Did you know?

HASA Sani-Clor® has been the gold standard pool sanitization method for more than half a century. Sodium hypochlorite is made from naturally derived products. After it cleans your pool, it returns to salt—and is safe for the oceans, your family and the environment.

Because HASA Cares

HASA observes a Triple Bottom Line Philosophy in everything we do as a brand. This includes caring for our Planet, but also giving back to the many communities where we do business.

Whether it’s providing safe, clear drinking water to local neighborhoods after a flood or hurricane, raising funds for the “Water for a Warrior” project to provide hydro-therapy spas for our veterans, or helping schools and other organizations to enjoy the benefits of HASA quality, we’re proud to make a difference.

Please be responsible when managing household or pool/spa cleaning supplies.

Liquid bleach like many household chemicals is for external use only—and needs to be treated with respect and used properly. Please always refer to the instructions on the packaging and on the accompanying label before using.
