Filtering Your Water

A human can go for weeks without food, but without water we can only make it about a week, at best. Our bodies consist of about 70% water. Water that is free from a wide range of contaminants should be a high priority.

June marks the beginning of the warmest months of the year, and a time when we all (should!) drink more water. But even in places with “good water,” what comes out of our faucets is often contaminated with a wide range of toxins, heavy metals, and trace pharmaceuticals. This month, I invite you to invest in a filtration system that will improve your water, health, and peace of mind!

The sheer volume of water-treatment options is staggering. We offer only a limited number of filtration systems in our online store because most folks need only one of a few options. We see no need to make things more confusing!

You can learn more in our article, Do You Need a Water Filter?, but below I’ll tell you what you want to get out of your water, and then four filter options that will do that.

Filtering Your Water

The main things we want to get out of our water are as follows:

1) Chlorine

Chlorine is used to kill many biological agents, including bacterias like cryptosporidium, giardia, and cyclospora. Chlorine is incredibly effective, but chlorine in drinking water is implicated a wide variety of health problems, from cancer and heart disease to reproductive problems and more.

2) Heavy Metals

Lead, cadmium, arsenic, chromium, mercury, and more easily bio-accumulate in our bodies and can cause serious long-term health problems.

3) Pharmaceuticals

This is a relatively new source of toxins now found in water supplies throughout the world. Pharmaceuticals pass though those who take them and are eliminated through our urine. They are flushed and later show back up in drinking water.

4) Industrial products/byproducts

DDT, Dioxins, Percholate, Hexachlorobenzene, MtBE, PCB’s, Chromium VI and many others can now be found in the water of many towns.

5) Radioactive elements

These are now showing up in some locations. If you have them, you should of course filter them out. This usually requires reverse osmosis technology.

6) Fluoride

There is robust debate over the use of fluoride in drinking water. Some believe it to be okay while others can point to studies suggest it is a potent neurotoxin. I choose to filter it from my water.

Filtering Your Water: Choosing the Right Filter

We offer two basic types of filtration systems in our store.

  1. KDF/GAC/carbon block filtration. These filters take care of most of the contaminants found in municipal drinking water, including PFAS chemicals. This model includes an optional fluoride filter. Requirements: A hole in your countertop. Do you live in a city? If so, you should invest in a pre-filter for your system.
  2. ZIP Countertop Reverse Osmosis filter systemThese filters are perfect for folks who cannot put a hole in their countertop and/or have the modern type faucet that will not connect to the KDF/GAC/carbon block countertop unit. They are also great for folks who may have radioactive elements in their water.

A Word About Reverse Osmosis (RO) Filtration

RO does a great job filtering water of just about everything. One of the downsides is that RO traditionally wastes 4-5 times as much water as they produce. The ZIP limits the amount of waste-water and even stores it in a special chamber so that it can be used elsewhere in the home (we use ours to water plants). RO filtration also removes beneficial dissolved minerals, so care should be taken to be sure that your diet contains these trace minerals. For most of us that is not a problem.

What About Charcoal Filtering Bottles?

Activated carbon is a great filter medium, but usually water is forced through the charcoal by the pressure in the system. When you just drop a stick of charcoal into your water bottle and head off to yoga, there is simply not enough time for any significant filtration to occur.

Finally, water also enters into our bodies when we shower and the chlorine that’s added to all municiple water sources enters with it. Chlorine can also become a gas when heated and thus get into our lungs when taking a steamy shower. To prevent this, it’s worth considering a shower and/or bath filter.

I hope this helps. Feel free to ask questions.

Stay Sane,

    Hi John,
    I live in Canada where we need humidifiers running daily from November until the end of April. Because our water is very hard in Toronto Canada, this also poses a problem using the tap water in our cool air evaporative wick units so we have had to use distilled water to deal with this issue, otherwise we are putting the water right into our air as well as having to change or filers weekly to combat this issue.
    My question is, how do we use 1 type of water for drinking and the humidifiers? is this even possible?
    we go through at least 3-4 Gallons per day of distilled water for our 2 humidifiers and so having it delivered in large delivery size to go into a unit seems most logical as we would never be able to make enough of this in a countertop unit daily ourselves.So my question is, if we invest in a delivery service of RO water in a large glass container instead of plastic, can this be used in our humidifiers as well? or do we need to have 2 units 1 for distilled and another for RO. we do not have a separate hole in our countertop where we rent.

