As long as you don't spray Bio-Kleen Aire in your face or drink it, it's terrific for cleaning up smelly cat boxes and cat spray on wood surfaces. Most cat spray "odor removers" are for carpet and they leave an overpowering so-called fragrance. Bio-Kleen is odorless and simply destroys the odors. It is anti-bacterial and even said to have a long lasting effect. I know it is fine to use on wood - I used it on furniture and floors where cats had sprayed - it did not harm the finish and it removed the odor and evidence of spraying when the areas were tested with a black light. For cat people with hardwood floors who want fragrance free products, this is one to try. Works on mold, too.

Pros: This stuff is truly fragrance-free, non-toxic, and it works

Cons: Label says it may be an eye irritant and harmful if swallowed

This is really great. It helps keep dust down in your house. Also for people with allergies or those that smoke. It helps remove dander and smoke from the air. Filters can sometimes become tricky to find.
