Co to jest?

Cabin air cleclefication devices are integrate or retrofitted systems that treet the air circulating inside an aircraft. The core technology in nearly every modern system is High-efficiency Particulate Air (HEPA) filtration. These filters are constructod from a dense mat of Randily arranged fibers, typically borosilicate glass or polyene, and can trap aid 99.97% of parties that are 0.3 micronin diameter.

Airlines Leading the Way in Filtration

Several carriers have made cabin air quality a centerpiece of their ir poct-pandemic safety messaging. Delta Air Lines was among the e firss to highlight that its entire mainline fleet uses HEPA filters and that it introduced a process to change filters at double the controlrer-recommended frequency. Singpapere Airlines retrofitted it aircraft wigh an additional UVC destination tion system for the air conditioning ducts andd mounted high-efficiency filters on it s ground air conditioning units.
