In practice, all of these humidifiers will raise the indoor humidity but we found cool mist humidifiers to be the best option on the market. In our testing, cool mist humidifiers were far less energy demanding than warm mist (avg. 40 watts cool vs 260 watts warm), and considerably easier to clean. Benefits of Using a Humidifier There are lots of factors you'll want to consider when buying a humidifier, most importantly: how often will you be using it and for what purpose? Whether you're looking for a machine to humidify a large room or a smaller version for your desk at work, the capacity, runtime and square footage will tell you everything you need to know. Most humidifiers on this list hold around a gallon of water in their water tank and runtimes range from 6 to 70 hours. If you're looking for a machine that you can leave on all day every day with minimal refills, then you'll want the one with a higher runtime and capacity most likely. But if you're just looking for a humidifier to get you through the night, a smaller capacity and runtime may be okay, especially if it means a lower price point. The square footage a certain model is able to cover will also tell you if it will work in the space you have in mind because, like air purifiers, humidifiers work best in small, enclosed spaces.
We also like the aromatherapy option on this humidifier. We added six drops of strongly-scented tea tree oil to the aroma pad and enjoyed the lightly-scented air in our room an hour later. Note that six drops is more than the recommended 2-3 drops. This Dyson humidifier is a great investment piece, especially as it doubles as a fan, which means that in the summer months it won’t sit dormant. There’s no oscillation feature, but you can manually adjust the angle of the air outlet – be careful if you’re doing this when the humidifier is on Heat mode, since the output can be very hot. Finally, you can use the aromatherapy pad to add essential oils to make your room smell nice. Elechomes 5.5L Large Room Humidifier SH8820 performance – Quiet and effective, but it only just copes with its maximum rated room size This humidifier performs well. In our at-home testing, it reached up to 63% humidity on its highest level, while on the lowest level it reached up to 53%. As its two water tanks are so large, it can also run continuously for 24 hours on its lowest setting before needing to be filled up again.

In addition, there are controls for managing humidity output. First, you can set the output level, which at maximum is capable of outputting 600ml per hour, giving nine hours of runtime on a full tank; on minimum output, you can get up to 40 hours. This model also has a fragrance dispenser for essential oils though this writer found it difficult to detect the scent beyond the actual vapour trail; even with my face in it, the scent was extremely subtle. In other words, don’t expect your room to be infused with a scent of jasmine unless, perhaps, your home is already clinically clean and completely free of odours – and that means no pets! Finally, humidifiers are also great for keeping expensive floorboards and delicate wooden instruments like acoustic guitars and violins in tip top shape. Different types of humidifiers
Second, you can turn on the Heat mode, choosing from three levels. Heating the water brings two benefits: it kills bacteria and it pushes warm water into the air, making it more comfortable during the winter months.
The Elechomes HTJ-2119 Ultrasonic Humidifier requires virtually no setup. After opening the box, you simply need to fill the tank, plug in the base, and place the water tank and the nozzle on top. The front of the humidifier is home to all the controls, which are duplicated on the thin remote control that comes with the appliance. Although the controls all have an icon, they’re neatly labelled in English, too, leaving no doubt over the function of each button. We start by noting the humidity level of a closed room. We fill each humidifier’s tank to the maximum and let it run on the highest setting (also noting how long it takes to empty the tank). While the machine is running, we measure the noise level of the machine in decibels. After an hour, we measure and take note of the humidity level in the room. This is repeated at the two hour mark, or when the tank is empty. This process is repeated for each mode the unit has, such as lower mode and night mode. The highest mist setting can raise the humidity levels in a medium sized room up to 69% in just under an hour, while the humidity target can be adjusted so you never feel uncomfortable with the humidity levels in the room. However, be careful that the water doesn’t leak on the highest setting - our reviewer had a pool of water escape when it was tested. The aroma pad is also a nice extra, enabling you to add essential oils to the pad that the humidifier then emits with the mist, giving an extra scent to the air. If you live in a hard water area, Elechomes recommends that you use distilled water in the humidifier, or you can buy an optional water filter. Furthermore, there’s an anti-scale pad in the bottom of the machine, and a spare one in the box, which helps to prevent the build up of limescale. This should be cleaned every three months or so.
