What is a humidifier?
A humidifier is a device used to increase humidity (moisture) within a room or home. Typical consumer humidifiers such as the Maplin 5L Ultrasonic Humidifier are ideal for single rooms.

How does an ultrasonic humidifier work?
Ultrasonic humidifiers work by immersing a small piezo-electric transducer in water, this vibrates at ultrasonic frequency, typically 20-40,000 Hz. These vibrations create water droplets to be emitted as a cool, fine mist. Standard tap water can be used.

What are the benefits of using a humidifier?
Overly dry air within the home can cause and exacerbate a number of health problems including dry eyes, sinus problems, sore throats and dry mouth. Adding moisture back into the home environment can help alleviate these problems.

Rated 4 out of 5 by from Bought this product today and very pleased with it. PROS: The capacity of water it can hold is excellent. The ability to adjust output which in turn will adjust the length of time it can operate for is good. The ability to switch the night light off is good, although there is still a little backlight. CONS: The device is a little on the noisy side for me, at being <35dB it isn't what I would call quiet, if it operated at <20dB then I might consider it to have that accolade. So all the other reviews of it being quiet I find a little odd, maybe I am over sensitive. If it was quieter I would have given it 5 stars.

Rated 5 out of 5 by from I have brought numerous humidifiers over the years but this one is the BEST! It is quiet, looks good (blue light is a nice feature and quite soothing to look at), the water tank is huge and the amount of cool mist, which is generated (dependent on the selected setting) is very impressive. I find this product beneficial (especially in this hot weather) because I am unable to open my bedroom window due to my neighbours being chain smokers. Therefore, the smoke tends to waft through my bedroom window (when it is open). Thankfully, the humidifier keeps my room cool and also cleans the air. Overall, this product is AWESOME and I would highly recommend it to others. WELL DONE, MAPLIN.

Rated 5 out of 5 by from Bought it a few weeks ago and love it! Easy to use, steam comes out immediately as you turn it on, it goes upwards and you can change direction of the steam, it gives a cool mist which is quite nice in the summer like fresh air. It is quiet and doesnt disturb me from listening to music or watching tv. The blue light makes it look nice and the fact that it holds 5 litres of water means I dont need to refill as often. You do need to remember to turn it off before water runs out as it doesn't have a timer/auto switch off. Good value overall!

Rated 5 out of 5 by from Bought this product because I had sinusitis and was told that they can help , so after looking around I found this one which was the cheapest I could find and also having a huge water tank was a plus too . I can't fault it in anyway put it on full and inhale to moisten and loosen mucus build up leave on low at night to aid sleep and as central heating dries the air out when it's on I use it too it's just a great product

Rated 5 out of 5 by from This is the 3rd humidifier I've used and is by far the best. The steam spout points upwards which distributes steam in the air. Previous ones pointed forward and made everything nearby damp. The spout can also be turned round to reposition where you want steam to go. Massive water tank. 2 carry handles making filling and putting on unit a breeze. Like the blue glow it gives off. Lovely neat unit.

Rated 5 out of 5 by from Very effective Central heating made the air far too dry in our large living room - eyes and face become uncomfortable. Solved by this humidifier even when on low - and the large tank means it can be left on all day. We have a hygrometer and to be honest there has not been a dramatic change to humidity reading - but enough to increase comfort. It took me a while to work out how to fill the tank (instructions omit this). Just lift the clear plastic tank off the base, turn it upside down, unscrew the large knurled knob with your fingers and lift out, fill tank with soft tap water, reassemble and turn it on.

Can this device be turned on and off from the mains or does it have a standby switch? i want to connect to a humidistat which turns it on and off once it reaches a required humidity level.

Yes, I am pleased to advise the product will support this.

Unfortunately, max output per hour is not provided. The system has no limit on the run time provided it still has water in it.
