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 much larger then filters that come with air purifier. You get a lot of them. But only 3 filters

These are working awesome! However the charcoal filters then sent are HUGE. idk if it’s made to cut down or what. I cut it with scissors. Makes a mess but whatever. Saving money with these anyway.

As describe. Great fir money

This unit is the best I’ve ever bought. It really does it job

Easy to navigate website led me to the right filters for our air cleaner. They came quickly and they fit perfectly into our air cleaner/purifier. We are back in business breathing HEPA cleaned air.

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.

Easy to install.

Well I didn’t get what I ordered missing a r filter and I need 3 to run

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.
