Variflow II-M is a high-efficiency mini-pleat air filter for commercial and industrial use. The filter is available in two ratings: 90-percent to 95-percent MERV 14 models and 60-percent to 65-percent MERV 11 models. It is an extended surface, rigid cell filter with metal cell sides and an ultra-fine, depth-loading microglass fiber media. A rigid pack design makes the filter ideal for the turbulence, variable air volumes, and frequent fan shutdowns common in industrial and commercial air-handling systems, the company states.
