Our Story
A small company with one honest promise.
Bio Safe Technologies was founded by Mark Heston in Osceola, Iowa, to bring a trusted odor-elimination formula to the homes, and pets, that need it.
Why we made Pet Litter Maxx
Most litter odor products don’t eliminate odor, they cover it with perfume. For homes with children, multiple pets, or anyone with chemical and fragrance sensitivities, that trade-off isn’t good enough.
Pet Litter Maxx takes a different approach: nano enhanced natural earth minerals that neutralize ammonia, H₂S, urine, and fecal odor at the molecular level, while helping prevent bacteria growth in the litter box. No fragrance. No harsh chemicals. No masking agents.
It works with the litter you already use, extends its life, and even helps attract cats back to the box, which makes it great for litter training kittens.