  2. Drinking water is our vital need because it serves dozens of essential functions that keep us going. And of course we must take care that it is safe for our body.

    Each day people have to consume a certain amount of water to be healthy. The amount can vary depending on your gender and age. Nevertheless, generally, an adult man needs about 3 liters of water per day while an adult woman has to drink about 2 liters of water per day.

    Because of the rush of city life, we forget about this essential need. So, there are some good apps capable of monitoring your water intake and reminding you about that:

    Similar questions – whole home filters seem to cause limitations for large homes and families with flow rates that aren’t terribly high. I have four kids who will each have a bathroom sink, as well as a master bath sink. What would you suggest for a bathroom sink where a full filtering system isn’t practical? Ie, teeth brushing and water consumption on occasion? This issue for a large home is driving me batty!! So many options and none seem very good.

    Have you done any research into the pure effect ultra water system? They seem to be a really good, although expensive, filter. Also, what brand is the countertop triple filtration system that you sell on your website? Thanks for all your research!

  5. alison

    hi, what about this one (I wish I could buy the one you reviewed but can’t afford)

    1. Lien

      I’m curious about this too! I am trying to decide between Aqua Tru and CuZn UC-200. https://www.amazon.com/dp/B000923524?ref=myi_title_dp

  6. Christa

    What about whole house filters? We are now living outside the city and want a system that will filter the water before entering our sinks, showers etc. We’ve been looking at the Radiant Life products. Thoughts?

  7. Andrea

    Thank you for the information. Was very interested in the crystal quest bath ball for my kids, and was about to purchase it, until I read the reviews on Amazon.
    Do you have personal experience with this? Or possibly there are other comparable products?
    I know this is important, but I want something that is reliable, and it seems that though this is a great concept, some issues still need to be worked out.

    1. John

      Hi Andrea,
      Thanks for the question.

      You are correct; tub filters are notoriously difficult to design because a bathtub faucet is unlike any other typical faucet in our homes. The end where the water comes out has no good way to attach any sort of filter. A shower head filter does not have this problem.

      The bath ball we offer is the simplest way around the problem, but we have found no bath filter that does a better job.
      Because bath/shower water is hot, there are a number of difficulties involved in making them filter as well as a kitchen filter that uses cold water only. Because of this, bath/shower filters are mostly meant for filtering chlorine, which can be filtered from hot water.

    For the reverse osmosis filters, what is the best way to make sure we get the trace minerals?

    1. John

      Thanks Danell,

      You are correct, getting beneficial dissolved minerals back into water after it has gone through an RO filter can be problematic.

      One of the many great features of the ZIP filter we offer is that it has a “post filter”. This is the last level of filtration…after the RO. The post-filter reintroduces minerals back into the finished water. EASY! You don’t have to do anything extra. When it’s time to replace the filter cartridges, the new one starts the process all over.

    What about aquasana brand? I have their shower filter for now and wanted to get their 3-stage…..?

    1. John

      Hi Sumiyah,
      Aquasana makes a wide variety of filters so it’s hard for me to say. One thing to look for is filter cartridge longevity. Many filter manufacturers recommend buying a new set of filter cartridges every six months.
      The system we have suggests changing filters every 2-3 years. This is because they are so well built and the technology is great. This means lower costs over time and far less hassle.



  10. Vaidehi Deo

    Thank you for the post.
    Wanted to ask about https://www.drinksoma.com/ Drink soma pitchers. Are those any good ?

    1. John

      Hi Vaidehi,
      Generally speaking, countertop/gravity type filters do not do the same kind of job that more robust filter systems do. They are better than nothing but…

      This will include the Soma.

    Hi there. Are you concerned about the storage tank being plastic? A stainless steel tank is available for the under the counter ROs, and I am wondering if it’s a good investment.

    1. Maia James

      Hi Liz,
      John here…
      An under-counter RO system with stainless tank can be good but there can be problems depending on which system you are considering. We are about to offer just such a system. You can contact me directly for info. john@gimmethegoodstuff.org
