A 1962 chemistry kit, still on the shelf.

AirBoss began as a moisture-control product for hunting cabins outside St. Louis: closed up nine months a year, opened in October to a smell that didn't belong. The first units used the same calcium chloride formulation we still use today.

By 1968 we were shipping refills, which is when the brand became something we were proud of. Anyone can sell a thing once. AirBoss is built for the second purchase, and the third, and the twentieth.

We're a Willert Home Products brand. Family-owned, third generation, still in St. Louis.
