Hi!!! It doesn’t matter what brand just as long as it’s sterile and it’s 7% Saline I get mine at Walmart with a prescription from the doctor and they gave me a coupon to get it cheaper they’re always so nice about that. I thought that it would be on my a plan to pay —-Humana it’s not. so bad when they give me the coupon to get some money off on it I also thought that Medicare part B would pay for it since it goes into a nebulizer but they told me no on that too I think it’s just Humana thank you
