Some units give you different fixed timespans for each. For that reason, I just use the Reverse Osmosis stage and ignore the rest. RO is the last step, and in theory it renders pure water meaning the only reason to have the previous ones is to pre-filter somewhat the water and extend the RO cartridge lifespan. Problem with that is, first, there's no way to gauge when each filter is spent. Second, they're priced the same anyway, so why even bother. Just go straight from tap to RO! Keep the post re-mineralization stage if you want.
- tguvot 1y agopre-filters typically have specified "capacity" in gallons. which is measurable. also if water is very dirty filters get clogged and pressure dropped. it's also measurable. "post re-mineralization stage" is actually "ph adjustment".
- Xss3 1y agoIt isnt merely ph adjustment... You want some amount of minerals in water for your health, plants, and taste. Changing the PH isnt the concern in most cases, its just part of the result.
- mousethatroared 1y agoFood gives you all the minerals you need. Matter of fact food can cover most of your hydration needs.
- bernawil 1y agoTrue. But have tasted distilled water? Tastes metalic. Probably just my imagination but I feel like it pulls stuff from the mucous in your mouth and tastes like blood.
- BugsJustFindMe 1y agoIt is your imagination. I drink distilled water all the time and it tastes great, not metallic at all.
- bernawil 1y agoyou sure it's distilled? if you measure dissolved solids with a water quality tester does it read 0?
- tguvot 1y agoAll those filters are specifically made for PH adjustment (you are welcome to look at specs). There are bunch of different formulations depends on how much PH adjustment is needed. RO makes water more acidic. if water was somewhat acidic to start with, it can get more acidic or become corrosive.
- bernawil 1y agoAre you sure that it makes it more acidic? AFAIK it only outputs pure H20, should be neutral. If you feed it alkaline water you'll get "more acidic" water, but the other way if you feed it acidic water.
- Xss3 1y agoThe spec doesn't tell you intent it tells you the resulting product performance. Ph change is one part of the result, not the goal. The goal is water purification.
- tguvot 1y agoi am talking here about post-filters for PH adjustment. their goal is PH adjustments those for example https://www.freshwatersystems.com/collections/specialty-cartridges?q=&filters=%5B%5B%22named_tags.Contaminants%20Reduced%22%2C%22PH%20Neutralization%22%5D%5D https://www.freshwatersystems.com/collections/specialty-cart... or those https://www.freshwatersystems.com/collections/filters-media?q=&filters=%5B%5B%22named_tags.Cartridge%20Style%22%2C%22Inline%22%5D%2C%5B%22named_tags.Contaminants%20Reduced%22%2C%22PH%20Correction%22%5D%5D https://www.freshwatersystems.com/collections/filters-media?...
- bernawil 1y agoI know pressure drops. The problem is knowing which filter is the one causing it in particular. Also, filters that are spent at different rates are a PITA. What I mean is if you are going to feed it nominally clean tap water, there's no reason to protect a catridge with equally or more expensive cartridges. Just use the RO filter and be done with it.
- tguvot 1y agoyou can put pressure guages in between or one of $10 flow meters before system. RO membrane doesn't remove chlorine iirc or vocs. On the other side chlorine degrades membrane. "nominally clean tap water" can have enough dirt to clog membrane if you don't auto backflush it frequently
