Summary
Wirecutter's top pick and a Reddit community favorite, the Coway Mighty delivers powerful HEPA filtration at a mid-range price. It covers large spaces efficiently while running quietly enough for bedrooms.

- Covered by RTINGS.com as a top-tested model
- Available widely and competitively priced at ~$240
Cons

Our take
This is the air purifier I'd tell any allergy sufferer to buy first — it's the consensus pick across both expert labs and real owners, and it's hard to beat at this price.
If the Coway is sold out or you want something with a bit more airflow punch, the Winix 5500-2 is what Reddit's allergy sufferers actually swear by — and that real-world track record matters.
