What it is, and who it helps
A room air purifier draws air through a filter, usually a HEPA filter, which traps fine dust, pollen and smoke particles, and returns cleaner air to the room. For older people with allergies, asthma or heart and lung conditions, it can reduce the particles they breathe at home.
It works best in a closed room, such as a bedroom, with the doors and windows shut, and when the filter is kept fresh.
How to choose
- Choose a unit rated for the size of the room you will use it in, using the maker's room-size guide.
- Look for a true HEPA filter and check how often it needs replacing and what the replacement costs.
- Check the noise level on the lowest setting, since it will run at night.
- Avoid machines that make ozone, which can irritate the lungs.
Using it safely
- Place it with space around it, away from walls and curtains, and keep windows closed while it runs.
- Replace filters on schedule and clean the pre-filter, or it will stop working.
- Remember it does not remove gases or odours, and does not replace medical treatment.
Before you buy
Will a purifier cure my parent's cough?
It may reduce triggers, but a persistent cough needs a doctor's review.
How often should I replace the filter?
Usually every six to twelve months, depending on use and pollution. Follow the maker's guide.
