"Incredible grateful that I found aquatru you have wonderful products and a great service. It’s a huge difference in taste of my water compared with other brand out there. This is cleaner, purest for a healthier life. Thank you."
"So glad to have such an excellent filter. We're pleased to know that toxins are being efficiently removed from our water."
"This was RENEWAL of FILTERS . AQUA Tru is not new to me. I continue to be very satisfied with these Osmosis Filters. My call to the Customer Service for advice was fulfilled with knowledge and humor. Thank you."
"As a full time RV'er, I work in West Texas. It's the oilfield and as most know, poisonous chemicals are shot into the ground as part of the oil extraction process and so these effect the groundwater quality. As such, I ONLY drank bottled water, Aquafina to be exact. I needed a better system because I did not feel good about all of the plastic I was adding to the landfills with all of those Aquafina bottles. So I conducted lengthy research into water filter systems and reverse osmosis systems. I wanted the best system, one that filtered the most bad stuff out of the ground water. I know I got the best system with AquaTru. I even conducted my own blind taste test of AquaTru vs. Aquafina and AquaTru won, 5 times out of 5! No, it's not cheap, and I bought extra filters to last at least a year, but it is an investment into my health and the health of my pet too. Highly recommend."
"We love our Aqua Tru. The water is consistently delicious and we use it every day. It still surprises me how many people have never heard of it! ADVERTISE!"
"Love the water filter. Have been using it for many years."
"Crisp and delicious water. You can absolutely taste the difference between aquatru water and tap water . Plus I made a mistake when ordering my replacement filters and the customer service representative was kind and professional even when I was sure the mistake was aquatru’s not mine."
"Great filter - water tastes great! I've been using aquatru for the past 4 years and live in area where the tap water is not good for drinking. Aquatru's filters made me feel safe! Great customer service as well!"
"Initially 5 stars. But now 4 because I’m seeing that after some time, the plastic is discoloring and the spigot is hard to clean."
"This reverse osmosis filter is the main reason I like the AquaTru system. It gives me peace of mind knowing the water is being filtered more deeply than a basic pitcher or fridge filter. The water tastes very clean, with no strange aftertaste. I also like that the filter lasts a good amount of time, so it doesn’t feel like I’m constantly replacing it. Changing it was easy, and everything worked normally right away after replacing it. Overall, this is an important filter and one I’m happy to keep using."
