There are air filters of all different materials, sizes, costs, and functions, so it’s essential to understand the differences when shopping for a replacement filter. When it comes to air filters, it’s also important to understand MERV ratings.
MERV, or minimum efficiency reporting values, rate filters on a scale from one to twenty. Lower quality filters have a lower MERV rating. In contrast, higher MERV ratings indicate the elimination of the smallest of particles by your filter.
The Importance of Fresh Filters
Any home with a central heating and cooling system and ductwork installed also has an air filter that will need regular replacements over time. Your air filter is the first line of defense against airborne irritants that would otherwise sneak their way into your home and disperse throughout the air ducts.
Replacing your air filters regularly can not only ensure improved air quality but also keep your system running efficiently and for years to come. Air filters should be replaced every 90 days to keep pristine air flowing through your home sweet home!
