Key Considerations: How To Select The Best Filter
Because shower heads are affordable and come in many different styles that match your bathroom decor, it’s easy to find a model that works with your budget. You can find a suitable shower filter for under $30 or over $75. It all depends on your needs, performance requirements, and the aesthetics of the filter.
What’s In Your Water
Make sure to test your home’s water source first, or check your local water quality report or EWG database so you can purchase the right shower filter for your specific needs. If you have limescale and hard water, certain filters will perform better. If you have chlorine or other contaminants, different filters will be best suited. Knowing what specific contaminant you are targeting will allow you to purchase the right filter without being disappointed the lack of results.
Check to see if the shower filter is NSF certified! You can do this in the NSF database or by looking at the manufacturer’s specs for their filter. The NSF certification is not mandatory, but it is an indication that the filter has been manufactured to the highest standards and will deliver on the manufactures promises.
The housing and filter casing is typically manufactured using quality BPA-free plastics. In some cases the housings will be made with metal like stainless steel, so make sure they are constructed with rust-free material.
The filters themselves will be created with various materials and media. The media should be packed solid enough to allow water to pass through without affecting your water pressure but not rattle and make a noise if you shake the filter. Higher-grade material means higher price tags. We discuss the types of filters in more detail below.
Some shower heads allow you to create a more powerful stream of water, while others allow you to decrease the stream for a more gentle shower. Other shower heads are designed to be adjustable.
Before purchasing your shower filter for hard water, determine what your current water pressure is with the shower heads you have, then investigate the shower heads you’re interesting in purchasing and determine if they are compatible with your home’s current water pressure.
The size and adjustability – wand-style shower head/filter combos require more water to travel through the hose and head – while adjustable shower heads change the amount and flow of water.The diameter of the shower head also determines the flow of water, which will significantly affect the water pressure.
No two shower filters are created equally, even if they contain the same media. Some shower filters last up to 6 months, others one year. Figure the cost of the replacement filters and upfront price to determine the total cost of ownership for the specific filter. Just because a filter has a lower price point, you may end up having to replace the filter more frequently, which can add up quickly.
More important to note is that the composition of your home’s water, the size of your family, and the number of showers taken per day will directly determine the filter life. If you’re using more water, you will have to replace the filter more frequently.
You may need a roll of plumber’s tape, but most shower filters include the installation kit and O-rings to avoid leakage. The positive with shower filters is they are a simple DIY installation that should take no more than 30 minutes to complete.
Read the packaging to determine the size of the housing. Most shower filter heads come with standard housing or adaptors, but not all homes use the same size plumbing. Make sure the filter is compatible with your current plumbing setup.
What Are Shower Head Water Filters?
Shower head water filters are point-of-use filters that attach to your existing shower plumbing. They are a cost-effective and user-friendly treatment method for reducing chlorine hard water minerals, and other contaminants that negatively affect your shower water.
Shower head water filters contain layers of filtration media. As water enters the shower filter head it comes into contact with the filter media to remove harmful impurities.
Your hair and skin are left shiny and healthy, and that filmy residue stops appearing on your shower doors. Shower head filters are designed so that only the water touching your face and body is fresh, healthy soft water.
How Do Shower Filters Work?
There are many different kinds of filtration media in shower filters that each serves a slightly different purpose. The filter can focus on hard water, chloramines, or adding back minerals to the water for healthier skin and hair. Here are the how the filter medias work:
- Kinetic Degradation Fluxion (KDF) Filters: KDF redox – the reduction of one molecule that leads to the oxidation of another – is a process which exchanges healthy electrons with harmful contaminants. This “give and take” converts the contaminants into harmless particles.
- Carbon Filters: You want to consider a shower filter for hard water that includes Activated Carbon filtration. This type of filter uses absorption to treat the water. As contaminants in your home’s water pass through the shower filter, activated carbon grabs and holds on to them, and letter pure filtered water passes through and onto your skin!
- Vitamin C Filters: As your home’s water enters the shower head filtration system, potent Vitamin C attacks the harmful chemicals and toxins. The stream of water is as pure as a mountain stream, and this extra treat of health benefits to your hair and skin is worth considering.
- Multi-Stage Filter System: For well water and local municipality sources, the best way to ensure you’re getting the best water filtration for your home and shower is to consider a multi-stage shower filter system for hard water. These shower filter systems work in two ways. An upstream pre-filter traps chemical contaminants and protects the more sensitive filter membrane against damage. An additional carbon filter or polishing filter works downstream to eliminate all the residual chemicals and metals not trapped in the first filtration process.
