For over 20 years, WuJiang DeshengXin Purification Equipment Co., LTD has engineered premium HEPA air filters that transform indoor air quality. This guide explains how HEPA filters work, their benefits, and how to choose the right one for your home.

Why HEPA Air Filters Are Essential for Homes

Indoor air pollutants can be 2–5x more concentrated than outdoor air (EPA). HEPA air filters capture:

• 99.97% of particles ≥0.3 microns (dust, pollen, pet dander).

• Allergens triggering asthma or hay fever.

• Smoke and PM2.5 from wildfires or cooking.

• Mold spores and airborne bacteria.

1. Allergy Relief: Traps 99.97% of pollen and dust mites.

2. Child Safety: Reduces exposure to harmful particles.

3. Odor Control: Works with activated carbon layers to neutralize pet smells.

4. Long-Term Savings: High-quality filters last 12–18 months.

5. Quiet Operation: Advanced designs minimize noise (<30 dB).
