I use this with their glass pitcher, which I love. It's a convenient way to get good quality water without wasting all that plastic from buying plastic bottles of water.

Drop in easy. Seems to make water filtration process last longer.

As I drink the water from my pitcher I'm not only aware of the health benefits, bit the taste is so different from tap o red bottled water. It tastes full! ... Rich and alive. It's the water I always drink at home!

I absolutely love the way the water tastes and smells. I've studied water in re to nutrition, as well as diet in relation to healing. So, I'm not a certified expert but I have studied both sides of things extensively, which is more than I can say for most experts. I would first like to address the many reviews stating they couldn't get the pH over 8.5 or that they used a test strip. There is absolutely no reason to get water above a 8.0 rating; anything over that means it will taste bitter and could cause skin problems. While avoiding acidic water is important for health, the fastest way to alkalize your body is actually by eating lots of raw whole fruits and vegetables and avoiding animal products. You can also raise your pH by squeezing lemon into your water (which raises your pH but not the water's pH). But that aside, water really should not be above 8.0; 7 is ideal. Secondly, test strips are not meant to measure the pH of water. Even those that say they can be used for water are only meant to be a guide and does not make the user an instant expert. If you want to test the pH of water with a strip, drink only water from one source for 24 hours (no eating or drinking except the water) and measure your urine on the strip every few hours. If it progressively shows more alkaline in the final 12 hours, you've got your answer. Any time you're measuring pH, if your urine consistently 8 or above you may have a serious health condition, such as acidosis, and should see a medical professional; high pH in the urine could be a sign that your body is depleting your internal sources, such as bone, to balance the pH, which your body constantly strives to be between 6.5 & 7. In the a.m. it will be the most acidic and not a true indication of your body's health or the health of the water. So, don't test the first morning urine unless you want to raise your stress levels. Simple research will confirm what I've said here.
So, back to my personal review of the product: My first choice is distilled because it removes every contaminate -- it's the re-creation of natural purification (before the atmosphere was toxic in some parts of the world). However, I currently travel a lot and it's inconvenient to keep buying gallons, or refill jugs at a machine (Reverse Osmosis was 2nd choice). So, having a lot of bug out gear, I began to wonder if just using my Sawyer water straw and filling gallons in my hotel room from tap would be acceptable. However, that is more for survival sources to remove bacteria and microbes, and doesn't diminish fluoride or do anything to raise the pH. So, I began to research and found pH On The Go. After researching how the filtration takes place I was interested to try it. Since I'm starting with tap water & there's no need to worry about killing microbes, I felt this would be the next best thing to Distilled and maybe even a step above in some aspects because of raising the pH and bringing the water closer to a structured or original form.
I received these almost a week ago and haven't purchased a bottle of water since. I absolutely love the way the water tastes and smells and I can feel the pH level in my mouth, although I haven't actually used a gauge (but for me it's not necessary). I'm thrilled at how convenient and successful these little pouches are. It doesn't just taste better, it feels really good in my mouth. I process the water in one container, pour it into a 2nd 27 oz container and then refill the one with the pouch. I don't time it since it works quickly -- for me, about 15 minutes gets most the chlorine smell out, 20 min is golden, depending on how chlorinated your water source is. But I did try this is a 2 gallon decanter and with the little pouch it took more than 8 hours to get the smell out. I can only assume it has to do with the lack of circulation in that large amount of water. The little pouches are definitely best for smaller containers If I'm hiking, I just take the one container with the pouch and refill it as necessary (from drinking fountains or so forth). I haven't removed it from the container so far, just keep it in there with at least a little water to cover the pouch. I literally want to buy a set for everyone I know. For one thing, most people buy "purified" water and that is just tap water filtered through a charcoal filter to get the smell out, usually. You may as well drink tap and plug your nose. "Spring" water is not much better and the FDA only requires a small portion of the water to actually come from a spring, by that definition. I think this is an amazing product. I'm guessing that with regular use, I'll be able to tell when it's time to get a new pouch. But for now I'm keeping a rough estimate of how many gallons I'm using.
I hope this information has been helpful to someone. Cheers.

I love this product. When I am traveling and use the airport water station this is for sure to clean my water and it actually makes water taste better. I highly recommend this product.
