GreenTech Environmental and CASPR Group of Dallas, Texas announce an initiative with hospitals nationwide to install duct-mounted surface and air purification systems which protect both patients and staff by providing continuous disinfectant technology. The next installation will be conducted on Tuesday, March 24,2020, at St. Luke’s UnityPoint Hospital in Cedar Rapids, Iowa by CASPR technicians. The installation is happening ahead of schedule, necessitated by the current COVID-19 pandemic.


The CASPR Medik product was developed in a collaboration between CASPR Group and GreenTech Environmental, specifically for the healthcare market to re-create the same processes found outside that reduce outdoor pollution. The technology’s  purification actively seeks out and reduces indoor air pollution. Unlike other technologies which require the use of strong chemicals or high-intensity UV light, both of which must be applied in unoccupied spaces, the CASPR Medik operates continuously while spaces are occupied.

GreenTech manufactures the CASPR Medik in the company’s Johnson City, Tennessee, manufacturing facility. The company has significantly increased production to meet demand for the CASPR Group for use in hospitals as well as other healthcare environments nationwide.

“In this unprecedented time of world pandemic, people are looking for solutions that provide addition purification for themselves and their loved ones. GreenTech has dedicated our company to developing active air purification technologies. Unlike filters which can be ineffective at trapping or inactivating viruses, active technologies reduce particles and break down other irritants by using oxygen and hydrogen-based oxidizers.”
