ASHRAE Standard 52.1-92 and ASHRAE 52.2-2007 per Appendix J|Classified UL 900 Class 2

• 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

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 3 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 3 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 8 3 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.
