Free Respironics heated hose

Someone donated a bunch of masks and hoses.
The masks I have found some homes for but I am having problems finding someone who wants the Respironics heated hoses.
I need to check the product numbers and see which models they will work with ...
If anyone wants one or two or three or all of them....send me a PM and I will check the product numbers.
The bulk of the hoses are brand new still sealed in the package.

If no one is interested I will just take them over to a thrift store that I know of in another town that will accept medical equipment.
I want them gone out of the donations box. Taking up precious space.
