The 11 Best Air Purifiers of 2024

Air purifiers can be an invaluable investment - whether you suffer from allergies or just desire purer air quality. Keep reading to discover which models offer the best solutions!

An air purifier is an effective solution to allergy and asthma symptoms by trapping microscopic particles that trigger them. Plus, air purifiers eliminate odors and chemicals caused by tobacco smoke, mold growth, and mildew that could trigger allergies as well. Finally, air purifiers have antimicrobial capabilities which make them especially helpful during pregnancy when immune systems can become compromised.  

When purchasing an air purifier, be sure to read reviews and compare prices before making your selection. Furthermore, larger rooms typically require more powerful air purifiers; additionally, some models can even be set to automatically turn off when not being used.  

BlueAir purifiers feature classic tapered cylindrical shapes that fit easily into most rooms without looking out of place, as well as its auto function that operates without user intervention - saving both energy and money in the process.  

With its impressive performance and sleek design, this air purifier makes an excellent addition to open-concept homes. Additionally, it doubles up as a fan and comes complete with an app providing user insights like filter life tracking.  

At testing, this blue air purifier easily collected smoke and dander while simultaneously lowering PM 2.5 levels to healthy breathing standards in only an hour. With easy controls like a remote and an app for voice control, its setup was seamless.  

Moreover, air purifiers protect from pollen, pet dander, smoke, volatile organic compounds, and more – We’ve tested numerous models below to find the top ones.  

The Best Air Purifiers and Why You Need Them?  

With the COVID-19 pandemic and wildfires, smoky skies, and dusty climates putting families at greater risk, they must take measures to safeguard them against airborne pollutants such as allergens, pollen, dander, and pet hair. An air purifier can help filter out these toxins while providing clean air throughout their home - particularly beneficial for people suffering from allergies, asthma, or other respiratory ailments.  

These smart air purifiers all include HEPA filters to capture any airborne particles that aggravate these conditions, such as pet hair or smoke, while some also feature prefilters that catch larger particles that could otherwise damage the HEPA filter and extend its lifespan. Most manufacturers advise replacing your filter every six months for optimal performance.  

These units feature various features designed to improve user experience, such as voice controls and pollution indicators, as well as apps enabling you to track indoor air quality, remotely control devices, and order filters. Furthermore, all are relatively quiet - which is especially beneficial if used in bedrooms without disturbing sleep.  

Most models in this roundup feature a three-stage filtration system consisting of a HEPA filter and an activated carbon filter to help eliminate odors from smoking, cooking, or other sources. Some also incorporate UV-C bulbs that kill germs and bacteria in the air.  

Two of these units in this roundup use high voltage to charge airborne particles or molecules with electrical charges that cause them to clump together and search out potential bonding partners, helping remove them from the atmosphere. 

1. Blueair Blue Pure 311i Max  

The Blueair Blue Pure 311i Max air purifier is a top-rated model, boasting superior indoor air quality improvement while remaining user-friendly and cost-effective. While more costly than some competing models in its category, its performance makes up for any additional costs involved - all while remaining stylish!  

This air cleaner features a sophisticated sensor that monitors and adjusts to the quality of air inside your home, automatically. When the sensor detects an increase in dust, smoke, or pollen levels it increases fan speed to clear it more quickly, saving energy while prolonging the filter lifespan and saving money with its intelligent feature of extended filter life. In addition, it keeps track of filter status to notify you when it's time to change them out.  

Blueair Air Purifier uses HEPASilent dual-filtration technology to quickly clean an area up to 387 square feet in 12.5 minutes or 929 square feet in 30 minutes at full speed, depending on which setting is selected. It excels in eliminating airborne allergens like dust mite debris and pet dander while simultaneously filtering out cigarette smoke and mold spores; furthermore, it boasts an outstanding track record when it comes to reducing VOCs (volatile organic compounds) as well as chemicals from its output.  

