A little too early for a review. Why do you post this so soon after purchasing?!

The packaging for this filter
on August 17, 2026
Posted by: Customer
The packaging for this filter cartridge is absolutely terrible; the seller simply wrapped it in plastic film without even putting it in a cardboard box. I bought six at once but only use one at a time—where am I supposed to store the remaining five?

Buying for years first time left on front porch without box just before rain storm, at least had plastic covering. But could have been worst.

Great service—- really needed to filter out as much smoke residue as possible. It’s always a surprise to see how dirty the filters get— glad to have fresh ones!
