  • Our take on the Aquasana Shower Filter

    The Aquasana Shower Filter is a two-stage coconut shell carbon filter that screws onto a standard 1/2-inch shower arm and reduces chlorine in your shower water. It is certified to NSF/ANSI 177 for chlorine reduction and NSF/ANSI 61 for materials safety, and it handles a 2.5 GPM flow rate. The filter is rated for about 10,000 gallons, or roughly six months of typical use, and takes Aquasana replacement cartridges. It suits renters and homeowners who want chlorine reduction without a whole-house system, though it does not soften water and adds a bulky housing behind the shower head.

    What reviewers say

    Owners generally report less chlorine smell and less dry, itchy skin after switching, and many say water pressure holds up. Complaints center on the bulky housing, the need for frequent cartridge changes, and the fact that it does not fix hard water.

    What people mention
    • Chlorine reductionPraisedUsers say the chlorine smell in the shower drops noticeably after installing it.
    • Skin and hairPraisedSeveral owners report less dryness and itching after switching from unfiltered water.
    • Water pressureMixedMany say flow stays strong, but some notice a slight drop compared with no filter.
    • Size and bulkCriticisedThe housing is large and pushes the shower head out and down.
    • Cartridge lifeCriticisedOwners say the cartridge needs replacing about every six months, which adds ongoing cost.
    • Hard waterCriticisedIt filters chlorine but does not soften water, so mineral scale and hardness remain.

    About the Aquasana Shower Filter

    The Aquasana Shower Filter is a shower head filter that reduces chlorine in shower water. It uses a 2-stage filtration system with coconut shell carbon. It is a filtration system only, not a reverse osmosis system or a water softener.

    The filter connects to a standard ½" shower arm and includes a handheld shower head. It treats up to 10,000 gallons (38,000 liters) of water and has a 6-month filter life. The filter should be replaced every six months with an Aquasana replacement shower filter.

    Questions and answers

    Does it soften hard water?
    No. It is a carbon filter for chlorine and similar contaminants, not a water softener, so calcium and magnesium stay in the water.
    How often do I replace the filter?
    Aquasana rates the cartridge for about 10,000 gallons, or roughly six months of typical use. Heavy use shortens that.
    Will it fit my shower?
    It connects to a standard 1/2-inch shower arm and fits shower heads up to 4.5 inches in diameter. It is built around the AQ-4100.
    Does it reduce water pressure?
    The rated flow is 2.5 GPM, so most users keep normal pressure. Some notice a small drop, especially with low-pressure plumbing.
    What is in the box?
    The filter unit and a handheld shower head. Replacement cartridges are sold separately.
    Is it certified?
    Yes. It is certified to NSF/ANSI 177 for chlorine reduction and NSF/ANSI 61 for materials safety.
    Where is the Aquasana Shower Filter cheapest?
    At eBay, for $25.00, 74% under what the other stores charge, as of our latest check.
    Where can I buy the Aquasana Shower Filter?
