Designed for use with the Transcend AirMist, these disposable cartridges provide waterless humidification by capturing moisture from your exhaled breath and reintroducing it as you inhale, helping to reduce dryness and discomfort during CPAP therapy.
Perfect for travel or everyday use, each cartridge is lightweight, compact, and easy to install. With standard 22mm connections, they’re compatible with virtually any CPAP mask and device setup that doesn’t use heated humidification.

Which CPAP machines is the AirMist compatible with?
The AirMist connects to any CPAP mask with standard 22mm connections and can be used with any CPAP device when a traditional heated humidifier isn’t available.
Does it work as well as a traditional heated humidifier?
While it doesn’t offer the same level of moisture as a heated humidifier, the AirMist provides a noticeable boost in comfort compared to using CPAP therapy with no humidification at all, especially in dry environments.
Can I clean and reuse the AirMist filter?
No, the filter is single-use and should not be washed or reused. Attempting to clean it may reduce its effectiveness and compromise your therapy.
How often should I replace the AirMist filter?
Each AirMist HME filter is intended for short-term use and should be replaced every five to seven nights, or sooner if it becomes damp, dirty, or difficult to breathe through.
Does the AirMist require any special adapters or accessories?
No, the AirMist is designed to easily integrate into your existing CPAP setup without additional adapters or complex adjustments.
Is the AirMist a good option for travel?
Yes! Its lightweight, compact design and waterless humidification make it an excellent solution for CPAP users who travel frequently or don’t have access to a heated humidifier.
