A Black Friday "deal" is often a normal price next to an inflated list price. Here a air purifier only counts as on sale when its checked price is at least 15% below its own typical price over the last 90 days, from our price history. The best-rated models are listed too, since many are good value without a sale.
On sale now
No air purifier rated 3.8 or higher is 15% or more below its typical price at the last price check (October 22, 2026). Prices are rechecked through the sales; this list updates when one drops. See the recent price changes.
