About Air Filter Efficiency Ratings

Compare MERV rating, efficiency, and particle size to find the right filter for your location—from warehouses and offices to hospitals and labs.

Panel Air Filters

Pleated Panel Air Filters

The pleats create a large surface area for filtering without reducing airflow.

Made-to-Order Pleated Panel Air Filters

Select the dimensions you need for custom-sized frames.

Snug-Fit Panel Air Filters

The filter material extends beyond the frame for a tight fit, creating a seal to prevent air from bypassing the filter around its edges.

Mildew-Resistant Snug-Fit Panel Air Filters

A compound inhibits mildew, mold, and fungi growth.

Snug-Fit Multi-Panel Air Filters

Stop unfiltered air from passing between panels or around filter tracks.

Reusable Electrostatic Panel Air Filters

An inherent electrostatic charge attracts dust and particles to these filters.

Odor-Removal Panel Air Filters

Carbon granules in these filters remove odors. They are pleated to maximize filtering surface area without reducing airflow.

Strong-Odor-Removal Panel Air Filters

Eliminate heavy odors with these filters that have 30 times the odor removing ability of standard odor-removal air filters.

Ultra-Efficiency Odor-Removal Panel Air Filters

Clear the air of fine particles and odors caused by high levels of pollution, such as wildfire smoke.

Air Filter Rolls and Pads

Air Filter Rolls

Cut these rolls to the size you need.

Air Filter Pads

Cut these pads to the size you need.

Reusable Air Filter Rolls

Cut these washable, reusable rolls to the size you need.

Reusable Air Filter Pads

Wash and reuse these pads. Cut to the size you need.

Electronic Equipment Air Filter Pads

Designed for use with electronic equipment, these pads can withstand prolonged exposure to heat and humidity.

Odor-Removal Air Filter Rolls

Carbon granules inside these filters remove odors from the air. Cut them to the size you need.

Odor-Removal Air Filter Pads

With a higher carbon concentration than odor-removal air filter rolls, these pads handle heavier odors.

Air Filter Rolls for Automatic Roll Machines

Replace the filter roll in your automatic filtering equipment.

Odor-Removal Box Air Filters

Carbon granules in these filters remove odors from the air. The rigid frame won’t bend or twist from sudden changes in airflow, such as those created by variable air volume systems.

Cube Air Filters

Prevent air from bypassing your filter. These filters are self-sealing thanks to the filter material that fully encloses the metal frame.

Process Filtering

Air-Intake Filters

Stop dust and other contaminants from entering your process and equipment. Use these filters on blowers, compressors, engines, and in hydraulic systems.

Compact Air-Intake Filters

Clean the air going into small blowers and air-powered equipment in tight spaces.

Corrosion-Resistant Air-Intake Filters

Made of polypropylene, these filters can be used in damp environments where corrosion is a concern.

Vacuum-Rated Air-Intake Filters

Typically used on vacuum pumps, these filters ensure that clean air is going in and coming out of your system.

High-Vacuum Air-Intake Filters

Install these filters between your high-vacuum chamber and the inlet of your pump to remove dust, water vapor, and other contaminants from the system and protect the pump. Commonly used in vacuum-furnace and coating applications, they have a polyester filter element that traps particles as small as 5 microns.

Compact Vacuum-Rated Air-Intake Filters

Use one of these compact filters in a tight spot, or combine up to ten for a manifold application.

Exhaust Filters/Mufflers for Dry High-Vacuum Pumps

Purify exhaust fumes while silencing the noise from your oil-free high-vacuum pumps.

Inline Mufflers for Air and Inert Gas

With a threaded connection on both ends, these mufflers can be installed anywhere in your line.

Moisture-Eliminating Breather Vents

Keep moisture, dirt, and debris from entering your oil reservoirs.

Dust Collectors

Dust Collector Filter Bags and Cartridges

When you need to replace your dust collector’s bag or cartridge, match up the specs to one that we have.

Drum-Mount Two-Stage Dust Collectors

Mount these powerful units on a drum for two-stage collection. In the first stage, larger particles fall into the drum; in the second stage, smaller particles go into the filter bag, resulting in less wear on the blower and filter bag. These collectors are 99% efficient for particles 10 microns and larger.

Masks and Respirators

Spark-Resistant Disposable Respirators

Often worn for welding and grinding, these respirators resist igniting from flying sparks and flames. Made of flame-retardant polyester, they meet ASTM D2859 standards for flame resistance.

Clean Room Disposable Masks

Made of low-linting fabric, these masks won’t shed fabric particles that could contaminate your clean room. They come double bagged and are suitable for use in clean rooms rated to both Federal Standard and ISO classes.

Reusable Masks

An alternative to disposable face masks, these protective masks can be washed and reused multiple times.

Fan Shroud Air Filters

These filters fit over fans with round guards to trap dust and debris, keeping contaminants out of the air and off of your fan.

Filters for Spray Booths

These economical filters hold contaminants while allowing proper airflow.

High-Efficiency Filters for Spray Booths

The most efficient spray booth filters we offer, these filters are made of polyester for moisture resistance.

Corrosion-Resistant Washdown Threaded Breather Vents

Corrosion-Resistant Washdown
Threaded Breather Vents

Rated NEMA 4X, these vents provide protection from washdowns, corrosion, and power jets of water.
