The AquaTru Stage 3 Reverse Osmosis filter is a proprietary replacement component designed specifically for the brand's Classic, Classic Smart, and Under Sink purification models.
This unit functions as the third stage of filtration, utilizing a membrane that filters down to 1/10,000 of a micron.
Because this specific component is integral to the system's ability to remove complex contaminants, it is the most technically critical replacement part for owners.
The filter comes as a single pack and weighs 0.39 kg, which makes it a compact, manageable component for routine maintenance intervals.
