SpacePak PurePak Electronic Air Cleaner & Return Air Box/Grille for 3642 (3.0-3.5 Tons)
mount 24 volt electrostatic air cleaner for the Spacepak®
system. Removes 97% of airborne pollutants .3 microns and larger.
Protects you and your family from mold, bacteria, pollen, smoke,
fine dust particles and VOC's. Does not create ozone, easy low
cost maintenance. If using this filter, you will not need the
return air box above, as this replaces it. 5-year power head warranty.
Filter media generally lasts between 2 and 4 months. Replacement
media is available below. Each box has 3 pads. Be sure to only
use SpacePak replacement media, because in the middle of the filter
there is an activated carbon center screen. This absorbs odors,
but more importantly it conducts the electrical charge that creates
the polarizing field.
