Replacement Frequency: 12 months
HEPA Filter should be replaced every 12 months to ensure proper function. AeroShield™ HEPA should be used to ensure effective filtration and avoid voiding warranty.
AeroShield™ replacement HEPA filter is a true HEPA H14 air filter. Certified to eliminate 99.995% of particles 0.3 microns in diameter.* Aluminum alloy frame and gasket seal come standard on all AeroShield™ HEPA Filters.
*The 0.3 micron size is used for HEPA certification standards because it is considered the “Most Penetrating Particle Size” or MPPS. Testing has shown that particles larger than 0.3 microns are more efficiently trapped because of their larger size AND particles smaller than 0.3 microns are more efficiently trapped because they lack the mass to penetrate the filter. So 99.995% filtration of 0.3 micron sized particles is the least efficient filtration you will get with this filter.
Our immediate goal is to trap SARS-CoV-2 virus particles. The virus alone is approximately 0.12 microns, which will be filtered more efficiently than 99.995%.
Filter life can vary based on actual usage and pollution levels. Our estimates are based on the unit running 8 hours a day 5 days a week in the average dental practice.
