SW Iowa | If you're at all handy to do the installation yourself, $2-300 will buy you a compact drinking water reverse osmosis system with a separate small pressure tank / reservoir. I bought an iSpring RCC7 off Amazon because it seemed like their filters mostly used generic sized housings but Menards sells systems if you want to look at/buy something locally. Consumables for mine run maybe $20-40/yr, I think? I also added a UV filter ahead of the RO in my system because were on an old hand dug shallow well that doesn't have a fully sealed top... so although it never made anyone sick in 40 years bacteria is also present and to my understanding can set up shop on the RO membrane (if you're on a new well / drilled deeper that may not be a factor for you).
These type of systems are designed to put in the cabinet under the kitchen sink, but in our case I actually installed the system in the basement and ran the supply line up through the floor... that way filter changes or any other issue doesn't lead to a bunch of water in the bottom of the cabinet. I don't recall the number but you do need fairly high water pressure for the RO membrane to work (I had to crank up the screw on pressure switch for my pump).
If you opt for non-RO filter, do your research. Most of the filter pitchers and faucet-attached filters are mainly to help taste, and some of the non-RO under cabinet filters are the same way. My understanding is charcoal doesn't do anything for nitrates. | |
