If millions to be spent on air filtration22 Dec 2021 11:09
then Volz is the known leader in the global industry and NNN are our partner. Why use normal air filters when you can install one with filters that actually kill Covid. There’s no competition. This has to be the next big trend in Covid stocks - forget testing and treatments as the world learns to live with Covid this will be regulation in all buildings, airports, offices, schools, trains, airplanes, cruise ships, universities across the world - mind boggling amount of revenue to be made. And the technology used is patented plus a further US patent approval coming too.
