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

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

The white filters were loose. The black filter added in made a high pitched air tone. Unit is in our bedroom and there was no way I was sleeping with this. Will not buy again. Dont know what to do with the black filters. Tried to save some money. Damn Honeywell ones are way too expensive.

What I needed

Easy install and it works just as effectively as the name brand product. Definitely will buy again.

Our air purifier was clearly not working as well as it had been and had a slight odor. I had been vacuuming the filters. Decided to try the new filters and see if it worked better and IT DID! Great way to get your air purifier running more efficiently. I will not ever attempt to vacuum the filter again and will be just replacing them with another kit when he time comes.

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

Fit nicely into my unit. Price was somewhat lower than other brands.

Was less cost than honeywell filters and they work just as good.

So the mini rectangle white filters were good but instead of the rectangle black filters, horrible. They sent like a big folded over sheet and I have to cut it down to size. Either someone just packed it wrong or something.
