Filter order for Family series units
To achieve healthy and clean indoor air, the filters in an air handling unit have to be changed on a regular basis. The change frequency depends on the type of filter used and also the quality of the outdoor air. The recommended replacement frequencies are mentioned with every filter type.
Enervent Family units are equipped with either class F5 or class F7 filters. Class F7 filters are so called fine filters, which filter out for example pollen from the outdoor air.
