HOW EFFECTIVE IS A HEPA FILTER?
HEPA filters remove at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter. This makes it the ideal choice for the EnviroMate TANDEM.
WHY YOU NEED IT
A HEPA filter is beneficial for asthma and allergy sufferers, because the HEPA filter traps the fine particles (such as pollen and dust mite feces) which trigger allergy and asthma symptoms.
