Durabasics 3 HEPA Filter Set for HPA300 Honeywell Air Purifier Filters & Honeywell HPA300 - For Honeywell Air Purifier Filter Replacement HPA300 - Replacements for Honeywell Filter R & HPA300 Filter

You should see the dust that this system filters out of the air. We noticed that we were coughing and sneezing but didn’t know why. I would recommend this Honeywell air filter.

I like knowing that the air in the house is being filtered to keep down as much dust, animal allergies my husband has and much more.

quick delivery work as designed

Good quality

I saw that the price I paid was more than other dealers but that would not have bothered me if the order had arrived in a timely manner. No problems I am aware of with the filters, fit well. So far, so good.

These filters fit right into the air purifier.

This works just as good as the expensive brand. They fit just like the original filters and work just as well.

They fit slightly tighter than other brands but were still easy to pop into place. I’ll likely buy these again once it’s time to replace them.

Wish they didnt fold the pre-filters as much as they do. But they are nice and thick, like the original one that came with the unit (and unlike the refills I have gotten from Honeywell) The HEPPA filters seem to fit tighter than the Honeywell filters, but that could just be because they are new, will have to see how they are after sitting in there for a year.

Very strange smell on the last set of the HEPA filters emanating from unit. Checked carbon filter and fan blades. All clean. Then ran the unit without filters to see if it was electrical. Unit produced no smell. Finally did a direct nose sniff of the HEPA filter and found it to be the culprit. Since these were installed just 2 weeks ago, and never had an odor problem prior, the conclusion is that somewhere in the production line, even though these come sealed in plastic, there was an introduction of a foreign element in the manufacturing. Unit is used in living room and to my knowledge here was no incident of contamination from a chemical or toxic source on my part. I am now hesitant to order these again from the same company or brand.
