SED-1500 Pre-Filters - Change Every Month
The pre-filter is changed monthly and 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.
12 included. Pre-filters cannot be washed and should be changed monthly or as needed.
