This phenomenon “causes your pores to clog up, which, in turn, can lead to acne and exacerbate skin conditions like eczema and dermatitis,” Tess Mauricio, a board-certified dermatologist in Beverly Hills, previously told Real Simple. With your hair, “you may notice [your hair] lose its color and not look as shiny with long-term use of hard water.” All shower filters look pretty similar, but there are key specifications consumers should keep in mind before buying, including the type of filtration system, your shower type, and the filter’s longevity. Our top choice is the AquaBliss High Output Shower Filter, which removes both chlorine and chlorine byproducts and fits all shower head types. Read on to check out our top shower filter picks as well as how to choose the right shower filter for your home.

Filter Type: Built-inShower Head Type: HandheldFilter Life: Six months
Yes, you can still buy an inline shower filter if you have a handheld shower head. What’s so great about this filter is that you don’t have to attach it directly to your hose, which may make it heavier to hold. You can attach it to the wall elbow (the wall hook where you rest your handheld shower head) or you can also attach it to the shower valve, so you don’t have to see it while showering. The latter option is only recommended for DIYers who know some about plumbing, as your shower valve is hidden in your wall. The Kohler Aquifer Shower Filter works to filter out chlorine and any odor that may be coming from your water. It also controls the growth of scale, bacteria, and algae. This shower filter lasts about six months, or until you reach 8,000 gallons, and you can either purchase a new filter when it’s time or enroll in Kohler’s cartridge replacement subscription service, which automatically sends you a filter in the time frame of your choosing, including three, six, nine, or 12 months.

Filter Type: InlineShower Head Type: HandheldFilter Life: Six months
Even though it looks just like many of the other options on this list, CraterAquaSystem’s shower filter takes water purification to the next level with its KDF-55 layer. KDF-55 is a filtration process that prevents heavy duty impurities such as lead, mercury, iron, and more from reaching your shower. It is often used alongside activated carbon in shower filters, including this one, to achieve optimal filtration results. The KDF-55 present in this model is also able to control bacteria, dirt, algae, and fungi and reduces up to 97 percent of chlorine. This shower filter lasts about three to six months depending on use, or until you reach 12,000 gallons filtered. Unlike other shower filters, your order comes with two cartridges, so you won’t need to buy a new one for up to a year. Plus, it’s specifically designed to prevent leakage, so you don’t need to worry about water dripping out of the filter. Product Details:

How to Shop for Shower Filters
Type
There are two types of shower filters you should be aware of: inline and built-in. One doesn’t necessarily perform better than the other, so the biggest question you need to ask yourself prior to buying is what will work best in your shower. Inline shower filters are the best option for people who can’t replace their shower heads, such as renters, because they can be attached to any existing shower head. Built-in filtered shower heads are, as you might have guessed, shower heads that have a filter already built-in, and are ideal for people who can and want to replace their shower heads. Built-ins are available for handheld shower heads, too.
Filtration
Shower filters typically use two types of filtration systems: activated carbon and kinetic degradation fluxion (also known as KDF or redox media). Carbon filtration systems use activated carbon (also known as activated charcoal) to draw in and trap the contaminants present in your water, including chlorine, pesticides, lithium, and chlorine byproducts. Kinetic degradation fluxion systems use a mixture of copper and zinc to filter out contaminants such as lead, mercury, iron, chlorine, and more—it may even reduce limescale. These systems are often used with activated carbon to achieve the best filtration results. While browsing, you may see shower filters with a Vitamin C filtration system, which filter out chlorine and chloramine fluoride, but not much else.
Care
There isn’t a whole lot of maintenance involved with maintaining the life of a shower filter—the only thing you need to be mindful of is its lifespan. Shower filters tend to last about three to six months, though that may vary depending on the manufacturer and how often you take showers. Oftentimes the manufacturer will list the number of gallons it can handle before needing to be replaced. To figure out, consider the amount of time you are usually taking a shower, multiply it by 2.5 gallons (the amount an average shower head emits per minute), then divide by the maximum amount of gallons the shower filter can handle before it needs to be replaced.
Questions You Might Ask
Do I really need a shower filter?
It depends on your needs. Although you aren’t drinking shower water, it’s still covering skin and hair, and hard water can have a negative impact on both. Hard water can clog your pores and lead to skin conditions, like acne, or make existing skin conditions worse, such as eczema and dermatitis. For your hair, hard water may cause itchiness and dryness on your scalp, as well as lead to color dullness. If you notice any of these things happening over time, it may help to get a shower filter. Shower filters are also great for people who simply don’t want to come in contact with any water contaminants, even though they aren’t drinking the water. To find out what contaminants are in your water, check out the Environmental Working Group’s Tap Water Database. From there, you can search for shower filters that remove the contaminants that are in your water.
What can I expect with installation?
Shower filters are pretty easy to install and can be done without a professional. For inline shower heads, all you have to do is unscrew your shower head from the arm (the pipe that is connected to the shower head), take off the plumber’s tape present, replace the plumber’s tape, then insert the filter, screw the shower head back on, and you’ve got filtered water. The same instructions apply to built-ins, with the only exception being that you need to remove your shower head to apply your new one.
