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

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.

I loved the fact that the black filter is pre cut

Fitment is not perfect. Has a glue smell after installation. Doesnt have nearly the filter material as oem.

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.

Fits perfect and to have extra on hand

The micro-filters arent a tight fit and fall out unless you turn the fan on. The pre-filters are much thinner than other brands Ive purchased.

The HEPA filters fit perfectly, but you have to cut to size the pre-filter.

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!

I would have given 5 stars but the fact that I have to ✂ (cut) the filter to size that wasnt included in the description.

Eaay to use
