AWESOME!  All I can say is PEACE OF MIND!  Very easy to set up.  Great instructions online, if needed.  Good looking piece of equipment.   I have ours set up in our bedroom since we are in there sleeping for hours.  Great to know that it’s getting rid of particles we cannot see like allergens, pollens and dust.  We have 3 dogs so it’s even better since they shed all the time and roll around in the grass!  It is a quiet machine and has a long cord.  The display is so easy to read and understand.  I feel so much better knowing I am sleeping in clean air.  I am going to buy one for my living room.  GREAT PRODUCT!!!
