MERV 8 rated air filters are the most commonly chosen replacement filter in the home. This is because the 70% to 85% efficiency of size 3 to 10 micron particles that comes with a MERV 8 filter is perfect for removing airborne contaminants without impeding the airflow in your HVAC system.

SpiroPureMerv 8 Pleated Filters remove the following household contaminants:

• Lint & Dust
  
• Dust Mite Debris
  
• Pollen
  
• Mold Spores
  
• Pet Dander

We recommend replacing your furnace filter every 3 to 4 months for maximum efficiency and cooling and heating system life. A dirty filter restricts airflow, which can put too much strain on the system. As a result, there can be motor burnout and an overheated system. The leading cause for HVAC system failure is a dirty air filter.
