I would have given it 4.5 stars if that option existed, not because it’s failed us, but because it has a few quirks. More on those in a moment.The reality of evaporative cooling in the UKFirst, the science. Evaporative cooling works brilliantly in hot, dry climates – if incoming humidity is around 20%, you could see a temperature drop of roughly 10°C. But here in the UK, daytime humidity rarely drops below 30–40%, and at night it often sits at 60–80%. In those conditions, expect a more modest drop of about 4–5°C.That said, in our reasonably sized double bedroom, we’ve both slept comfortably with it running on the humidification setting at mid-fan speed. We followed the instructions carefully: bedroom window slightly open, bedroom door open too. That cross-flow is essential to stop the room from becoming overly humid, and we haven’t found that to be an issue at all – I put that down to the natural airflow from the open window.The "fiddly" bit – the water reservoirThis is where the design gets a little tricky. The reservoir is a slide-in drawer in the base, holding about 4 litres of water. Attached to the bottom is a small pump with a hose and electrical cable, which sends a steady trickle of water up to the cooling plate at the top.You can pull the drawer out part-way, but the flexible pipe stops it from coming all the way out. To fully detach it, you have to reach into the bottom of the drawer, unclip the pump unit, and then carry the whole drawer to the tap. The problems? 4 litres is heavy, the drawer is bulky and doesn’t fit under every tap, and refitting the pump means submerging your hands to clip it back into place – all possible, but undeniably fiddly.My solution – and I stole this from another reviewer – was to buy a simple 2-litre plastic kitchen jug and fill the reservoir without ever disconnecting it. Much easier.A note on the freezer blocksYou’re supposed to freeze the supplied cooling blocks for around 8 hours and pop them into the reservoir before adding water (otherwise you can’t gauge the correct fill level). They do seem to help – I experimented with four blocks one night, and although the water ran out after about 6 hours, the air definitely felt cooler. My one gripe is that they simply float around loose in the drawer; a simple clip-in cage would have been a much better design.The bottom lineDoes it work? Yes – on a couple of nights we actually had to switch it off halfway through because the bedroom got too cold, then back on again a few hours later when it warmed up. So it can genuinely make a difference.My advice to potential buyers:• Don’t expect air-con levels of cooling, especially in humid UK conditions.• Follow the positioning instructions carefully – that open window for airflow is non-negotiable if you don’t want a very humid bedroom.• Use a jug to fill the reservoir and save yourself the hassle.• On the plus side, it’s very quiet, which for sleep is a huge win. ### ⭐⭐⭐⭐⭐ Miniature hurricane *by on Reviewed in the United Kingdom 26 June 2026* This thing is unbelievably good! Just short of a mini hurricane. It makes my old 46in tower fan feel like a paper fan. When this thing is switched on, you really feel it. Even on its lowest setting it does the job. Quiet enough to keep on all night, not loud at all. It’s a bit weighty but that’s down to it being filled with water to help the cooling. Really easy to use, fans aren’t all that complicated! The remote works really well, I usually have an issue with them being glitchy if you don’t hold them or aim them perfectly, but this one is fine. The evaporation is noticeable. You can’t see a mist or anything but it definitely feels cooler side by side with a fan that doesn’t have a water tank built in. Love that it came with two freezer blocks which means you can rotate them out the freezer so there’s always a cold one in the fan! Very solid fan! Worth every penny. ### ⭐⭐⭐⭐ Pretty good fan & pretty quiet. The water reservoir is a bit tricky to clean but still a good buy *by on Reviewed in the United Kingdom 6 July 2026* It’s not a aircon system and does cool the air like an air conditioner but it does blow cool air at you and is quiet enough for sleeping at lower fan modes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/820652162-dreo-40-evaporative-air-cooler-35db-silent-cooling-fan-that](https://www.desertcart.us/products/820652162-dreo-40-evaporative-air-cooler-35db-silent-cooling-fan-that) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-11*
