FiltersUSA recommends changing your Aprilaire filters at least every 10-12 months depending upon use. We carry a variety of Aprilaire brand name products. Scroll down to view them all, then simply click the BUY icon to place your item in the shopping cart for secure checkout.

Look for OEM. The acronym OEM stands for Original Equipment Manufacturer. This means that the product was manufactured by the original company that produced the product. For instance. If you have a Holmes air cleaner you would purchase a replacement filter that was manufactured by Holmes for Holmes air cleaner products. Other companies make replacement filters however, many of the generic knock-off's or fake brand name filters may be of inferior quality in order to get the price down. It may be an old cliche, but you do usually get what you pay for. FiltersUSA provides genuine OEM products together with some generic products that meet or exceed the manufacturers specifications. Preserve your warranty and look for Genuine OEM products.
