FreeBact® Dosage includes systems for continuous dosing in buildings, pools, spas, and other water systems. The results below are based on sampling and analyses from real-world installations, with a focus on microbiological water quality.

Property Management Company, Norrland
Follow-up sampling in the building's water system showed a clear reduction in bacterial levels. Hot and cold water samples measured 10 cfu/1000 ml, while a sample taken after stagnation showed 150 cfu/1000 ml. Compared to previous levels, the results corresponded to a reduction of approximately 90–98.8%. [Source: test results, 2026 sv | eng]

A municipal inspection confirms that the facility uses FreeBact® Dosage. An accredited pool sample showed fewer than 1 cfu/ml culturable bacteria and fewer than 1 cfu/100 ml Pseudomonas aeruginosa. The levels were below the applicable guidelines. [Sources: Berg och Härjedalen Environmental and Building Committee and Hjortens Laboratorium, 2026]

FreeBact® Fogging is a portable solution for rapid and comprehensive disinfection of enclosed spaces using dry fog. The system with Hydra LiTE and Hydra AiO has been tested by the independent laboratory Melbec Microbiology in accordance with BS EN 17272:2020, the standard for automated processes for airborne room disinfection.

Room disinfection tested according to EN 17272
FreeBact® Fogging was tested together with Hydra LiTE and Hydra AiO in an enclosed space of 36 m³. The test was carried out by the independent laboratory Melbec Microbiology in accordance with BS EN 17272:2020. Under controlled test conditions, the system achieved a reduction of at least 5 log for bacteria and at least 4 log for yeast. The system thus met the requirements applied in the test. The test cycle included 22 minutes of treatment and 15 minutes of ventilation. [Source: BS EN 17272:2020, Melbec Microbiology, United Kingdom, 2025]
