Discount Filters carries top of the line Honeywell furnace filters of all sizes. Save energy by replacing your Honeywell air filter every 3 months which will keep your HVAC unit cleaner. A clean air furnace will improve energy efficiency by reducing the particles floating in your home's air.

Save Your Furnace Tip #8:

If you have a 6-month filter, schedule your filter changes when daylight savings changes. When you "spring forward" or "fall back" setting clocks around the house, change your filter at the same time.
