You are basically making expensive de-ionized water using these, Normally ion-exchange happens at the end of a filter process, to remove the last of the dissolved solids while using much cheaper and more durable filters in the initial phases. For example particulate/sediment -> Carbon -> Reverse Osmosis -> Ion-exchange. By skipping the previous steps you making the ion-exchange beads pull everything by itself. These things are not cheap and they don't last very long especially if you have a lot of minerals in your water. They are typically re-used by industrial users because they can be recharged quite cheaply compared to their purchase cost, but that is not an option with zero-water unless you want to take apart the filter and separate the beads (anion and cation beads) then wash one with hydrochloric acid and the other with lye. I have done this and it is cost effective, but it is not easy.

Also, ion-exchange only removes charged particles from water. Things like salts and metals, but will not remove things like pharmaceuticals or soaps or oils, and will not affect microbes. So, you should know that.

What would you suggest then for someone living in an area with very hard water? Mostly looking to reduce the calcium but want the filter to last a decently long time. Zero water says for my water hardness it'll only last about 9 gallons or so

You can get a full RO system with filters a bit more than just this set of filters. Look up "RO system under sink tank" on amazon to get an idea of what options you have, then you can go to a dedicated place like aquaticlife to order a system. Whatever you do, get a brand which has their own filters and has offices in the US so that you can actually talk to people who know what they are doing and can recommend you things based on your individual water issues.

ZeroWater is making TDS(total dissolved solids) to 0, salts is something that dissolvable in water

I have one and our house loves the cold water. If you have really
hard water the filters can go fast (and taste like citrus when they fail) but I love mine and think the cost is worth it for my water

Yes? Did you misunderstand something, because I said that it removes salts.

These are great for the office, where you can't exactly install a RO system. They're expensive but you don't have to change out the filter right when the TDS goes up to 1 or something. It's fine to have some TDS in the water.

I only recently purchased a ZeroWater pitcher for watering my picky plants (didn't want to keep buying distilled), but I'm wondering, since people have mentioned that the water starts to taste sour when the filter is done, does it start adding something to the water, or... what, exactly is happening to the water that it starts to taste sour? I originally thought that the filters would just slowly lose efficacy as they filled up with particulate matter, and would produce water that was closer in quality to tap, but the souring water thing is weird to me and makes me think I'd then be poisoning my plants with something extra and unwanted.

If your target has some of the single packs of these they may be on clearance. I got 4 of them for 4.79 a piece (70% off)

I love the answer of 'install an RO system' like everyone can just do that. Such a waste of a post.

So, what is your conclusion, ZeroWater or others? Do not forget a conclusion after write long!

I did this exact thing, went with APEC and never looked back. Now I'm getting 005 reading water on tap with the TDS meter without waiting for the drip style pitcher like Zero water filters.
