HEPA Filters Explained
HEPA filtration is crucial for allergy sufferers and anyone concerned about indoor air quality. This guide explains what HEPA means and why it matters.
What Is HEPA?
HEPA stands for High-Efficiency Particulate Air. True HEPA filters capture 99.97% of particles 0.3 microns or larger, including:
- Dust mites
- Pollen
- Pet dander
- Mold spores
- Bacteria
Types of HEPA
True HEPA: Meets strict standards, captures 99.97% of 0.3-micron particles.
HEPA-Type/HEPA-Like: Less effective, typically 85-90% filtration. Not suitable for severe allergies.
Sealed HEPA System: Entire vacuum is sealed to prevent air leaks. Air only exits through the HEPA filter.
Benefits
