The best humidifier for bedroom use for most UK buyers is the Dreo 3L Humidifier with Sensor. It showed more than 1,000 bought in the past month on Amazon UK when we checked, has a 4.4 star rating from over 5,000 reviews, and costs about £36. It runs for up to 30 hours on one fill in sleep mode and shows the room's humidity on its display. For the easiest cleaning, the Levoit 3.2L has a tank and water parts that can go in the dishwasher. On a budget, the Homvana 3.6L was about £31.
Before you buy, check you actually need one. Most UK homes are too damp in winter, not too dry. A humidifier only helps if your bedroom humidity is below about 40%, which can happen with the heating on all day. If it is above 60%, or you see condensation on the windows, you need a dehumidifier for a damp bedroom instead. We have not tested these ourselves.
40–60%
The indoor humidity range most often recommended for comfort. Below about 40% a humidifier can help; above 60% you risk condensation and mould

Use a Humidifier Safely
Empty, rinse and dry the tank every day or two, and clean it properly once a week following the manual, as standing water can grow mould and bacteria. Do not push humidity above about 60%, or you may get condensation and mould. Use filtered or distilled water in hard water areas to cut white dust and limescale. Keep warm mist models out of reach of children and pets. Only put essential oils in the aroma pad or tray, never in the tank. A humidifier is not a medical treatment, so see a pharmacist or GP if you are worried about a cough or breathing.

Frequently Asked Questions
Common questions about bedroom humidifiers in the UK
For most people we pick the Dreo 3L Humidifier with Sensor. It shows the room humidity, runs up to 30 hours per fill in sleep mode and was an Amazon UK best seller when we checked, for about £36. Choose the Levoit 3.2L for dishwasher-safe parts, the Homvana on a budget, the Vicks for warm mist, or the Levoit Smart for an auto humidity mode.
Check the humidity first with a cheap hygrometer or a humidifier with a display. Below about 40%, a humidifier can help. Above about 60%, or if you get condensation on the windows, black mould or a musty smell, you need a dehumidifier. Most UK homes need a dehumidifier in winter. See our best dehumidifier for damp bedroom UK guide.
Somewhere between about 40% and 60% is the range most often recommended for comfort. Aim for the middle. Air that is too dry can feel scratchy on your throat and skin, and air that is too damp leads to condensation and mould.
Some people find moist air more comfortable with a blocked nose or dry throat, but a humidifier does not treat a cold. Keep it clean and do not over-humidify. For advice on colds, coughs and when to get help, see the NHS website or ask a pharmacist.
Cool mist humidifiers like the Dreo, Levoit and Homvana use less electricity and are safer around children, as nothing gets hot. Warm mist models like the Vicks heat the water, which some people like with a cold, but they use more power and can scald if knocked over.
Many parents do. Choose a cool mist model, place it out of reach and away from the cot, clean it often and do not add essential oils. Keep an eye on the humidity so the room does not get damp. Follow your health visitor’s advice if your baby has breathing problems.
You can, but in hard water areas ultrasonic humidifiers can leave a fine white dust and build up limescale. Dreo suggests purified water in London and the South East. Filtered or distilled water helps. Always empty and refill rather than topping up old water.
Empty and rinse the tank every day or two, let it dry, and give it a proper clean about once a week following the manual. Descale it if you see limescale. The Levoit 3.2L has dishwasher-safe water parts, which makes this much easier.
They can if you overdo it. Running a humidifier in a room that is already above 60%, or all night with the door shut in a small room, can cause condensation on cold windows and walls. Use a display or hygrometer, or an auto mode like the Levoit Smart’s, to keep humidity in check.
Cool mist ultrasonic humidifiers use little power, usually far less than a heater. Warm mist models use more because they heat water. Check the wattage on the listing and use our appliance running cost calculator method, or measure yours with an energy monitor plug.
Ready to sleep without a dry throat?
Our top pick, the Dreo 3L Humidifier with Sensor, shows your room humidity and runs for up to 30 hours on one fill in sleep mode (listing says).
