Product review (4 stars): Works well to keep humidifier output smelling fresh
Product works as described. For reasons unknown in my area it is hard to find humidifier bacteriostat so online ordering is the best option.

Works well to reduce the potential 'stale/moldy' smell that can occur from continuous uninterrupted use of a large humidifier system.

Apply after filling containers or water reservoir as it WILL foam up like crazy from just small amounts.
