Buying Guide
Start by measuring your room size—match CADR to sq ft for effective allergy relief; undersized units fail fast. Prioritize True HEPA over basic filters, as they trap microscopic allergens. Check noise levels for bedrooms; look for <35dB sleep modes.
Interpret ratings wisely: 4.5+ with 1k+ verified reviews beats perfect scores from few buyers. Budget $150-250 for best value in $100-$300. The Levoit Core 300 shines for small spaces under $100, while Coway Airmega AP-1512HH handles larger allergies.
Avoid mistakes like ignoring filter costs ($30-60/yr) or skipping auto modes. Test coverage claims against AHAM standards. For allergies, Winix 5500-2 with plasma wave edges out basics. Compare via our list to match needs perfectly.
