BIODEFENSOR HPA300 Replacement Filter Complete Pack - 3 HEPA and 4 Activated Carbon Pre-Cut Pre Filters - Non-Toxic - Compatible with Honeywell Air Purifiers HPA 300, 300C, 304, 8350B, 5300B

Great deal over the cost of the original. Works the same and way cheaper. Some people are reporting a chemical smell from the filters . I did not smell that .

As far as i can tell these are the same as the originals, so if they were any good, I’d suspect these are also. Didn’t give 5 star all the way because I honestly don’t know if they are long lasting. Only had them two weeks now, but i feel comfortable with them. Reckon time will tell.

Having 2 large dogs that shed a ton seemingly year-round, I go through filters a lot faster than normal. I purchased this to save a few bucks over the stock filter replacements. They work just as well and the extra prefilters made it that much better of a value. I really can't tell the difference between these and the originals.Would definitely recommend, and will purchase again soon.

I use these as replacement filters in my Honeywell air purifier, and they do their job well in a household of allergies and pets.

We've been using these filters for quite a while. They fit well and are good filters for the price.

I ordered the wrong size which is 100% my fault but they actually still work great with my purifier so that is awesome. Came quick, good packaging and im very happy.

Great replacement filters for my air purifier. Reasonable price and quick shipping from the company.

Affordable, easy to install, seems same quality as Honeywell filters provided with air purifier.

As advertised
