Litter-Robot 3 Carbon Filters by Whisker, 6-Pack

Works as it should keeps smell down

If the price has you thinking about the off-brand filters, let me save you money now. These are worth it. I tried saving a penny myself and wound up with the cat box stinking up our home. Not what I bought a Litter Robot for! Finally bought these from Whiskers which, unlike the others - are thick and fit the slot perfectly. No more odor — they work perfectly and are worth the cost!

I was needing to replace original litter robot 3 filters. These worked perfectly. They fit snug and keeps the odor down between box cleaning. Would recommend.

We have a litter robot and one cat. The litter robot is amazing and has been a game changer for us. The filter helps with the odor, but don't expect miracles from the filters. They help, but are not the sole source for solving odor problems. We tend to use 2 at a time for better control but we also don't change them out as often as recommended, so it doesn't wind up costing more to use more at a time. The fact we leave them in longer makes no difference in how much odor is controlled whether we use them 30 days or 90. That being said, they are the name brand filters, the fit perfect for the unit. I would recommend using this item over a knock off brand since it's made to fit the unit and you don't have to worry about modifying an off brand.

Awesome

Does not eliminate odor bout the brand from wischer

I just keep thinking "for the cost, do I really want to keep wondering if these make a difference?" I'm still using them for the time being but I'd be happy to find something that I can definitely tell works. Don't get me wrong. The room doesn't STINK. But you know there's a litter box in it. Maybe technology isn't that far enough along yet.

Not any better at controlling odor in the drawer.
