Home Fragrance

A reed diffuser gives a steady, low-level fragrance for weeks with no flame, which suits hallways and bathrooms. A candle adds atmosphere and a fuller scent while it is lit. A room spray gives an instant refresh before guests arrive. Many homes use all three: a diffuser by the door, candles in the evening and a spray for quick changes.

A 100 ml diffuser usually lasts two to three months, depending on room temperature, airflow and how many reeds you use. Turn the reeds every week or so for a stronger scent, and use fewer reeds to make it last longer. Replacing the reeds when you refill keeps the fragrance throw strong.

Somewhere with gentle air movement, such as a hallway or near a doorway, but away from direct sunlight and radiators, which make the oil evaporate quickly. Stand it on a coaster or tray, as the oils can mark wood and painted surfaces. Keep it out of reach of children and pets.

Some essential oils, including tea tree, eucalyptus and citrus oils, can be harmful to cats and dogs, particularly in concentrated forms. Keep diffusers out of reach, ventilate rooms and avoid scenting the room where a pet sleeps. If your pet seems irritated by a fragrance, stop using it and ask your vet.