One of the best features is the easy, intuitive controls and user-friendly display panel, which allow for simple switching between automatic, sleep, or manual modes. The control panel features an easily read LCD with bright adjustable LED indicators of filter status and mode selection - plus there's even a child lock to prevent kids from messing up settings!  

Voice assistant compatibility is another useful feature, enabling you to use Amazon Alexa or Google Assistant devices like Google Home Hub to control your Blueair purifier. In our tests, the Blueair Blue Pure 311i Max successfully recognized voice commands instantly and responded without delay - making hands-free operation a reality in your home!  

The Blueair air purifier is certified QuietMark, meaning that its noise levels are extremely quiet - barely audible at just 52 decibels when on its highest setting compared to models like Levoit Vital 200S or Wyze Air Purifier, which produce louder levels at around 58 decibels.  

2. Honeywell HPA300

The Honeywell HPA300 air purifier is one of the top-rated on the market and one of the more affordable choices. Although not cheap, its affordability for most is reasonable given how often an air purifier will be running throughout the day. This unit comes equipped with three certified HEPA filters and an Odor-reducing pre-filter while being Energy Star compliant and offering five-year warranties - great features in an air purifier!  

Honeywell HPA300 Air Cleaner features various wonderful capabilities, including three different air cleaning levels, turbo mode, and an automatic off-timer. Plus, it does not produce any ozone! With an easy-to-read display at-a-glance panel which displays current device settings and air quality as well as light dimmer function suitable for night use as well as filter replacement reminder.  

This air purifier is ideal for those suffering from allergies as it will remove pet dander, pollen, and dust as well as smoke, Odors, and germs. Furthermore, its amazing CADR rating allows it to work well in larger rooms of up to 465 square feet.  

Although the Honeywell HPA300 may be costly, it comes with an impressive five-year warranty - much longer than other units such as Winix 5500-2 or Coway Mighty.  

The HPA300 features an outstanding pre-filter that effectively absorbs gases and VOCs while trapping larger dust particles - an essential step towards the proper functioning of this machine. We advise replacing this pre-filter every three months for optimal performance.  

Airflow in this device is quite good and it moves large volumes of air quickly. Unfortunately, though, the noise may be an issue for some individuals.   

Furthermore, this unit is rather heavy and tall at 22 inches in height and 17 pounds. Even though two handles are included for easier portability if shifting is necessary. 

3. Broan-NuTone Air Purifier

Although air purifiers won't completely rid of lingering smoke Odors (unless you ban cigarettes or cook with wood), certain models are more effective at reducing them than others. Coway has designed this model, featuring an internal HEPA filter designed to trap particulates smaller than 2.5 microns while activated carbon filters trap gases such as those created from smoking, cooking, or pet Odors. Plus, its sound level at the lowest fan speed reaches only 49 decibels!  

As a bonus, this unit also earned Energy Star Most Efficient 2023 certification, meaning it uses less power than a 60-watt incandescent light bulb. While it doesn't come equipped with a timer feature, you can pair it with the Blueair app for additional control of air quality - tracking pollution levels over time as well as receiving alerts when new filters need replacing so you don't forget when to change them!  

Not only is this air purifier impressively efficient, but it is also highly user-friendly - its controls are simple, with an indicator light on its front panel changing color to correspond with pollutant levels. Plus, an app provides an in-depth breakdown of your home's air quality analysis as well as features to manage it more effectively - such as setting an automatic schedule!  

The 311+ Max isn't compatible with our favorite smart home devices like Amazon Echo and Google Assistant; however, its mobile app provides a convenient way of monitoring air quality within your home, and you can purchase replacement filters at a competitive price through their online store. 

4. Coway Airmega IconS

The Coway Airmega IconS is a high-end air purifier that fits seamlessly into both modern living spaces and dusty bedrooms, boasting machine-washable fabric pre-filters to extend their lifetimes, Green True HEPA filters, activated carbon filters, as well as an LED indicator alerting users when it's time for filter replacements.   

