  1. Resmed S9 Autoset 3 Star Review

    Posted by on Mar 25th 2021

    Ordered CPAP machine on 3/16/21. It shipped on 3/18/21 and I received it on 3/21/21. Used it for 2 nights and noticed that the machine made a noise after every exhalation. Called CPAP Liquidators to return it for a replacement on 3/23/21. Hope to receive replacement by 3/28/21?

  2. Refurbished ResMed S9 Autoset 5 Star Review

    Works great. As described. Bought it to replace one I already had (and love) that was starting to make whining sound later at night. Did not come with SD card, so used the one out of my old machine. Good working with these people.

  4. Hassle Free Purchase 5 Star Review

    Posted by on Jun 16th 2020

    I've been wanting to have a backup unit "just in case" for a few years now. The one I bought from CPapLiquidators has now become my primary machine, with the other unit, which has many more hours, reverting to backup status.

    The machine I purchased here was like new. The technicians had the pressure set to my specifications and the unit was shipped promptly.

    The ResMed S9 Autoset is a highly recommended CPAP machine and has served me well.

    Condition, delivery, and operation of this product was exceptional. Everything was as it should have been if I had received the unit new. However, I neglected to get an SD card to go with this unit. Unit works GREAT just as advertised. Thanks.

  7. great service 5 Star Review

    loved the S9 Autoset and was very disapointed when it went out of production as it suits me perfectly, both for home and travel. A refurbished one answered all my issues and it is poerfect, thank you

  8. Is this thing even on?!?! 5 Star Review

    Posted by on Mar 22nd 2018

    I just recently switched to this ResMed S9 AutoSet after having a traditional CPAP machine (ahem...the SAME machine) for 10 years. Last night was my first night of therapy with it and if it hadn't been for the pressure coming through my mask I never would have known the unit was on! This is simply the quietest CPAP I have ever heard (or rather...not heard!) and I loved the range feature of auto-titration. So happy that it is also significantly smaller than my previous machine so traveling will be much easier now!

    The Refurbished ResMed S9 Autoset CPAP I received looks brand new. I wanted a backup unit because my current unit is going on seven year now with no problems. This product works wonders it's so quiet you won't even notice if it's on. The automatic pressure adjustment works well and not give more pressure than is needed. Looks great and it's built with high quality standards, I’m very satisfied !!!

  10. Fabulous Product(s), Fast and Friendly Service 5 Star Review

    Posted by on Dec 28th 2017

    If you are in the market for a CPAP or any other breathing assistance device, look no further. The selection of products is only matched by their fast and friendly service. It all makes you kind of glad you have to use such a device. And support (from initial setup to whatever you need) is only a toll-free phone call away. Save your breath and find everything you need (and want) from my friends at CPAP Liquidators.
