1-Year Pack Air Purifier Replacement Filter for AP001R, True HEPA Filter, 4 Pack

These work great in my classroom. I run my machine all day and I can tell when it is not on. The filter is dark and dirty when I change it, so I know it is working. The machine is quiet and the perfect size.

Yeah these do work, have two RoseKM filters in operation in the kitchen. At first I thought it was a dust problem naturally since there is a gap behind counter sink area, found out later it was the fridge blowing against the wall causing an updraft over time to accumulate dust on the kitchen counter and area. Fridge was all the way back against the wall so when running compressor fan air force caused the dust top of counter. Have since moved fridge away from the wall which solved the problem. The RoseKM filters did work tho, sure did, they helped, and now with the two of them and fridge problem solved, there's no dust accumulation as it was. I hardly have to dust area or clean for dust now. Maybe once a month, that's how effective the two RoseKM filters work. The filters themselves last about three months or more, just check them occasionally. For such a small appliance with a disk shaped filter, amazingly they do a great job.

Well priced product for a well priced air purifier. I have 2 of the purifiers and replace a box of filters about once a quarter. As a smoker I definitely recommend them.

Yup they filter

I found this filter very well suited for me. It is quite and helps the litter box. The filter is great for the price. Just the right size.and very quiet.

Works well, easy to replace. They are small and just twist on and off the bottom of the air purifier, (sold separately). For being so small it sure did collect a lot dust, dirt and allergens from the air in my bathroom. Odorless, and light weight

I love this little air purifier it's it's perfectly out of the way you only need to change it every 30 days according to the air in your house or the air quality and it's super quiet
