A Bristol inventor is causing a stir in home cooling - and big air-con brands are not happy

Bristol — What began as a frustrating experiment in a small British garage has now become one of the country’s fastest-selling cooling devices. The idea is simple: a compact, portable unit that helps cool any room in under two minutes — with real cooling power at a fraction of the usual cost.

That is exactly what Thomas Barker, a 54-year-old aerospace engineer from Bristol, asked himself when he saw the price tags in his local DIY store.

“A decent window air conditioner costs around £700. A portable air conditioner can cost even more. Then you are paying £170 to £260 a month just to run it during a heatwave. I kept thinking — there has to be a smarter way.”

With more than ten years of experience developing thermal control systems for aerospace — the technology that helps protect satellite instruments from overheating in orbit — Thomas had the technical background to do something about it.

“The concept is not complicated,” says Barker. “The air is already in your room. The key is to pull in the warm air, cool it quickly and push it back out — without a compressor, without refrigerant and without the punishing running costs.”

After several months building prototypes in his garage — testing different airflow configurations and cooling chamber shapes using the same thermal principles he had worked with throughout his career — he built a working prototype.

Real cooling power in any room in under two minutes — without bulky equipment, refrigerant or expensive installation.

“I put the prototype in my living room when it was 34°C and pressed the button,” Barker recalls. “Within two minutes the thermometer showed 17°C. I tested it four more times just to make sure.”

“My neighbour came round — he is a retired air-conditioning technician with 35 years of experience. He walked into the room, checked the thermometer, looked at the device and suddenly went quiet. Then he asked how quickly he could get one himself.”

Not long after, everyone on the street wanted one. That prototype became AirZuma.

What began as a personal engineering challenge eventually became AirZuma — a patented portable cooling device now used in more than 60,000 homes across the UK.

Helps cool a room from 34°C to 17°C in less than 2 minutes — tested, repeatable, reliable
Uses up to 90% less electricity than a window air conditioner — runs for hours with minimal energy use.
No installation required — just plug it in and press one button. Ready in 30 seconds.
Whisper-quiet under 40 decibels — quieter than a library, easy to run while sleeping
Fully portable at under one kilogram — move it from the bedroom to the office, caravan or garden room with ease

AirZuma was made for anyone who wants to:

- Cool a bedroom, lounge or home office without fitted air conditioning
- Stop paying £170–£260 a month just to keep the house comfortable
- Get real cooling power in rented homes where window air conditioners are not allowed
- Keep older parents or young children comfortable without running a central system
- Enjoy portable cooling in caravans, garages, garden rooms or covered outdoor spaces

With warmer spells arriving earlier and UK heatwaves becoming harder to ignore, demand for AirZuma is rising fast.

“We can barely keep up with production,” Barker admits.

The problem: as a small UK-led operation, Barker cannot manufacture unlimited quantities.

“Right now we have roughly 3,200 units left in stock. Once they are gone, the next shipment is at least 8 weeks away.”

“I own a Frigidaire window air conditioner that cost me £1,150. On 90% of nights, AirZuma cools my bedroom just as well — and I do not have to wait 45 minutes for the room to cool down. My electricity bill dropped by £100 last month.”

“My neighbour walked into my lounge and asked if I had finally had proper air con fitted. I had not. I showed her AirZuma. She ordered one before she left. The next morning she texted me: first full night’s sleep in three weeks.”

“I bought it for my 79-year-old dad, who refused to run his old air conditioner because of the electricity cost. The next morning he called me and said it was the coolest night he had had in years. Worth every penny.”

Order today and you can get AirZuma at the introductory price of under £100 — nearly half the regular retail price. This limited-time offer applies only to the current production batch.

⚠ Warning: Once stock runs out, the promotion ends immediately. Based on last year’s rush, AirZuma sold out before midday.

UPDATE: Demand for AirZuma has increased sharply and stock is moving faster than expected. Order now with 60% off before this batch is gone.
