Recently, due to the "Wuhan pneumonia" outbreak, people are in a state of panic everywhere. Wearing masks has not only become a national movement but is also in short supply. Since many visiting customers have been curious about how we make masks, we would like to share with you the methods that Sandima Office currently uses to "regenerate" masks, which can effectively extend the life of masks for reuse.
Previously, I shared with you the " Ozone Genie " developed using the Ultimaker 3D printer (further reading: Full Development Record! Mini Home Ozone Generator! ). This mini home ozone generator has a US patent and is made in Taiwan. Our office uses the " Forest Ozone Generator ," which is more suitable for larger spaces . It allows you to set the desired ozone emission level and operating time. Since the air outlet can produce an ozone concentration of about 50ppm, we use plastic bags to seal the masks and then sterilize and disinfect the used masks in turn.
Foreign research papers have confirmed that ozone is effective in sterilization and deodorization, and it is effective against viruses including SARS-like viruses. We discovered its advanced use during this pandemic. Generally, European and American countries stipulate that the ozone concentration in the air should be 0.05 ppm. When high concentrations of ozone are released from air vents, they will dilute into the air. Therefore, as long as the recommended space size or floor area is followed, it can be used with confidence ( in a small, enclosed space, ensure that no one or pets are in the same space ). Both the small " Ozone Genie " and " Ozone Genie " have passed SGS testing and certification.
In a 20-ping (approximately 33 square meters) space like the SanDiMa conference room, just one unit can effectively kill pathogens in the air. Because it eliminates germs through oxidation-reduction, it leaves no residue of cleaning agents or other chemicals that could harm the human body. We also usually use a fan to help diffuse the scent to every corner of the office. When turned on, it will emit a faint forest scent, which is more effective at deodorizing than air fresheners.
The smaller " Frost-Eliminating Genie XTB-360 " is more suitable for use in rooms, shoe cabinets, refrigerators, or cars. It is very effective in eliminating smoke or odors and sterilizing and preventing diseases. It has been tested and can effectively kill at least 84% of bacteria in the air. The two different models are suitable for different places. The " Frost-Eliminating Genie XTB-360 " is suitable for general homes, car interiors, and small apartments. The " Oxygen Genie XT-1000 " with free adjustment is more suitable for hospitals, clinics, and office spaces.
SanDima specializes in 3D printing and processing equipment . In response to the needs of the pandemic and customer inquiries, we are recommending this SanDima ozone sterilizer , which is used in our offices. It is now available for order on our online store (only a limited number of items are in stock; please call for inquiries if you have a large demand from medical units).
Our colleagues and I are currently using this method to sterilize and disinfect our masks. Only a few masks are needed for reuse, and we use them regularly to eliminate potential bacteria and viruses in the office. If you have similar equipment at home, please use the same method for disinfection. However, epidemic prevention cannot rely solely on masks; it's still important to combine this with avoiding touching your mouth and nose, frequent handwashing, and exercising to boost immunity. We hope everyone stays safe and healthy, and we can get through this together.
