11 Shower Filters For Healthier Skin & Hair in 2024

What exactly is a shower filter, and how does it work?

A shower filter is a device that attaches to your showerhead and purifies the water before it comes into contact with your skin and hair. 

Its primary purpose is to remove harmful contaminants such as chlorine, heavy metals, and bacteria from the water, thereby providing a healthier and more pleasant showering experience.

Shower filters work by employing a combination of filtration technologies. Common methods include sediment filtration for removing particles like dirt and rust.

Carbon filtration for absorbing chlorine and other chemicals, and specialized media such as KDF (Kinetic Degradation Fluxion)or vitamin C for targeting specific contaminants.

By effectively filtering out these unwanted substances, shower filters can contribute to improved skin and hair health, reduce the risk of irritation, and provide a more refreshing and enjoyable shower.

Installing a shower filter is a simple yet effective way to enhance the quality of the water you use daily.

What are the different types of shower filters?

Shower filters come in two main categories: inline filters and in-head filters. Let’s take a closer look at each type and how they differ.

Inline Filters

Inline filters are installed between the showerhead and the water supply line. They offer a larger filtration area compared to in-head filters, allowing for more comprehensive filtration. 

The advantages of inline filters include:

• More thorough filtration due to the larger surface area. 
• Compatibility with various showerhead types and designs. 
• Easier maintenance and filter replacement. 

In-Head Filters

In-head filters are integrated directly into the showerhead itself, providing a compact and discreet filtration solution. 

The advantages of in-head filters include:

• Space-saving design, ideal for smaller showers. 
• Easy installation without the need for additional hardware. 
• Aesthetically pleasing, as the filter is hidden within the showerhead. 

What features should you look for in a good shower filter?

Contaminant Removal Capabilities

One of the most important factors to consider is the filter’s ability to remove the specific contaminants present in your local water supply. 

Research the most common water issues in your area and look for a filter that targets those contaminants. 

Additionally, check for certifications from reputable organizations like NSF International or the Water Quality Association (WQA), which verify the filter’s performance in removing specific pollutants.

Filter Media Types

Different filter media types are designed to remove various contaminants. 

Granular activated carbon (GAC) is effective at removing chlorine, chloramines, and organic compounds, while KDF media is known for its ability to reduce heavy metals, bacteria, and algae. Vitamin C filters, on the other hand, specialize in neutralizing chlorine and chloramine.

Consider a filter that incorporates multiple media types for more comprehensive contaminant removal.

Compatibility and Installation

Ensure that the shower filter you choose is compatible with your existing shower setup, whether you have a fixed showerhead, a handheld unit, or a rainfall-style head.

Also, consider the ease of installation; look for filters that can be installed without the need for professional help or special tools.

Water Pressure and Flow Rate

A good shower filter should not significantly reduce your water pressure or flow rate.

Look for filters that maintain a strong, steady flow, and check the product specifications for information on potential pressure drops. 

Keep in mind that some filtration media may slightly reduce water pressure, but high-quality filters should minimize this effect.

Filter Lifespan and Replacement

Consider the expected lifespan of the filter and how often it needs to be replaced. A longer-lasting filter can save you money and reduce maintenance in the long run. 

Some filters come with replacement indicators that signal when it’s time to change the cartridge, which can be a helpful feature.

Cost Considerations

Finally, the cost of the shower filter is factored into, including both the initial purchase price and the long-term costs of replacing filter cartridges. 

While a higher-priced filter may have a greater upfront cost, it could offer better long-term value if it has a longer lifespan or more efficient filtration. 

Also, keep in mind that a good shower filter can lead to potential savings on water and energy bills by reducing the need for lengthy showers due to dry skin or hair.

What certifications should I look for when shopping for a shower filter?

NSF International Certifications

• NSF/ANSI 177: This is the most relevant NSF certification for shower filters, as it specifically tests for chlorine reduction and material safety in shower filtration systems.
• NSF/ANSI 372: This certification ensures that plumbing products meet the “lead-free” requirements, which is important for maintaining water quality and safety.

Water Quality Association (WQA) Gold Seal Certification: Products with this certification have undergone rigorous testing and meet WQA’s standards for performance, safety, and environmental compatibility, giving consumers confidence in the filter’s effectiveness.

EPA (Environmental Protection Agency) Registration: While not specific to shower filters, EPA registration indicates that the product is safe for use and does not contain harmful chemicals, providing an added layer of assurance.

IAPMO R&T Certification: The International Association of Plumbing and Mechanical Officials (IAPMO) tests shower filters for contaminant reduction and compliance with plumbing codes, ensuring the product’s performance and compatibility with plumbing systems.

ASME A112.18.1 and CSA B125.1: These certifications demonstrate compliance with plumbing code standards, which is important for ensuring the filter’s proper functioning and safety.

California Energy Commission and Department of Energy Listings: Filters with these listings have been proven to meet water and energy-saving standards, making them an eco-friendly choice for consumers looking to reduce their environmental impact.

CUPC (Certified Uniform Plumbing Code): This certification ensures that the shower filter complies with plumbing code standards, providing peace of mind regarding its safety and compatibility with your plumbing system.

WaterSense Certification: Although not directly related to filtration, this EPA-backed program certifies water-efficient products. Shower filters with this certification can help conserve water while still providing an effective filtration experience.

How can you maximize the benefits of your shower filter?

• Regular Replacement of Filter Cartridges: Follow Manufacturer Guidelines: Replace your shower filter cartridge according to the manufacturer’s recommendations, typically every 3 to 6 months or after filtering approximately 10,000 gallons of water. This ensures optimal performance and filtration efficiency.
• Monitor for Signs of Wear: Look for signs such as decreased water pressure, unusual odors, or discoloration in your water, which may indicate that it’s time to replace the filter sooner.
• Use Vitamin C Infusion Cartridges: Enhance Filtration: Consider using shower filters that include Vitamin C infusion cartridges. These can help neutralize chlorine and provide additional skin benefits, such as hydration and reduced irritation.
• Maintain Proper Water Temperature: Avoid Extreme Temperatures: Use warm (not hot) water when showering. Extremely hot water can strip natural oils from your skin and hair, counteracting the benefits of the filter.
• Install Correctly: Ensure Proper Installation: Make sure your shower filter is installed correctly to avoid leaks and ensure maximum water flow through the filtration system. Follow the installation instructions carefully.

Can shower filters really improve hair color retention?

Shower filters can significantly improve hair color retention by reducing chlorine levels in your shower water, which is known to strip hair dye and cause color fading. 

Chlorine can bond with sebum, pulling it out and leaving hair dull and lifeless, while also weakening its structure. 

Many shower filters, such as Weddell’s and Jolie’s, effectively reduce chlorine, helping to maintain the hair’s natural oils and protein structure. Additionally, these filters can remove heavy metals and minerals that may affect hair color. 

Some models also feature Vitamin C infusion, which further neutralizes chlorine and protects color. Softer, filtered water helps retain moisture, enhancing overall hair health. 

While shower filters are beneficial for color retention, combining their use with protective measures like wetting hair before swimming and using color-protecting products can maximize results.
