bedroom vaporizer for elderly mother
What is the best and safest vaporizer to put in my 87 year old mother's bedroom. Her rom is small, about 12x14. She has macular degeneration so cannot see well at all. She has been getting a lot of nose bleeds lately and I think iot may be because the furnace makes the air in the house so dry. Is steam better than cool mist? Is it worth the money to invest in an ultrasonic vaporizer for this purpose?
Thanks so much for your help.
