Where clean air is needed, an air filter is usually not far away. In the last decade, the filtration industry has made tremendous progress in filter technologies. With new materials and designs, advances in nonwoven fabric manufacturing, and pleating methods, as well as new developments like nanofiber layers and coatings, filters have become more efficient, reliable, and compact. Demands on the filtration industry are also changing. It’s no longer solely about filter efficiency and dust-holding capacity; with soaring energy prices and increasing awareness of sustainability, filter media are expected to contribute to lower energy consumption.

Do you hire other companies to complete jobs in your workplace? Did you realize that you could be liable for labor violations that the company commits while working there? There are two pending and one recently decided case that will alter how franchisees, general and sub-contractors, and other companies operate.
