Space Guardian — 3-in-1 Humidifier, Sterilizer & Purifier Product Features: The core function of this product is an innovative space purification technology based on BDD technology, which effectively kills airborne bacteria and viruses that cause respiratory infectious diseases, such as the COVID-19 virus. It also efficiently decomposes and eliminates second-hand smoke pollutants in enclosed spaces, particularly those adhered to walls and furniture surfaces. The core technology converts ordinary water into water containing ozone and hydroxyl radicals. Through ultrasonic atomization, the resulting mist is evenly dispersed into the air and onto surfaces where bacteria, viruses, and cigarette odors are present, rapidly inactivating pathogens and breaking down odorous compounds. The entire cleaning process requires no additional chemical reagents or filter materials. Core Technology Principle: BDD Electrochemical Advanced Oxidation Technology. Utilizing the world's most advanced BlueBDD thin-film electrode, this system generates ozone mist at a controllable concentration under a low-voltage DC electric field of 24V. The mist is then introduced into the air, where the ozone rapidly eliminates bacteria and viruses on surfaces and throughout the space. It achieves a sterilization rate of 99.9% within 30 minutes. Moreover, it can quickly oxidize and decompose gaseous pollutants such as nicotine, benzene, formaldehyde, etc., with a degradation rate of 99.2%, and produces no secondary pollutants during the entire process. Safety: The electrolytically generated ozonated water automatically reverts to plain water within 3 to 5 minutes after production. It has no impact on the environment and causes no harm to human health.

Field Test: The field test was conducted in the office of a business owner, a heavy smoker with 30 years of smoking history, who smokes constantly in the office. Both visiting clients and employees had to endure the harmful effects of second‑hand smoke. The office walls had even been stained yellow by cigarette smoke. After using this product, the indoor cigarette odor was significantly reduced. With continuous use, the office air became noticeably fresh and clean, effectively curbing the spread of second‑hand smoke.
