HONEYWELL True HEPA Allergen Remover, 465 sq. Ft, HPA300

Product Information

The Honeywell HPA5300 is a high efficiency particulate air (HEPA) air purifier, which means it can remove up to 99. Most Honeywell Air Purifiers feature a “Filter Check/Reset” indicator that will alert you whenever it's time to change the filter.

At its lowest setting, it’s very quiet – albeit not as quiet as the Blueair – and there’s a night mode that turns off all its lights until daybreak. Its features include a clear-view front panel made of plexiglass, a gloved hand access on the right, which allows us to manipulate the air purifiers, a particle counter holder for our control device, two fans that ensure proper mixing of the air and smoke inside the chamber, vent ports that ensure there is a small amount of fresh air at all times, an ignition port to light up the smoke bombs from outside the rig, and an exhaust port that removes the remaining smoke safely from the chamber and the building after each test. This portable air purifier uses an activated carbon pre-filter that helps capture large airborne particles and reduce odors and VOCs. Sports a color-coded air quality indicator, eco-mode, filter alerts and has an ionizer option that enhances bacteria and virus removal. It struggled in our particle removal test, and was the loudest of the small-sized air purifiers we tested.

The Honeywell HPA100 and the Dyson Pure Hot + Cool HP01 both use HEPA filtration systems but are otherwise very different machines.

The numbering system for the purifiers and filters is confusing, so I bought from Honeywell directly to be sure I had the right filters.That includes a testing room that has over double the footprint of AHAM's testing rooms, along with nine sensors placed around the space (versus AHAM's single sensor). It’s also an extremely efficient air purifier, achieving best-in-class performance with the second lowest power draw of any unit we tested. It’s designed to sit on your desk or bedside table like a turbocharged house plant,” says Matt Thomas of John Lewis. We just got the cutest baby kitten, it’s fall allergy season, and I live in God’s country, Lake Tahoe. You can see the results for yourself in the graph below -- each unit we tested clocked in at around 35 decibels at its low setting, but we saw greater differentiation at medium and high settings.
