Customer Reviews
Good value for a system
I was looking for a water filter that wouldn't break the bank, and the Under-Sink Tap Water Filter System from Sentry H2O seemed like a solid option. I got it during a seasonal sale, which helped a lot with the price. The free shipping on systems was also a nice perk. I felt like I got good value for what I paid, and it's definitely an improvement over just drinking tap water. Overall, a practical purchase.
Quick shipping, good water
Ordered replacement filter cartridges. They shipped quickly. Received them in 3 days. Water quality is consistent after changing. No issues.
Good system, minor hiccup
I purchased the Whole House Water Filtration System. The system itself is robust and seems to do a great job filtering our water; the difference in taste and even feel when showering is clear. Delivery was prompt, arriving in about a week. My one small gripe is that the instructions for the initial flush weren't as detailed as I would have liked, and I had to look up a video online to be sure I was doing it right. Customer service was responsive when I had a question about filter replacement frequency. Overall, a solid product, but clearer installation guidance would make it even better.
Water tastes way better
Got an Alkaline Water Filter last month 'cause my tap water just wasn't cutting it. It arrived pretty fast, and my husband put it in without too much fuss. Honestly, the water tastes so much better now. No weird aftertaste or anything. It just feels good to drink, like it's actually refreshing. Pretty happy with it.
Reliable filter, second time
This was my second time buying an Under-Sink Tap Water Filter System from Sentry H2O, this one for my vacation home. My first system, bought two years ago, is still working great, only needing filter changes. I came back because the quality is consistent. The installation was just as easy this time around, and the water tastes clean and fresh, just like at my main house. It's good to know I can count on them for a reliable product.
Smooth order and delivery
I ordered the Wellness Water System a few weeks ago. The website was easy to navigate, and the ordering process itself was straightforward. I received a confirmation email right away. It took 5 days to reach Denver after shipping, which was within the expected timeframe. Installation was pretty simple; I managed to set it up myself following the instructions. The water quality is noticeably better, with a cleaner taste. I also bought a pH Test Kit, and the results show the water is indeed alkaline. Customer support wasn't needed, so I can't speak to that, but the whole experience from start to finish was efficient.

can you use more than one coupon code at a time? like a military discount and a new customer one?
Is Sentry H2O better than Berkey? Trying to decide between them for a countertop system.
Hey, anyone know if these guys ever have sales? Waiting to pull the trigger on a whole house system but hoping for a deal.
Thinking of getting the under-sink system. How hard is it to install? I'm not super handy.
Does Sentry H2O actually remove fluoride? Some filters say they do but then it's barely anything.
