Amaircare Single Pre-Cut 8" Charcoal Pre-Filter (compare to Amaircare Part # 92012-11) can be used to replace the pre-filter in selected Amaircare portable HEPA air purifiers. Activated charcoal pre-filter reduces odors and captures larger airborne particles, which helps extend the life of the HEPA. Our hassle-free pre-filter is ready to use, with no measuring or cutting required.
The pre-filter is designed to last for 3 months, depending upon use and the environment. If your indoor air has very high levels of airborne particulates, odors or smoke, the filter's service life may be shortened. One way to tell it is time to replace the pre-filter is by its color. The Amaircare pre-filter is almost black when new, and turns a light gray color when it needs to be changed. Package contains one (1) 8" Pre-Cut Charcoal Pre-Filter.
