If you happen to spend sufficient time on Instagram, you would possibly start to get the concept the most important drawback dealing with America in the present day is water, and what’s in it.
Over the previous few years, a brand new era of fashionable filtered showerheads has arrived to hijack our collective social media feed—and presumably our unconscious—with a terrifying query.
Can you actually belief the water that comes out of your bathe?
The makers of those showerheads are inclined to make daring pronouncements about what your deteriorating pipes and chemical-filled bathe water is perhaps doing to your physique, throughout what might in any other case be the one peaceable 5 minutes of your day. If you happen to can rid your self of the chlorine or contaminants in your water, the argument goes, it might be the remedy in your most embarrassing issues: every part from frizzy hair to limp hair to dandruff, hair loss, eczema, dry pores and skin, break up ends, blackheads, and the heartbreak of psoriasis.
However many filtered showerheads are fairly good at eradicating the abrasive chlorine compounds that cities add to your faucet water to kill micro organism. And so this was our focus. About half the nation’s water programs, together with New York and Seattle, use chlorine to disinfect the town’s water provide. However most main metropolitan areas use a extra secure substance known as chloramine that’s considered much less carcinogenic. However chloramine is tougher to filter out—and never all bathe filters succeed.
Actually, the variations in efficiency have been shockingly large in some instances. So, let’s say you don’t like chlorine in your water? And you reside in a metropolis? These are the showerheads we suggest.

How We Examined and What We Examined
We solicited unbiased lab information from the makers, the place it existed. We additionally used digital and chemical assessments designed for swimming pools and aquariums and averted painfully unreliable dwelling check strips. The upshot is that you simply in all probability shouldn’t count on these bathe filters to melt the mineral hardness of your water or take away most substances.
So what do these showerhead filters truly do, in a method we will measure? They filter chlorine and chlorine compounds, principally via chemical reactions. Just about each American metropolis provides low concentrations of chlorine or chlorine compounds to ingesting water to kill doubtlessly dangerous micro organism. That is all effectively and good when the water’s nonetheless within the pipes. However chlorine’s not precisely nice in your hair or your pores and skin, and few individuals prefer to drink it. Some are additionally particularly delicate to the style or odor, or vulnerable to pores and skin reactions.
That’s the place dwelling filters are available in. Probably the most distinguished bathe filters rely partly on a zinc-copper combination known as KDF-55, recognized to be fairly efficient at neutralizing pure or “free” chlorine. Different frequent substances used to deal with chlorine and chlorine compounds embrace calcium sulfite and activated carbon. The simplest filters use these in some mixture.
What Bathe Filters In all probability Don’t Do
The marketplace for filtered showerheads stays younger and largely unregulated, and efficiency claims are solely not often backed up publicly by unbiased information. We made plenty of requests, however few bathe filter corporations hand over their lab outcomes. (Thank you, Aquasana, for being an exception.)
Some makers instructed us that unbiased labs and certifying our bodies have been backed up, and that information is forthcoming. Many provided buyer satisfaction surveys as an alternative. This all implies that some skepticism is warranted.
In spite of everything, a filter should be comparatively small to suit right into a showerhead. And but it’s being requested to filter gallons of water every minute, pushed out at each excessive temperature and excessive stress. A showerhead filter poses a frightening engineering problem, as in comparison with countertop water filters that deal with solely a small quantity of water at a time—or a cumbersome reverse-osmosis gadget that may plug into your under-sink plumbing.
We’ve seen little proof that the most typical sorts of showerhead filters have a lot impact on the softness or hardness of water, or on calcium buildup. Actually, some early academic studies present evidence that they don’t. The bathe filters we examined additionally had little or no impact on the sum complete of dissolved solids in our water, in keeping with measurements with a TDS meter—i.e., the filters aren’t eradicating a considerable amount of supplies or minerals from the water.
I wasn’t in a position to check claims by some corporations that these filters take away heavy metals like lead and arsenic, which fortunately aren’t in my pipes. However for those who imagine you’ve harmful lead or arsenic in your water, you in all probability shouldn’t attempt to repair the issue with a mail-order showerhead. Speak to a water therapy skilled or your public well being authority.
If you happen to reside in a significant US metropolis, chlorine is probably going not what your metropolis makes use of to deal with the water in its pipes. New York, Chicago, Seattle, and Phoenix use chlorine, certain. However Los Angeles, Philadelphia, Atlanta, Boston, and most large cities in Texas don’t.
Greater than half of American large cities use a substance known as chloramine, a extra secure and enduring chemical that’s tougher to filter and check. To check, I acquired out my helpful digital water colorimeter and a considerably nasty chemical indicator, after which examined the flexibility of every bathe filter to deal with chlorine compounds within the water.
First I examined the full chlorine within the water with none filtering, then I examined the water filtered by the showerhead. I did every check a number of occasions to account for imprecision or fluctuations in municipal chlorine ranges. Normally, I did this over a number of days. (One showerhead’s filter broke from its personal weight on the second day of testing. I felt snug not recommending this showerhead, regardless of solely someday of middling check outcomes.) As we replace this information, we’ll proceed to check the best showerhead filters to see how their efficacy modifications over time—and add any new bathe filters we’re in a position to suggest.
