The details

Homeowners who live in an overly dry or cold region can benefit from investing in large-sized humidifiers.

Such units come with massive water tanks and offer generous run times. If you sail in this boat, one model that you can look into is Elechomes HS8820. Its water tank has a 5.5L capacity and the unit provides a steady operation for up to 55 hours. Here are more details about this unit.


Elechomes SH8820 has cutting-edge features, which is why it’s a favorite for many homeowners. Starting with the design, this unit is available in two color options: black and white.

While not everyone will be pleased with its angular design, the humidifier will blend perfectly in a contemporary-themed space.

Another point worth noting entails its top fill design. This makes it incredibly easy to refill without making a mess of it.

The SH8820 model is designed to emit either a cool or warm mist. Thanks to this feature, you’ll be able to use it all year long by adjusting the settings depending on the weather.

This humidifier employs a complex ultrasonic mist technology, resulting in a very quiet operation. It operates so quietly that you won’t even notice that it’s at work.

Ease of use

Humidifiers are a cinch to operate, and the Elechomes SH8820 is not any different. The first step is to flip the tank’s lid open so that you can fill it with water. Once it’s filled to the brim, all you need to do is plug it to an outlet and turn it on.

One thing you’ll need to keep in mind is that the manufacturer recommends using the humidifier with soft water. If you live in an area with hard water, then consider distilling it first. The alternative to this is to invest in an optional water filter.

In addition to this, the unit arrives fitted with an anti-scale pad at its bottom. There’s als a spare one in the box, and they help to reduce the accumulation of lime scale. To keep the humidifier working effectively, be sure to clean this pad once every three months.

Elechomes SH8820 sports a very intuitive design. All the controls are positioned on the front for easy access. Better yet, you can navigate it from a far as it also comes with a remote containing the same controls.


Undoubtedly, the key highlight of this humidifier is its 5.5L water tank. This is above standard size as most humidifiers usually come with 1.5 to 2.5L water tanks.

With a large water tank, you won’t have to refill the unit every other time. This makes it the perfect humidifier to set up in a large space. Just to put things into perspective, it’s designed to offer a coverage ranging from 430 to 755 ft². And the best part is, it has an extensive runtime of up to 55 hours.


Elechomes HS8820 is among the most expensive humidifiers. But given the kind of features it offers, there’s no question that you’ll be getting significant value for your money.

The unit includes advanced features like cool/warm mist settings, a remote, timer, 20dB noise level, auto shut-off among others. So if you’re willing to splurge, this humidifier is an excellent buy.
