So far no litter box odors. This box is the worst offender being in an open upstairs hallway and available to all four cats 24/7.
In the past my wife and I have raced up the stairs or out of bed to scoop this box passing through a most horrendous odorous cloud before it spreads house wide. The fan has been operating for a few weeks. Before we always knew that the box needed scooping. Well before reaching it. Now we have to remember to check. I've regularly walked past not knowing 2+ cats have made a pit stop.
The bracket is mounted on the wall just above the litter box. We have a shy cat that uses this box almost exclusively and who creates the awful odor. My worry was the noise or vibration from a fan directly on the box might deter her from using it. That would be disastrous. All cats seem to be ignoring it. I'm sure the low noise and near vibration free characteristics of the fan heavily contribute to this. The fan is currently running at it's slowest speed. I have noticed that when turning ON there is a minimum amount the switch has to be moved beyond OFF or the fan makes considerable noise.
My only concern with the filter was of the fan's longevity but that was addressed by the company. It carries a lifetime warranty.
The first filter fan was DOA. This was quickly address by company. Their overall excellent service kept the rating at five stars despite the four shown which I can not seem to change.
So far we are happy enough to have ordered another. The second of three planned.
