I have a cat room that has no ventilation (cats never STAY there, it's their litter room), and I was looking for something to help pick up silicone dust from kicked up litter. A bigger unit would've been the wisest choice, obviously, but I was intrigued by this little thing. It's surprisingly loud for its size, though some might like the white noise by their bedside tables. I barely hear it anymore when I go down there. It does pick up dust, though not amazingly well. It seems to pick up a little bit of fur.It's great for the price, if you don't need a strong unit like a Levoit or something. I wish the charging port was at the bottom instead of the top. But I don't regret buying at all.
