Catechin Filter in Air Conditioners – Explained!



You see a lot of emphasis on environmental conservation today because of the ill effects of global warming and ozone depletion, and so on.

Therefore, you see a shift in the preferences of people towards greener methods of consuming energy. Air conditioners have a reputation of being one of the biggest culprits of environmental pollution over the years.

Hence, it becomes essential for the manufacturers of these AC units to come up with environmentally friendly methods. One such attempt is the use of Catechin filters in the AC as compared to the nano silver filters.

The Japanese AC manufacturers have taken the lead in this regard with Mitsubishi AC using Catechin filters to purify the air.
