1. Editor’s Pick: GermGuardian 3-in-1 Full Room Air Purifier (AC4825)
Best Overall for Price and Performance
Our nod for Editor’s Pick goes to the GermGuardian 3-in-1 Full Room Air Purifier. It offers great performance for the price, featuring a HEPA filter that captures 99.97% of dust and allergens as small as .3 microns. That includes household dust, pet dander, mold spores, and plant pollens. This product also has solid performance against common odors from pets, smoking, cooking, and wildfire smoke, thanks to a charcoal filter.
Ideal for rooms up to 167 square feet, this is a 22-inch tall air purifier with 3 different speed settings. It will filter and circulate room air over 4 times per hour, and is Energy Star Certified and CARB Compliant.
Offered with a 3-year warranty, this is a great air purifier for the average-sized household room and will do an effective job at filtering most dust and allergens. Depending on your use, a single filter may need to be replaced every 6 to 8 months, making it fairly low cost to maintain operation for years.
Another reason why it recommend this product is because it is AHAM Verified, which means its Clean Air Delivery Rate (CADR) has been independently tested. CADR ratings for this product is 118 for dust, 125 for pollen, and 108 for smoke. CADR takes into account appropriate room size and maximum clean-air delivery rate, and the higher the number, the more effective the product.
We would not recommend this air purifier for larger spaces, as it won’t be as effective. But if you’re wanting to keep a bedroom’s air nice and clean, this product should be at the top of your list.
2. Honeywell True HEPA Air Purifier (50250-S)
Best for Large Rooms to Extra Large Rooms
If you need coverage for large to extra large rooms, this Honeywell True HEPA Air Purifier fits the bill. Measuring 18 inches in diameter and 19 inches tall, this product features a patented 360-degree air intake that maximizes output efficiency in filtering. It’s also versatile, allowing you to place it in any area of the room thanks to its 360-degree coverage. Equipped with a true HEPA filter, this air purifier will capture up to 99.97% of particles as small as 0.3 microns, while an activated carbon pre-filter captures large particles and helps reduce odors. This product is also designed with Honeywell’s SurroundSeal technology, which helps minimize air leaks.
This product does require a bit more maintenance than other air purifiers, since its pre-filter needs to be replaced every 3 months. The purifier itself is equipped with a filter light to remind you when to change the filters, as well as cleaning the HEPA filter.
When used in a small room (around 80 square feet), air changes up to 23 times per hour, while in a medium room (149 square feet), it will change up to a dozen times per hour. For extra large rooms, around 390 square feet, expect air to change up to 5 times per hour.
3. Hamilton Beach Air Purifier (04384)
Best for Smaller Rooms
An extremely affordable option for smaller rooms is the Hamilton Beach Air Purifier. It offers effective performance for 140-square foot rooms, perfect for bedrooms, offices, and dens.

Also included in this air purifier is a permanent pre-filter designed to capture pet hair and large particles, along with a permanent HEPA-grade filter for capturing small particles as small as 3 microns.
Compact and quiet, maintenance on this product is average due to the 2 carbon zeolite filters that will need to be replaced from time to time. The HEPA-grade filter however can simply be vacuum cleaned.

Overall, this is a great option for smaller rooms, and its compact shape allows you to place it anywhere.

Best for Low Noise
For those with sensitive ears and have trouble sleeping with ambient noise buzzing around, this air purifier was designed for you.

While it is advertised to offer coverage up to 200 feet, this product is more effective in smaller spaces due to its CADR rating of 80 cfm.
What is especially nice about this product is that it comes with a 5-year warranty and customer support that is available 7 days a week.
5. Honeywell QuietClean Tower Air Purifier (HFD-120-Q)
Best for Low Maintenance
If you’re wanting an air purifier that won’t continually need replacement filters, adding to its lifetime cost, take a look at the Honeywell QuietClean Tower Air Purifier. This product is equipped with a filter that is washable and can be vacuumed, which means you won’t have to shell out more money every few months.

