Clean air is essential for our health, especially in homes where allergens, dust, and pollutants can accumulate. Air purifiers help remove these unwanted particles from the air we breathe, creating a healthier indoor environment. These devices are particularly valuable for people with allergies, asthma, or other respiratory conditions.
Air purifiers come in various types, using different technologies to clean the air. Some use HEPA filters to trap particles, while others might use activated carbon filters for odors or UV light to kill germs. The best air purifiers combine multiple filtration methods to address different air quality issues effectively.
When shopping for an air purifier, pay attention to the Clean Air Delivery Rate (CADR), which indicates how quickly it filters the air. Room size coverage, filter replacement costs, and noise levels are also important factors to consider. Energy efficiency matters too, especially if you plan to run your purifier continuously.
We tested fifteen popular air purifiers over several weeks to find the ones that effectively clean indoor air while being easy to use and maintain. Our testing focused on performance, noise levels, and overall value to identify truly effective options for various needs and spaces.

We’ve tested dozens of air purifiers to find the top models for every need and budget. Our picks remove dust, pollen, smoke, and other harmful particles from your indoor air. These devices can help reduce allergy symptoms and create a cleaner, healthier home environment.
LEVOIT Core 300-P Air Purifier
The LEVOIT Core 300-P is worth every penny for anyone seeking cleaner air thanks to its powerful performance, whisper-quiet operation, and versatile filtration options.
Pros
- Extremely quiet at just 24dB in Sleep Mode
- Powerful coverage for spaces up to 1095 sq ft
- Multiple specialized filter options for different needs
Cons
- Replacement filters add to long-term cost
- Base model only includes standard filter
- Not smartphone compatible
We’ve been testing the LEVOIT Core 300-P in our home for several weeks, and the difference in air quality is remarkable. This compact purifier packs serious cleaning power with its 56W high-torque motor. The sleek white design blends seamlessly with our decor, while its 8.7″ x 8.7″ footprint doesn’t take up much space despite its impressive capabilities.
The Core 300-P shines brightest in its quiet operation. At night, we switch to Sleep Mode, and at just 24dB, we can barely tell it’s running. This feature alone makes it ideal for bedrooms and nurseries. We also appreciate the option to turn off the display light completely for truly undisturbed sleep.
What sets this purifier apart are the specialized filter options. While it comes with a standard 3-in-1 filter that works well for general use, we tried the Pet Allergy filter in our cat’s favorite room and noticed a significant reduction in dander and litter box odors. The Smoke Remover filter also performed impressively when we accidentally burned dinner. With a 99.97% filtration efficiency for particles as small as 0.1 microns, we’ve noticed fewer allergy symptoms and less dust throughout our home.
Air quality isn’t something you can see, but you can definitely feel the difference. Our morning congestion has improved, and there’s noticeably less dust on surfaces throughout the week. For under $100, the LEVOIT Core 300-P delivers exceptional value for anyone concerned about indoor air quality.
LEVOIT Vital 200S-P Air Purifier
The LEVOIT Vital 200S-P is worth buying for allergy sufferers who need powerful air purification in large spaces with its smart features and excellent filtration system.
Pros
- Covers up to 1800 sq ft with strong filtration performance
- Smart controls via app with scheduling options
- Washable pre-filter reduces maintenance costs
Cons
- Noisy at highest settings
- Bulky size takes up floor space
- Replacement filters can be expensive
We recently tested the LEVOIT Vital 200S-P in our home, and it quickly became clear why it has such high ratings. The air purifier made a noticeable difference in just a few hours. Our team member with cat allergies reported breathing easier after we set it up in the living room where two cats usually hang out.
The unit’s design includes both traditional and U-shaped air inlets that trap pet hair effectively. This feature stood out during our testing period as it prevented the clogging issues we’ve seen with other purifiers. The washable pre-filter is also a money-saver – we simply rinsed it under water when it got dusty, extending the life of the main filter.
Smart features make this purifier especially user-friendly. We connected it to our WiFi through the VeSync app and created different schedules for day and night use. The auto mode works well, adjusting fan speed based on air quality. At night, it switches to sleep mode which runs quieter but still filters effectively. The display automatically dims in dark rooms, which we appreciated.
The coverage area is impressive. In our open-concept living and dining area (about 900 sq ft), it cleaned the air quickly. LEVOIT claims it can handle spaces up to 1800 sq ft, cycling all the air once per hour. While we didn’t test it in a space that large, it certainly had no trouble with our medium-sized rooms.
One thing to note – this purifier isn’t small. At nearly 20 inches tall and over 13 pounds, it demands floor space. However, the white design helps it blend with most decor. For anyone dealing with allergies, pets, or just wanting cleaner air, this LEVOIT model delivers excellent performance for its price range.
Shark NeverChange Air Purifier MAX
The Shark NeverChange Air Purifier MAX offers exceptional value with its no-replacement filter design that saves money while effectively cleaning large spaces.

