Honeywell HEPA Air Purifier Filter Kit – Includes 3 HEPA R Replacement Filters and 4 A Carbon Pre-Cut Pre-Filters – Airborne Allergen Air Filter Targets Wildfire/Smoke, Pollen, Pet Dander, and Dust

Quality product, great machine.

Product is easy to install, functions as described. Great brand name. We would give five stars if the price-point were better.

For this to be one of the top rated air purifiers on CR it sure is hard to find this item for the HPA300. Much easier to find the kits for the smaller 2 filter model. Anyway, considering the price of buying the whole unit, the replacement filters seem very overpriced at 80 bucks. The unit does work well. I’ve been using these Honeywell’s going back over 20 years. They were cylindrical back then. I actually liked that design better and the hepa element would last 3 years vs 1 year on these. Much more cost effective. It seems now that everything made has built in warning lights and timers telling us it’s time to spend more money on filters! Fridge is the same. Same with my thermostat. Seems a bit wasteful and a money grab by manufacturers.

Pricey but worth it

My air purifier

People that buys air filter are either wanting to live healthier or have respiratory issues. So when the air filter smells like gasoline ... it defeats the purpose of improving air quality. Some other review seems to be running into the same issue. I was hoping I would get a different batch... but nope, same batch. I aired it out by putting in front of a fan x 48hr and under the sun for a few hours. The smell becomes undetectable after that, but do not know if it is still off gassing. It does not put the mind at ease when using it.

can save a lot of money by going aftermarket, if your changing filters as recommended go with the aftermarket stuff and save money

These work very well in my air purifier!

These filters and pre-filters for my air purifier perfectly, like they came with it. If anything I think they might fit more snug than the original. Very happy with this replacement purchase and intend to buy more next year.

R filters for great and easy to install. A filters were oversized and needed to be cut down (they still work) just confused since thats the size my product needs.
