If your home has hard water, bad hair days aren’t the only concern. The scale deposits from hard water also wreak havoc on a home’s plumbing, water heater, dishwasher and more. A whole-house water softener is the best fix, but the systems can cost thousands of dollars, plus they need to be serviced annually by a professional.
Enter the shower filter. This relative newcomer to the water filtration category is a cost-effective way to treat just the water coming from your showerhead, the same way an under-sink filter only tackles water from the kitchen faucet. Shower filters remove minerals like magnesium and calcium that result in hard water, which prevents soap and shampoo from forming a rich lather.
Most shower filters also reduce the chlorine that's used in many municipal water treatment facilities. "At higher levels, chlorine is known to be drying and can lead to a rash on the skin known as contact dermatitis (a type of eczema)," says Joshua Zeichner, M.D., the director of cosmetic and clinical research at the Mount Sinai Hospital Department of Dermatology.
To find the best picks for your shower, our experts in the Good Housekeeping Institute's Home Improvement & Outdoor Lab evaluated more than a dozen shower filters covering a range of budgets and shower types.
