We have worked with Dave Goodall for years & trusted his experience to provide the right solution for us. We were given the option to trial the MedicAir®air purification device before making any commitment. By using these units from Pro-Tect, we hope to reduce the amount of time that our classroom windows are open fully. As well as providing an additional layer of safety for staff and pupils it also helps to create a more comfortable working and learning environment for everyone. John McGrath
