Elechomes SH8820 Ultrasonic Top Fill Humidifier Review

Dry air can be a major source of discomfort. Nobody wants to wake up in the morning feeling like they’ve just spent the night in the Sahara desert. This can be especially irritating in the winter time, due to relative humidity. Basically, the colder the air is, the less moisture it can hold. So, air that’s 100 percent humid at 20 degrees will be fully saturated, misty, and snow will be swirling. But if that air gets heated up to 70 degrees (for example, in your furnace), the relative humidity will drop to 16 percent, which is dry enough to cause significant discomfort.

For this reason, a humidifier isn’t just important in dry climates. It’s equally important any time the outdoor temperature drops below freezing. To help you out, we’ll be reviewing theElechomes Ultrasonic Top Fill Humidifier, model SH8820. In many ways, it’s similar to their previous offering, the UC5501. However, there are a few significant upgrades that make the SH8820 shine all on its own.

Overall Design

在我们进入更高级的功能之前，让我们来看看整体设计。与大量的加湿器不同，这可以看起来是架子上的，SH8820有一个干净，白色的设计，将在高端电子商店中看起来正确。前面板显示电流湿度水平，具有明亮的LED灯，易于从房间内清晰地阅读。Underneath the display, you’ll find eight soft touch buttons which can be used to turn the unit on and off, set the humidity level, select maximum or minimum power levels, set a timer, activate sleep mode, switch between hot and cold humidity, and activate the child lock.

在屏幕后面，有一个可拆卸的5.5升坦克，易于填充，同样容易在必要时清洁。为此，您需要拆下具有一对可调圆形喷嘴的单元的顶部。外喷嘴是内喷嘴外部的环，所以它们两个都可以独立旋转，以指示您希望它的薄雾。

In addition, you’ll also receive an infrared remote, which has all the same functions as the front control panel. The remote has a slim, compact design that’s easy to slip into your pants pocket. Because it’s infrared, it’s line of sight only, similar to a TV remote. Overall, the range is about 15 feet, which isn’t enough to operate from across the house, but it’s more than sufficient to control across the room from your bed or sofa.

Of course, humidity isn’t the only factor that will affect your comfort inside your home. Good temperature is also an important part of the equation. TheEcobee 4是一个功能强大的智能恒温器，可通过Amazon Alexa或Companion应用程序操作。

日常运作

在日常的基础上，SH8820易于使用。操作的最简单方法只是自动设置湿度水平。使用此功能，您只需设置您的首选湿度水平，SH8820将休息。按下湿度按钮时，LED显示屏将暂时停止显示当前湿度水平，然后显示您将其设置为的级别。反复击中按钮将以5％的增量调整设置，从50％到100％。在5秒的不活动之后，显示屏将切换回显示当前湿度水平，如果湿度降至您将其设置为的级别以下，则加湿器将自动启动。

In addition to allowing you to set the desired humidity level, you can also switch between three different power levels. The lower settings can be either warm or cool, but the highest, most powerful setting works on warm mist only. We’ll talk about the difference between a warm and cool humidifying in the next section. At the highest setting, the SH8820 is rated to treat 750 square feet of air. This is enough to keep a small apartment humidified all on its own, and more than enough for even a large bedroom in a large house, or a spacious living room. Obviously, your mileage will vary depending on how much air circulates throughout your house.

另一种方法可以控制SH8820是设置过夜定时器。定时器可以在1小时到12小时的任何位置设置，只要定时器打开，加湿器就会连续运行。如果您只想在一夜之间运行SH8820，这是一种简单的方法。除非拔下加湿器或更改设置，否则定时器将在每晚同时激活加湿器。无论您使用哪种操作方法，风扇将在加湿器关闭以清除机构中的任何残留水分后，风扇将继续运行3分钟，防止模具生长。

SH8820上的罐具有5.5升容量。从理论上讲，这足够了40小时的连续操作，但是如果您在其最低设置上运行加湿器时才才是如此。在最高的环境中，您正在观看12到15个小时，这仍然足够了两晚。这仍然比你从大多数加湿器从大多数加湿器中看到的容量显着更多，这往往有2到3升的能力。无论如何，SH8820的传感器将检测罐何时空，并且会自动关闭加湿器以防止任何损坏。

This humidifier is very quiet. It runs at 32 dB, which is only slightly louder than a whisper. Again, this is on the lowest setting, but even on the highest setting it’s quiet enough that you won’t need to turn up your TV or raise your voice during normal conversation. The SH8820 is also quieter when it’s running on cool mist as opposed to warm mist, since the heating element causes a louder rushing noise due to increased airflow.

如果你有你的加湿器设置为自动模式e, it’s going to be running both night and day. So, maybe you want it to run on full power, but not when you’re sleeping. In that case, simply press the sleep button on the front panel or the remote. This will limit the SH8820 to low power mode, and will also deactivate the front LED. You can also use the “Screen-off” button to turn off the front display at any time, which will save a small amount of power.

Runs Warm or Cool

We’ve already mentioned that the SH8820 works both as a warm or a cool humidifier. But what’s the difference between these two settings? We’re about to break it down.

首先，温暖的加湿器首先加热水以释放蒸汽。这允许更快地释放水分，因为温热的蒸汽比凉爽的雾更容易吸入空气中。

It’s also very soothing if you’ve got a cold or a sinus infection. Just put your face near the top of the unit – but not too close! – and breathe in. This can provide a lot of relief. However, it’s important to remember that a warm humidifier works by heating the water to a boil. If you have children or pets, you’ll need to make sure this type of humidifier is out of reach for their safety.

冷雾喷雾增湿器工作的水,similar to a perfume atomizer. Traditional designs suffer from a drawback, though; they’re prone to mold growth, which means they require frequent maintenance in order to keep them clean. However, the SH8820 is a newer, ultrasonic design which works a little bit differently. Instead of pushing the water through an atomizer, a vibrating plate in the bottom of the tank moves at ultrasonic speeds, vibrating the individual water molecules until they escape the surface, much as they do when water boils. Because cool mist mode does not require the fan to run at high speeds, the machine will run much more quietly in this mode. However, there’s a limit to how much moisture you can put out in this mode, so it only works for the two lower intensity settings.

维护要求

Some humidifiers can be difficult to clean, since you’ll often have to perform frequent descaling. With the SH8820, the majority of the cleaning is very easy. The tank has a flip-up handle for easy removal, so you can even wash it in the dishwasher – top rack only – if you don’t want to clean it by hand.

That said, as with all humidifiers, scales can build up on the heating element if you’re running it in warm air mode. You can clean them with a decalcifier like CLR, but this is still a headache. To ensure that you have to do this as little as possible, you should only fill your humidifier with soft water. In the event that your home has hard water, the best course of action is simply to fill your tank with distilled water, which has no mineral content to form scales. Alternatively, Elechomes sells a filter that can remove minerals before they have a chance to build up.

To further improve your indoor air quality, a dedicated air filter can make all the difference. In this case, theBulex HEPA Air Purifier是一个很好的选择。这种强大的单位将过滤颗粒，气味和其他污染物，因此您可以更轻松地呼吸。

Final Verdict

如果您过去拥有加湿器或两个，您可能习惯于希望有一些额外的功能。我们留下了深刻的印象Elechomes SH8820because it does just about everything. Obviously, the best feature is that it can run warm or cool, since this gives you plenty of options.

However, there’s a lot more to love. The automatic mode makes it as easy to operate as your thermostat, while the sleep mode gives you dark, quiet operation overnight. And the large tank means you won’t have to refill it every single day. All in all, the SH8820 is a great value, and well worth buying.
