What to check before you buy
- Match the clean air delivery rate (CADR) to your room size.
- True HEPA filters capture fine dust and pollen; carbon filters help with odors and smoke.
- Check filter replacement costs and noise at sleep settings.
What to skip
Common mistake: Buying a small purifier for a large room.
We would also skip these at their usual prices:
- Molekule Air Mini+ ($299 – $399) – Skip it if you want value; it moves far less clean air than a $150 Coway Mighty.
When to buy
The deepest discounts usually arrive during the big summer sales in July, the October sales events and Black Friday through Cyber Monday in late November. A correctly sized purifier for the bedroom gives the most benefit for allergy sufferers.
