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.

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.

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.

Best for Style and Design

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.

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.
