## Customer Reviews

### ⭐⭐⭐⭐⭐ Great quality filters, much cheaper than other options!
*by R***N on December 31, 2023*

I replace my filters a couple times a year with these, and they work great. As far as I can tell they are exactly the same as the more expensive brands, and filter fresh clean air. The free carbon filters are also nice for odor control, but they do restrict the flow of the filter fan(at least on mine), so I tend to not really use them.

### ⭐⭐⭐⭐⭐ Works nice
*by V***N on December 18, 2024*

### ⭐⭐⭐⭐⭐ Aer1
