If you suffer from extreme allergies, you’ll want to look for a filter with at least a MERV rating of nine. These filters capture particles as small as one micron.
How long do MERV 11 filters last?
The basic recommendation for furnace filters replacement is every 3-4 months for MERV 8, every 6 months MERV 10 and 11 and every year for MERV 16. There are other several factors to consider when determining when to change your home air filter.
