DEKIRU Carbon Activated Filter Precut for HPA300 Prefilter Compatible with Honeywell Air Purifier Filter, Fit for Easy Installation Advanced Filters (6 Pack)

Fit great thank you

like the thickness

Fits perfect

The wildfire smoke is horrible this year, our air quality is rated as Hazardous most days or very hazardous some days.Ordered this pack of six, removed the HEPA filter out of my air filter and just stacked all six of these in there and turned it on to help neutralize the campfire smell in the house. You also want to be running an actual hepa filter as well to filter the ash particles which i am but a hepa filter itself i don't think does a good job of eliminating odors. There's some really expensive hepa cartridges that specifically address odors but those are super expensive cartridges. These were a way better value, had to trim them to fit though but otherwise happy with the results.

I have a litter robot 4 and the replacement carbon filters are very expensive - $30 for six. I knew I could buy these sheets & cut enough to come out with quite a savings & sure enough I did. These sheets are a bit thinner albeit they are denser - Even if I end up doubling the filters I will still come out on quite the winning side. I haven't cut them all out, but based on the ones that I have cut out, I have more than doubled the quantity if I had bought the brand name filters. Based on the ones I have ready to go, it will be a year before I will need to purchase filters again - and I have three cats and empty the drawer bags twice a week so maybe that will help someone project how my use compares to theirs.
