Overview

VariCel® filters are high-capacity, extended surface, supported box filters designed for a wide range of applications. Their rigid construction and supported pleat media ensure durability, even in harsh operating environments with variable air volume, turbulent airflow, high humidity, and exposure to moisture. These filters are particularly suited for seacoast installations and high-dust environments.

Key Features

  • Available in MERV 15, MERV 14, MERV 13, and MERV 11 efficiencies
  • Engineered for excellent performance in challenging conditions
  • MERV 14 available with antimicrobial treatment
  • MERV 15, MERV 14, and MERV 13 available for high-efficiency commercial applications
  • UL Classified for reliable performance

Dual-Density Media for Cost Savings

The dual-density media design, with coarser fibers on the air entering side and finer fibers on the air leaving side, maximizes dust-holding capacity, extending filter life and reducing operating costs. VariCel filters are water-resistant, making them ideal for humid conditions.

Designed to Improve Indoor Air Quality (IAQ)

VariCel filters, particularly in MERV 14 and MERV 15 ratings, effectively capture fine particles, including bacteria and viruses, improving indoor air quality. The MERV 14 version is also available with antimicrobial-treated media to preserve filter integrity throughout its lifespan.

Product Options

  • Available in 12″ and 6″ depths for different air flow needs
  • Optional faceguards made of galvanized or aluminized steel
  • Factory-installed gaskets for easy installation
  • Vinyl-coated separators for corrosive environments

Performance Data

  • Operating temperature limits: up to 900°F, depending on the filter type
  • Recommended final resistance: 1.5″ w.g. (1.2″ w.g. for HT filters)
  • Tested in accordance with ASHRAE Standard 52.2
