You may want shower filters for hard water, but you also want to remove hazardous chemicals that vaporize during a hot bath. In the enclosed area of the bathroom, we inhale these chemicals and scientists believe that increases our risk of cancer.
You also want to remove chlorine, if it's present. Chlorine also vaporizes and inhalation is irritating to the sinuses, as well as the entire respiratory system. The chemical vapors are known to trigger asthma attacks. That's one reason that indoor swimming pools are closed if chlorine levels climb too high.
The best shower filters for hard water combine ion exchange to balance mineral content and soften. This step also removes traces of metals like lead and copper that seep in from the pipes. Metallic traces dull the hair and exposure to lead is never safe.
Granulated carbon will remove chlorine and some of the other chemicals, but a process called adsorption is needed to remove as many chemicals as possible. Specifically, it removes chlorination byproducts. Those are the ones that cause cancer.
The prices of shower filters for hard water vary greatly. Believe me. You don't need the most expensive product on the market to get the best performance.
Some people recommend reverse osmosis. That's an expensive and largely unnecessary step, even for drinking water filtration. It also creates gallons of wastewater and there are no units specifically designed for your showerhead. You'd have to get one for the whole house.
Whole house filters are sometimes a good idea, but generally speaking, your showerheads and your kitchen faucets are most important. There's no particular reason to filter the waters for the toilet or even the laundry. You can always add water softeners to the laundry.
Some people recommend a brand called Wellness. There's no real reason to go to that expense, either. They make some scientific claims that they can't back up with hard evidence. There biggest claim to fame is that they are supposedly used in the number one health spa in the world, but I couldn't verify that, either.
The best shower filters for hard water have been evaluated and rated by Consumer Reports. The company provides certified product performance data before you buy. The cost of use is pennies a day and the replacement filter lasts a full six months.
In case you have a hard time remembering when it's time to change your filter, the company offers automatic shipment and discounts for signing up. There are many ways to save money. Buying direct from the factory is one easy way.
You want a product that is easy to install and unlikely to leak, simply to avoid frustration. If you're tall, you also want one that does not reduce the height of the showerhead.
The right shower filters for hard water will protect your health, as well as prevent that scaly build up on your bathroom fixtures. Just be sure to shop carefully, so that you don't end up disappointed.