As a smaller model, it’s ultra-quiet but is capable of holding a large amount of water, which means that it can run for up to 36 hours. This humidifier is easy to clean and its humidity levels perform well on both the high and middle mist setting, climbing to a 68% level within two hours on the highest setting. Another quiet model, it will last for 19 hours on a high setting, but 60 on a lower setting. However, the built-in humidity sensor is quite sensitive and the model does need to be cleaned regularly to avoid bacteria getting into the water.There are two main types of humidifier: ultrasonic and evaporator. Ultrasonic models use a vibrating diaphragm that agitates water droplets which are then blown out of the unit by a fan. These machines tend to produce a fog-like mist that is clearly visible. However, they also tend to leave a very fine layer of white calcium dust on furnishings, unless, of course, you use expensive distilled water. Unlike the Dyson and Philips models above, you’ll have no problem seeing the mist coming out of the Eva because it creates more vapour than Strokkur Geysir. In fact, at full bore it produces a plume nearly a metre high that spreads to a width of around 40cm at its highest point, so there’s no question of you wondering whether it’s working properly. Elechomes 5.5L Large Room Humidifier SH8820 design and features – Simple and easy to use, it does what you need it to Using the humidifier in a large room (742 square feet), I found that the SH8220 was pushed to its limit. It was slow to raise humidity from the 42% starting point to my set level of 55%, taking a few hours. However, use this humidifier in a smaller room – your average living room or bedroom, for example – and it will cope exceptionally well. In our testing, the most important feature of a humidifier was a humidistat — basically a thermostat but for humidity — that monitored the active humidity. When left untouched, cheaper humidifier models with simple on-and-off control often raised the humidity far above the 60% maximum recommendation, leading to condensation on interior windows and surfaces in the room.
The Elechomes SH8820 is an excellent value ultrasonic humidifier that comes with a full gamut of features. At 26.5cm x 18cm x 30.5cm, this humidifier is a perfect size for both floor or desktop use. We especially like its simple Apple-esque styling, the clearly etched lettering on the touch sensitive control panel, the ingeniously simple uni-directional vapour spout with integral aroma diffuser, and the way you can fill its ample 5.5-litre water tank without having to lift it out. Small wonder it’s one of the most popular humidifiers in the USA.You should empty the tank of the humidifier, wipe all of the surfaces dry and refill the water in portable humidifiers daily. This will help to reduce the growth of microorganisms. Reviewers who were less impressed with this humidifier noticed water pooling around the humidifier, as our tester did. "The humidifier releases it's mist from the top of the device and the water will pool around the nozzle and drip down the side of the humidifier and leak everywhere", said one reviewer. Other complaints were that the handle is too small to lift and carry the water tank comfortably, and that the display lights are too bright at night. Should you buy the Elechomes HTJ-2119 Ultrasonic Humidifier? Despite its diminutive size, the Elechomes is designed for large rooms up to 70 square metres. In our tests it spewed out a huge metre-long plume of clearly visible mist from its two adjustable ports which can be aimed in any direction. Also, its built-in humidistat displayed the same percentage of humidity as our nearby hygrometer so its accuracy is clearly spot on. This means that if your room has a humidity reading of about 35% and you set the Elechomes’ target value to 45%, you can safely bet it’ll continue emitting vapour until the room reaches that value. It also features three volume levels of vapour and three heat settings for winter use. The addition of a remote control can be considered a bonus.. The Elechomes HTJ-2119 Ultrasonic Humidifier is an excellent option if you want a humidifier with extra features but don’t have the budget or space for larger, more expensive models. We like that this humidifier has a big water tank for its size, even though it's smaller than other models. Running continuously on the highest setting, the water tank didn’t run out of water for 12 hours. One of the best things about this Dyson Humidifier is that before the water gets vaporized it purifies the water - getting rid of bacteria and minerals with its ultraviolet light. This is one of its best qualities, especially for those who are worried about the air quality in their house. It’s easy to refill the water and our tester found that it ran continuously for 12 hours before it needed to be refilled. This model is better for smaller rooms up to 172 square feet.
