Different filters: HEPA, activated carbon, pre-filters

1) Types of Air Purifier Filters

• HEPA Filters — Capture 99.97% of fine particles (dust, pollen, smoke)
• Activated Carbon Filters — Absorb odors, VOCs, and gases
• Pre-Filters — Trap large dust and hair, extend HEPA life

2) Cleaning HEPA & Pre-Filters

Not all filters are washable. Pre-filters can usually be rinsed monthly. For HEPA, vacuum gently with a soft brush attachment — never soak in water unless labeled washable.
