3-Pack ZeroWater 5-Stage Replacement Water Pitcher Filters Expired

Zero Water uses DI resin (along with a bit of carbon) to remove solids from water.

This will make your TDS (total dissolved solids, which is measured using electrical conductivity) go down -- ionized particles are (by definition) conductive.

This is different from the purification methods commonly used which are distillation (boiling and condensing), reverse-osmosis (membrane filtration), and carbon filtering (adsorption).

It works by using postitively and negatively charged plastic beads (resin) to attract and cling to oppositely charged particles in the water. Imagine water with tiny iron shavings in it, and pouring that water through a bed of magnets. The water coming out will be free of (most) iron shavings.

However, since it only works with conductive particles, it only filters out certain things. For instance oils, soaps, and organisms (bacteria, viruses) will not be affected by this and will mostly get through the filter unless trapped by the small amount of activated carbon or caught in the filter mesh.

Some things to consider:

1. Removing all dissolved minerals is not natural. Water has minerals in it which are necessary to survive and be healthy, and drinking completely de-ionized water will actively remove minerals from your body as it is processed. That said, unless you are not eating it is highly unlikely this will harm you

2. Removing all dissolved minerals makes water taste funny to some people. Highly purified water is often 'remineralized' after processing so that it doesn't taste synthetic

3. Removing the anti-microbials from treated water can allow it to go rancid

4. TDS meters are often included with Zero water pitchers and people encouraged to use them to test the quality before and after filtration. TDS meters rely on electrical conductivity to detect particles and as using them as the definitive measure of drinking water quality is incredibly deceptive

5. DI filters are mostly used after pre-filtering, since using them to remove everything from the water is wasteful since filtration materials like actived carbon are orders of magnitude cheaper

6. Reverse osmosis filtration systems are much more cost effective in the long run, especially if you have hard water. Hard water will deplete the zero water filters very quickly and they are expensive.

Crazy deal 🔥🔥🔥🔥, I usually get them for about 10 bucks a filter
