PR20.0 Replacement Pre-Filters
The pre-filter is the first stage in your PR20.0 Smoke Eater and should be changed at least once per month. It removes larger particles such as lint, hair, dust and pollen. The pre-filter is important because not only does it remove the larger particles, it also helps prolong the life of the HEPA filter in the system. Essentially, the pre-filter is the first line of defense in maintaining your system; therefore promoting better indoor air quality.
Pre-filters cannot be washed and must be changed monthly.
