At Shandong Baodian Electronic Technology Co., Ltd., we prioritize the health and safety of every customer using our sauna products. We recently completed an independent indoor air quality test for our sauna room, and the results confirm that our sauna meets and exceeds national standards for safe use.

 

 

The test was conducted by Henan Boqi Testing Technology Co., Ltd., a certified CMA laboratory (Certificate No.: 241603100073, valid until 2030). The report (No.: BX/SK202509200) was issued on September 10, 2025, with the formal testing performed from September 9 to 10, 2025.

 

 

The core indicator tested was formaldehyde, using the national standard method GB/T 18204.2-2014, Section 7.2 (Phenol Spectrophotometric Method) with a 723N visible spectrophotometer.

 

 

 

This low formaldehyde level is the result of our strict selection of natural wood and professional kiln drying and heat treatment process. We use premium red cedar, hemlock, and spruce, which are naturally low in volatile organic compounds. Combined with our high-temperature thermal modification process, we eliminate residual chemicals and ensure the wood is safe to use in high-temperature sauna environments.

 

 

Our commitment to indoor air quality means you can enjoy your sauna without worrying about harmful fumes. Every product we deliver is designed for long-term health and comfort, backed by third-party verified test results.
