Challenge 6 Litre Portable Air Cooler Fan - White

Product Information

We found the the best bet is to run the air con unit in a bedroom for a few hours before you want to go to sleep, and then turn it off once you turn in for the night. A stylish mobile air conditioner that offers 3-in-1 functionality, WiFi connectivity, and comes with remote control and window kit included, the Duux North 9K Smart Air Conditioner promises a lot. And so it should with a price tag that's double the most affordable air conditioners in our round-up.

However, a higher BTU also means a higher price tag, and likely higher running costs, so it's a balancing act of investing as much as you can for better performance against how much you're willing to pay upfront for a unit. Room size Beyond that, this air con unit is bulky and heavy. It weighs in at 31.5kg, one of the heaviest units we've tested, so carrying it upstairs is a definite two (strong) person job. But, it looks good. And its curved front, minimal design, and gloss finish all make it far more unobtrusive in a room than you might expect. The build quality is also solid and robust. The unit performed solidly during our testing, reducing the temperature in the room by 2°C in 10 minutes. Like most air con units it isn't silent, there's 51-53dB of noise depending on if you opt for the low or high cooling setting, but it's a downside our testers were happy to accept in return for its temperature-reducing powers. A portable air con unit uses both a fan and a compressor to cool the air, and that's a noisy process, meaning you're likely to have to turn the TV up quite a few notches if you have one running in a living space. And, if you're a light sleeper, then you may struggle to sleep whilst the air con unit is running. As an electrical appliance, portable air conditioners will cost money to run, with larger and more powerful units (that means a higher BTU) generally using more energy than smaller units.

Frequently Asked Questions

It also comes with a remote control and two window kits included, a timer function, 'night' mode for (slightly) quieter night-time operation, plus 3-in-1 air con, fan and dehumidifier functionality. Personally, we'd sacrifice some chill (and save a lot of cash) and opt for the Duux Whisper Flex Ultimate Fan over the North Smart every time. Especially if you're looking for ways to keep a bedroom cool as the fan's silent operation won't disturb your sleep. Whilst the fan won't actively lower the room temperature like the North Smart can, all those who've tested the Duux Whisper Fan now swear by it's oh-so-silent 'natural-feeling' breeze, reaching for it as a go-to sleep aid whenever the mercury soars. You might also want to consider whether you want your portable air conditioner to come with a timer, remote control, or WiFi connectivity. With some air coolers, there’s a risk of adding to the room’s humidity, which can be a problem if it already suffers from excess humidity. Plus, where water tanks are open inside the cooler, there’s also a risk of spillage – which can be a worry if you’re using a desktop model plugged into your laptop or PC. As far as features go, the Honeywell keeps things simple. One dial switches between off and the three fan settings, while the other selects cooling, oscillation or cooling and oscillation. What matters more is that it dishes out a consistently good, cooling airflow, with the louvres shifting side to side to spread it over a wider area. You’ll still need to clean the honeycomb cooling membrane regularly to avoid unpleasant smells, but if you’re keener on keeping cool than faffing around with modes and features, this is the air cooler to buy.

The first thing you'll want to consider when choosing the best portable air conditioner for your home is BTU. Most portable air con units come with an energy rating stated on their energy label to help you compare how many kW per hour the unit will use. How we test portable air conditioners The 7000BTU air conditioner's 20.5kg weight, whilst not insignificant, makes it far lighter the 30kg average, and means this unit is much easier to move around the home than most. Plus, its 780W power consumption is one of the lowest of all the air con units we've tested, meaning it offers lower running costs too.

We also like the fact that you can clean the filter under the tap or in the dishwasher, and that the illuminated side panels can be set to glow with a choice of seven colours if you fancy a little mood lighting. While it could be easier to remove the filter and get the water tanks in and out of place, for sheer value and convenience, this cut-price compact cooler is a winner.

This has the effect of dramatically reducing the temperature in the room. In our tests, we found the best portable air conditioners, used in a well-sealed room, could reduce the temperature by up to 10 degrees in under an hour. The Russell Hobbs RHPAC11001 can do just that, offering 4-in-1 use thanks to air con, fan, dehumidifier, and heater functionality. Depending on your needs that could mean it offers better value for money, as it will be useful all year round, keeping your space cool in the summer as well as warm in the winter. In an ideal world, all of our homes would be better insulated and able to remain cool in the summer without the additional energy use or expense of an air conditioner.However, for many of us this isn't the reality, and if you struggle to keep your home at a bearable temperature during the summer months, then a portable air con unit could help. So whilst the best fans definitely work to cool a person thanks to the breeze they create that does a surprisingly good job of cooling the skin, only an air conditioner can dramatically lower the temperature of an entire room or living space. And only an air conditioner will deliver that fridge-like cold air we all crave in a heatwave. Do portable air conditioners cost a lot to run? Very often an air con unit will come with additional functionality, usually a fan setting and dehumidifier function. More expensive portable air conditioners sometimes also feature a heater function that means you're more likely to be able to get year-round use out of your investment.In terms of cooling powers this is one of the most powerful portable air con units we've tested, but, that power does comes at a price, with the AEG Comfort 6000 using 3400W of energy compared to the MeacoCool MC Series 7000BTU units 780W. It means running costs for the AEG are higher – as is the initial outlay compared to the Meaco – but, our reviewer did find they didn't need this unit running for as long to cool down a space. Relatively affordable, lightweight and compact, energy efficient and easy to use, there's a lot to love about the MeacoCool MS Series portable air conditioners. Which is why we think they're the best portable air conditioner to invest in if you're looking for an affordable all-rounder. It also offers some good functionality, including air con, heater, and dehumidify functions that enable year-round use, plus a timer, 'night' mode, remote control, and WiFi connectivity. It's generally recommended to close doors and windows in the room that you're trying to keep cool, so if you only want to keep a small bedroom cool then you can opt for a cheaper lower BTU unit, however an open plan space will require a much more powerful appliance with a larger BTU. Portability

You're likely opting for a portable air con unit because you would like it to be... portable! However, in reality, even the best portable air conditioners are both bulky and heavy, weighing from 20kgs for a smaller 'lightweight' air conditioner to 30kgs+ for more powerful units. While some of the water is recirculated through the system, some will inevitably leave the cooler in the air blown out by the fan. Because of this – and the fact that the water in the absorbent pad or membrane can grow stale – you need to keep the air cooler filled and change the water in the tank daily. You should also wash the pad or membrane occasionally or you might get some pretty nasty smells. Is there anything worth looking out for? That said, it's important to buy the best portable air conditioner for your room size, otherwise your unit will be working overtime to try and cool a too-large space.If you're spending this much on an appliance – and one that's going to take up a good deal of storage space in the home – then you might want it to do more than just cool. It has some downsides, but only in keeping with most portable air con units, in that it's heavy which makes it not quite as portable in reality as its name may suggest.However, the build quality is good, it has easy-to-use controls, and its design is unobtrusive – although we think the AEG Comfort just pips it to the post in the style stakes by offering a sleeker design.
