How Do Shower Filters Work?

Shower filters get rid of impurities in water, such as chloramine and chlorine that are added by the local treatment plant.

Also, it kills the bacteria and germs that are present in the pipes underground and your home's plumbing. They do this by installing filtration media such as KDF in the shower heads.

When water is filtered, skin irritants that damage your hair or skin are targeted before they can come out of your shower.

It's proven how water filters can save lives from illnesses, skin infections, and death. And shower filters aren't different. It double filters the water that you are using.

But what exactly are these chemicals and impurities that it eliminates and how does it affect our health when consuming them while taking a bath? And what types of water filtration can you use to be safe? Let's discuss them one by one. 

Chemicals That Shower Filter Eliminates

These are the two major substances used for cleaning the water that is targeted by shower filters; chlorine and chloramines.

Although they're excellent at turning wastewater into consumable and usable liquid again, they still need to be filtered out even more to ensure the health of the person who'll use it. 

Chlorine 

Chlorine is used as a disinfectant to destroy water-borne pathogens that are harmful to human health and carry illnesses such as diarrhea, skin rashes, etc.

However, although it's a powerful ingredient that changed the world, it damages your skin, nails, and hair by washing away their natural oil. As a result, it becomes brittle and dry when entering your pores. 

Chloramine

Chloramine does the same work as chlorine but is weaker. It is a chemical variant of chlorine with ammonia added.

However, chlorination is the last step of the water treatment process before distribution to ensure the removal of leftover germs. Another chloramine increases the lead that's present in water.

Along with that are these health problems caused by exposure to chloramine present in the water.

  • Skin problems such as rashes, scaling, dryness, erupting and feeling of chemical burning
  • Nasal congestion
  • Itchy and swollen eyes
  • Stomach ache
  • Yeast infection
  • Sneezing
  • Coughing

Chlorine Vs. Chloramine

Although they're both used as water disinfectants, there are small differences between the two. 

  • Chlorine is less corrosive on pipes. 
  • Chloramine has less odor and taste.
  • Chlorine stays active for a shorter period in water. It loses its effect faster as the treated water travels through pipes.
  • Chloramine is harmful to the environment. Also, it can be absorbed by fish and may cause death. 

Types Of Water Filtration

After the killing and the treatment of the public water systems, here are the two main types of water filtration.

There is a built-in filter shower, which lets you simply replace the shower head. And there is an in-line shower filter which is installed between the waterline and the shower head.

Its variation in technology includes the following:

  • Granular activated carbon filters - Mostly used in traditional water filtration systems, this removes certain chemicals that give foul odor and taste to water like chloride. Also, it attracts and absorbs chlorine and can perform best in cold water. This cannot kill iron and nitrate, so you will need a separate or another filter for that.

  • Vitamin C media filters - This water filter uses natural vitamin C to neutralize chlorine and other toxins from the water. However, it's not capable of washing out other harmful elements that are present.

  • Kinetic Degradation Fluxion (KDF) - made up of zinc alloys that change contaminated water into harmless materials like chloride ions. It can kill bacteria, rust, pesticides, fungi, iron, nickel, lead, foul odors and tastes, and more organic compounds found in water.

  •  Shower water softener - It makes hard water soft and reduces the amount of calcium and magnesium that are present in the water. You know that you have hard water when your hands still feel soapy after washing. It breaks a layer of your skin that keeps it moisturized, which is why the ion exchange that's made in this water filter is important.

Is Shower Filter Worth It?

If you are living in areas with low water quality and if your skin lies under the sensitive types, having a shower filter installed in your bathroom is a terrific choice for your family's health.

Here are other advantages that you can get from having this water technology in the comfort of your home. 

  • It can remove bacteria that clogs or is present in your shower head. This means your head can catch all of those unwanted bacteria and microorganisms that can make you sick. 
  • Reduces the risk of cancer. Researchers found that there are new toxic and carcinogens present in the treated water (which is mainly cleaned with chlorine) in America. So reducing the amount can prevent your family from getting cancer. 
  • It can make your skin condition better. Chlorine and other contaminants such as lead and chloramine that causes wrinkles or skin dryness can penetrate your skin. Especially if you are showering with warm or hot water since it opens up the pores in your body.

Does Shower Filter Stop Hair Loss?

Yes, having your water flow through filters when showering can help aid hair loss since chlorine can rip out sebum, the natural oil that protects our hair. Keep it moisturized and healthy. Having a little amount of this "oil ripper" can save your scalp from damage.

Does Shower Filter Affect Water Pressure?

Yes, a shower filter can affect water pressure when it's installed incorrectly. It can withhold water pressure and has a rating that usually estimates between 20 - 100 PS or a private sewer line. If a water filter's affected, these are most likely the reasons why:

  • Low flow shower head
  • Clogged shower head
  • Worn out mixing valve
  • Faulty water pressure regulator
  • Closed valve
  • Corroded or leaking pipes

Yes, this task requires beginner skills and you can execute it within an hour. If you are planning to install this yourself, here are the steps that you should follow, depending on the type of shower filter.

How To Install In-Line Shower Filter

First, remove the shower head by rotating it counterclockwise until it is detached from the arm completely. Remove any plumber or Teflon tapes that are still wrapped around the shower arm and replace them with a new one.

Next, attach the shower filter to the shower arm tightly. Using pliers, turn the nut a little bit more, but not too tight. 

Clean the inside of the filter by opening the cold water and leaving it to flow out for 5 minutes.

Once that time passed, turn the temperature to hot water and leave it again for the same amount of time. This will make sure that any dirt or packaging residue stuck inside gets washed out. 

Get the shower head you detached earlier and connect it back to the shower arm and filter. Open the water again to check if there is a leaking or a malfunction.

How To Install Built-In Shower Filter

Disconnect the shower head and proceed to clean the shower arm. Remove any residue before wrapping a new set of plumber's tape. Set that aside and get the built-in filter. Place it directly under the faucet and let cold water run through it for 10 minutes.

Secure the filter and connect it to the shower arm using a clockwise direction. Once it's tight enough, test the water flow if everything is alright.
