    Water Chamber

    Exactly like the one came with my Resmed-10. Its nice having a replacement part. it allows me to wash and dry my other chamber without worrying about having it ready to use right away. Also a piece of mind knowing i have a spare

    Perfect fit

    Fits perfectly in my machine and works just as well, for a lot less money, than what I was buying from my local store. Shipping was fast, and I will definitely be buying again.
