Best Air Purifiers (2026)
Air purification went from allergy-niche product to biohacker-adjacent recovery hardware in 2024–2026, driven by wildfire-PM2.5 awareness and the indoor-air-quality crossover into sleep / longevity protocols. The category splits cleanly: clinical-tier HEPA references (IQAir, Molekule), consumer premium (Dyson, Coway Airmega, Blueair), mid-budget smart (Levoit, Winix), and entry budget (Levoit Core 300). ONDA scored the ten most credible air purifiers of 2026 against the same six axes — filtration technology, CADR and coverage, build and noise, smart features, maintenance cost and value.
