It can be challenging to keep up with all the cleaning and sanitizing you need to do around the house. But with the Safety 1st Stay Clean Humidifier, we’ve made things a bit easier for you. Our self cleaning humidifier stays clean, requiring less work from you, with a little help from Vyv’s antimicrobial LED technology that kills* 99.9% of viruses & bacteria and prevents mold growth*.The Vyv StoryVyv is a health technology company delivering a new class of antimicrobial light that reduces the impact of microbes in homes, public places and industries. Unlike harmful chemicals or dangerous ultraviolet (UV) light, Vyv’s finely tuned, patented light continuously kills microbes and creates an inhospitable environment to inhibit their growth on surfaces. Leaving your humidifier plugged in, with the Vyv LED lights on, gives you the peace of mind that your humidifier is staying clean.*+99.9% of MRSA and E coli bacterial concentrations killed within 24hrs; growth of mold (Aspergillus) prevented (in laboratory controlled studies with prolonged use). Testing on a non-enveloped virus (MS2 bacteriophage) showed a 99.985% reduction in controlled laboratory testing in 6 hours on hard surfaces. MRSA and E. coli showed 90%+ reduction in controlled laboratory testing in 24 hours on hard surfaces. Results may vary depending on the amount of light that is reaching the surfaces in the space where the product is installed and the length of time of exposure. Use of Vyv antimicrobial light is not intended to replace manual cleaning. ** Sanitization will only function when unit is plugged in and LED lights are on 24/7. It is normal for all but 1 LED light to turn off when the tank is removed. Use distilled water for optimal performance. *** A study by Environmental Health and Engineering (Environmental Health 2010, 9:55) shows that keeping indoor air at an RH level of 40%-60% can reduce the survival of flu viruses on surfaces and in the air compared to lower RH levels.
