We know how frustrating it can be trying to find a fair price on the right furnace air filter at a big box retail store. Those retailers typically add a big mark-up on their filters and charge more than they should, but there’s no need for you to pay those high prices. We make shopping for replacement furnace filters easy and affordable. Our prices are low, and you can be confident in the quality of our furnace air filters. Other online furnace filter retailers don’t make it clear that you’re buying generic no-name filters. Those generic filters might be compatible in size, but are usually poorly made using inferior materials. Dan the Filter Man, only offers quality, brand-name furnace filters in all the most popular sizes for all the most common furnaces. Choose from 1”, 2”, 3”, 4”, 5” and 6" filters from brands such as Aprilaire, Carrier, Honeywell, Lennox, and many more.
Check out our wide range of replacement furnace filters and take advantage of Free Shipping for all orders over $150+!
