1.Remove any plastic or paper wrap from filter. Take care not to cut, bend, crimp or otherwise damage or remove the cardboard frame around the filter media.

2.Remove and dispose of the existing filter in your home furnace or air conditioning system. Keep in mind that the used filter contains particulates that, with improper handling, can be re-introduced into the air. For best results, immediately place the soiled filter in a plastic garbage bag, tie the top, and dispose of properly.

3.Insert your AllergyZone filter into the filter opening of your home furnace or air conditioning unit with the arrow located on the frame pointing in the direction of air flow. The solid yellow side of the filter should face the side of the unit in which the return air duct brings air into the furnace or air conditioning system.
