Let‘s start by looking at why filtering your bath water is so beneficial in the first place.

Why Filter Your Bath Water?

According to a survey by the Water Quality Association, 46% of Americans rely on baths as their primary source of relaxation. But the tap water filling your tub can contain a surprising array of contaminants:

Chlorine – Skin irritant added to public water systems

Heavy metals – Lead, mercury, aluminum and more

Bacteria and viruses – Such as E. coli, salmonella, Legionella

Pesticides and herbicides – From residential lawn runoff

Pharmaceuticals – From human waste streams

VOCs – Volatile organic compounds released from plastics

Exposure to these substances, even in small amounts, can lead to:

• Dry, itchy skin
• Hair damage and breakage
• Respiratory irritation
• Allergic reactions
• Chemical absorption

According to a study in the International Journal of Environmental Health Research, bathing in contaminated water for just 15 minutes allowed significant chemical absorption through the skin.

Filtering your water can prevent all of this by trapping contaminants before they enter your bath. Let‘s look at the different filtering options available.

Types of Bath Water Filters

There are several different ways you can purify the water that fills your tub:

In-Line Bath Filters

In-line filters get installed along the main water supply line that fills the tub. As water flows through the unit, contaminants get caught in the filter.

Most in-line filters use a multi-stage system combining:

Sediment pre-filter – Traps particulate matter like dirt, rust and sand

Activated carbon filter – Adsorbs chemicals, VOCs and heavy metals

Optional extras – Ion exchange, biocides, UV sanitation, reverse osmosis

Benefits:

• Filters all incoming bath water
• Installs permanently out of sight
• Can filter entire home supply

Considerations:

• Installation can be complex
• Higher upfront cost

Faucet Mount Filters

These small filters attach directly to your tub‘s faucet spout. Water flows through the filter before entering your bath. Carbon filtration is typically used.

Benefits:

• Simple and inexpensive
• Easy DIY installation
• Small profile doesn‘t clog drains

Considerations:

• Only filters a portion of water
• Cartridges require frequent changes

Portable Bath Ball Filters

These floating plastic balls contain a filtration media like activated charcoal. As the ball bobs around your bath, it slowly releases purified water.

Benefits:

• Very affordable
• No installation needed
• Take it anywhere

Considerations:

• Limited per use capacity
• Can clog drains if sucked underwater

Mineral Salt or Essential Oil Soaks

Rather than filtration, you can purify bath water by adding mineral salts or essential oils. Salts soften water while oils have antiseptic properties.

Benefits:

• All natural ingredients
• Provides therapeutic benefits

Considerations:

• Effects less comprehensive than filtration
• Improper dilution can irritate skin

Okay, now that you know the main options available, let‘s go over how to select the right bath filter for your needs.

Choosing the Best Bath Water Filter

With so many filtration methods to pick from, it‘s important to consider:

• Filtration effectiveness – Does it remove the specific contaminants concerning you?
• Installation requirements – Pick a filter you can install properly yourself or will need professional help.
• Convenience factors – Frequent cartridge changes may be a hassle for some options.
• Flow rate – Ensure your filter doesn‘t restrict the tub fill spout rate.
• Added features – Some have built-in lights, volume control, etc.
• Budget – Filter costs range from $10 to $300. Factor in ongoing costs too.

Once you‘ve compared the options, it‘s time to get your bath filter installed.

Installing Different Types of Bath Water Filters

Installation typically only takes about 30 minutes. Always follow the manufacturer‘s instructions closely.

Installing In-Line Bath Filters

1. Turn off main water supply and open tub faucet to drain pipes.
2. Cut into supply line at desired install point.
3. Connect filter unit to supply lines using provided fittings.
4. Secure filter in place under sink or tub.
5. Turn water back on and check for leaks.
6. Flush filter per instructions.

