CLEANING AND MAINTENANCE (Regular Filter and/or Other Enhanced Filters)

Take out the (enhanced) filter before cleaning according to the installation instruction. Pay special attention that the silver

ion filter can't be cleaned with water, while active carbon, photo catalyst, low temperature conversion (LTC) catalyst,

formaldehyde eliminator, ca-techin or mite killing filter can (but can't be cleaned with brush or hard/sharp tools). Dry and

reinstall it after cleaning. Make sure to replace securely and properly.

FILTER LIFETIME

The washable filter will last a long time. But some (enhanced) filters may only have a lifetime of about one year under

normal conditions. As far as the silver ion filter, it will become invalid when its surface becomes black (green).
