HPA300 HEPA Replacement Filters for Honeywell Air Purifier Filter Replacement R True Filter 3 Pack HRF-R3 Carbon Pre Filters 4 Pack Compatible with Honeywell HPA300, HPA304, HPA5300, HPA 8350

I am always concerned when not using the name brand for replacements like these. However the name brand is so expensive so I thought I would try them and see. Works great and is as functional as the name brand. No prolems and works the same.

Liked the price and great fit

The prefilter and filter package was a good value for the money.

These filters are noticeably too small for the Honeywell filters, which is a shame. In order for HEPA level quality filters to be effective, you have to have a good, snug fit around the filter. If you dont, air just goes around the filter, which is exactly what happens with these.

Quick easy install! My only complaint is that the black filters are folded in half in the box. When in installing it, because of the shape, the black filter does not lie flat and it slides out of the plastic holders in the corners.

Did the job as expected.

Perfect fit. Noise of machine immediately got less than before changing the old one out! Definitely cuts down on dust… I haven’t changed mine out in at least a year so that’s why they got so bad but still great work!

Pre-filters are nothing like the actual honeywell ones. They are extremely thin and almost hard or stiff feeling. Also all the filters are slightly smaller than the actual honeywell ones, too the point that the pre-filters dont even stay in the little clips on the machine. You have to put them in with the machine laying down or put it in and close lid super quick before the filter falls out.

The only downside is you need to cut to fit your own machine, which leaves you with wasted scraps. Otherwise great
