  • Air purifiers have become must-have appliances for keeping indoor air clean by removing pollutants, allergens, and harmful particles—especially important for those with allergies or respiratory issues. From HEPA filters that capture tiny particles to activated carbon for odors and UV light to kill bacteria, each type addresses different air quality concerns. When shopping for one, consider factors like room size, noise levels, filter replacement costs, energy efficiency, and Clean Air Delivery Rate (CADR), which indicates how quickly it can clean the air. We tested 15 popular models to find the best air purifiers for various needs and budgets.

  • Levoit Core 300-P Air Purifier

    10

    We recommend the Levoit Core 300-P for its powerful performance and quiet operation in a compact design.

    Pros

    • Effective at removing allergens and odors
    • Very quiet, especially in sleep mode
    • Covers up to 1095 sq ft

    Cons

    • Replacement filters can be pricey
    • No air quality sensor
    • Limited smart features

    We tested the Levoit Core 300-P in various rooms of our home and were impressed by its ability to clean the air. It quickly removed cooking odors from our kitchen and noticeably reduced dust in the bedroom. The 3-stage filtration system, including a HEPA filter, trapped pet dander and pollen effectively.

    One of our favorite features is how quiet this air purifier runs. On the lowest setting, it’s barely audible at 24 dB. We could sleep peacefully with it running all night. The sleek white design also blends in well with most decor, so it doesn’t stick out like an eyesore.

    The Core 300-P is easy to use with simple touch controls. We like that we can turn off the display light for nighttime use. While it lacks smart features or an air quality sensor, we found its performance and value make up for these minor drawbacks. For homes with allergies or pets, this Levoit model offers solid air cleaning in a user-friendly package.

    Levoit Core 300-P Air Purifier
    • A 45W long-life high-torque motor, a versatile 8.7" x 8.7" x 14.2" size, a 7.48 lb weight, a 141CFM CADR and up to 1095 ft² of purification area for original filter. Levoit Original Filter is HEPA-grade while operating in Sleep Mode, as tested by an independent lab
  • LEVOIT Vital 200S-P

    9.7

    We think the LEVOIT Vital 200S-P is a top pick for most people looking for a powerful, smart air purifier for large rooms.

    Pros

    • Cleans air quickly in spaces up to 1800 sq ft
    • Smart features like app control and scheduling
    • Effective at removing pet hair and odors

    Cons

    • May be overkill for smaller rooms
    • App required for some features
    • Can be noisy at highest settings

    We tested the LEVOIT Vital 200S-P in a large living room, and we were impressed by how quickly it improved the air quality. The display showed the air quality improving within minutes of turning it on. We found the Pet Mode especially useful, as it alternated between high and medium speeds to tackle pet hair and odors without using too much energy.

    The smart features on this purifier are a big plus. We liked being able to control it with our phones and set schedules. The light sensor that adjusts the display brightness is a nice touch for bedrooms. We also appreciate that the pre-filter is washable, which should help the main filter last longer.

    In our tests, the Vital 200S-P was quiet on its lower settings, making it good for bedrooms. But it can get loud when running at full power. We think this trade-off is worth it for the quick air cleaning in large spaces. If you have a smaller room, you might want to consider a less powerful model.

    LEVOIT Vital 200S-P
    • 𝐀𝐈𝐑 𝐏𝐔𝐑𝐈𝐅𝐈𝐄𝐑 𝐃𝐄𝐒𝐈𝐆𝐍𝐄𝐃 𝐅𝐎𝐑 𝐀𝐋𝐋𝐄𝐑𝐆𝐘 𝐆𝐑𝐎𝐔𝐏𝐒:The Vital 200S-P is designed specifically for allergy groups, effectively preventing allergens such as pollen, pet hair, dander, and dust from the air. Its efficient filtration system captures tiny particles, significantly improving indoor air quality and helping you and your family enjoy fresher air.
  • Coway Mighty Air Purifier

    9.5

    We highly recommend the Coway Mighty for its powerful air cleaning ability and smart features.

    Pros

    • Effective 4-stage filtration system
    • Real-time air quality monitoring
    • Energy-saving auto mode

    Cons

    • Can be noisy on highest setting
    • Takes up floor space
    • Filters need regular replacement

    We’ve been using the Coway Mighty in our home for months, and it’s become a must-have for clean air. Its compact size fits nicely in most rooms, yet it packs a punch in air cleaning power.

