Summary
The PuraMax 2 automatic litter box features a three-layer deodorizing system — sealed waste bin, odor-eliminator attachment, and a citrusy deodorizing spray that fires after every cleaning cycle. It's the most comprehensive built-in deodorizing solution for cat owners who want to eliminate the problem at the source.
A litter additive deodorizer with a mild, minty scent that pairs directly with your existing litter to neutralize odors at the source. Recommended by a professional pet sitter of 19 years as a go-to pairing with premium litters like World's Best.

Our take
If you're serious about litter odor, the real answer is attacking it at the source with an automatic box that has deodorizing built in. The PuraMax 2's triple system — including an automatic spray — is the most thorough passive deodorizing setup you can buy without spending $700.
This is the rare litter deodorizer that a professional pet sitter with a strong nose actually recommends — and she's tried everything. The fact that it smells 'low key pleasant' rather than overwhelming is a huge differentiator from most scented products.
