What actually matters in a air purifier
| Spec that matters | Why it decides the purchase |
|---|---|
| True HEPA, not "HEPA-like" | the filter grade is the entire product; certified H13 HEPA captures particles down to 0.3 microns |
| Room coverage in square feet | match the rating to your room, bedrooms can round down, open plans round up |
| Filter replacement price | the machine is a subscription — check the yearly filter cost before buying |
| Sleep mode noise | bedroom units run all night; low-speed decibels matter more than max |

Mistakes to avoid
- Oversizing down: a purifier rated for 300 sq ft will never keep up with a great room
- Forgetting filter costs — a cheap unit with pricey filters loses over a year
Care and upkeep
Replace the HEPA filter on the maker's schedule (usually 6-12 months); vacuum the pre-filter monthly.
Frequently asked questions
Where should I place an air purifier?
Near the pollution source or in the room you occupy most, a foot or two from walls so intake can breathe.
Do purifiers help with odors?
Only models with an activated-carbon layer; HEPA alone captures particles, not gases.
