12 x 20 x 1 Air and Furnace Filters

Are you looking for a replacement 12x20x1 air or furnace filter? Well look no further. US Home Filters offers a wide array of filters in various sizes, MERV ratings, and other options. You should replace your filter on a regular basis. It is a simple home cleaning task. First, if the floor or area around your furnace or air conditioner is dusty, make sure to sweep or vacuum. Turn off the unit, and then open the panel door. Locate the filter, which is usually a framed-mesh rectangular screen, and remove it. Make sure you know what kind of filter you have – some need to be replaced immediately, but others are reusable, and you can use a hose to rinse away any dust particles. Once it is dry it can be returned to the furnace or air conditioner. If the reusable filter has gotten too old or you have one that needs replaced every time, you can use any filter that is the same size. Then you will be well on your way to breathing easier in your home.
