You turn on the shower, and there it is—that unmistakable chlorine smell, like you’re about to dive into a swimming pool instead of taking a relaxing shower. That chemical odor isn’t just unpleasant; it’s a sign that your tap water contains chlorine and other disinfectants that municipalities use to keep water safe during transport. But here’s the thing: while chlorine does its job killing bacteria in water pipes, it can leave your skin feeling dry and your hair brittle. The good news? Getting rid of that swimming pool smell is simpler than you might think, and the solution involves vitamin C.
Why Does Your Water Smell Like a Swimming Pool?
I used to wonder why my morning shower felt more like a trip to the local pool. Turns out, water treatment facilities add chlorine and chloramine to tap water as disinfectants. These chemicals are effective at keeping water safe as it travels through miles of pipes to your home, but they stick around even after reaching your faucet.
The concentration varies depending on where you live and the season—I noticed the smell got stronger during summer months when treatment plants increased disinfection levels. While these chemicals are generally considered safe at regulated levels, they can affect your skin’s natural moisture barrier and strip essential oils from your hair. That tight, dry feeling after showering? That’s chlorine doing its thing.

The Vitamin C Solution That Actually Works
After trying various methods—letting water sit out, using different soaps, even considering expensive whole-house systems—I discovered that vitamin C neutralizes chlorine on contact through a simple chemical reaction. It’s not just marketing hype; it’s actual chemistry that converts chlorine into harmless compounds.
The StoneStream Vitamin C Cartridge uses this principle in the most practical way possible. Instead of treating all your household water (which honestly seems wasteful for toilet flushing and laundry), it targets your shower water where that chemical smell matters most. The cartridge contains concentrated vitamin C in the form of ascorbic acid, blended with lemon oil and lavender oil for a refreshing scent that replaces that pool odor.
What impressed me was how immediately noticeable the difference was. That first shower after installation, the chlorine smell vanished completely. No chemical odor, just clean water with a subtle citrus hint. My skin felt softer almost right away—less of that tight, stripped feeling I’d gotten used to tolerating. The vitamin C works by neutralizing chlorine molecules before they ever touch your skin, rather than trying to repair damage after exposure.
How to Install and Use a Vitamin C Filter
I’m not particularly handy, so I was relieved when installation took maybe five minutes. The StoneStream cartridge simply screws into your existing shower setup between the pipe and your showerhead. No tools required, no plumber needed, no permanent modifications to your bathroom.
Here’s what you do: Unscrew your current showerhead (lefty-loosey), attach the vitamin C cartridge to the shower arm coming from your wall, then screw your showerhead onto the cartridge. That’s genuinely it. The whole process is straightforward enough that I’ve now installed them in both bathrooms without any issues.
Each cartridge lasts approximately 2-3 months depending on your water usage and chlorine levels. You’ll know it’s time to replace when that swimming pool smell starts creeping back. At just $17.90 (down from $32.90), replacing the cartridge regularly is far more affordable than dealing with dry skin treatments or specialty hair products to combat chlorine damage.
Beyond Removing the Smell: Additional Benefits
Getting rid of that chemical odor was my main goal, but the vitamin C cartridge delivered some unexpected bonuses. My skin stopped feeling so dry and itchy after showers—I actually cut back on how much body lotion I was going through. My hair felt smoother and looked shinier, probably because the vitamin C wasn’t stripping away natural oils like chlorine does.
The antioxidant properties of vitamin C may also help protect your skin from free radical damage. While I can’t make medical claims about what it treats, I noticed my skin just looked healthier overall. That tight, uncomfortable feeling I’d accepted as normal after showering? Gone completely.
The lemon oil and lavender oil in the cartridge create this refreshing, spa-like experience. Instead of dreading that chlorine smell first thing in the morning, my shower actually became something I looked forward to. The citrus scent is invigorating without being overwhelming—just enough to make you feel energized and fresh.
Alternative Methods (And Why They Fall Short)
Before discovering the vitamin C solution, I tried other approaches with mixed results. Letting water sit out for 24 hours does allow chlorine to evaporate, but that’s obviously impractical for showering. Carbon filters can reduce some chlorine, but they don’t neutralize it as completely as vitamin C does, and they often reduce water pressure noticeably.
Some people suggested using dechlorinating soaps or shampoos after showering, but that felt like closing the barn door after the horse escaped. Why expose your skin to chlorine and then try to fix the damage, when you could prevent the exposure in the first place? The vitamin C cartridge addresses the problem at the source, treating the water before it touches you.
Whole-house filtration systems work but cost hundreds or thousands of dollars, require professional installation, and filter water you don’t even need purified (like water for your lawn or toilet). For most people, that’s serious overkill when the issue is specifically shower water.
Final Thoughts: Clean Water Without the Chemical Smell
That swimming pool smell in your tap water doesn’t have to be something you just tolerate. The vitamin C solution—specifically through a dedicated shower cartridge like the StoneStream Vitamin C Cartridge—offers a practical, affordable way to neutralize chlorine and eliminate that chemical odor completely.
After using it for several months, I honestly can’t imagine going back to regular chlorinated shower water. The difference in how my skin and hair feel is too significant to ignore. Plus, at under $18 for a replacement cartridge that lasts months, it’s one of those small investments that genuinely improves your daily life.
If you’re tired of that chlorine smell and the dry, stripped feeling it leaves behind, a vitamin C cartridge is worth trying. StoneStream has been innovating shower technology since 2015 with over 500,000 satisfied customers globally, and their British-designed products reflect that experience.

Frequently Asked Questions
How does vitamin C remove the chlorine smell from water?
Vitamin C (ascorbic acid) neutralizes chlorine through a chemical reaction that converts chlorine molecules into harmless compounds on contact. Unlike filters that trap chemicals, vitamin C actually transforms chlorine at the molecular level, completely eliminating both the smell and the chemical itself before water touches your skin. This reaction is instantaneous and highly effective, which is why you’ll notice the swimming pool odor disappear immediately after installing a vitamin C cartridge.
How long does a vitamin C shower cartridge last?
A typical vitamin C shower cartridge lasts approximately 2-3 months with regular use, though this varies based on your household’s water usage and local chlorine levels. You’ll know it’s time to replace the cartridge when you start noticing that chlorine smell returning to your shower water. The StoneStream Vitamin C Cartridge at $17.90 makes replacement affordable, costing just a few dollars per month for chemical-free shower water.
Will a vitamin C filter reduce my water pressure?
No, vitamin C cartridges like the StoneStream model don’t reduce water pressure the way carbon filters often do. The vitamin C works through chemical neutralization rather than physical filtration, so water flows through freely without restriction. You get the full pressure and flow rate you’re used to, just without the chlorine and chemical smell. Installation doesn’t require any modifications that would affect pressure either.
Can I use a vitamin C cartridge with any showerhead?
Yes, vitamin C cartridges use standard threading that works with virtually all shower setups. The StoneStream Vitamin C Cartridge simply screws between your existing shower arm (the pipe from your wall) and your current showerhead, regardless of brand or style. No special adapters needed, no tools required. Whether you have a rain showerhead, handheld spray, or standard fixed head, the cartridge will fit your setup perfectly.
Is vitamin C in shower water safe for sensitive skin?
Vitamin C is actually gentler on sensitive skin than chlorinated water. While chlorine can dry out and irritate sensitive skin, vitamin C neutralizes those harsh chemicals before they touch you. The ascorbic acid itself is the same compound found in many skincare products and is well-tolerated by most people. The StoneStream cartridge also includes soothing lemon oil and lavender oil, creating a gentle shower experience that’s particularly beneficial if you have reactive or easily irritated skin.