- Features odor neutralizing technology with fresh scent
Cons
- Higher upfront cost than basic models
- Larger size takes up more floor space
- Fan can be noisy at maximum settings
We tested the Shark NeverChange Air Purifier MAX in our home for several weeks and were impressed by its powerful performance. The most striking feature is the filter that doesn’t need replacement for up to 5 years. This design saved us from the usual hassle of buying new filters every few months.
The air quality sensor works well, automatically adjusting the fan speed when it detects particles. We placed it between our kitchen and living room, and it quickly cleared cooking smells and dust. The real-time display shows air quality changes, which helped us see how effectively it was working throughout the day.
Cleaning is simple with the washable Debris Defense filter. We removed it after two weeks of use and were surprised by how much dust it had collected. A quick rinse and it was ready to go again. The unit covers a large area, making it perfect for open floor plans or multiple connected rooms.
The odor neutralizing feature works better than expected. When our dog came in from the rain, the purifier kicked into high gear and eliminated the wet dog smell within minutes. The fresh scent release isn’t overpowering – just a light, clean fragrance that makes the home feel fresher.
LEVOIT Core Mini-P Air Purifier
We believe this compact Levoit air purifier is worth buying for anyone seeking cleaner air in small spaces without breaking the bank.
Pros
- Extremely quiet operation (as low as 25dB)
- Compact size fits on desks and nightstands
- Includes aromatherapy function
Cons
- Best for smaller rooms (up to 337 sq ft)
- Requires regular filter replacements
- Power adapter stored inside can be tricky to find
The Levoit Core Mini-P sits quietly on our desk, doing its job without drawing attention. We barely notice it running on the lowest setting while we work. Its sleek white design blends with most decor, and the small footprint (just 6.5″ × 6.5″) doesn’t hog precious space.
After using it for a week, we noticed fewer dust particles floating in the sunlight coming through our windows. The 3-in-1 filter system really seems to work. Pet owners will appreciate how it catches dander and hair before they spread throughout the room. The built-in aromatherapy feature is a nice bonus – adding a few drops of essential oil to the sponge creates a pleasant environment.
At night, we love the auto-off display feature. No annoying lights to disturb sleep! The highest fan setting can be a bit noisy, but the lower settings strike a perfect balance between air cleaning and quiet operation. For apartments, dorm rooms, or offices where space is limited, this little purifier delivers impressive results without commanding attention or using much electricity (just 7 watts).
LEVOIT Vital 100S-P Air Purifier
The LEVOIT Vital 100S-P is worth buying for its excellent air cleaning performance, smart features, and pet-friendly design that effectively removes allergens and odors.
Pros

- Smart app control and scheduling options for convenience
- Washable pre-filter saves money and extends filter life
Cons
- Only compatible with Levoit’s original filters
- May be overkill for very small rooms
- Display lights can be bright until auto-dimming activates
We recently tested the LEVOIT Vital 100S-P in our home, and the difference was noticeable within hours. The air felt fresher and cleaner almost immediately. This compact unit handles spaces up to 1110 square feet, making it perfect for living rooms, bedrooms, or open-concept areas.
The Pet Mode feature really impressed us. It effectively captured pet hair and dander that was floating in the air. The U-shaped inlet design seems to pull in more fur than other purifiers we’ve tried. We could actually see the difference when we checked the pre-filter after a week of use in a home with two shedding dogs.
Smart features make this purifier especially convenient. We downloaded the VeSync app and could control settings from anywhere, check air quality in real-time, and set custom schedules. The HEPA Sleep Mode automatically dims the display and quiets operation when the room darkens. This thoughtful touch ensures peaceful sleep without bright lights or disruptive noise.
The washable pre-filter is a money-saving feature we love. Just rinse it clean instead of constantly buying replacements. Behind that, the activated carbon filter does an excellent job with pet odors and cooking smells. Our home smelled noticeably fresher after running the purifier during cooking sessions.
For households with allergy sufferers or pet owners looking for cleaner air, this LEVOIT model delivers excellent performance in a compact, smart package. The combination of powerful filtration, quiet operation, and convenient features makes it a standout choice for improving indoor air quality.
Coway Mighty Air Purifier
The Coway Mighty air purifier delivers exceptional air cleaning power in a compact size, making it a smart purchase for anyone wanting cleaner air in medium-sized rooms.
Pros
- Four-stage filtration system captures 99.97% of tiny particles
- Smart air quality indicator with color-coded LED display
- Energy-saving Eco mode turns off fan when air is clean
Cons
- Higher fan speeds can be somewhat noisy
- Replacement filters add to long-term cost

