Better Air Purifiers

a year ago

HEPA filters are not ideal for in-room air purifiers due to high resistance and inefficiency in cleaning already circulated air.
Clean Air Delivery Rate (CADR) is a better metric for comparing air purifiers than just filter type.
Noise levels are a critical factor; many purifiers are too loud, leading to underuse.
Custom filter sizes in purifiers lead to higher costs and inconvenience, unlike standardized HVAC filters.
Poor design choices, like floor placement and upward airflow, reduce efficiency and take up space.
Lack of innovation in the market, with top models remaining unchanged for years.
Proposed ceiling fan-based purifier design uses standard HVAC filters, offering high CADR with low noise and cost.
Design includes a frame for filters and a mesh cover for aesthetics and pre-filtering.
Encouragement for others to develop and commercialize the proposed design.
