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

I received a great deal for four. The have always made the quality air in our bedrooms 10X better, and you can tell the difference when you need to put a replacement in.

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

Its a good deal cheaper then buying one filter every 4-6 months at a time.

I’m sure if I did have the right size machine it would have been perfect.

Whats not to like and it cleans the air we breathe

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

Expensive havent found anything cheaper that fits yet!

Quiet and quickly efficient, highly recommended.

Filter fit perfectly in my partu air purifier, have this set up for subscribe and safe every 5 months to replace my 2 air purifiers in my home. Works great!

It works
