## Questions & Answers

**Q: does it filter out fluoride?**
A: I have a fluoride hypersensitive adult son with autism who gets headaches within minutes of a fluoridated shower, and that's WITH a typical carbon shower filter.  This filter is the only one I have found that takes enough of the fluoride out for my son to be able to shower.  We have very soft water and the results will be different for those with hard water, but if you follow these protocols that I use, you will get the maximum fluoride and contaminant removal:  1) Shower 4 minutes or less, 2) Use warm, not hot, water to reduce absorption, 3) Keep water pressure as low as it will possibly go for maximum contact time with filtration materials, 4) Change filter every 3 months, not 6 as the manufacturer recommends.  Of course, these recommendations are for my massively fluoride-reactive son, the most vulnerable of those "miner's canaries".  Most people will simply enjoy this filter for the full 6 months, and without all the fuss that we have to do, and will be pleased that it is much more effective than other shower filters.

**Q: Is this good for hard water and not simply chlorine?**
A: A shower head filter cannot soften water (remove hard water minerals). It's easy to confirm this by using a hard water test kit. The only way to get soft water in a shower is to install either a whole house water softener or the "ShowerStick" shower water softener made by WaterSticks (watersticks.com). You won't get the results you're looking for unless you remove the hard water minerals.

**Q: Does the filter affect the water pressure?**
A: No, not at first, but as the filter fills with things it filters the pressure decreases. You will need to change it out routinely depending on your water.

**Q: Can I use my own handheld showerhead in place of the one that comes with it?**
A: I believe its the shower head that attaches to the filter has a smaller connection than your hand held.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great choline filter. Changed my life.
*by T***S on September 11, 2025*

I have asthma which is chlorine triggered. This filters chlorine so I can shower without the steam triggering my asthma. Amazing side benefits are my hair coloring stays bright, my hair is shiny and I don’t itch. The choline was doing more than I realized. Life changer. Highly recommend!

### ⭐⭐⭐⭐⭐ A Shower Upgrade – Skin and Hair Feel Amazing!
*by Q***S on April 6, 2025*

I’m really impressed with the Aquasana Filtered Shower Head! The flow rate gives me great water pressure, and the up flow design makes sure the water flows smoothly without clogging. (I did have to put plumbers tape on where you attach it, as it leaks a tiny bit, but overall I really enjoy this and think it was a good purchase).What really stands out for me is how it’s helped with the itching I used to feel after showering with regular water. The carbon and copper-zinc says it filters out over 90% of chlorine, and I’ve noticed a big difference in my skin, and it’s much less dry and irritated. That's a huge win for me!!Showering with it is honestly a pleasure. My skin feels softer, and my hair doesn't feel like it has buildup on it anymore.The filter lasts up to 6 months or 10,000 gallons they say, and replacing it is super easy. Installation was easy, and it only took about 10 minutes minutes to set up. (that includes adding the extra plumbers tape too).Overall, I’m really happy with this. I've used it every day for 3 months, and it works good for me. If you’re looking for something to improve your skin and hair, this is definitely worth trying!

### ⭐⭐⭐⭐ High quality shower filter
*by H***. on March 19, 2025*

Easy to install and works well so far with good water pressure. Though I have two issues to give it only 4 stars:1. At this price point, I'd have expected the box to include a little bit of teflon tape to seal threads, instructions recommend it but it's not provided, and it should be as it's marketed as DIY, and not everyone might have it handy. Previous shower filter I bought provided this in the past. Another thing to point out it, Amazon description suggests hand tightening only, but I find that's hard in most cases and not enough, it's better to tighten a little more using pliers to avoid leaks. User manual actually recommends using pliers and it contradicts with the description on Amazon.2. Another thing I noticed looking at the user manual. Max operating temperature is listed as 115F, where as most showers in US max out at 120F. I feel like this could be setting grounds to dismiss any future warranty claims as user error due to usage outside of operating temperature, but that's just me and I guess we'll see how long it actually lasts. Maybe don't mention you let it run hot water ever, if making a warranty claim.
