Tight, itchy skin the minute you step out. Hair that feels like straw. A bathroom that smells faintly like a pool. So, do shower filters work, or is it all marketing? The answer comes down to one thing in your water.
Yes. A good shower filter targets chlorine, the main thing drying out your family's skin and hair in the shower. The Tubo Go Shower Filter removes up to 99% of chlorine, plus fluoride, heavy metals and up to 99.9% of bacteria and viruses. It's clinically tested and screws on behind your existing showerhead in minutes. Want a whole new head instead? The Tubo Pro Showerhead Filter does the same job, built in.
What does a shower filter actually remove?
Chlorine, first and foremost. Your city adds chlorine (or its cousin, chloramine) to kill germs on the way to your tap, at up to 4 mg/L under US rules. Great for drinking. Rough on skin and hair in a hot shower.
A shower filter is a cartridge packed with media that grabs or neutralizes chlorine as water rushes through. These four show up on almost every box:
KDF-55
Copper-zinc granules. They turn chlorine into harmless chloride, and work even better in hot water.
Calcium sulfite
A mineral that reacts with chlorine. Made into ceramic beads so hot water doesn't wash it away too fast.
Vitamin C
Neutralizes chlorine and chloramine on contact. One of the fastest media there is.
Activated carbon
The star of drinking-water filters. Loves slow, cold water. A shower gives it neither.
The best filters stack several of these. Each one covers a weak spot in the others. That's why Tubo filters don't rely on a single media type.
What unfiltered shower water costs your skin
Warm water and long showers mean skin takes in more of what's in the water. Chlorine strips away the oils that keep it soft. Do that every single day and it adds up.
You towel off and your skin already feels tight. By bedtime your shins are flaky. Your little one is scratching at night again, and you're reaching for the lotion for the third time today.
Your hair pays too: frizz, dull color, ends that snap. Many families never connect it to the water. Then they go on vacation and everyone's skin calms down.
What makes a shower filter work in hot water?
A pitcher filter gets cold water dripping through slowly. A shower filter gets hot water blasting through at full pressure. Here's what that means:
This is where heat-friendly media shines. KDF and calcium sulfite react fast in hot water, where carbon struggles. So look for a multi-media design built for a hot shower, not a carbon-only cartridge. That's exactly how Tubo filters are built.
Chlorine or chloramine? How to check
Some cities use chloramine, chlorine bonded to ammonia, because it lasts longer in the pipes. The CDC notes chlorine can evaporate from standing water, but chloramine won't.
To check your shower water, use test strips that read total chlorine. They pick up chlorine and chloramine. Not sure what your city uses? Our guide to chlorine vs chloramine shows you how to find out in two minutes.

What should a good shower filter tell you?
A good filter makes it easy to know what you're buying. Look for one that:
- Names what it removes, and how much. "Removes up to 99% of chlorine" beats "cleaner water."
- Uses media built for hot water. Multiple stages, not carbon alone.
- Tells you when to replace it. A clear schedule, so you never run a spent cartridge.
- Has real reviews from real families. Not just a slick box.
Tubo checks every box. Up to 99% of chlorine out, plus fluoride, heavy metals and up to 99.9% of bacteria and viruses. Clinically tested. A fresh cartridge every 3 months. The Tubo Go is rated 4.9 stars. Our best shower filters for sensitive skin guide shows how each filter type stacks up.

How to test your shower filter at home
You don't need a lab. Grab chlorine test strips that read total chlorine (pool and aquarium stores sell them). Total chlorine catches chloramine too.
“It helps our skin so much. We don't come out feeling dry anymore.”
So, do shower filters work for your family?
If chlorine is in your water, yes. Signs it's hitting your family: skin feels tight or itchy right after a shower, the bathroom smells like a pool, or everyone's skin is fine on vacation and flares at home.
Test strips will show you how much chlorine you're starting with. The Tubo Go or the Tubo Pro Showerhead takes it out. Torn between them? Read showerhead filter vs inline shower filter.

Frequently asked questions
Do shower filters really make a difference?
Yes. The Tubo Go Shower Filter removes up to 99% of chlorine, plus fluoride, heavy metals and up to 99.9% of bacteria and viruses. Skin stops feeling tight after you towel off.
Can a shower filter help with eczema?
Chlorine strips the oils that protect skin. Taking it out of the shower means less dryness and less itch after every wash, which is why so many eczema families filter their water.
How do I check my water for chloramine?
Use test strips that read total chlorine. They pick up both chlorine and chloramine, so you can see what's in your shower water.
How fast does the Tubo Go Shower Filter work?
From the first shower. It screws on between your shower arm and showerhead in minutes with no tools, and doesn't affect your water flow. Swap in a fresh cartridge every 3 months.
How do I know if my shower filter is still working?
Compare a cup of hot sink water with a cup from your filtered shower using total-chlorine test strips. The shower cup should read clearly lower. Either way, swap in a fresh cartridge every 3 months to keep it at full strength.