    The air quality indicator is a standout feature. We love seeing the LED change colors as it detects and removes pollutants. It’s oddly satisfying to watch it go from red to blue as the air clears.

    On auto mode, the Coway Mighty adjusts its fan speed based on air quality. This is great for saving energy. When the air is clean, it switches to eco mode and turns off the fan. It’s so quiet, we often forget it’s there.

    We’ve noticed a big drop in dust and pet dander since using this purifier. Allergy sufferers in our household have reported fewer symptoms. The true HEPA filter seems to catch even the tiniest particles.

    Maintenance is pretty simple. The filter replacement indicator tells us when it’s time for a change. We just wish the filters lasted a bit longer, as they can add up in cost over time.

    While it’s not the cheapest option out there, we think the Coway Mighty’s performance and features make it worth the investment. It’s a solid choice for anyone looking to breathe easier at home.

    Coway Mighty Air Purifier
    • Coway Mighty (AP-1512HH) is designed to accommodate room sizes up to 361 sq. ft (CADR: Dust 246 / Pollen 240 / Smoke 233 cb. ft. ).
  • AirDoctor 3500

    9.4

    We think the AirDoctor 3500 is a solid choice for those seeking a powerful air purifier for large spaces.

    Pros

    • Cleans air in rooms up to 1,260 sq ft
    • Ultra-fine particle filtration
    • Auto mode adjusts to air quality

    Cons

    • Pricey upfront cost
    • Replacement filters can be expensive
    • May be too large for small spaces

    We tested the AirDoctor 3500 in our home for several weeks. Its ability to clean the air in large rooms impressed us. The unit handled our open-concept living area with ease.

    The AirDoctor’s auto mode worked well. We noticed it ramping up when cooking or cleaning kicked up dust. On its lowest setting, it ran quietly enough that we barely noticed it.

    We liked the air quality sensor. The display changed colors to show air quality levels. It was neat to see it respond to things like opening windows or spraying cleaning products.

    The UltraHEPA filter claims to catch tiny particles. While we can’t verify the exact size, our allergies did seem better after using it. The carbon filter also seemed to help with cooking odors.

    One downside is the size. It’s pretty big and may not fit well in smaller rooms. The filters are also costly to replace. But for those with large spaces or serious air quality concerns, we think it’s worth considering.

    AirDoctor 3500
    • High Performance: 3-stage filtration provides another layer of protection to the air you breathe. With its UltraHEPA filter and proprietary dual-action Carbon VOC filter, the AirDoctor 3500 captures allergens, pet dander and other volatile organic chemicals like formaldehyde.
  • Hathaspace Smart Air Purifier

    We recommend this air purifier for its effective filtration and quiet operation in large spaces.

    Pros

    • Powerful 5-stage filtration system
    • Smart air quality sensor with display
    • Quiet enough for bedrooms

    Cons

    • Somewhat bulky design
    • Higher price point
    • Replacement filters needed regularly

    We tested the Hathaspace Smart Air Purifier in our living room and were impressed by its performance. The 5-in-1 filter system did a great job tackling common pollutants like dust, pet dander, and odors. We noticed a big difference in air quality, especially after cooking or when our pets were shedding.

    The smart sensor is a handy feature. We liked how it showed real-time air quality info on the display. It automatically adjusted fan speed based on air conditions, which was convenient. The touch controls were easy to use, and the included remote let us make changes from across the room.

    This purifier is pretty quiet, even on higher settings. We had no trouble sleeping with it running in our bedroom. It covers up to 1500 square feet, so it’s good for large spaces. While it’s not the cheapest option out there, we think the performance justifies the cost for most people looking to seriously improve their air quality.

    Pros

    • Covers up to 2,002 sq ft
    • Removes particles as small as 0.1 microns
    • Energy Star certified for efficiency

    Cons

    • Expensive initial investment

    • May be overkill for smaller spaces

    When we tested the NuWave OxyPure ZERO, we were impressed by its ability to clean the air in large spaces. It easily handled our 1,000 sq ft living area, cycling the air twice per hour. The unit uses a 4-stage filtration system that caught everything from dust to pet dander.

    We liked how quiet the OxyPure ZERO ran, even on higher settings. At its lowest, it was barely noticeable at 21.4 dB. The air quality sensor was responsive, adjusting the fan speed as needed. This feature gave us peace of mind, knowing it was always working to keep our air clean.