One of our tests revealed it as one of the top performers with superior performance while operating quietly; yet due to higher upfront and lifetime costs than similar models.  

Korean electronics brand Coway is known for creating innovative clean innovations for the home, and this stylish yet sophisticated air purifier from them is no different. Not only is it one of the top-performing air purifiers we've tested; its stylish yet sophisticated design stands out as well.   

Moreover, it uses voice commands with Google Assistant and Alexa voice assistants; its control panel features easy-to-read buttons and a well-laid-out display making this device enjoyable to use; additionally, it comes equipped with sleep mode to reduce noise levels when the room darkens; plus its Smart Sensor adjusts fan speed according to real air quality - making this an intelligent option over other models we tested.  

This model is ideal for keeping environments clean at both home and work, as its Eco Mode automatically shuts off its air filter after 10 minutes to conserve energy and save costs. In addition, its air quality monitoring and light sensor control the sleep mode as well as having a timer that can be set after one, four, or eight hours of use - ideal for anyone interested in keeping the environment as a priority!  

The Coway Airmega IconS has an ionizer that produces negative ions to supplement those produced by its purifier's filters, and to attach themselves more readily to harmful pathogens like bacteria and viruses, trapping them using these filters rather than spreading throughout a room. 

5. Kenmore Air Purifier

The Kenmore 311+ Max is an air purifier that's both effective and user-friendly, offering reliable air cleaning at a reasonable cost. In our tests, it successfully removed most pollutants in a room while boasting one of the lowest energy usages among all models we tested. Plus, its fast-clearing speed made it ideal for people living with asthma or respiratory conditions.  

This set includes a washable fabric pre-filter designed to capture fur, dust, and other large particles before passing them on to our True HEPA filter for removal of PM2.5 and PM10 particles at less than half the time of our top model; taking 6.25 minutes at low speed and 2.5 minutes on high.  

Noise-wise, the 311+ Max was among the quietest models we tested and is an ideal option for bedrooms. At six feet away on its highest fan setting it only produced 56 decibels of sound which was barely audible - ideal for bedroom use!  

However, unlike our tests of other units like Dreo Max S and Wyze air purifiers, the 311+ Max lacks an onboard screen with real-time numeric PM2.5 readings - something which we found invaluable - although its companion app (available for both Android and iOS devices) provides access to this data.  

The 311+ Max's voice control capability with Amazon Alexa or Google Assistant makes it ideal for those without separate remote controls or smart home hubs, making life much simpler for those without dedicated devices like those listed above. Plus, its multi-color LED indicator easily reminds users when it is time to change filters based on blue indicating excellent air quality (green is good, yellow moderate, and red poor air quality)! 

6. Frida Baby 3-in-1 Air Purifier

An air purifier is an invaluable asset to any new mother's home as it helps enhance indoor air quality and decrease the amount of dust and allergens that could negatively impact her baby's respiratory health.   

Furthermore, quality air purifiers also can reduce odors caused by cooking, smoking cigarettes, or pet dander odors; and reduce cooking odors, cooking aromas, or pet dander smell.  

These devices were made specifically to reduce respiratory problems for their use together with good habits like cleaning surfaces regularly, increasing ventilation, using low VOC products, etc.  

HoMedics TotalClean air cleaner and fan combo has earned high praise among our lab testers due to its outstanding performance, stylish design, and various features. Specifically, its four stages of air purification - pre-filter, HEPA filter, ionizer - successfully eliminate harmful pollutants from the environment while monitoring air quality in real-time for efficient operation and monitoring filter replacement costs accordingly; making this an efficient yet smart choice for any home environment despite its costly filter replacement costs which may make it out of reach for some individuals.  

