Hmm, ok i'll bite-
Movement of air will cause heat loss in things which has moisture (like air. Even our new build which is insainly dry has 15-20% humidity, older homes will have 30%+). I can go further "why" with science but lets keep it laymans.
It will also create a flow of air and pressure (positive or negative) to push out hot air and pull in cold from the surroundings. The motor creates a positive net outcome of cooling the room. eg, fans in a PC case, extractor fans, ceiling fans, car fan (interior) etc..
Evaporative cooler is the same, it has a fan, and it does pump air around- the main difference is that it has a built in heat exchange* already rather than use the surrounding moisture to take away heat. Though you can say its more efficient, the counter argument would be weight, size and power vs requirement. You need a hefty amount of air to make it efficient in a evap cooler. Hence why you don't see "hand held" evap coolers, instead you see portable fans...

Now explain to me why a fan doesn't cool the room? :neutral_face:

Thank you for letting me know that, much appreciated.

It is only 45watts maximum which for 6 hours is less than a third of a kWh. 1kWh is usually between about 10p-15p therefore 6 hours would be 3p-5p.

Just gone ahead and ordered two while they are in stock, thank you.

3p to 5p seems really cheap - would that be on setting 3 and on for around 6 hours then? I was about worried what the cost would be if my son was running it for that length of time (or even more, if overnight). Thank you.

Whilst you may feel cooler with a fan blowing on you it does not actually cool the room ( it actually heats it up from the heat generated by the motor ) . An evaporative cooler ( humidifier) does actually cool the air in the room.
Can someone who frequently uses one of these provide their honest feedback about how good/ bad this device is?

As a direct comparison, this tower fan blows less air (about 65%) on full power than a conventional 12" fan on minimum.

Does anybody know how much one of these would cost to run? My son has a very small room that gets really hot in the Summer. If he had it on for around 6 hours at full speed, how much would that roughly cost me? Thank you.

Tesco seems to make out the cost is around £2 a year, although they don't mention how they got to this.
6 hours a day would probably cost something like £5ish a week maybe?
A humidifier might be a better purchase.

Depending on your tariff 3p to 5p a day.

£5 a week?? Hmmm! Depending on your tariff 3p to 5p a day. What has a humidifier got to do with a fan?

Some worrying reviews , not very powerful and poor design , so has problems when oscillating.
Probably better off with the cheaper Wilko model or a traditional circular fan.

To counter those neg reviews (a very small amount of of hundreds), but it does appear the two reviewers either did not put the base on, or failed to realise you put the power cord through the centre of the base and there is a notch for the cable to run through.
Absolutely no oscillation issues here if you read the instructions and assemble properly

Checked this yesterday at 3pm, not in stock, so a 30 min drive to a store with Stock (use checker on website), get home and today find it came back in stock yesterday evening.
Assembled, pushes out some good air, Fan not the quietest, but it is a fan moving air so can't be silent, but all working and quite impressed for £20

The quoted dimensions & weight are a bit dubious.

Hmmm, this fan for £20 or the Dyson Cool™ Tower AM07 for nearly 18 times more and does exactly the same thing.
Tough decision.
Heated op.

I found that corrupted by HUKD too.
Maybe it will work better if it is made to look as if it is not a URL xttps://www.tesco.com/direct/tesco-tower-fan-3-speed-white/300-7891.prd
Just copy and paste then replace x with h.
