The ROCB Filter is the second stage of the UltraLux Undercounter Water Machine’s advanced filtration system. 

It uses a reverse osmosis membrane and post-activated carbon block to provide up to 2 years of powerful filtration, delivering safe, clean drinking water free from harmful contaminants.

Filter Components

The ROCB Filter is a 0.0001-micron filter that combines reverse osmosis technology with a post-activated carbon block to capture contaminants and improve water quality.

Filtering Capabilities

The ROCB Filter removes a wide range of contaminants, including:

• Bacteria (e.g., E. coli, Salmonella, Campylobacter)
• Protozoa (e.g., Cryptosporidium, Giardia)
• Viruses (e.g., Hepatitis A, Rotavirus, Norovirus)
• Chlorine, fluoride, and heavy metals (e.g., lead, mercury, arsenic)
• Total dissolved solids (TDS) and inorganic salts
• Nutrients like nitrate, potassium, and magnesium
• Sulfates, bicarbonates, and chlorides

Long Filter Life & Notifications

The ROCB Filter provides clean water for up to 2 years or 1,000 gallons, depending on usage. The UltraLux Water Machine tracks filter performance and notifies you when it’s time for a replacement, ensuring you always have access to fresh water.

Simple Replacement Process

Replacing the ROCB Filter is quick and easy. Just follow these steps:

1. Position the machine where you can access the filters on the top.
2. Twist the ROCB Filter until it pops up. (Apply force to ensure it’s secure.)
3. Lift the filter out carefully—it may contain water that could drain slightly.
4. Lower the new filter into the cavity and screw it in securely.
