MicroMAX PL6™


MicroMAX PL6™

MicroMAX PL6™

The MicroMAX PL6™ is an extended surface, mini-pleat air filter engineered to provide maximum performance and prolonged filter lifecycles in all types of commercial and industrial HVAC applications.


  • MERV 11-15 performance rating
  • Compact design saves space
  • Durable plastic frame
  • Reduces freight and handling
  • Incinerable
  • Antimicrobial media available


All-Plastic Compact Design

The MicroMAX PL6 is manufactured in a 6" deep, durable plastic frame designed to replace almost any 12" competitive high efficiency filter.  The lightweight all-plastic frame installs easily into side-access housings or front-load holding frames and is an ideal choice to replace bag filters and other heavier box-style rigid filters.  The lightweight, compact design also helps lower shipping costs and the need for excess inventory space.  It is also a preferred choice in applications where incineration is the desired means of disposal.


Dual-Density Filter Media

The media used in MicroMAX PL6 mini-pleat filters is composed of micro-fiberglass paper, treated with a specially-formulated, water-repellent binder. Millions of fibers are constructed into a graded density mat, with coarse fibers upstream and finer fibers on the air-exiting side. This dual-density media combined with a mini-pleat design ensures full media utilization, which results in higher dust holding capacity and extended filter life in a compact configuration.

The MicroMAX PL6 is also available with antimicrobial-treated media.


Great Performance in a Compact Design

The MicroMAX PL6 offers the same media square footage and comparable performance of normal 12" final filters, but in a compact design.  The MicroMAX PL6 mini-pleat media pack utilizes thermoplastic glue-bead separators to ensure consistent media spacing and aerodynamic airflow.
