How often should you change a MERV 11 filter?
every 30 daysThe filter you choose determines how often you need to change it. We recommend that most homeowners buy a mid-level MERV 10 or 11 filter and change that filter every 30 days — for better air quality and energy bill savings.
Can my furnace handle MERV 11?
Higher rated filters allow less air to flow through though and can force your furnace to work harder and possibly malfunction. A MERV rating between eight and 11 is adequate for most homes.

Are cheap furnace filters better?
