EPA Registered Disinfectant

Concentrated Tablet

When safety is your top priority, you need EfferSan. It's an EPA Registered Disinfectant and Sanitizer that tackles sanitizing 99.999% of bacteria in 1 minute. Now, that's a job well done. 

When added to water, EfferSan's active ingredient (Sodium Dichloro-S-Triazinetrione) creates a hypochlorous acid, a mild chlorine solution like that of a swimming pool. By using pre-measured, dry tablets, EfferSan's solution is milder and safer than many household cleaners. Best of all, Effersan is mixed in small batches, so each bottle contains a fresh solution that is formulated without additives, stabilizers, or fragrances.

Plus, EfferSan covers hard to tackle viruses including Canine parvovirus, Staphylococcus aureus, and many other enveloped viruses such as influenza and coronavirus.

Effersan's active ingredient is within the chlorine family, however Effersan is formulated as a pure sanitizing and disinfecting agent. Unlike liquid bleach and other conventional cleaning products, Effersan has no additives or stabilizers, which makes it safer for people, pets, and the environment.

Environmentally Friendly Concentrated Formula

When you buy conventional cleaning products, you're paying for a lot water. Concentrated cleaning products are more efficient to ship, reducing the amount of fossil fuels used to ship. Like Wysiwash, Effersan is environmentally safe and biodegradable.

We love Effersan. It's convenient and safe to use around our dogs. Effersan kills canine parvovirus and is simple to use once the tablet dissolves into a spray bottle of water and lasts a long time too. I highly recommend it if you have pets.
