If you spend Enough time on Instagram, you can start having the idea that the biggest problem that the United States faces is water. And that the best bath water filters are the only answer. Over the past few years, a new generation of newly filtered shower has come to usurp our collective social media data source and possibly our subconscious with a scary question.
Can you really believe in water flowing from your shower?
Answer, According to Wired reportNot always encouraging. Producers of filtered shower often create bold pronunciation of what the pipeline worsens and your chemical -filled bath water may be doing for your body, in what could be the only five peaceful minutes of your day. If you can escape from chlorine or pollutant in the water, the argument will occur, it may be a cure for your most embarrassing problems: everything from ruffled hair to dandruff hair, hair loss, eczema, dry skin, black head, and black head, and black head, and and and and and The heartbreak of psoriasis.
The best bath water filters on this list are really good in removing abrasive chlorine compounds that cities added to your tap water to kill bacteria. And this is our focus. It is possible that half of the country's water system, including New York and Seattle, use chlorine to disinfect the city's water supply. But most large urban areas use a more stable substance called chloramine that is considered to cause less cancer. Chloramine is harder to filter out and not all bath filters are successful.
In fact, the difference in performance is great in some cases. So, suppose you don't like chlorine in water? And you live in a city? These are the shower we propose.

The way we checked and what we tested

The market for filtered shower is still young and mostly uncontrolled, and performance requirements are rarely backed up by independent data. We have made a lot of requirements, but very few shower filtering companies deal with their laboratory results. .Thank you, AquasanaThen WeddellAnd Rhythm For exceptions.)
Some manufacturers told us that independent laboratories and certificates were backed up, and that data was released. Many people provide survey of customer satisfaction instead. All this means some doubts are guaranteed.
And so I received a kit at home, instead. I first checked the total amount of chlorine in water without filtering, a measure including chloramine or free chlorine interacting with anything in your pipe. After that, I checked the water filtered by the shower. I have performed many tests many times to take into account the inaccurate or fluctuations in the test and at the city chlorine level. In most cases, I did this for many days.
For testing, I avoided the unnecessary home test strips, and instead escaped chemical indicators that were a bit uncomfortable and used digital and chemical tests designed for swimming pools and aquariums.
We also tested the total number of soluble solids by use TDS meterAnd the effects of the filters are separately tested for pH to evaluate the effect but also to verify the reliability of the chemical test results.
Of course, the effectiveness of filters over time, of course, depending on the level of pollution is filtered out of the water, which is why filters always need to change. When we update this tutorial, we will continue to check the most effective shower filters to see how their effectiveness changes over time and add any new shower filter we can introduce.
The shower filter may not do anything
As a result, you may not expect these shower filters to soften your water hardness or remove most substances.
In the end, a filter must be relatively small to fit the shower. However, it is required to filter the water gallon every minute, pushed out at high temperatures and high pressure. A shower filter sets a scary technical challenge, compared to the water filters that only treat a small amount of water at a time or a bulky reverse oxosis that can be plugged into your underwater pipe system.
So, what do these shower filters really do, the way we can measure? They filter chlorine and chlorine compounds, mainly through chemical reactions. Quite a lot of American cities add low concentrations of chlorine or chlorine compounds to drinking water to kill harmful bacteria. This is good and good when water is still in pipes. But chlorine is not accurate for your hair or skin, and very few people like to drink it. Some are also especially sensitive to flavor or smell, or prone to skin reaction.
The most prominent home shower filters depend on the mixture of zinc-gong called KDF-55, which is known to be quite effective in neutralizing chlorine free in chlorine treatment systems. Other common substances are used to treat chlorine and chlorine compounds including calcium sulfite and activated carbon or catalyst. The most effective filters use them in some combinations. What I can verify and check, is the ability of a bath filter to eliminate the total chlorine content of water flowing from your shower.
We have seen very little evidence that the most common type of shower filter has greatly affects the softness or hardness of water, or calcium accumulation. In fact, Some of the initial academic studies presented evidence that they did not. The shower filters we have tested also have very little effect on the total amount of solid solids in our water, according to measurements with TDS meters, such as filters that do not remove large amounts of materials or minerals from water.
I was unable to check the requirements of some companies that these filters removed heavy metals like lead and arsenic, fortunately not in my pipe. We only find a company, Weddell, with a certified filter to remove lead. So far, very good! However, if you believe that you have dangerous lead or arsenic in the country, maybe you should not try to fix the problem with a shower ordered by mail. Talk to a specialist of water treatment or your public health authority.
If you live in a big city of the United States, chlorine may not be what your city is used to treat water in its pipes. New York, Chicago, Seattle and Phoenix use chlorine, sure. But Los Angeles, Philadelphia, Atlanta, Boston and most major cities in Texas are not.
More than half of the major US cities use a substance called chloramine, a more stable and long -term chemicals that are harder to filter and check. That's what in my water supply. To check, I realized my convenience Digital water color meter And a slightly uncomfortable chemical index, and then check the capabilities of each shower filter to handle any chlorine compound in water.
First I checked the total chlorine in water without filtering, then I tried the water filtered with a shower. I have done many times each test to take into account the inaccuracy or fluctuations in the test and the city's chlorine level. In most cases, I did this for many days. When we update this tutorial, we will continue to check the most effective shower filters to see how their effectiveness changes over time and add any new shower filter we can introduce.
