you need to add automatic return to operation after power outage

This is not a fan; maybe an air purifier. Most powerful level of fan’s effection distance is around 80-90 cm. Very fancy sound machine. Total disappointment. I wish I could give it back.

I was very disappointed to find out that the “Cool” function wasn’t nearly as powerful as other Dyson machines branded as “Cool”. It feels quite misleading to use the same branding across products with much more powerful fans, because you naturally assume you’re getting both an air purifier and an effective cooling fan in one machine. The reality couldn’t be more different. The cooling performance is more like a gentle breeze than a proper fan. During a 37°C heatwave, it simply isn’t capable of cooling you down. I’ve ended up using my traditional metal rotary fan instead, which does a much better job. Even my five-year-old budget tower fan from the high street has noticeably more airflow and cooling power than this premium Dyson product. Another major issue is that whenever I use a humidifier in the bedroom to improve my sleep, the air purifier detects the water vapour as pollution and immediately switches to its highest setting. This means you can’t rely on the indoor air quality readings, as they become distorted whenever the humidifier is running. Since the purifier produces a constant stream of clean but very dry air, it’s perfectly reasonable to want to use it alongside a humidifier. Unfortunately, the machine isn’t able to distinguish water vapour from actual pollution, making the two difficult to use together. I regard this as a major flaw in the design of the machine itself. I was also extremely disappointed with the order fulfilment. When I placed my order, the website stated “Get it next day”, but in reality it took a week and a half to arrive. The order wasn’t even dispatched the day after I placed it. Overall, I have to seriously question whether this product is worth the price. If more than 14 days hadn’t passed since I received the product, I would return it without hesitation and instead buy a traditional metal fan together with a separate air purifier. Based on my experience, that combination would provide significantly better cooling performance while still delivering the air purification I was looking for.
