Breathe Naturally - HPA200 HEPA Replacement Filters - Honeywell Replacement Filters for Premium Air Purification -Ideal HPA200 Filter Replacement for Home & Office Use(2 pack HEPA Replacement Filter)

These are too small lengthwise, and they're press-fit into the air purifier. I had to cut strips of cardboard out of the box they came in to make shims. Both filters stay in place only with the cardboard shims- two stacked for each filter.I'm running an HPA300 with two of these and one Honeywell OEM filter. So far the flow seems the same as OEM as per the dust on the carbon prefilter. I'll update this review if they perform differently over the next year.Minus two stars for bad QA on the size.

I have an HPA 200, which uses two HEPA filters. These replacements fit perfectly. When I set them side-by-side with the Honeywell-branded filters, I can't see any difference in length, width, thickness, or density. (These were purchased January 2021.)

These are a great value and work well with our Hewlett Packard air purifiers.

we have 10 giant dogs so tough challengeworks OKno complaints

These aftermarket filters look, fit and work just like the more expensive Honeywell filters. They are a lot cheaper. I will never go back. There is no size difference or anything. If your air cleaner uses this size make the switch.

The filters are good. I was comcerned about a smell, but i didnt detect anything. And I have the air purifier in my room so I would notice anything pretty quickly. I’ll probably use them again

Good quality aftermarket product

Second time I have bought them... can't say enough about how great they are!..my husband still smokes.. I can't smell it when I came home!!.…a great bargain compared to the company made ones.. good for about 6 months for us!!.. I will keep buying them!
