Dirty Filters = Toxic Air? Lab Tests Show 12x Bacteria Growth on Overused Filters!

Data-Driven Shock:

PM2.5 filtration efficiency drops from 98% (new) to 63% (6-month-old filter).

Mold colonies on old filters exceed safety limits by 8x (microbiology lab report).

User Myths Debunked:

① "Visibly clean filters = safe" (Microscopic fiber structure comparison).

② "Washable filters save money" (Post-wash efficiency plummets 55%).

Action Plan:

• Smart reminder: Integrate IoT filter life monitoring (Showcase app dashboard).

• Replacement guide: Frequency based on pet ownership/smoking/pollution levels.
