How to Dry a Charcoal Filter

Charcoal-activated filters are common in air purifiers that draw air into the filter with a fan motor. Dust particles and other contaminants are trapped on the charcoal surfaces, resulting in cleaner air for your room. Because charcoal filters are expensive, rinsing them occasionally can save money on the cost of operating your air purifier over its lifetime. However, to work effectively, the charcoal must be dry before the filter is reinstalled.

Instructions

1. • 1

     Hold one end of the charcoal-filter frame in your fingertips and shake out excess water after cleaning.

   • 2

     Place the filter charcoal-side down on a flat surface outside in direct sunlight to dry. If cleaning during cold months, set the filter to dry on a windowsill.

   • 3

     Reinstall the filter in the air purifier by aligning the filter frame or cartridge with the slots on the appliance and pushing straight in.
