Founded in 2009 in Johnson City, Tennessee, Greentech Environmental is a leader in air purification systems for both consumer and commercial applications. Greentech has always taken a multi-technology approach to solving the toughest indoor air quality problems and does so again with our revolutionary new Greentech Filters+. We start with Nanofiber technology to create a true mechanical filter with improved airflow and low pressure drop that maintains its MERV rating throughout the life of the filter. Then we combine it with our advanced, patented ODOGard to destroy and eliminate odors and VOCs better than any filter on the market. Designed with an eye on sustainability, our filters are recyclable and contain about 50% less plastic than traditional filters, meaning Greentech Filters+ are better for the environment, they help HVAC systems work smarter, not harder.
