We plan on having two filters going before our water tank when we fill our tank, one's a kdf/carbon filter and the other is a five micron sediment filter. We want a separate drinking water faucet and I'm wondering if it's even necessary with those filters going into the tank? Would a single one micron filter be good to have inline before the water faucet or is that doing too much? If it is, then I'd just avoid having the drinking water faucet. What's your thoughts on this? Not sure if that's enough filtering for drinking water or not. TIA :) #lifestyle
