Product information

During the dry winter months, dry indoor air can be detrimental to your home and your family’s well-being. This is where the clever Bionaire BU6000 comes in. Ideal for medium-sized rooms, this compact humidifier gently disperses moisture into your home, alleviating dry air and making your surroundings more comfortable throughout the year.

Track a room’s moisture levels with the standalone hygrometer/thermometer, and set the desired intensity in moments with the easy-to-use control dial. A 4L water tank allows the BU6000 to run for longer (up to 12 hours) without a top up. There’s even an auto safety shutoff for your peace of mind. With its handy blue LED night light and super-quiet operation, the BU6000 especially suited to bedrooms.

Q & As

Rated 3.2 out of 5 by 6 reviewers.
Rated 1 out of 5 by Impractical and already broken down I've only had this product for a few weeks. The design makes it impractical to (i) move when there is water inside tank (it leaks from an opening in the back) (ii) fill up because of the shape Above all, it has broken down after just a few weeks. There is a loose plastic piece with a spring but it is not clear where it came from! I am going to return it and buy something else to replace. 05 March 2015
Rated 3 out of 5 by works but awkward to fill This humidifier works ok and generates enough mist but it seems to be designed for looks rather than convenience of use. It's awkward to fill with water and the blue light which you can't switch off is just stupid. It also emits a slight high pitched hum but that's probably common to all ultrasonic humidifiers and probably won't bother most people. 08 January 2015
Rated 4 out of 5 by Great Product This is a very good humidifier judging its price, it can be used during day or night. One single fill will lasts about 3 nights. The only downside is its a bit difficult to hold the water tank when re-filling water. My first one did stopped working after 8 months however as it's under the 2 year guarantee scheme John Lewis delivered my replacement for free within 5 working days. Great product and great after sales service. 11 November 2014
Rated 4 out of 5 by Humidifier This is my second humidifier and I have to say it performs silently and flawlessly with a descent size water tank, my room is a double bedroom fairly big and it caters for it perfectly, the only negative point I have to say about this product is it has a bright blue light that comes on when you switch it on, nothing a bit of tape cannot sort out. 23 January 2014
Rated 3 out of 5 by A few flaws but seems to work I've only had this item a few days now, so these are just my initial thoughts, and I haven't tried any of the competing brands so I don't have a useful basis for comparison. It seems to work all right - you can see the mist coming up from the machine and travelling about 2 feet before falling towards the ground. I was initially concerned that it might not travel too well about the room, and thus would effectively just hydrate the air immediately about the machine, but the standalone humidity reader that comes with the machine does show a difference, so it appears to be working. It's fairly quiet, but does make a little white noise - enough to disturb me when trying to sleep the first night, but after that I quickly got used to it. More annoying is the built in nightlight - who on earth at the manufacturer decided it needed a nightlight that you couldn't turn off? It's incredibly annoying, as it is bright enough to disturb my sleep. I suspect I'll end up having to cover the window on the unit with duct-tape, but then I'll no longer be able to see how much water is left in the reservoir. It's a rather silly design flaw. 20 April 2013
Rated 4 out of 5 by Very good at what it does Easy to use and does what it is meant to. Highly recommended 21 November 2012
