6-Pack Prefilter A for Honeywell HPA200 Series Air Purifiers, HRF-A200 Carbon Pre Filter, Thickened to 1/4 Inch

These are easy to use since precut. They were a great price. Will buy again

These are so much better than having to cut the pre-filters like I did before. I have dusty birds so a pre-filter is a must. I shake them out regularly and they last a long time.

for humidifier, works good.

I bought this product multiple times. It came in a professional looking grey box. They fit perfectly with the Honeywell 200 model I have. It was a great item for subscription. I just repurchased and it is not in the same packaging and very small. It no longer works with my model. It comes in a generic brown box. I am returning.

Very cheap and as effective as the stock ones. I'm skeptical that these carbon prefilters do much more than extend the life of the hepa filter but smells don't seem to last more than a day when it's running. Did notice black powder in hepa filter with some of them but doesn't seem to effect airflow. Just vacuum your hepa filters every time you change the prefilter and you'll never have any issues I've seen.

Used these precut filters for my Honey Well Hepa unit. They are so easy to use and being pre- cut make’s it so easy to replace.

Mine was the perfect size for my Honeywell.

I use these in my 3 large air filters. Just cut to fit. I can get 3 out of a sheet. I change these every month and saves me from having to change out the expensive air filter so often.

Très facile à installer

The filters fit perfectly & the Hepa Filter Fits perfectly.The Charcoal Filter is wee bit thicker. I just put one in , when they arrived won't know how good they are with filtering. Otherwise, everything all is perfect. Will know more , when it's time to change the Filter.

Have purchased previously I like the quality of them and the fit not disapointed

Replaced the OEM carbon filter when it was time with one of these replacement unit. Worked great . Fit was perfect and the pricing was better than OEM. Will buy again.

These Black Carbon Filters are not meant for what I am using them for but they fit and work better than the proper filters. THey also cost a good fraction of what the proper filters do.
