Local tap is dubious at best and leaded at worst so we fill 5gallon jugs at a filter station the next town over. I’m getting tired of transporting and paying for water, so I’d like to make a filter that won’t just clog up with hard water in a week. Anyone have recommendations on where to start?
Anecdotally, I put in a small under-sink carbon block filter for the kitchen which claimed it was good for 20,000 gallons. I thought that would be a really optimistic claim and I’d have to replace the filter every few months, but its been over a year and it still has the same amount of flow as it did when it was new, and seems to be removing the chlorine still (I can’t taste it, anyway).
