Suggestions for an over-engineered water filter? (lemmy.world)

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?

If you go the RO option (not necessarily the best), be aware that if the tap water is chlorinated you need an active carbon filter before the RO membrane as the chlorine will otherwise damage it. And that active carbon filter will likely need replacement quite often.

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).

Oh that's definitely something to make note of, thank you!
