Purifying Liquid Refill（4 Bottles）

Wasn't sure these refills would make much difference, but the litter box corner of my apartment actually smells neutral now instead of that faint ammonia smell. The four bottles last me a few months, so the cost per refill works out pretty reasonable.

The difference in smell is honestly night and day since I swapped in this refill. I have two cats sharing the PuraMax and I no longer get that litter box whiff when I walk past it. Four bottles should easily last me a few months.
