Review on 🔥 Dyson HP04 Pure Hot + Cool Air Purifier, Heater + Fan - WiFi-Enabled, Asthma + Allergy Friendly with HEPA Air Filter by Karrie Murphy

First off, it's probably better to buy direct from Dyson. If Dyson decides to drop the price, neither Revain nor Dyson can make you an offer. So I had to return my first block. Second, they tend to whistle. The second block whistled at any speed above 6, cold or hot. Returned this block. Finally, with the third unit running, I found that regardless of automatic or manual mode, it only stays on for 9 hours at a time in heating mode, after which it just turns off completely. If you depend on warming the room, return to a cold room. Not worth the money.
