What experts liked

The first feature worth mentioning is the 5-stage filtering system. Aside from the carbon filter, there’s also ion exchange technology included. This makes it one of the best solutions for removing fluoride, as well as other contaminants such as heavy metals and organic and inorganic compounds.

ZeroWater filters use 5 stages of filtration, to bring you cleaner, better tasting water, unlike many water filters and pitchers. Instead of carbon filtering only, our filters use Ion Exchange Technology to reduce contaminants into the water.

The dispenser, which is designed to fit on a refrigerator shelf, comes with a TDS meter so that consumers can test their water at any time. The filtration system comes with a guide that tells how much TDS is in most municipal water supplies, and consumers can verify the actual amount for themselves with the included test meter.

An Overview On Water Purifiers

For many homes, a water purifier helps keep drinking water safe and can improve the taste of the water. They can come in a couple of different forms: gadgets that attach directly to a faucet or the more popular jug purifiers that incorporate a filter directly into a pitcher or other receptacle. In the latter versions, you simply pour water into the pitcher, and it trickles through a filter into a lower reservoir, cleaner and tastier.

How does it do this? In almost every case, personal water purifiers use activated carbon to filter impurities. Carbon is very effective at catching a wide array of particles through the process of adsorption, catching chlorine and other unwanted substances in its pores. You can expect carbon filters to remove particles measuring anywhere from 50 micrometers down to .5 micrometers (a micrometer, also known as a micron, being a mere one-millionth of a meter). You might find that measurement in the specs of a purifier or even in the product blurbs if it’s an especially low number.

While carbon filters are great at removing most toxic particles and organic compounds, they’re not so good at catching minerals. Mind you, many of the minerals you’ll find in water are beneficial ones that the body needs, like calcium and magnesium. Even so, some purifiers opt for a secondary filter that can catch bad minerals and leave harmless ones in the mix.

So how do you know what kind of purifier you need? Since even the most thorough jug filtration systems won’t break the bank, it can be easy to just choose the most powerful one. But purifiers with extra layers of filtering can take time to push that water through the system or need more frequent replacements — a big hassle for large families on busy mornings.

It might be best to find out what contaminants are in your water to begin with, and you can do that by getting a water testing kit. They can be obtained from most state or local health departments. The website of the Environmental Protection Agency has a handy list on its website if you’re not sure who to contact first. Those kits will tell you the kind of substances that might be making your water taste funny (like zinc and chlorine), and raise a red flag for harmful and potentially fatal chemicals like lead.

The Water Purifier Buying Guide

  • Jug purifiers are super convenient and simple to maintain, and you can even take them on a picnic. It can be easy to forget that they’re even filtering your water, unless that process takes awhile. And with more powerful, multi-stage filters, it typically will. The process of purifying a full jug of water can vary widely between brands and models — anywhere from a minute or so to ten minutes or more. That can be a pain for impatient kids on the way out the door to school, but the trade-off might be worth it if you’re extra health-conscious.
  • One sacrifice for the convenience of a jug purifier is the relatively frequent replacement of the filter. As activated carbon accumulates particles, it reaches a point where it can’t adsorb any more from the water. A filter change will get your filter cleaning again, and how often that should be done can vary. About two or three months is standard for most systems. It’s a good idea to price the filters before you buy, since frequent, pricey replacements can more than offset the savings from a cheap purifier.
  • Space is a big practical concern for purifiers. Most of them are designed to fit snugly on a refrigerator shelf, though some compact models can be small enough to slide into the fridge door. That’s great when there’s not a lot of room, but of course, you can expect to fill it up more frequently.