We tested the Coway Mighty in a dusty apartment with two cats, and the results were impressive. Within 30 minutes, we noticed a significant difference in air quality. The unit pulled in visible dust particles, and the air felt fresher and cleaner. The air quality indicator shifted from red to blue as the purifier worked, giving us real-time feedback on our indoor air.
The compact design makes this purifier easy to place in different rooms. It stands at just over 18 inches tall with a modern white finish that blends well with most decor. We appreciate the touch controls which are responsive and intuitive. The fan has three manual speed settings plus an auto mode that adjusts based on detected air quality.
At night, we enjoy the timer function that lets us set the purifier to run for 1, 4, or 8 hours before shutting off. The lowest fan setting is quiet enough for light sleepers. When no pollution is detected for 30 minutes, the Eco mode kicks in to save energy, which is both environmentally friendly and cost-effective. For a medium-sized room purifier, we find the Coway Mighty offers excellent value with its combination of effective filtration and smart features.
Blueair Pure 211i+ Max Air Purifier

We tested the Blueair Pure 211i+ Max in our living room and were blown away by how quickly it improved the air quality. Within minutes of turning it on, we noticed the air felt fresher. The air quality indicator changed from yellow to blue, showing us in real-time how it was removing particles from our home.
The smart features really set this purifier apart. We connected it to our phones through the Blueair app and could control settings from anywhere. The Clean Air ETA feature tells you exactly how long until your room’s air will be clean. We especially liked the Welcome Home feature, which automatically turns on the purifier when you’re approaching your house.
At night, we appreciated how quiet this machine runs. On the lowest setting, it’s barely audible at 23 dB. We could sleep without distraction while it continued cleaning. The HEPASilent technology makes it much quieter than other purifiers we’ve tried with similar cleaning power.
The washable fabric pre-filter is a nice touch that extends the life of the main filter. Ours came in Stockholm Fog color, but you can buy other colors separately. When the main filter eventually needs replacement, the app gives an accurate estimate based on actual usage rather than just time.
For homes with pets, allergies, or cooking odors, this purifier handles it all. We cooked fish for dinner and were impressed by how quickly the carbon filter eliminated the lingering smell. The powerful fan circulates air efficiently through the entire room.
Winix 5500-2 Air Purifier
The Winix 5500-2 is worth buying for its powerful three-stage filtration system that effectively cleans air in medium to large rooms while offering smart features at a reasonable price.

The PlasmaWave technology sets this unit apart from other purifiers we’ve used. It breaks down odors and pollutants at a molecular level without producing harmful ozone. We noticed fewer allergy symptoms within days of running it in our home. The purifier covers spaces up to 360 square feet, making it ideal for bedrooms, living rooms, or medium-sized open areas.
Smart sensors on the Winix detected changes in air quality immediately. When we cooked with strong spices or burned toast, the fan speed increased automatically. At night, the sleep mode kept noise levels down to a whisper-quiet 27.8 dB. The unit has a solid build quality with a clean design that fits well with most home décor. Overall, this air purifier offers excellent value for anyone looking to improve their indoor air quality.
GermGuardian True HEPA Air Purifier
This air purifier is worth buying for its powerful HEPA filtration that effectively removes allergens, pet dander, and odors while offering good coverage for medium to large rooms.
Pros
- Captures 99.97% of particles as small as 0.1 microns
- Includes UV-C light technology for added germ reduction
- Works well in spaces up to 743 square feet
Cons
- Fan can be noisy on higher settings
- Replacement filters are somewhat expensive

