Introducing barebird™ — Smells like nothing. On purpose.

Finally, an odor control solution that actually works without relying on fragrances

barebird™ is BioLargo’s new company-owned line of fragrance-free odor eliminators, powered by our patented CupriDyne® technology. That’s the same chemistry behind Pooph’s success, first proven over 10+ years in landfills, livestock barns and wastewater plants. Most consumer products mask odors with fragrance, but barebird breaks down the molecules that cause them on contact, which appeals to a growing fragrance-sensitive market. The line launches with a Pet Odor Eliminator and a Laundry Odor Eliminator, and for the first time BioLargo owns the brand, the customer relationships and the value it builds. Visit barebird.com, and stay tuned as we launch the marketing campaign to build barebird into the next great CupriDyne brand.
