Review: These are expensive, but they work really well at catching dust and they are so easy to remove/install. The purifier (Shark 4) is very quiet and has no smell to speak of. These are a very good replacement
Review: I use it in my bedroom and I find that the replacement filters need changing too frequently. My bedroom is not in use for 18 hours a day so I wonder if I used it in a larger room how often would I have to change the filter. The filtering is fine with a new filter.

### ⭐⭐⭐⭐⭐ Review
*by D***. on 19 March 2026*

These filters are very easy to use you just open up the back of your filter and put them in not a problem at all. They do help collect the dust and other things they say they do. I’m very pleased with them. I also am pleased. They filter a large area.
