activated carbon, and the activated carbon tracks the particles within.

HEPA Filters: High Efficiency Particulate Air (HEPA) filters capture pollutants as small as 0.3 microns. You cannot see these particles with the human eye, but the best-quality filters capture the particles regardless. Some of the air purifiers listed above use HEPA filtration technology to target the smallest compounds.

Ozone Filters: Some air purifiers generate ozone to cleanse the air. Commonly used in commercial environments (including hotels), ozone filters create large amounts of harmful ozone to neutralize odors in a room. Some portable air purifiers use low amounts of ozone and are safe for use in any room. However, higher-end commercial ozone filters require you to leave the room during operation, then air out the room before entering. They’re some of the most effective ways to cleanse odors, bacteria, and airborne contaminants from a space.

Ultraviolet Light Air Purifiers: Some air purifiers use ultraviolet light to kill germs floating in the air. Ultraviolet light has a specific wavelength to neutralize bacteria, deactivating their activity at a cellular level. Hospitals use ultraviolet light to cleanse tools and surfaces, and today’s best air purifiers use similar technology.

Negative Ion Filters: Also known as negative ionizers, negative ion filters create particles with a negative charge, allowing them to attract and latch onto positively-charged particles in the air. Instead of breathing in positively-charged harmful particles, you can remove them from the air.