The Fridababy 3-in-1 air purifier, sound machine, and nightlight are an outstanding addition to any nursery. Featuring its innovative filtration system designed to remove dust mites, pollution, and mold spores from the air while soothing your child to sleep with two relaxing sounds, three fan speeds, and four different nightlight colors; it makes an excellent investment.  

This top pick is an effective purifier featuring a four-stage system to reduce odors, pollutants, and other airborne particles. A pre-filter, true HEPA filter, and carbon filter trap irritants while an ionizer releases negative ions into the atmosphere - offering an impressive 230 square foot coverage area and two fan speed settings!  

Although it lacks some of the more advanced features found on the 311+ Max, this budget option makes an excellent addition to any room in your home. We love its sleek minimalist aesthetic that blends well with contemporary home decor; plus its relatively quiet operation at only 30 decibels on its highest setting! 

7. Nebula Air Purifier

Amazon's Nebula Air is an economical, yet effective air purifier solution designed for smaller rooms. Specifically tailored to remove dust, allergens, and viruses as well as odors effectively while its automatic mode operates without user input or regulation.  

Air from your room enters this device through inlets on both its front and back sides, passing through a filter that scrubs it clean before exiting through an outlet at its top. However, unlike its more costly competitors such as the Dyson TP07 and BlueAir 311+ Max models, this one blows clean air straight up rather than into rooms, meaning that its effect takes longer to travel through your home than other devices do.  

It features both traditional mechanical filtration and negative ionizer technology to remove particulates from the air, as well as negative ionization to release negative ions into it. While this device can help eliminate odors, some may be concerned that negative ionizers generate too much ozone in the form of harmful emissions.  

This air purifier may not be ideal for kitchen use as it might interfere with food preparation and cook odors; however, it is an excellent choice for bedrooms and smaller living rooms where allergies, asthma, bronchitis, and other respiratory conditions may exist.  

Our lab testing of the Nebula Air has demonstrated its effective removal of particles at any speed setting, particularly allergens and volatile organic compounds from the air. As such, this air purifier should make a good choice for people allergic to dander, dust mites, or pet hair allergies - you should notice an improvement in symptoms like sniffles and itchy eyes after using this air purifier. 

8. Coway 1512HH

The Coway 1512HH air purifier has proven itself as one of the top models on the market. Ideal for medium-sized rooms and featuring very low noise levels while cleaning up to 1,748ft2, its durability is impressive and boasts a long warranty period; like that found on Winix 5500-2 but more cost-effective.  

This air purifier utilizes a four-stage filtration system to effectively eliminate pollutants in the air such as dust, pet dander, and pollen. It comes equipped with a fresh air ionizer to distribute negative ions into the room to help maintain cleaner air longer while also helping reduce odors. With features like an air quality indicator, auto mode, and timer it makes this product user-friendly.  

This air purifier is relatively quiet, emitting just 30 decibels on its lowest fan setting - well below any noise that would disturb most people and almost as quiet as our top pick, the Honeywell HPA100; even quieter than GermGuardian AC4825!  

Coway stands out from similar units with its real-time air quality display, which lets you know whether the air inside your home is clean or polluted with its LED indicator light. This feature can be particularly helpful to those suffering from MCS (Microbial Chemical Sensitivity) or are sensitive to odors.  

The Coway features a modern aesthetic and fits in well with household space constraints. Although well built, some users have reported its highest fan speed being too loud and its tendency to switch levels frequently being somewhat irritating. 

9. Winix 5500-2

The Winix 5500-2 is an ideal air purifier for anyone seeking high levels of features at an economical price. Using pre-filter, activated Carbon filter, True HEPA filter, and plasmaWave technology it uses three filters to trap airborne pollutants such as pollen. In addition, Energy Star certified this air purifier only consumes 6.4W when running on first speed and 1.2W when in standby mode; furthermore, there's even an ozone deactivation button to stop creating additional ozone pollution in your home!  

