Puracell II LR Mini-Pleat Box Filter - 12 x 24 x 4

This is a 4-inch mini-pleat filter Box Configuration

engineered to provide the high-level filtration of a much larger box filter while maintaining an incredibly low pressure drop. By reducing the resistance your HVAC system faces, the Puracell II LR helps lower energy consumption and extends the life of your equipment.

Low Resistance (LR) Technology: Specifically engineered to provide the lowest possible pressure drop, allowing your HVAC fans to run more efficiently and lower utility costs.
Compact 4-Inch Depth: Delivers high-efficiency filtration MERV 15 in a slim profile, making it an ideal replacement for older, bulkier 6-inch or 12-inch rigid cell filters.
High Media Surface Area: Utilizing advanced mini-pleat technology, these filters contain significantly more media than standard pleated filters, leading to superior dust-holding capacity and a longer service life.
High Moisture Resistance: microglass media ensures performance even in high-humidity environments.

The Puracell II LR is designed for environments where high-efficiency air cleaning and energy management are critical, such as:

• Commercial Office Buildings (Variable Air Volume systems)
• Hospitals and Medical Centers
• Pharmaceutical and Government Facilities
• Universities and Schools
• Pre-filtration for HEPA cleanroom environments
