DeLonghi NF190

very good – I've had this unit for about 2 years. It has worked very well in a 6mx6m room. Easy to set up. The only problem is weight, if you want to move it up and down stairs it will be a problem for older people and most women to do by themselves. It's quiet enough to sleep with and it works! bit heavy if you want to move it around a lot, but it does have wheels.
