I’ve had this machine for about 6 months and have been using it constantly.  We moved from SoCal to Cincinnati, and this fan has been great with regards to cooling and filtering the air in my bedroom.  My entire family (dog included) suffers from allergies and we have Dyson’s in every bedroom and the family room.  The capability of Dyson to filter the air is just great.  In my bedroom, I haven’t had any allergy symptoms this summer, so this machine delivers.  As for heating, it does do a great job heating evenly.  The only negative I can find is heat can not be controlled via the app (it has to be done via the remote).  This is in accordance with UL 1278 compliance, so it’s out of Dyson’s hands.  If you don’t plan on changing the temp all the time, than this is perfect.  If you like to tweak the temp than you may have to have the remote always in reach.  Overall, great machine and I love it.