This air purifier boasts an easy user experience that anyone can easily operate. With just four buttons on its front panel to control everything from fan speed and ozone levels to auto mode and its on-board sensors to detect your home environment and select an ideal fan speed setting, as well as a filter reset indicator alerting you when it's time for filter replacement, it makes using this air purifier easy for anyone.  

Another feature I love about this air purifier is how easy it is to maintain and clean. It features a removable filter that can be removed for washing and is simple to maintain as is its fan. In addition, its lightweight construction makes it easily portable from room to room or into storage; though larger than other units like Coway Mighty in this price range it shouldn't become hard or cumbersome when transporting.  

I had great fun using this air purifier! It did an outstanding job of purifying my test room, reducing particle count by over 98% while simultaneously eliminating VOCs and odors from my testing environment. Furthermore, its quiet operation at its lowest setting made an impression and full statement about its superior performance - only producing a maximum noise output of 65.3 decibels at the highest fan speed setting!  

10. Philips Humidifier Air Purifier

Air quality can have a tremendous effect on how well we feel. Unpleasant odors, dust particles, and other pollutants can irritate respiratory systems while making skin feel itchy or dry; those suffering from allergies may be especially sensitive to airborne pollutants.  

Philips has developed an air purifier with an integrated humidifier to make life easier and keep the atmosphere of your home more comfortable. The device utilizes pre-filter, HEPA filter, and activated carbon filter technology to capture allergens from the air as well as filter out food or cigarette smoke odors while filtering out harmful bacteria to protect you against germs spread around the home.  

This device boasts a simple yet sleek design with a large handle on its top back side to make moving it around easy. Constructed from glossy white plastic, its body is quite compact for an air purifier/humidifier combo device. A small LED display on its front shows current air quality from blue (indicating good air quality) through red (indicating poor air quality) via its color wheel display.  

On the front panel of this humidifier are several basic controls: power, timer, and child lock settings. Furthermore, you can set your preferred humidity level using a slider on the right-hand side. Furthermore, this humidifier covers an area of up to 65 square meters while producing 500ml/h of humidified air.  

As with the MeacoClean CA-HEPA 119x5, this midrange air purifier offers an effective combination of performance and features at its price range, performing admirably in our tests. If air pollution or allergies are particularly problematic for you, higher-end models may provide better results; those looking for climate and heating functions would do better elsewhere; we nonetheless highly recommend this device as an efficient budget option that can also humidify their living space.  

11. IHome Air Purifier 3

If you don't want to invest in an advanced air purifier, iHome offers an excellent budget option: their straightforward air purifier provides tons of useful features that are easily managed through either its built-in touch screen or smartphone application.   

It features indicators for power, timer, fan speed, sleep mode (Pet Mode included), night light (Nightlight Mode), and filter reset. Plus, its display lights up when in use and only illuminates those that are currently active - perfect if you like having everything under one roof!  

The iHome air purifier was designed to fit seamlessly into any environment thanks to its compact rectangular form and clean aesthetic. Crafted with high-grade plastic in fresh white or summer pink colors and features a cable tray at its top for organizing USB-C cords neatly. Unfortunately, however, it doesn't support voice control or integrate with home automation systems, though most will likely still find this model adequate.  

Performance-wise, the iHome Air Purifier 3 may not match our top picks but still delivers impressive results. Rated to clean rooms up to 484 square feet with its CADR of 380 cubic meters per hour. Utilizing three layers of filtration: a primary filter for large dust particles and floating matter; an activated carbon filter that tackles formaldehyde smell; and a HEPA class 13 filter that removes smoke, household dust, and pollen - you should see immediate improvements!  

The AirPurifier 3 is one of the top budget air purifiers on the market, and for good reason. Offering great functionality at an unbeatably reasonable price point - including an ambient AQI indicator! Plus, multiple fan speeds and adjustable oscillation functions make this air purifier suitable for most homes - providing an affordable alternative to more costly options like Coway Airmega IconS or Honeywell HPA300 on our list.
