Turn Your Shower Into a Daily Wellness Ritual
SENTRY SHOWER FILTER
Every morning, you step into the shower expecting to feel clean and refreshed. But if your water is filled with chlorine and other hidden contaminants, you’re not just rinsing off…you’re drying out your skin and coating your hair in chemicals.
The Sentry Shower Filter transforms that experience.
It removes chlorine, heavy metals, and impurities that irritate your skin and dull your hair. Then, it delivers oxygen-rich, mineral-balanced water that feels softer, cleaner, and more natural. The way water was meant to be.
You’ll notice the difference in just a few days.
✅ Softer hair.
✅ Smoother skin.
✅ Less skin irritation.
✅ Healthier-looking shine.
It installs in minutes (no tools, no plumber) and lasts for months before you need a filter replacement.
It’s a small change that makes a big difference in how you feel every single day.

SENTRY SHOWER FILTER
Safe, I mean to know my water is coming out clean for our skin. It has helped our skin especially my husband's back no break outs looked smooth.
I am completely 100% happy with my 2 filter under sink filter system. So tired of lugging 5 gallon plastic jugs to and from the store, with water that comes from who knows where. I poured out my dogs bowl of city water and filled her bowl up with my new Sentry H2O water, she immediately knew the difference and drank half the bowl. Just a great product.
Thanks so much!!!
I am a first time customer out in San Diego CA, and I recently purchased the SENTRY SHOWER WATER FILTER. This SENTRY water filter is extremely high quality and does not reduce the water pressure in my shower. It also removes a percentage of the total dissolved solids according to my TDS test Meter. I also Noticed that my hair is squeaky clean after taking showers! I can also use the SENTRY Filtered water for watering Indoor and outdoor plants, and for soaking my feet in Epsom Salt baths. One of the best health investments that I have ever made. With the proper adapters you may be able to use this filter in an RV application as well? I give THE SENTRY SHOWER WATER FILTER product a Super 5 platinum Stellar Stars for overall Price, quality and performance! First time buyer, and a NEW LIFE TIME CUSTOMER!
I recently moved from an area that had city water to an area that had well water. While I was excited to not have to pay a water bill any more, that excitement turned to total sadness as my soft and subtle brown skin turned to a scale-y, extremely dry, painful, and gray hued tone because of hard water. I decreased showering daily because the water would hurt my skin and showering was painful. I even bought showered heads with a filter from Amazon. A plumber let us know that we had hard water at a level between 6-9 and we could not get a a whole house water filter with salt because our septic would not allow it. Any hoo, I happened to see that someone I followed on Youtube promote the company and I thought, what's the worse that could happen, I already have snakeskin. The first shower with the new Sentry 2.0 shower filter attachment was absolutely pain free. After 3 weeks of usage, my skin is back to being beautiful brown and the snake skin is 75% cleared up. I AM SO THANKFUL AND GRATEFUL to you all. I am saving up to be able to afford the whole house system in 2027. You guys are heaven sent and I hope this helps others in their tortuous journey of hard water and eczema like symptoms--that there is light at the end of the tunnel. Thank you, thank you, thank you!
Warmest regards,
