We spend most of our time indoors, so the air at home affects comfort and breathing. The good news is that fresher air needs no expensive equipment. A short, regular routine is enough.
Morning and evening reset
- In the morning, open windows for 5 to 10 minutes, ideally with a draught through two rooms.
- While airing, shake out the bedding and make the bed.
- In the evening, air the bedroom before sleep.
- If traffic, smoke or pollen is heavy outside, air for a shorter time or at a calmer hour.
Cooking and cleaning
The US Environmental Protection Agency (EPA) advises using an exhaust fan that vents outdoors while cooking, and bringing in more fresh air during messy tasks. Wipe dust with a damp cloth and use scented products and candles sparingly. Removing pollution sources is usually more effective than ventilation alone.
To keep the routine going, stick a reminder on the window or set a phone alarm. After a week, notice how you feel in the morning and whether the room is less stuffy. Clean the filter of the hood and purifier as the maker instructs, because a dirty filter does not do its job.
Humidity and humidifiers
The EPA suggests keeping indoor humidity below 60 percent, ideally between 30 and 50 percent, and an inexpensive meter will show the level. Clean a humidifier regularly and rinse its tank as the manufacturer instructs.
If you have asthma, allergies or ongoing breathing problems, talk to your doctor. An air purifier can be an extra, but it does not replace airing or treatment.

Common questions
Is airing once a day enough?
For many homes, a short airing in the morning and evening works, with extra airing while cooking or cleaning. Adjust the routine to your own situation.
Do I need an air purifier?
Not necessarily. First cut pollution sources and ventilate. If you have asthma or allergies, ask your doctor what suits you.
Before first use
Choose products for your dietary routine and care needs. Follow a healthcare professional’s advice for diagnosis and treatment of symptoms. Check suitability first during pregnancy and for use by children.
