the hose fine otherwise but the inside stinks there s a really awful smell coming through it [SEP] i ve ordered these hoses before and not had the current problem so i don t know what s up but the hose i just installed is almost unusable i need oxygen with my bipap but every time i breathe in at night i get a nose full of some nasty chemical smell it s bad enough that i m worried it will make my asthma worse it s so vile i ve even seriously considered washing the hose out despite knowing that s a bad plan i won t order again if the other hoses i ordered at the same time have the same stench
