Key buying factors
HEPA filters capture 99.97% of particles down to 0.3 microns. True HEPA is essential for allergies. Some models add activated carbon for odors.
Look for decibel ratings under 50 dB on low for bedroom use. Models with silent mode or sleep mode are ideal for light sleepers.
Check CADR ratings; higher numbers mean faster cleaning. For small rooms under 200 sq ft, a CADR of 50-100 cfm is sufficient.
Cordless models run on rechargeable batteries for car or travel use. Plug-in units need outlet proximity. Weight under 5 lbs is convenient.
Consider long-term cost: some filters last 6-12 months, replacement can add $20-50 per year. Washable prefilters reduce waste.
Night lights, auto mode, timer, and air quality sensors add value. Ionizers may produce ozone; we prefer standalone HEPA units.