Installing Faucet Mount Filters

1. Unscrew and remove existing aerator from faucet spout.
2. Screw diverter valve onto spout if included.
3. Attach filter directly onto faucet spout threads.
4. Turn on water and check for leaks at filter connections.

Using Portable Bath Ball Filters

1. Open ball and fill with provided filtration media, typically activated charcoal.
2. Seal ball halves back together per directions.
3. Toss ball into tub as it fills and allow to float and slowly filter.

Adding Mineral Salt or Essential Oil

1. Draw bath water as normal.
2. As tub fills, add:
   • 5-10 drops of essential oil
   • 1-2 cups mineral or Epsom salt
3. Agitate water gently to dissolve and disperse.
4. Soak and enjoy purified bath!

Be sure to follow all usage and safety directions provided with any bath filter or additive. Now let‘s go over how to maintain your filter.

Caring for Your Bath Water Filter

To keep your bath filter working efficiently:

• In-line filters – Replace cartridges every 6-12 months. Inspect lines for leaks.
• Faucet filters – Change cartridges every 2-3 months. Disinfect housing regularly.
• Bath balls – Recharge charcoal every 1-2 months. Replace balls every 6 months.
• Salts and oils – Replace annually to replenish potency.

Always follow your specific product‘s maintenance guidelines. If flow becomes restricted, change cartridges immediately.

The Effectiveness of Bath Water Filters

The contaminants removed by a bath filter depends on its filtration media and technology:

• Sediment – Traps particulates like dirt, sand and rust.
• Chlorine – Reduces exposure to this common skin irritant.
• Heavy metals – Filters out lead, mercury and other hazardous metals.
• Bacteria/viruses – Some filters utilize disinfection to kill pathogens.
• Hardness minerals – Reduces amounts of calcium and magnesium.
• Odors – Adsorbs unpleasant sulfur smells.
• Dyes/colors – Removes artificial dye colors added to water.

While filtration is very effective, it cannot remove every potential bath water pollutant like fluoride, pharmaceuticals or asbestos fibers. When in doubt, have your water tested by a certified lab.

Extra Bath Water Purification Methods

In addition to filtration, consider trying these methods to naturally purify your bath:

• Bath bombs/melts – Fizzy, moisturizing bombs with essential oils and butters.
• Baking soda – Balances pH and leaves skin and hair silky.
• Apple cider vinegar – Just 2 tablespoons balances pH for shiny hair.
• Hydrogen peroxide – Kills germs and whitens tile grout.
• Sunlight – Harnesses UV rays to naturally kill bacteria. Consider an outdoor bath!

Cost Comparison of Bath Water Filtration Options

To help decide which method fits your budget:

• Faucet mount filters start at $10-15
• High-end in-line systems can cost $200-300
• Replacement cartridges range from $5-40
• Mineral salts and essential oils cost ~ $1-5 per use

While filtration requires an initial investment, it can actually save money over time by preventing problems like skin rashes and hair damage that result from bathing in contaminated water.

Staying Safe With Your Bath Water Filter

Bath filters provide many benefits, but be sure to keep these safety tips in mind:

• Monitor water temperature carefully to avoid accidental scalds.
• Supervise young children during baths, as filters could pose a drowning risk.
• Inspect for leaks, damage or clogs that could lead to flooding.
• Follow all manufacturer instructions for installation and operation.
• Consider consulting a professional if you have any installation concerns.

Relax in Fresh, Clean and Healthy Bath Water

In my opinion as a passionate DIYer, there‘s nothing better after a long day than a warm, soothing bath. But I don‘t want to steep in a soup of nasty contaminants! That‘s why filtering my bath water is a must.

The various filtration options available make it easy and affordable to purify your bathing experience. Just think – soak in water free of chemicals, metals, bacteria and other gross stuff for better health and home enjoyment.

I hope this guide gives you all the details needed to choose the right bath water filter, install it properly and maintain it for a lifetime of refreshing, uncontaminated baths. Let me know if you have any other questions!
