Flanders has led the world in filter media development and the application of high efficiency filtration for over 60 years. Originally introduced in 2004, the industry's first MERV 8 filter operating solely on mechanical means has now been improved! Since 2004, other manufacturers have altered media blends to meet the LEED and market driven demand for non-electret MERV 8 filters. This has led to pressure drop increases in their filters of 25% or more, Utilizing a unique new fiber technology, our research and development Team has now achieved multiple goals of maintaining MERV 8A performance at a resistance that is 40% lower than competition. At the same time, the LPD's dust holding capacity remains the highest in the industry.

Flanders® Pre Pleat 40 LPD Pleated Air Filter, Series: 80055, Non-Woven Synthetic Media, 20 in Width, 30 in Height, 1 in D, MERV: 8, 30 to 35 % Filter Efficiency, 13 Pleats per Linear Feet, 300/500 fpm Rated Velocity, 93 % Average Arrestance, 180 deg F

• Media is made of 100% synthetic non-woven proprietary media that can be recycled
• The media is supported by an expanded metal continuously laminated on the air leaving side to provide pleat stability while eliminating flutter
• Pleat design is a V-pleat that aids in pressure drop while reducing energy cost and allowing total media usage and provides maximum airflow and dust holding capacity
• Frame is a two-piece construction, made of a heavy-duty 24-point moisture-resistant material
• Diagonal and horizontal support members are bonded to the media on both sides
• Highest dust holding capacity and lowest pressure drop in the industry
• 40% low pressure drop
