The Space-Gard whole-house air purifier is a high-efficiency furnace air filter that removes dust, dust mites, mold spores, pet dander, pollen, bacteria, viruses, smoke, and other contaminants from the air circulating through the furnace system. The filter is designed to become more efficient with use. It typically should be replaced once a year.

Space-Gard 2200 Furnace Filter Assembly

Turn Off the Power
Turn off the power to the furnace. Most furnaces have a disconnect switch, which looks like a regular light switch, in an electrical box mounted onto or near the furnace. Flip this switch to shut off the power. Otherwise, you can shut off the power to the furnace circuit by turning off the circuit's breaker in your home's service panel (breaker box).Continue to 3 of 9 below.

Remove the Old Filter Media
Remove the filter access door by lifting it up and off of the metal furnace frame that contains the filter. Slide the plastic filter housing out of the frame. With the black plastic pleat spacers facing up, unsnap and release the plastic latches on the tops of both side panels. Remove the black pleat spacers from the top and bottom housing rails.
Open the plastic flaps on the top and bottom of the filter housing. Slide the cardboard ends of the old filter off the plastic hooks onto which they were fastened. Remove and compress the old accordion-like filter media and dispose of it properly.Continue to 4 of 9 below.

Install the Spacers
Install the pleat spacers one at a time. To place the first spacer, start at one end of the filter and carefully insert one tooth of the spacer into each pleat. Make sure you do not have any pleats doubled up.
Insert the remaining spacers close together, and near the first spacer; this makes it easy to insert the spacer combs into the open pleats.
When all of the spacers are in place, slide each spacer down to its corresponding notches in the top and bottom holding brackets of the housing, then snap the spacer into place in the notches.Continue to 8 of 9 below.
