90% of people don’t know! 3 fatal misunderstandings about cleaning half-mask filters

Does your half-mask filter get dirtier the more you wash it? Laboratory data shows that the protection efficiency of incorrectly cleaned filters drops by 67%! What's more terrifying is that moldy filter cotton may cause respiratory infections - this is not protection, it is chronic suicide!

Myth 1: Directly flushing the filter cotton with water = destroying the filter layer
❌ Incorrect operation
"Many people flush the filter cotton with the faucet like washing a rag, or even rub it violently with a brush"
⚡ Fatal consequences
→ Water pressure destroys the electrostatic adsorption layer (PM2.5 main filter layer)
→ Deformation of the fiber structure causes air leakage in the gaps
→ The measured protection efficiency plummeted from 95% to 28%
✅ Professional solution

Pat dust removal method: Use a soft brush to clean in one direction along the fiber direction
Deep cleaning technique: Medical-grade ultrasonic cleaner vibrates to remove dirt

Myth 2: Alcohol disinfection = chronic poisoning trap
❌ Incorrect operation
"Does it feel 'cleaner' to spray disinfection with 75% alcohol?"
⚡ Fatal consequences
→ Alcohol dissolves activated carbon particles and releases adsorbed chemical toxins
→ Residual alcohol evaporates and irritates the respiratory tract
✅ Professional solution

Safe disinfectant: quaternary ammonium salt non-corrosive disinfectant spray
Ultraviolet disinfection: portable UV lamp irradiation for 15 minutes to inactivate bacteria

Misunderstanding 3: Drying in the sun = breeding ground for mold
❌ Wrong operation
"After washing the filter element, expose it to the sun or dry it in the shade?"
⚡ Fatal consequences
→ The number of colonies in wet filter cotton exceeds the standard by 12.8 times in 24 hours
→ The risk of mold spores causing asthma increases by 4 times
→ Rubber parts age, crack and leak

✅ Professional solution

Three-minute quick drying technique: Use a centrifugal dehydrator to dry the water (applicable to auto repair shops/factories)
Anti-mold storage tips: Store with silica gel desiccant
