I have disautonomia, which means my body cannot regulate its temperature well. I suffer a lot in extreme heat and humidity, and this summer, my sleep has been completely shot.
That’s why I took the plunge and bought an affordable Euhomy BTU portable air conditioner unit, available from Amazon right now for $206, for my bedroom, as I don’t have AC in my home.
It has proven to be a fantastic way to not only cool my bedroom, but wick away the heat and moisture from my entire second floor.
Why a portable AC unit is absolutely worth every cent
It has a two-meter (6ft) hose, simple operation, and a remote control for convenience. It cools down my primary bedroom in the time it takes me to brush my teeth, wicking away extreme heat and humidity in minutes. I couldn't be happier with this purchase.
The unit is fairly heavy but compact, measuring 11.4"D x 12"W x 26.7"H, and fits nicely in the corner of my bedroom. It does need a couple of feet of clearance on either side and if it has been tipped during transport or installation, leave it standing for 24 hours before plugging it in and using it.
I have popped the long hose out of the window, and though the instructions say the metal window adapter is for slide windows only, I’ve easily fandangled it to stay put with my push-pull window.
It’s not budged since I set it up a few weeks ago to keep my bedroom cool during a heatwave, and I simply closed the triangular gap at the bottom with an old, clean towel.
This portable AC unit takes my bedroom from 82° Fahrenheit to 64°F in under 10 minutes and not only keeps it icy cool and low humidity all night, it wicks away the heat in my other two bedrooms and bathrooms, too.
It won’t make my daughter’s room, which gets all the sun in the late afternoon and early evening, as icy cold as mine, but it makes it comfortable to sleep in without issue, and she doesn’t even need a fan.
The 10,000 BTU is said by the manufacturer to cool up to 450 square feet, so that tracks, as my upper floor is around 250 square feet or so.
The Euhomy portable AC unit has been so effective in my home that if it’s running for an hour upstairs, it cools not only my upper floor, but the cool air drops down the stairs and makes the living room comfortable too, making the square footage cooling estimate very accurate.
The only trade-off for the comfort is that the unit is a bit noisier than my brilliant tower fans, though I’ve fallen asleep in the blissful cool of the AC and not been that bothered.
I do, however, wear earplugs on the nights when I am very tired or in pain and more sensitive to sound than usual. It’s no hardship as I wear soft but very effective soft, noise-cancelling silicone earplugs from Amazon.
The portable AC unit's ‘low’ AC speed, is more than adequate for cooling, but the volume of the portable AC unit in my bedroom, at my pillow, is between 50-55dB, the equivalent, my DecibelX app says, to a mechanical fan, for context.
My verdict
Amazon shoppers love it as much as I do, rating it highly and singing its praises. Verified shopper Damion calls it 'small but mighty' and I couldn't agree more.
I suffer from chronic health issues and extreme heat and humidity are my nemesis. I wear the Visible Band to track my illness and how much fatigue I suffer as a result, and for three months before getting the portable AC unit, my HRV (heart rate variability, a scientific indicator of how stable my body is), was showing as ‘poor’ and ‘out of balance,’ trending away from a healthy baseline every morning,
Every morning since I have been using the portable AC unit in my bedroom overnight, my HRV has been tracking as stable and good.
It’s shown me how much the extreme heat and humidity was negatively impacting my wellbeing, making this my favorite purchase of 2025.
I am actually blown away but the difference this portable AC unit is making to my wellbeing, and the comfort of my family. It’s a quarter of the size of the one my parents bought at Costco when I was a teenager, and half the price, despite being much more efficient at cooling, so the technology of these units have really come along in the last 20 years.
I’ll be buying another one for the first floor of my home as soon as payday hits!
What to shop
For bigger areas, and especially if you have taller ceilings, getting a higher BTU AC unit will serve you well to allow the device to cool up to 550 square feet quickly and efficiently.
Save yourself a bit more by dropping down to the 8000 BTU version of my portable AC unit. This will put the chill on 350 square feet.
Once my room is adequately cool, or when it’s not quite hot enough for the portable AC, I use my tower fan. They are excellent, quiet, and much better than a classic mechanical fan. You can programme this to switch off overnight.
That exhaustion you feel on hot days is often dehydration in disguise. Electrolytes are imperative for all during hot weather to help you adequately replenish the ones you lose from sweating in extreme heat and humidity.
My husband immediately got one of my vacuum-insulated water bottles when he saw how excellent mine is. It keeps my ice water cold for 12 hours. The flip-down straw and lid combo makes it completely leakproof, and I am obsessed with it. My daughter has one too now and we all give it a 5/5 stars as the best water bottle any of us has ever had.
Stop the heat from getting in at all with a handy portable blackout blind. I have used this one for nearly a decade to keep the heat and glare of the sun out of my home’s hottest rooms. It suctions on and off without damage and packs away in seconds for easy, light traveling.
