Research and Development

Our home is a sacred place. It’s where we relax, eat and sleep. But we’re not the only ones living there. We share it with a multitude of uninvited and invisible microorganisms – dust mites, bacteria and viruses. These live pathogens can be harmful to our health and are often the cause of the allergic and asthma symptoms that affect many people worldwide.

RAYCOP Research and Development continually conducts laboratory studies to better understand how to most effectively combat the hazards of live pathogens. This internal research led to the development of RayClean Technology®, which combines UV sterilization, vibration, suction and filtration to efficiently sanitize the places throughout the home where live pathogen populations are most numerous.

Understanding What is Around Us

Dust Mites – Even though you don’t realize they are there, dust mites can be found in every corner of our home, including bedding, sofas, carpets, chairs, and even curtains. Dust mites leave behind trails of allergenic waste as they move. When these allergens are at a significant concentration level, the risk of individuals developing asthma and allergies increases.

Dust mites have short life spans. Typical male dust mites live between 10-19 days, and female dust mites can live up to 70 days. In these 10 weeks, they produce approximately 2,000 decal particles and an even larger number of partially digested enzyme-covered dust particles which are one of the common causes of allergies in humans. RAYCOP’s R&D laboratory has found that the continuous application of UVC light, used in our patented RayClean Technology®, significantly impacts the hatch rate of dust mite eggs, and is the most effective way to eliminate dust mite matter. Third-party laboratories have tested the RAYCOP allergen vacuum and confirmed its effectiveness.

Bacteria – Bacteria are tiny single cell microorganisms, usually a few micrometers in length, that normally gather in millions. Bacteria can be beneficial as well as detrimental to human health. Commensal bacteria, which share space and resources with our bodies, tend to be helpful. Other bacteria can cause infections, and are frequently brought back home from public places such as schools, gyms and offices. Two of the most common bacteria found living in our beds are E-Coli and Staphylococcus. RAYCOP laboratory tests show that approximately 1-2 seconds of exposure to UV light can eliminate roughly 99% of these bacteria.

Studies were conducted on E-Coli and Staph during the testing process.

UV Sanitation – UV light is electromagnetic radiation with wavelengths shorter than visible light. UV can be separated into various ranges, with short-wavelength UV (UVC) considered “germicidal UV.” At certain wavelengths, UV is mutagenic to bacteria, viruses and other microorganisms, breaking down the molecular bonds within microorganismal DNA and producing thymine dimers that can kill or disable the organisms. The practice of UV sanitation has been accepted since the mid-20th century. It has been used primarily in medical sanitation and facilities that require higher levels of sterilization.
