Multi-function filter cassettes

Trachi-Naze multi-function filter diagram

The Trachi-Naze multi-function filter cassettes are the heart of the Trachi- Naze System

They contain three filter layers which when sealed onto the skin through the baseplate create a "closed" system, ensuring that all air is warmed, humidified and filtered, and restoring a functional airway resistance.


Blue filter

Night Filter (Blue)
Provides normal airway resistance adding back almost all lost resistance.
The blue (night) filter provides the normal airway resistance which improves oxygenation — these filters would be normally worn at night and can be easily tolerated during sleep.
Green filter

Day Filter (Green)
Half airway resistance allowing free passage of air for daytime use.
The green (day) filter is comfortable during the day for normal activity - it provides half the level of airway resistance — but it is the regular use of the Blue and Green filter which maximises respiratory performance.
Orange filter

Active Filter (Orange)
Minimal airway resistance allowing strenuous activities.
The active (orange) filter enable wearers to carry out strenuous activity without losing the protection offered by the filters. It has minimal airway resistance.

Normal use indications: 2-3 filters every 24 hours. Initially upon introduction to the system for the first few days the number of filters may be higher (4-5 filters every 24 hours) - this will settle down after the initial period - approximately 3 to 5 days.
