  • CNET’s latest review, “Best Air Purifiers of 2026,” highlights how winter’s poor indoor air quality can be mitigated with new models. The tech site tested over a dozen units in a lab setting, measuring T90 (time to remove 90 % of particles), noise, and energy use. Five purifiers earned top‑tier status, each excelling in different areas: one balances speed, quietness, and smart features; another boasts the fastest overall particle removal but is pricey; a third offers the lowest energy draw yet slower high‑fan performance; a fourth delivers fine‑particle clearance with a sleek bamboo design; and a fifth excels at coarse‑particle removal but is loud and heavy. The review underscores that choosing a purifier depends on space size, noise tolerance, and budget.