Types of Shower Filters
- Shower Head Filter: This shower head should soften your home’s water with activated carbon and use filtration media to remove impurities like lead, rust, and calcium. Ensure the filtration media chlorine and fluoride for an overall cleaner shower and bathing experience. Most of all, look for a shower head with at least four layers of filtration media to help make making the water much less harsh. You want your shower to leave your skin and hair significantly softer.
- In-line Shower Filter: This type of shower filter attaches to 1/2 inch shower arms – the spigot attached to the shower wall – without adding additional length. In-line shower filters reduce harsh chlorines and other chemicals in both well and tap water
- In-Line Shower Head Filters: Like it’s contemporary, this type of shower head features a spa-like shower head or adjustable settings. In-lin shower heads with multiple replacement heads or a custom-designed shower head still work as hard as regular shower filters for hard water, but don’t compromise or cheat you out of the exhilarating bathing experiences you like. Treat yourself!
- Shower Head Filter With Wand: For the ultimate water-filtered shower experience, shower head wands let you remove and grip the shower head and bathe comfortably in a fluid 360° motion. Putting the water where you want it while the built-in technology and filter media work hard to trap the chemicals, harmful metals, bacteria, and viruses.
Benefits Of Using A Shower Water Filter
Healthier Skin And Hair
Shower filters for hard water help control dandruff. Your scalp can easily fall victim to your home’s hard water. Calcium and Magnesium don’t dissolve easily. Science has shown that hard water combined with shampoo and your favorite soaps and body wash combat one another. The result is fewer luxurious suds, a waste of money, and that infamous scaly mineral film that dries our hair, flakes the skin on the scalp to uncontrollable dandruff, and makes our nails brittle.
Because shower water filters are point-of-use water filters, they are a very cost-effective water treatment option relative to a whole house water filter or water softener. They are also much easier to install, which saves money on potential installation costs that could be required for a whole house system.
Reduce Limescale and Water Spots
Hard water minerals like calcium and magnesium wreak havoc on shower heads and leave an unsightly film on shower doors. A shower water filter for hard water can effectively reduce the negative effects of hard water. After installation, you won’t have a slimy feeling or have to constantly clean the scale buildup.
Effective At Removing Chlorine
While many water municipalities add chlorine and chloramine to help kill harmful organisms that can potentially make us sick, it is also important to remember that filtering out Chlorine at high levels is beneficial to your health, your skin, and your lifestyle. Exposure to low levels of Chlorine may result in common respiratory irritations. At higher levels, chlorine exposure results in breathing rate changes, severe coughing, and even lung damage. Shop for a shower filter for hard water that is NSF/ANSI tested Standard 177 to reduce Chlorine.
Works With Well Water
Well water is known to contain high levels of harmful minerals, metals, pesticides, bacteria and viruses. It requires thorough and regular water testing and a filtration system to combat the bad stuff and offer you and your family the freshest, purest water possible. It is important to determine what contaminants in your well water test exist and at what levels and that the claims the shower filter for hard water match to ensure you’re taking a healthy shower. In some cases well water can be heavily contaminated in which case you would need a whole house well water filter or softener for well water.
Removes “Rotten Egg” Smell
Sulfur and Arsenic leach into water sources at many levels in both well and municipality water sources. No level is okay. You’ll know when Sulfur is present if you’re smelling the aroma of eggs. Sulfur makes your home’s water taste and smell horrible.
Arsenic levels above ten parts per billion (ppb) can lead to thickening and discoloration of the skin, numbness, and nerve pain. If you test your water and discover Sulfur or Arsenic at higher levels than recommended (no level is good), be sure your shower filter for hard water contains media that can remove these harmful elements.
Reduce Bacteria And Viruses
If you stop to think about Bacteria and Viruses in your home’s water, it most likely grosses you out. If you aren’t regularly testing your home’s water, or are educated on your local water table, every time you reach for a glass of water or turn on and step in the shower, you should be concerned about E. Coli, Hepatitis B, Salmonella, and Giardia. And don’t forget agricultural runoff and sewage.
Bacteria and viruses can infiltrate local water and well systems. Stop these harmful and potentially deadly levels from entering your home and disrupting your shower. Shop for a shower filter for hard water that includes a KDF55 media filter composed of high-purity copper/zinc granules.
Negatives Of A Shower Water Filter
Not A Whole House Solution
If you have hard water, chlorine, or sulfur smells, chances are it affects your entire home. A shower filter will help for a single point of use, but it won’t solve those issues anywhere else. If you have those problems, a whole house water filter or water softener is likely the best way to go. A whole-house solution will treat every drop of water that comes into your home, including all showers.
Shower head filters require regular filter replacements. These generally are not too expensive and don’t take long to change, but it is something to keep in mind. Filter options that require more frequent replacement can add up quickly.
FAQs For Shower Water Filters
