We use dual filter cartridge (5 micron and 1 micron) together with UV light. This particular filter was a direct replacement for our system. The price is reasonable, shipping was fast and it saved us 2 hours round trip to pick up filters where we usually buy them every year. About the edit: Others have noted that these filters are not individually wrapped. From 2021 both filters are individually packed.
