What matters most when choosing an air purifier for large rooms?
The best choice usually balances filtration performance, room fit, day-to-day noise, and realistic long-term ownership cost.
Should you choose based only on the biggest coverage number?
No. Coverage claims matter, but actual room size, noise tolerance, and how often the purifier runs matter just as much.