6. Coway Mighty Air Purifier (AP-1512HH)
Best for Advanced Performance if Price Doesn’t Matter
One of the more expensive options on our list comes from Coway, but it’s also one of the most effective when it comes to performance. Designed to accommodate rooms up to 361 square feet, the Coway Mighty Air Purifier has impressive CADR ratings: dust is 246, pollen is 240, and smoke is 233. If it wasn’t for the price, it would be further up on our list.
Featuring a 4-stage filtration system, this air purifier is equipped with a pre-filter, deodorization filter, true HEPA filter, and Vital Ion, capturing and reducing up to 99.97% of particles in the air. It is also effective at reducing volatile organic compounds and reducing odor. The pre-filter on this unit is washable.
Along with a timer feature that allows you to set whether this unit runs for 1, 4, 8, or 12 hours at a time, there are 3 available fan speeds if you wish to set it up manually. But what makes this unit great is that it has a built-in pollution sensor that will communicate indoor air quality in real time. On auto mode, this air purifier will optimize the speed setting based on the quality of indoor air. When it detects no pollution for 30 minutes, the fan will automatically stop and the unit will go into an Eco mode to save energy.
Naturally there is also a filter replacement indicator that checks both the pre-filter and HEPA filter to let you know when filters need changing.
7. Whirlpool Whispure
Best for Reliability/Dependability
Another more expensive product on our list is the Whirlpool Whispure, featuring a true HEPA filter that is 99.97% effective. Certified by AHAM, this unit actually impresses with 315 CADR smoke, 325 CADR dust, 401 CADR pollen, meaning it’s excellent when it comes to performance, even in large rooms. This air purifier features two filters: true HEPA and active carbon, working together to capture dust and allergens, as well as larger particles.
It offers 4 fan speeds and a Whispure Quiet System/Sleep Mode. The HEPA filters on this product should be replaced every 12 months, while the active carbon filters should be replaced every 3 months.
While it does impress with high CADR, this unit is a bit on the expensive side and doesn’t offer any sort of advanced features. In fact, it doesn’t even have a programmable timer, with just an automatic on/off after 8 hours. Its sound level is also a bit on the high side, even in Sleep Mode, at 43-44 dbA.
If you’re needing an air purifier that’s extremely effective in rooms up to 500 square feet however, this would be our suggestion. Just keep in mind that filter changes can get costly. Contributing to its reliability and dependability however, is a 5-year warranty.
8. LEVOIT Air Purifier (LV-PUR131)
Best for Style and Design
We get it—for some people, air purifiers can be unsightly, especially if you’ve decorated a room with a specific theme. We find LEVOIT’s Air Purifier to be one of the most stylish units out on the market, with an overall simple and clean design. This product is 100% ozone free, which means it does not use UV or ions that produce trace amounts of measurable ozone, a harmful air pollutant.
Featuring a 3-stage filtration system, the LEVOIT Air Purifier has a pre-filter, true HEPA filter, and an activated carbon filter, removing 99.97% of dust, pollen, smoke, odor, mold spores, and pet dander. Like other products on this list with a similar filtration system, this unit will filter particles as small as 0.3 microns and larger air pollution of PM 2.5.
It’s a more advanced unit, powered by a smart auto mode that checks the surrounding air quality and automatically suggests a fan speed. A sleep mode will set the purifier to its lowest setting, allowing you to sleep in relative peace and quiet. It’s CADR rated at 135+ and offers coverage for rooms up to 322 square feet.
On average, the filter in this unit needs to be replaced every 6 months, while the air filter may need to be replaced sooner or later depending on use. This purifier is Energy Star certified, CARB, FCC, and CE approved. One thing to keep in mind is that LEVOIT offers a 1-year buyer assurance, with an option to extend it by 1 more year, along with lifetime support. It’s not as attractive as the 5-year warranty that some companies offer with their products.
