So far so good!

Fantastic air purifier! I bought it to set on top of a cabinet that houses my cats litter box. Completely eliminated all odors, not to mention my entire 3rd floor has significantly less dust than before. Saras Vac Shack is second to none ! I would have never known it was Refurbished. It arrived clinically clean and wrapped in plastic. I own a filter queen vacuum as well and will never own anything else besides filter queens. This defender was a great addition.

We like it very much. It is doing a great job of keeping the air cleaner, have much less dust. The only thing I don't like is that it is very noisy on low setting and way too loud on high. We let it run on low 24-7. Very satisfied.

The best air cleaner-purifier on the market. It eliminates house smells, dust, molds and mildews common in areas of the country with raining weather. I have tried three different brands before and each one had various deficiencies. The Defender 4000 out cleans and out performs all other air cleaners and air purifiers combined and it does not produce O3!

This purifier has made it so I was able to stay in my condo when smokers moved into my part of the bldg.
