VOCs (Volatile Organic Compounds) are gases that can be released into the air, especially when heated. Some VOCs are harmful and linked to health issues. We carefully select and test all materials, including wood and adhesives, to ensure near-zero VOC emissions. While no sauna can be 100% VOC-free, our levels are extremely low—safe enough to be considered VOC-free for everyday use.

To ensure our saunas meet international quarantine and transport requirements, we must use methyl bromide for fumigation. However, instead of relying solely on gas, we also apply heat treatment, which allows us to reduce the amount of methyl bromide used. After treatment, International safety guidelines recommend 4 hours of ventilation to remove traces of methyl bromide. At Forge, we go far beyond that, using large industrial fans to air out the wood for 24 hours. This extended process ensures maximum safety and gives us confidence that all traces of gas have been removed. Methyl bromide is a volatile gas that dissipates quickly. After our extended ventilation and additional passive aeration, any residual levels become negligible and continue to fade over time. By the time your sauna reaches your home, it is completely safe, with no traces of gas remaining.
