CTT Systems is launching a modified cabin humidifier to counteract the problem of volatile organic compounds (VOCs).

The company has partnered with two Swedish air filtration specialists to produce the humidifier.

Using Munters’ current pad solution together with a newly developed active carbon filter solution from Camfil at the upstream end, the new unit will reduce VOCs by up to 80 per cent and ozone by 70-75 per cent both in the air and during fume events on the ground, CTT said.

The new pad also has a service life of 4,000 flight hours, the same as the humidifier, so it can be replaced with no special tools or routines required.

The partners have produced a conceptual design for the Boeing 777X, which is just about to complete testing, ready for market launch in September. This can also be swapped out with the current 787 cockpit humidifier, CTT noted.
