What to look for when buying an air purifier
The right air purifier will clean your air for years to come, but the wrong one will just waste your money. Read our tips before you buy.
Calculate the CADR needed for your room size
The higher the CADR (stated in CFM, or cubic feet per meter). the higher the air cleaning power. Use our CADR calculator to find out how powerful an air purifier needs to be based on the size of your space.
Choose the right filters for the job
If you've got hairy pets, look for a removable pre-filters. If you want to tackle allergens like dust, pollen and mold, you'll need a HEPA or MERV filter. And if you want to remove odors and chemical gases, you'll need pelleted carbon.
Factor in how noisy the air purifier will be
For quiet rooms like a home office or a bedroom, you'll want an air purifier powerful enough to clean the air while generating less than 45 dBA. Read our full reviews to find out if the model you're considering is a good option for your quiet space.
Calculate the long-term running costs
Your air purifier will need its filters replaced eventually, so take your time to find out how much the replacements will cost you over a year. There are models that will be cheap to buy but expensive to run!
Consider if you need smart features or an app
Special features like smart functions, app connectivity, onboard air quality sensors or remote controls are handy perks that can make life easier. However, you shouldn't sacrifice CADR or performance over nice-to-have features - if your budget is tight, drop the fancy functions.
