The Focus G4 Filter is a MERV 7/8.
- The filter replacements are for both the Focus 200 ERV and HRV Ventilation Device (see picture to the left)
- It is recommended to order the filters in quantities of two so both filters in the units are replaced at the same time to ensure optimal indoor air quality in the home.
Additional models of the Focus 200 Filters Include:
- #9349-Focus F7 Filter- MERV 13
