Yes, MERV really matters. The MERV rating, or Minimum Efficiency Reporting Value, measures how effectively a filter captures particles of different sizes. Higher MERV ratings (13-16) capture smaller particles, such as pollen, dust, and bacteria, improving indoor air quality. For most households, a filter with a MERV rating between 8 and 13 is suitable, balancing air flow and filtration efficiency.
