Bottom lineThe Honeywell True HEPA Whole Room Air Purifier with Allergen Removal, HPA300C quickly and effectively cleans the air in large rooms up to 465 square feet—the greatest coverage of any of the air purifiers we tested. It offers modes for general air purification, allergens and germs (ideal for cold and flu season), plus you can kick it up to Turbo mode when needed. While it doesn’t have the bells and whistles that you’ll see in some other models, for families who want to set it and forget it, this air purifier is a great option.
From allergens and odours to pet dander and dust, any number of everyday factors can impact the quality of air in your home—and that can have an impact on your health. An air purifier can help remove particles like these from indoor air, but some are definitely better than others, and you need to make sure the one you buy is an appropriate size for the room it'll be placed in. One of our top picks for large spaces is the Honeywell True HEPA Whole Room Air Purifier with Allergen Remover (HPA300C), which is designed to filter particles as small as 0.3 microns in rooms up to 465 square feet. It features a true HEPA filter to trap airborne particles like dust, pet dander, mould spores and some bacteria and viruses, as well as an activated carbon pre-filter to absorb odours and volatile organic compounds. The Honeywell HPA300C has three modes—general, germ and allergen—as well as a Turbo Clean setting if you need to clear the air quickly.
In order to test air cleaning effectiveness, editors placed the Honeywell True HEPA Whole Room Air Purifier in an air-tight 8- x 8- x 4-foot space along with an ultra-fine particle counter and then sprayed dry shampoo into the space for five seconds. The Honeywell air purifier made quick work of cleaning the air, bringing the particulate levels down to under 100 particles per cubic centimetre (well below what’s considered clean air) within just five minutes. Editors in the Today’s Parent Approved lab also looked at the clean air delivery rates, a score that indicates how quickly a device filters the air; this independent testing is carried out through the Association of Home Appliance Manufacturers. According to the CADR scores, it does a good job of filtering the three particulates tested (tobacco smoke, dust and pollen) in rooms up to 465 square feet—a considerably larger space than many room air cleaner units on the market.
Parents who tested the air purifier at home had it running in various rooms, including a basement, living room, nursery and bedroom. The majority of parents said the Honeywell True HEPA Whole Room Air Purifier with Allergen Remover effectively cleaned the air and most said it was efficient in the various modes. One pregnant mom told us she noticed less sinus congestion at night when using the air purifier, which has helped her sleep better, and another was impressed with how well it performed in her little one's nursery.
Our testers loved that this air purifier has modes rather than fan speed settings. While this air purifier doesn't have a nighttime mode (which typically hushes the fan and dims lights), its running volume is fairly quiet on non-Turbo modes, you can dim or turn off the lights with the press of a button and the unit doesn't beep as settings are changed, which means it's not going to accidentally wake up sleeping little one.
Whether you're in those sleep-deprived early days of parenthood or juggling work, family time and all your kids' play-dates and activities, easy-to-use products are a must. Testers loved the simple set-up of the Honeywell True HEPA Whole Room Air Purifier with Allergen Remover, and both editors and parent testers were fans of its intuitive control panel: tap controls for the modes, timer, light dimmer and filter checks are clearly labelled either with text or universal icons, and you can quickly make adjustments. While there isn't a dedicated on/off button—you have to cycle through the modes—it does feature a timer, so you can set the air purifier to automatically turn off after two, four or eight hours. Two notable features that you won't find on this model are an air quality display (so you can tell if you should keep the unit running or turn it off) and app connectivity to control the air purifier through a smartphone.
When it's time to replace the filters, a reminder will light up on the top panel. The activated carbon pre-filter typically needs to be replaced every three months, while the three HEPA filters generally get replaced yearly. Removing the front cover to replace the filters is a breeze: a light press in releases a latch on either side and then you just pull the cover out and up. Placing the filters is also fairly simple, though it's a bit finicky to tuck the edges of the carbon rep-filter into the tabs that help keep it in place. You'll also want to replace the front cover with a bit of a light touch, as the latching mechanism can break if you try to force it closed. If you want an air purifier you can move from room to room, this one is quite lightweight and it has inset handles on either side, but it's among the larger models.
If you’re looking for a simple air purifier that skips the bells and whistles and gets straight to the business of cleaning air, the Honeywell True HEPA Whole Room Air Purifier with Allergen Remover, HPA300C is a great option. Ideal for large spaces, it's very user-friendly and offers modes instead of speeds, which our testers loved. The majority of our testers gave it good or very good ratings for ease of use and quality. While their opinions on value ranged more widely, our editors found that this air purifier's effectiveness and efficiency, suitability for large rooms (it covers the most square footage of any of the air purifiers we tested) and five-year warranty pack a lot of value into a model that has a mid-range price point.
