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.

The GoodKnight 420SP CPAP can be used with a separate passover or heated humidifier. We offer it packaged with a heated humidifier at a reduced price elsewhere on our site.

CPAP machines come with a six foot hose, a travel bag and manuals. Masks are not included and must be purchased separately. We will be happy to help you with sizing and offer suggestions on current popular masks.

The 420 line of machines can experience power problems when used with a Full Face Mask at pressures exceeding 15 CM/H2o. If you wish to use this mask configuration, please consider a different machine.
