This is the only mask you need until the pandemic gets over! The heating in the mask is adjustable and goes up to 90º Celius. I mostly keep mine at MAX heat. Ever since I purchased this kit I feel much safer when I go out and recommend this product to everyone. I have it on all day along with the heating on, don’t be silly and ask if 90 degrees burns off my skin, it feels very comfortable on the face to wear. I am not sure if it feels hot in summer?
