How do I know when to change my AquaTru Classic countertop filter?
When it is time to replace a filter, a numbered light corresponding to the number of the filter that needs to be replaced will stay illuminated on the digital display panel. It will not turn off during filtering or after filtering. It will turn off only when you replace the filter(s) and press the filter reset button. See resetting filters.
Why is one (or more) of my filter lights illuminated continuously?
The filter number corresponding to the numbered light indicates that the filter needs to be replaced.

How do I reset my change filter indicator light(s)?
I just replaced a filter. Do I need to run any water through before drinking the water?
Run two full tank cycles after filter replacements. New filters take time to become saturated and properly filter the water when first installed. The first cycle may take longer than the normal 10-15 filtering time for 1 gallon of water.
You may notice bubbles or even cloudiness in the tap water tank. This is simply trapped air from the filters escaping and may be experienced during each use.
You may also notice some black cloudiness in your tap water tank within the first two tanks being filtered. Loose carbon dust from your new Pre-Filter or VOC Filter can release into the water as the filter fully saturates.
How many tanks do I need to run through AquaTru before using a newly installed pH + Mineral Boost Alkaline VOC filter?
After installing the pH + Mineral Boost Alkaline VOC filter, it is recommended to flush your AquaTru purifier with at least 4 tanks of water before consumption.
