What kind of filtration system does the Spout have?

We have a MERV 7 carbon felt air filter to remove VOCs and odors, plus a MERV 13 air filter to remove particles as small as 0.3 microns. These filters can capture smaller mold, smoke, and allergen pollutants in addition to bacteria and virus particles. There's also a UV-C sterilizer inside to zap the fresh water, followed by our NASA derived water filter pack and remineralization cartridge. Cheers!
