Buying Guide
Why HEPA Matters
HEPA (High-Efficiency Particulate Air) filters capture 99.97% of particles as small as 0.3 microns. This includes:
- Dust mites
- Pollen
- Pet dander
- Mold spores
Sealed vs Non-Sealed Systems
A sealed system ensures all air passes through the HEPA filter. Non-sealed systems may leak unfiltered air through gaps.
Bagged vs Bagless
Bagged vacuums are generally better for allergy sufferers because:
- Less dust exposure when emptying
- Better containment of allergens
- Bags act as an additional filtration layer
