Review on Natures Miracle Odor Control Universal Charcoal Filter: Pack of 6 for Effortless Freshness by Nick Ross

These filters fit in my rather large Nature's Miracle hooded corner litter box which has started to release odours . They seem to hold the smell longer than the original filters that came with the kit. They are easy to cut, something I didn't need for a Nature's Miracle box. I had another litter box from a different brand that doesn't get used as often (my cats prefer large corner litter boxes) so in an attempt to save a buck I flushed out one of the used filters and it did just as well and almost as well worked well as a new filter on a rarely used box. It's nice to get a six pack and be set up most of the year (the corner box uses two). However, the main disadvantage is that the price of the filters fluctuates. I can't say what the best price for these is at the moment, but they work as advertised and are relatively recyclable.
