Drop-in Filters

Forward-looking system solutions for industrial air filtration. Our filters range from general indoor air and cleanroom through filtration processes for automotives. Our optimized filtration solutions offer a better air quality for all of your needs.

The Solution

Advanced Odor Control PuraFilter™

This combination molecular and particulate filter integrates Purafil® patented media (SP Blend) into a particulate filter to remove odors and pollutant gases, while providing the same level of particulate control. Our SP Blend enhanced pleated filter offers a low pressure drop for less restricted airflow and better energy efficiency.

MERV 13 PuraFilter

• MERV 13 Efficiency Filters
• Available in 1″, 2″ & 4″ depths
• Advanced, dual-component, synthetic air media
• Charged fibers immediately trap contaminants
• Resulting dust cake enhances
• Promotes high filtration during entire life cycle
• High efficiency filtration in compact depth


The Purafilter® is a combination chemical and particulate filter that integrates Purafil® patented dry-scrubbing media into a non-woven fiber matrix. Partnered with an HVAC system, Purafilters help meet building codes and regulations requiring outdoor air cleaning for PM-10, PM-2.5, and ozone. They replace existing particulate filters in retrofit or rework applications as well as being used in new construction. Also available in a high efficiency option.


The PuraGRID® is a modern new filter design that supplies a large amount of chemical filtration with a minimal amount of pressure drop. This filter offers increased operational performance and energy savings for many indoor applications. The PuraGRID can be constructed with several different chemical medias to tailor the solution to specific needs.

PuraWard PuraFilter

• Available in 1″, 2″ & 4″ depths

Filter protected by an EPA-registered antimicrobial additive. §Patent number US 9,370,763 B2

The Sachet

Designed for the refrigerator, a sachet increases the shelf life of fruits and vegetables from days to weeks. It eradicates ethylene, a naturally occurring gas that causes fruits and vegetables to ripen prematurely. Food stays fresher, longer.
