Everyday Guide to Pet Hydration - Vet-Informed Digital Guide

Torus filters are replaceable filters that can be inserted into your Torus. You can easily twist a Standard or Advanced Filter into any of our Torus water dispensers. Each individual filter lasts 30 days, and they are sold in packs of six. You can subscribe to replacement filters to make sure your pet doesn’t go a day without clean water.

Standard filters use activated carbon. Advanced filters have a perforated wall made from stainless steel for a more controlled release. They also contain FDA approved and NSF certified antimicrobial features that reduce bacteria and remove impurities.

Torus Pet’s activated carbon filters contain small pieces of carbon that are very porous. With millions of tiny holes in each grain, just a few grams of activated carbon can cover the surface area of a sports field! This huge surface area enables activated carbon in both our Standard and Advanced filters to absorb contaminants and effectively remove them from water, so only clean water flows into the drinking well of the Torus.

Activated carbon is most effective at absorbing contaminants when there’s a slow water flow with low pressure and cold water. That’s why water passes slowly through the Torus and into the drinking well in lower volumes—enough for your pet to drink instead of gulp in one go.

Activated carbon can effectively remove hundreds of contaminants found in tap water. Studies conducted by the Environmental Protection Agency in the United States (EPA) and NSF show that activated carbon is the only filter technology able to remove the following chemicals:

• All 32 identified organic contaminants including THMs (chlorine by-products) 
• All 14 listed pesticides (e.g., glyphosate), including nitrates
• 12 most common herbicides

Activated carbon is powerful and can remove over seventy contaminants from water without stripping water from healthy minerals like magnesium. It doesn’t remove dissolved metals like iron, which isn’t considered a contaminant.

Some microbiological contaminants like coliform, viruses, and small bacteria are more difficult to remove. Inorganic contaminants like arsenic, asbestos, and radionuclides are only partially removed.

To replace a filter, run it under running water for about 10 seconds to remove any active carbon. Align the arrow of the cap to the tap icon, then insert or replace the old filter with a new one. Don’t forget to put the cap back on at the end. Check out our guides and videos for more information.

Each filter lasts 30 days.

Filters are 100% recyclable and should be recycled. Both the PET material and carbon are eco-friendly.
