Arm & Hammer Universal Litter Filter

I swapped out the old filter and the difference in odor control was immediate—my whole laundry room smells fresher now. The double-layer design seems to trap everything, and at 90 days per filter, I won't have to think about it again for months.

The old filter in our hooded box was useless after a month, so I was skeptical, but this one actually holds up—90 days in and the room still smells fine. The double-layer design seems to trap the ammonia better than anything I've tried before.

Finally got around to swapping the old filter and the difference in odor control is honestly night and day. This one fits my hooded pan perfectly and the 90-day lifespan seems reasonable for the price.
