....like why bother with a filter system....probably best just to go the lug-a-jug, blue plastic 3-gal or 5-gal or 6-gal water container and get it filled somewhere with town water, or use the 25-cent/gal water vend machine at the Gilford Hannaford...that supposedly is Laconia town water which also goes thru reverse osmosis inside the vend machine.....and pick up a quality beer while u is there....something like Beck's Sapphire beer, 6% alcohol, and about $12/12-12oz bottles at Hannaford's
...the lake water is super-duper as a quasi-grey water system....make that an almost drinkable water system for doing the dishes, showers, washing, and maybe even brushing one's teeth, but not for drinking or cooking consumption, which is where the lug-a-jug water is used...after 21-years of doing this routine...while it is not totally 100%
