"I enjoy my Classic AquaTru water filter. I originally ordered the mineralized filter, but after 6 months, I realized I'm getting too much electrolytes. I do drink a lot of water. However, I also found out I can switch the mineralized filter with the Classis Pre/Carbon filter, making the water at a PH level of 7. Now I can enjoy all the water I want without worrying about getting too many electrolytes. Thank you, AquaTru."
"Love everything about my aqua tru water system and the ease of using the filters. The water that is dispersed is great tasting ,and so comforting knowing the harmful things are filtered out"
"Very powerful product that really works. My water now tastes amazing. Best purchase ever."
"I can say nothing but positive things concerning my recent purchase with Aquatru. The delivery company said they delivered my order and I said they didn’t. Aquatru immediately sent out a replacement delivery, no questions asked. Thank you. I love my Aquatru."
"This filter has been a great part of the AquaTru system. I like that it adds minerals back into the water, because the taste feels smoother and more natural compared to plain filtered water. The water comes out clean, fresh, and easy to drink. It also gives me more confidence knowing it’s helping with VOC reduction while improving the taste at the same time. Installation was simple, and it fit right into the system without any trouble. Overall, it’s a good-quality filter and definitely worth replacing on schedule."
"Love my AwuaTru!"
"Fabulous RO product and this filter insures I loose no minerals. Highly recommend and am very satisfied."
"works well, but I would like the water to be a bit more salty. still have to buy bottled alkaline water in the summer heat. But this level of saltiness works well for cooking"
"Great product. Like how easy it is to install ."
"I love it. I’m drinking so much water now. I can tell the big difference with my health and well-being. Easy to install."
