Residential Air Purifiers
Portable HEPA air cleaners provide dedicated filtration for bedrooms, living rooms, and open floor plans. We evaluate CADR (Clean Air Delivery Rate) at real-world acoustic levels rather than relying on noisy maximum fan speeds.
Essential Buyer Selection Criteria for Air Purifiers
- True HEPA vs. HEPA-Type: Medical/True HEPA must capture at least 99.97% of particles down to 0.3 microns. Avoid generic 'HEPA-type' filters with unverified efficiency.
- CADR & Air Changes per Hour (ACH): Look for AHAM-verified CADR numbers that match your room volume. A minimum of 4.8 air changes per hour is recommended for allergy and smoke mitigation.
- Sleep-Mode Acoustic Levels: Many purifiers only deliver their advertised CADR at ear-splitting 60+ dB noise levels. Compare CADR output at low and medium speeds for bedroom use.
