My PRO air purifier gives off an unpleasant odor.

At first, like any new appliance, an air purifier may give off a "new" smell. Rest assured, this smell is not toxic! The smell can also come from a dirty filter. In fact, it can give off a dusty smell. To avoid bad smells, always replace the filter at the indicated time. Run your air purifier continuously for a few days to dissipate the smell. For optimal use, leave your air purifier on permanently. It consumes less energy than a low-energy light bulb!
