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

Everything works as far as I can tell and I have no problems with the filters while the purifier is running. I did knock one star down, primarily because it is hard to get it in as the size is very tight and does not allow for an easy closing of the lid. Otherwise, I have no issues.

Product was easy to install, arrived in a sealed package, and has been working as expected in my air filter. Will definitely purchase again.

It works well

The filters do a great job at what theyre supposed to do. It catches so much dust and pollen in my apartment, and I replace it every once in a while to ensure I have clean air. Super easy to install.

I am returning these the filters I received. They were not what I wanted. I have reordered the filters. The pictures you see was not what I got.

Does not clean the the air

Fast and fair

I appreciate when technology does what it says it will...best to you!

Purchased the filters with the purifier as a bundle. When it was time to change the filter, the filter didnt fit, and the return window has passed!

This filter is garbage. It doesn’t clean the air very well at ALL.
