Review on AZEUS Purifier Purification Allergies Ozone Free by Danielle Martinez

This is a very good air filter at a good price. It's easy to use and relatively quiet on level 1 or 2, a little noisy on level 3, but that's to be expected. I only use level 3 (high) when cleaning floors and about an hour afterward. This helps to collect the dust that is thrown up, but it is not caught by the vacuum cleaner itself.
