MERV 13 rated filters are a great choice for inpatient hospitals, general surgery, and other commercial spaces that require an increased filtration of airborne contaminants. The 85% of better efficiency for particles 3 to 10 micron in size, plus the added reduction of particles 1 to 3 microns in size at a 90% or better efficiency, means MERV 13 filters can assist in the reduction of bacteria in addition to dust, mold spores, and other common airborne contaminants.

SpiroPure MERV 13 Pleated Filters remove the following household contaminants: 

• Lint & Dust
• Dust Mite Debris
• Pollen
• Mold Spores
• Pet Dander
• Auto Emissions
• Smoke
• Tobacco
• Bacteria
• Smoke

We recommend replacing your whole house filter every 6 to 12 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.
