The Crystal air conditioner from EcoAir is a powerful, compact model designed to offer around 9000 BTU in terms of cooling capacity. This translates to efficient cooling in spaces under 25 square meters. Despite being smaller and lighter, this particular unit comes fully equipped with all the bells and whistles you’re likely to find in a high end portable air conditioner.

There’s nothing more frustrating that trying to work in a sweltering office or catch some sleep in a muggy, humid bedroom. Featuring a decent cooling capacity and 3 in 1 multi-functionality, the EcoAir CRYSTAL Portable Air Conditioner works as a fan, air filter and dehumidifier.

What Are You Buying?

The UK isn’t exactly a hot place; in fact, it’s actually cold most of the year. But when the heat wave strikes, even the best and biggest fans simply won’t cut it. This is when you need a portable air conditioner with a few tricks up its sleeve. Designed to be slick and non-intrusive, the EcoAir CRYSTAL Portable Air Conditioning offers an ideal cooling solution without having to spend a lot of money on AC bills.

Like most portable air conditioners in its class, the Crystal from Ecoair performs more than one function. It can work as an air filter, cool your home and dehumidify it all at the same time. The manufacturer incorporated a cooling capacity of 9000 BTU which is average for a unit of this size. This capacity is more than enough to effectively cool a room up to 25 square meters.

The dehumidifier can also be used independent of the air conditioning function so you can dehumidify without having to cool the room. It can extract up to 24 liters of excess moisture and humidity every day and get rid of it automatically courtesy of the evaporating function. And thanks to anti- mildew technology in the fan, your unit actually dries itself after use to prevent odors and extend the conditioners lifespan. EcoAir also included an air filter which improves air quality by reducing unwanted particles and dust in the air. 

Despite all these capabilities, the Crystal portable AC only consumes around 1Kw an hour. Now, while the unit does not use R280 refrigerant which is the most environmentally friendly gas, it uses an alternative which is pretty close. The EcoAir CRYSTAL Portable Air Conditioner uses a low GWP refrigerant known as R32. R32 was introduced as part of the EU’s commitment to cutting down CO2 emissions from these products making your AC that much more eco-friendly.

How Easy Is It To Use?

Like most of the smaller portable air conditioners, the Crystal is as easy to use as it gets. Setting her up is effortless while the controls are incredibly intuitive. Still, Ecoair included a user manual to make things easier. Starting at the weight and dimensions, this compact unit only weighs 26.5Kg. This allows it to be non-intrusive as well as easy to move around. The mobility is further aided by easy glide castor wheels so you don’t have to lift it.

But how exactly does this air conditioner make life easier? There are definitely a lot of bells and whistles attached to the Crystal. I’ll be the first to admit that the control panel can get a bit confusing what with all the different functions.

However, EcoAir made a valiant attempt to make things highly user friendly. For one, there’s an LED digital display so you can see exactly what you’re doing. And if you don’t want to bother with trips to and from the control panel, there a smart remote control included to operate your AC from the comfort of your couch. Note that the remote also has its own digital display.

The Crystal AC is also highly energy efficient with a Class A energy rating despite being chock full of features. And speaking of features, a lot of them are designed to make the portable AC as autonomous and independent as possible. For instance, the unit has a self-evaporating system to clear any collected humidity as well as an anti-mildew function to prevent mould and bring down maintenance/ cleaning requirements.

Anything Else You Should Know

Looking at most portable air conditioners, venting always seems to be the main problem. Unfortunately, the EcoAir CRYSTAL Portable Air Conditioner is no different. The unit performs relatively well on all other fronts except the window mounting. It’s more or less useless unless you have vertical sliding windows.

But for the rest of us with normal windows, it’s going to take some cardboard, duct tape, and innovating to craft a decent seal and prevent hot air from coming back into the room. Ecoair could have done a much better job here; even adding to the length of the hose would have made a huge difference. No matter; there are plenty of affordable window venting kits available that will allow the Crystal to achieve full potential.


Designed to be slick, compact, and non-intrusive, the Crystal portable unit from EcoAir offers a whole new way to condition the air.  Despite being small in stature, the air conditioner packs an incredible punch with an array of features that would put some high end ACs to shame. In addition to incorporating the latest in cooling technology, the Crystal boasts of quite the impressive range of user friendly features. From a 3 in 1 multifunction all the way to a handy remote control, the Crystal truly is the AC for the modern homeowner on the go.
