best shower water filter

Why do you need to buy the best shower water filters?

Almost all cities use chlorine to treat their water supply. While this is useful for reducing bacteria in the water, much chlorine remains in the water piped into your home.

Recent research show that in the steamy environment of a shower, this chlorine may be inhaled directly at concentrations which are many times greater than drinking the same water, and may pose a significant risk.

Although we think of a shower as refreshing and cleansing, a surprising amount of harmful chemicals can be easily absorbed through the skin. The best shower water filter can remove chlorine and other harmful chemicals providing you with healthy filtered water for showering.

There are a lot of shower water filters on the market these days, but how do you know which one to buy? Will it work with your existing shower plumbing? How much do replacement filters cost? Is it hard to install?

Should I Filter Bath Water?

We know it’s important to filter our drinking water, but why would you want to filter bath water too?

“A Professor of Water Chemistry at the University of Pittsburgh claims that exposure to vaporized chemicals in the water supplies through showering, bathing, and inhalation is 100 greater than through drinking the water.”
The Nader Report, Troubled Waters on Tap – Center for Study of Responsive Law

Shower  filters are a great way to ensure that the water you use for bathing and showering is pure and free from contaminants. Though the United Sates is known for having one of the most advanced water systems worldwide, there are still many harmful chemicals that make their way into the water that flows through the pipes in our homes.

The best way to determine what types of chemicals are lurking in your water is to have your water tested. If you are concerned regarding chemicals such as arsenic or chlorine in your water, then you might find that installing filters is the best way to protect yourself.

When choosing the best water filters you can select between models that filter all of the water throughout your home, or the water that is only flowing through your shower.

  1. Filters that work for your entire home are called whole house water filters.
  2. Filters that only work for one appliance are known as single source water filters.

If you apply shower  filters only to your shower, then you are installing single source water filters. Before choosing a water filtration system, you should compare the differences between whole house and single source filters to determine the best filtration methods for your needs.

Single source filters, provide the advantage of being more cost effective than whole house water filtration systems.

Since shower filters that are only used on the shower are more economical, they ensure that all homeowners or apartment dwellers can ensure that they have clean water when taking a shower.

When choosing the best shower water filters you will need to determine how often the filter will need to be changed or replaced. They typically work by allowing the water to filter through copper or zinc materials to reduce the amount of other negative chemicals and restore the water’s PH balance.

For those who are concerned about the health of their water you can use these types. The best way to determine if your water needs filtering is to have it tested.

There are several benefits to testing your watery. First, you’ll be able to identify if you need shower water filters or other filtration systems and second, you’ll be able to identify any specific impurities in the water.

By knowing exactly what chemicals are present in your water, you’ll be able to choose a purifying or water filtration system that best removes those specific chemicals.

Why Should you Use the Best Shower Water Filters?

Clearly, there are good reasons to filter your bath water:

1. HAIR – Often referred to as a woman’s “crowning glory”, meaning a praise worthy asset.

best shower water filterWe spend so much time on our hair, but we don’t always get the look we want.  Dry, frizzled, brittle, thinning and/or dull hair is not the look we want.  Simply put, dry hair ages you.  Let’s see how it happens and how it can be repaired.

When you are washing your hair in the shower, the warm water opens the cuticle of each hair shaft. (Think of the cuticle as tiny scales covering the length of each hair.) It forms a protective casing and, when healthy, and makes the hair shiny and resilient.

As you wash your hair in water containing chlorine and other toxic chemicals, the proteins and the delicate cuticle are damaged or destroyed.

And to add insult to injury, your hair stays coated in the chlorinated water you rinse in. It’s no wonder that your wet hair is a tangled, matted and frustrating mess!

Simply changing to the best shower filter will reverse the process and give your hair a chance to heal.

The chlorine will be fully rinsed from your hair after a few washes. But you will be able to feel and see the difference after your first chlorine free shampoo.  The important minerals, potassium and magnesium, are retained in the second stage of the water filtering process.  Ph is also balanced to the healthy level.  And finally, your hair products will bond better to truly clean hair.

The best shower filter is under $70 and easy to install, even with “girl tools.” See the video at the bottom to see the ease of installation.

If you have had the popular keratin treatment to smooth and staighten your hair, it is imperative to use the best shower filter when you shampoo.  The chlorine can damage the expensive keratin you just paid for!

Supermodel Carol Alt was recently on the Dr. Oz show.  She shared her secret for her amazing hair.  Guess what??  A showerhead filter!  She too found that hair products work better with truly clean hair.  And, you will too!

 2. It’s unhealthy to drink chlorine

But there’s also a problem with chlorine in the water you bathe in. While bathing, water gets absorbed into your body. The chlorine soaks in with it. Hot water will open pores which allows more chlorine to be absorbed.

Chlorine will also damage your hair, dry out the natural oils in our skin, and make you feel dry and itchy.

“Ironically, even the Chlorine widely used to disinfect water produces Carcinogenic traces. Studies indicate the suspect chemicals can also be inhaled and absorbed through the skin during showering and bathing.”
U. S. News & World Report – 29 July 1991, Is your Water Safe – The Dangerous State of Your Water

2) When you’re taking a bath, hot water releases chlorine gas into the air, trapped in the bathroom with you, so you end up breathing it in. In addition, when you’re finished bathing, the chlorine will vent out and contaminate the air in the rest of your home.

“A long, hot shower can be dangerous. The toxic chemicals are inhaled in high concentrations.”
Bottom Line – August 1987, J Andelman, Ph. D

3) The above also applies to a lot of the other toxins and chemicals known to be in our municipal tap water. Like chlorine, these toxins will also vaporize in a steamy, hot bath, forming a gas. Naturally you’ll breathe in that gas too.

Here are some other bonus benefits you will get with the best shower filter:

1-     Your air in the bathroom will be cleaner.  Chlorine releases chloroform gas into the air when your water reaches a warm temperature.

2-     The bathtub and shower stay cleaner.  Soap scum, mildew and fungus don’t adhere to truly clean surfaces.

3-     No more red, stinging eyes.  Removing the chemicals leaves only fresh, healthy water.

4-     Your hair products will bond better.  Maybe you will even be able to style your hair like a pro!

5-     Quick shipping and  a 100% satisfaction guarantee.  Best Buy from Consumer’s Digest, too.

One low cost purchase will give you a lifetime of clean water in your shower.  There is a handheld option that is good for bathing children and even your pets. You can feel good about tossing the contaminant filled filters into your re-cycle bin.  Installation is easy to do by yourself.  Instructions are included and there is even a video on the internet to show you how.

Filter The Water You Bathe In

The best solution: a whole-house water filter will remove 99.99% of the chlorine and other toxins. A whole-house system doesn’t come cheap though. The system which offers the best value for money is the Aquasana Rhino, which will cost you about $800.

The next best solution: fill your bath using a shower water filter.