We recently tested the GermGuardian air purifier in our office and were impressed by its performance. The True HEPA filter pulled dust and allergens from the air quickly. Within just a day of use, we noticed less dust collecting on surfaces and fewer sneezes from our allergy-prone team members.
The three-speed settings give good flexibility. On the lowest setting, it runs quietly enough for nighttime use. Higher speeds make more noise but clean the air faster. We found the medium setting works best for daily use, balancing noise and cleaning power well.
What sets this unit apart is the UV-C light technology. It adds another layer of protection against germs that simple filters miss. The activated carbon filter also does a great job with odors. We placed it near the kitchen, and cooking smells disappeared much faster than before.
For larger rooms, this GermGuardian performs admirably. It cycles all the air in a 743 square foot room once per hour, which is perfect for living rooms or open spaces. In smaller rooms like bedrooms (around 150 square feet), it refreshes the air nearly five times every hour. The slim tower design helps it fit in corners without being too obtrusive.
Buying Guide
Choosing an air purifier can be tough with so many options available. We’ve put together this guide to help you find the right one for your needs.
Room Size
The air purifier you choose must match your room size. Air purifiers are rated by their coverage area in square feet.
| Room Size | Recommended CADR |
|---|---|
| Small (up to 200 sq ft) | 65-100 |
| Medium (200-400 sq ft) | 100-200 |
| Large (400+ sq ft) | 200+ |
Clean Air Delivery Rate (CADR)
CADR tells you how quickly an air purifier can filter air. Higher numbers mean faster cleaning.
Look for CADR ratings for dust, pollen, and smoke. The best air purifiers have high ratings in all three categories.
Filter Types
HEPA Filters capture 99.97% of particles as small as 0.3 microns. They’re the gold standard for air purification.
Activated Carbon Filters remove odors, gases, and VOCs. They’re great for kitchens or homes with pets.
Pre-filters catch larger particles like dust and hair before they reach the main filter.
Noise Levels
Air purifiers can be noisy at high speeds. We recommend checking the decibel (dB) rating:
- Below 50 dB: Quiet enough for bedrooms
- 50-60 dB: Noticeable but not disruptive
- Above 60 dB: May interfere with conversations or sleep
Energy Efficiency
Look for ENERGY STAR certified models. They use about 40% less energy than standard models.
Additional Features
Air Quality Sensors detect pollutants and adjust settings automatically.
Timer Functions let you set when the purifier runs.
Filter Replacement Indicators remind you when it’s time for a new filter.
Frequently Asked Questions
Air purifiers can solve many indoor air quality problems. Let’s look at the most common questions people have when choosing the right one for their needs.
What are the top-rated air purifiers for alleviating allergies?
For allergy sufferers, we recommend the Blueair Blue Pure 211+. It captures 99.97% of airborne allergens including pollen, dust mites, and pet dander.
The Honeywell HPA300 also performs excellently against allergens. Its True HEPA filter traps particles as small as 0.3 microns, making it ideal for severe allergy seasons.
Coway AP-1512HH Mighty is another top choice with its 4-stage filtration system. This compact unit works well in medium-sized rooms and runs quietly on its lower settings.
How effective are air purifiers in removing dust from indoor environments?
Air purifiers with HEPA filters remove up to 99.97% of dust particles from the air. This significantly reduces visible dust on surfaces and improves air quality.
For best results, we recommend placing the purifier in high-traffic areas. Models like the Levoit Core 300 are particularly effective at dust removal in spaces up to 219 square feet.
Regular filter replacement is crucial for maintaining dust-removal efficiency. Most quality purifiers have indicator lights that tell you when it’s time to change filters.
Which air purifier models are best suited for use in bedrooms?
The Coway Airmega AP-1512HH works perfectly in bedrooms. Its sleep mode turns off display lights and runs almost silently at just 24 decibels.
We also recommend the Blueair Blue Pure 411. It’s compact, energy-efficient, and produces white noise that many people find helps them sleep better.
For larger bedrooms, the Winix 5500-2 offers excellent coverage and includes a sleep mode that automatically adjusts fan speed based on air quality during the night.
Can air purifiers significantly reduce the presence of mold in the home?
Yes, air purifiers with HEPA filters can capture mold spores floating in the air. The GermGuardian AC4825E has both HEPA filtration and UV-C light technology that helps kill airborne mold.
However, air purifiers cannot remove mold growing on surfaces. They work best as part of a comprehensive approach to mold control that includes fixing moisture problems.
For homes with serious mold concerns, we recommend the Austin Air HealthMate. Its activated carbon filter helps remove both mold spores and the musty odors associated with mold growth.
What features should be considered when choosing an air purifier for pet owners?
Pet owners should look for air purifiers with strong odor control. Models with activated carbon filters, like the Winix 5500-2, excel at removing pet odors.
We also recommend looking for washable pre-filters that can catch pet hair before it clogs the main filter. This feature saves money and extends the life of expensive HEPA filters.
The Rabbit Air MinusA2 is our top choice for pet owners. It includes a customizable filter option specifically designed for homes with pets.
Are there air purifiers that are particularly good at eliminating bad odors?
The Winix 5500-2 with its carbon filter excels at removing cooking odors, pet smells, and smoke. It uses plasma technology that breaks down odor molecules rather than just trapping them.
For severe odor problems, we recommend the Austin Air HealthMate. Its 15 pounds of activated carbon make it one of the most effective purifiers for eliminating persistent smells.
The Coway Airmega 400 also performs well against odors. Its dual carbon filters provide excellent coverage for large spaces up to 1,560 square feet.
