Rated Room CoverageMedium rooms, up to 750 sq ft
The Honeywell HPA104 is a mid-sized True HEPA + activated carbon air purifier rated for medium rooms up to 750 sq ft, with a CADR of 210 (dust/pollen/smoke). It operates at 52 dB on high, quieter on low, lacks smart features (manual 3-speed control only), and uses standard Honeywell filters (~$30–40, replace every 6–12 months). The brand enjoys strong recognition in home-appliance circles, and reviews praise solid airflow and reliable motors. Downsides: no air-quality sensor, no app/scheduling, and moderately priced for its feature set. Best for allergy/asthma sufferers seeking trusted filtration without frills—not for tech-forward buyers.
