The 420SP is the size of two VHS video cassettes stacked on top of each other. It is the lightest CPAP on the market. Best of all, it is built to last and backed by a two year manufacturer warranty which means that although it is a travel CPAP, you can plan on this little guy lasting as long as any other CPAP on the market. It is a great machine.
This model is no longer available. A suitable replacement for this single-pressure travel machine is the Z2 Standard Travel CPAP Machine. The Z2 is small, compact and lightweight— fits in the palm of your hand. It's also 29% quieter than the previous version, making it an ideal travel companion.

This small CPAP has been very popular because of the size and weight, especially as a second machine for travelers, but it can certainly be your 'every night' machine with as long a life expectancy as any other CPAP. It is a great product.

CPAP.com Battery Kit for GoodKnight 420 Series MachinesAny mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:
When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

Works as needed! Perfect fit for night stand! Still working after 8 years! I wish it was still available!! Very happy!!
great machine- very quiet
This little machine is great! It's very quiet, the ramp feature is really nice and it really is compact. I was also very happy with the bag that comes with it. It's sturdy and pretty well padded. I recommend this machine.
I'm very happy with the new cpap machine,much smaller than my last cpap and works better also.
GoodKnight 420SP CPAP is a reliable device
The first two nights were difficult getting accustomed to this mask, oxygen in my face and trying to breathe normally. I sleep on my stomach and am learning to sleep on my back. I think it will get better sleeping through the night. My wife, says she is doing well and is now sleeping through the night. The CPAP & humidifier are great. I recommend the humidifier when purchasing the CPAP.
I purchased the GoodNight 420SP as a travel back up for the CPAP machine I regularly use, a GoodNight 420S. The online description did not make clear the difference between the GoodNight 420S and the 420SP. In fact when you clicked on the word 420S you were directed to purchase the 420SP. The 420S senses pressure in the mask, the 420SP senses pressure at the machine outlet. The 420SP has a dummy peg for attaching the sensor tube of breathing tubes that have the sensor tube. Thus the photographs look identical. I now have used both and do not notice any subjective difference.
I am well pleased with all that I purchased. Fast service and great help Thanks again
The GoodKnight 420SP is working like a champ. The bigest advantage I see in this CPAP over the others is the size and sound. It uses only a small amount of space on the bedside table compared to other units. It additionally is so quiet, you barely know it is in the room with you. It is very portable and also has a two year guarantee just like the bigger machines. I ordered mine with the humidifier which is also working like a champ.
I read a LOT of reviews on this product and many others and almost didn't buy this one because of the reviews I read complaining of the noise from this machine. I asked customer service about this issue and was assured of its relative quiet. They were right. I can compare this with my Respironics that I have used for years and this is quieter. My guess is the reviewers that didn't like the noise maybe hadn't had CPAP before. This is an extremely quiet unit. I kept my Respironics on the floor under the bed because of size and noise. This unit sits right on my bedside tabletop. I couldn't be happier. I am also pleased with CPAP.com shipping both user and tech manuals. One sure doesn't get that with local DME suppliers.
Great Machine. Light weight, even with the humidifier. Combined with the Silverlining software, tracking compliance and performance is a wonderful utility.
Quiet but powerful. An excellent product.
