Classic Replacement Tap Water Tank

$34.95

Replacement tap water tank for AquaTru Classic countertop purifier models. Does not fit AquaTru Carafe purifiers. With regular maintenance, you should not have to replace your tap water tank. However, if product care is not maintained, a replacement may be needed. AquaTru’s patented technology works by recirculating water in the tap tank, resulting in highly concentrated (very high TDS) waste water remaining in the tap tank after each full cycle. To extend the life of your purifier parts and prevent serious damage to your AquaTru machine, ALWAYS empty your waste water after each cycle. Remember to wash your tanks weekly and complete descaling maintenance, as needed, to avoid excessive mineral build-up in the tap tank and internal system.

Independently Certified to NSF Standards

Reduces 84 Contaminants

How AquaTru Purifiers Work

Every AquaTru filter has one job, and they work together to get your water fully purified.

  • Pre/Carbon Filter: Captures sediment and rust, then reduces chlorine and chloramine for cleaner-tasting water. Replaced every 6-months.
  • Reverse Osmosis Filter: Reduces lead, arsenic, chromium-6, and other heavy metals. Replaced every 1-year.
  • VOC Carbon Filter: Reduces VOCs and "forever chemicals" like PFOA and PFOS. Replaced every 2-years.

"One of the most popular pitcher filters that everybody thinks of is only certified to remove 8 contaminants. AquaTru is certified to remove 84. There’s really no comparison."

Reviews

I am very impressed with

"I am very impressed with the quality of the classic model and service provided by AquaTru A note on the product already says that scaling is possible in the tapwater tank I experienced some scaling in the tapwater tank after using it for about 10 months and as soon as I reported this to AquaTru they immediately sent me replacement set of tanks and a chemical and several packets to clean the scale in the old tank I have now been able to clean the old tank with the help of the chemical and have also a new set of tanks The Precision with which the tanks are made and machined is most impressive. The new tanks fit in perfectly in place of the old tanks without an issue or leakage. The quality of filtered water is excellent"
