I go through a TON of those between the 2 houses. Strictly a sediment filter. I typically buy the 5 micron filtering size, as opposed to the 30 micron. The least expensive place I've found centrally here is a farm and ranch store called Atwoods, at $1.99 per filter. They will usually have them in stock, if I haven't cleaned out their inventory! I change mine monthly, using 7 cartridges between the 2 houses. The farm house has a ton of black sediment that's coming up with the new pump, so I built a 4+1 filter manifold prior to the Kinetico water softener. The first 4 filters are in parallel, dumping into the last and then to the water softener. It's been amazing to watch the stuff coming out of the house pipes, once the stuff going in got minimized! Even my MIL's hair stylist has been able to tell a difference.


Unless you go through a TON of water or get into a very heavily sedimented water supply, I would expect you could easily get 2-3 months out of a couple filters. They will look much dirtier in the canister than they will once pulled out and dried.