    The washable filters are a big plus. We didn’t have to worry about buying replacements often, which saves money in the long run. The app control was handy too, letting us check air quality and adjust settings from our phones. While it’s pricey upfront, we think the OxyPure ZERO is a solid choice for those with large spaces or serious air quality concerns.

  • PuroAir 240 Air Purifier

    9

    We think the PuroAir 240 is a solid choice for most people seeking cleaner air in medium to large rooms.

    Pros

    • Cleans air quickly in spaces up to 1,115 sq ft
    • Smart sensor adjusts fan speed automatically
    • Quiet operation, especially on lower settings

    We liked the auto mode feature. It took the guesswork out of choosing the right setting. The purifier ramped up when it sensed more pollutants and quieted down when the air was cleaner. At night, we used the sleep mode. It was whisper-quiet and didn’t disturb our rest.

    The touch controls were simple to use. We appreciated the child lock for homes with curious little ones. While it’s not the most stylish appliance, its black color helped it blend into the background. For its power, we found the PuroAir 240 to be a good value. It’s a solid pick for anyone wanting to breathe easier at home or in the office.

  • MORENTO Air Purifier Filter Set

    8.7

    We think this filter set is a solid choice for Coway Airmega owners looking to save money on replacements.

    Pros

    • Fits Coway models perfectly
    • Includes 2 HEPA and 8 carbon filters
    • Much cheaper than brand-name filters

    Cons

    • Carbon filters are quite thin
    • Some quality control issues reported
    • May not match OEM performance

    We recently tried out these MORENTO replacement filters in our Coway Airmega air purifier. The fit was spot-on – they slid right in without any fuss. We like that you get two HEPA filters and eight carbon pre-filters in one pack. It’s nice to have spares on hand.

    The HEPA filters seem to work well. Our air feels cleaner and we’ve noticed less dust around the house. But we’re not totally sold on the carbon filters. They’re pretty flimsy compared to the originals. We worry they might not catch odors as effectively.

    Price-wise, these are a great deal. We saved a good chunk of change compared to Coway’s own filters. For budget-conscious buyers, that’s a big plus. Just keep in mind you might be trading some performance for that lower cost. If you have serious air quality needs, sticking with OEM parts could be worth the extra expense.

  • LEVOIT Vital 100S-P Air Purifier

    8.7

    We think the LEVOIT Vital 100S-P is a solid choice for most homes, offering effective air cleaning and smart features at a reasonable price.

    Pros

    • Cleans large spaces up to 1100 sq ft
    • Smart controls via app and voice assistants
    • Washable pre-filter extends filter life

    Cons

    • App requests a lot of permissions
    • Only works with Levoit brand filters
    • May be overkill for very small rooms

    We tested the LEVOIT Vital 100S-P in our home for several weeks. It did a great job cleaning the air in our open living area. The air felt fresher, and we noticed less dust on surfaces.

    The smart features are handy. We could check air quality and adjust settings from our phones. The air quality sensor worked well, ramping up the fan when we cooked or our dog kicked up dust. At night, it automatically switched to a quiet mode.

    We like that you can wash the pre-filter. This should help the main filter last longer. The app sends reminders when it’s time to clean or replace filters. While the app is useful, it does ask for more permissions than we’d like.

    • Compact and portable design
    • Effective at removing odors

    Cons

    • Limited coverage area

    The Levoit Core Mini really impressed us with its whisper-quiet operation. Even on the highest setting, it’s barely noticeable. This makes it perfect for bedrooms or offices where you need clean air without distracting noise.

    We love how small and lightweight this unit is. It’s easy to move from room to room or take on trips. The simple controls are a breeze to use – just push a button to cycle through the three fan speeds.

    In our tests, the Core Mini did a nice job clearing the air of cooking smells and pet odors. The 3-stage filtration system catches dust, pollen, and other tiny particles too. While it works well in smaller spaces, don’t expect it to purify a large living room or open floor plan.

    Levoit Core Mini Air Purifier
    • 𝗥𝗘𝗙𝗥𝗘𝗦𝗛 & 𝗥𝗘𝗟𝗔𝗫: If you struggle with allergies, low-quality sleep, congestion, or symptoms caused by pet dander, the Levoit Core Mini-P Air Purifier is ready to help you create a comfortable space
