This package contains all the filters you need for up to two years after purchasing your AquaTru. The package contains 4 pre-carbon filters (1-2), 2 VOC carbon filters (4) and one reverse osmosis filter (3) and is suitable for AquaTru Under Sink. The pre-carbon filter should be replaced every six months. It removes bacteria, sediment and other large particles. The activated carbon also removes any chlorine taste from the water. The reverse osmosis filter (3) is designed to filter even the smallest harmful substances from the tap water. This filter only needs to be replaced once every two years. The VOC carbon filter filters the last impurities from the water, optimizes the taste of the water and makes your water ready for consumption. With this package, you have enough supplies to last for a total of 2 years.

Time for replacement?
The AquaTru Under Sink system contains three filters that must be replaced at regular intervals to maintain performance. 

• (1-2) Pre-Carbon Filter: replace after 6 months
• (3) Reverse Osmosis Filter: replace after 2 years

Helpful Hint: Write the date of filter installation with a permanent marker on the filter body, or use our helpful Filter Replacement Records chart, so you can easily identify when to replace the filters.
