FAQs & Answers

  1. What does MERV 8 rating mean for air filters? MERV 8 filters capture a moderate level of airborne particles such as dust, pollen, and mold spores, making them suitable for most residential HVAC systems.
  2. Can I extend the lifespan of a MERV 8 filter? While MERV 8 filters typically should be changed every 3 months, those in low-pollution environments with no pets may sometimes last longer, but regular checks are essential.
  3. Why should I change my air filter more often if I have pets? Pets shed fur and dander which can clog air filters faster, reducing air quality and HVAC system efficiency, so changing filters every 1-2 months is recommended.
