Smilyan BS-03 True HEPA Replacement Filter for PARTU BS-03 Air Purifier and Slevoo BS-03 HEPA Air Purifier（Not Fit BS-01）, 2 Pack 3-in-1 HEPA Air Filters

This was very easy to install in my air purifier.

This filter goes with a very good machine.

Great service and fit properly.

My husband has COP D We use it by his chair all the time Its very important for him to have clean air to breathe And this does the job

the size is larger, it does not fit the purifier and that is compared to the size of the original purifier

Great value replacement filter.

Does not clean the the air

Great price for two. Working well

Works great!!

Eats my cigar smoke so the wife doesnt complain..
