Filtco Replacement Filters Overview

Filtco’s replacement brand of high-quality, competitively priced activated carbon filters is designed to fit all major manufacturers of ductless fume hoods. We manufacture each filter using precision-formed casings and tightly packed, premium-grade carbon media to ensure reliable performance and long-term durability.

Filtration Efficiency

Filtco filters effectively control fumes and odors from chemical processes, outdoor air pollution, and smoke. We ensure maximum efficiency by using high-quality carbon media, durable casings, and precise manufacturing methods. This ensures consistent airflow and performance across the filter’s full-service life.

Carbon Media

Filtco uses carefully sourced, high-quality activated carbon. 

Carbon Filter Casings

Filtco filter casings are made from reinforced thermoplastic, providing strength, chemical resistance, and impact durability in a lightweight design. Their chambered construction prevents the carbon from shifting. This ensures uniform media distribution and maintains the structural integrity of the filter.

Carbon Filter Assembly

Each filter is tightly packed with activated carbon to prevent settling during shipment and use.

Filtco models that include pre-filters (particle or HEPA filters) come with no additional assembly. See Manufacturers Filter Types below for more details. The assembled carbon filter, with attached pre-filter (if applicable), is then packed into a heat sealed plastic bag and durable box for shipping.

Filter Maintenance is Essential for Proper Performance

Proper filter maintenance is essential to ensure safe operation and peak performance. All activated carbon filters have a limited capacity to adsorb hazardous vapors. Once that capacity is reached, filters must be replaced.

Always follow the replacement intervals specified by your ductless fume hood manufacturer. Delayed replacement can result in exposure to harmful vapors—even from commonly used chemicals.

Filtco Chemical Guide

The Filtco Chemical Guide helps users identify the correct filter based on the chemicals used in their applications. Filters are recommended based on retention capabilities to support safe, effective operation of ductless fume hoods.

We encourage reviewing the guide prior to purchase to ensure the right match. Performance may vary based on environmental and operating conditions.
