How to Know Your Filters Need Replacing
Most facilities wait until something breaks. These four signals tell you it’s time before a violation or shutdown forces the decision.
Pressure Drop Above 6″ W.G.
When airflow restriction climbs past 6 inches of water gauge, your filters are blinded. Energy costs rise and capture efficiency drops — often before your pressure gauge alarm triggers.
Visible Stack Emissions
Any visible dust or particulate at the exhaust point is an immediate EPA and OSHA compliance failure. If your stack is smoking, you’re already in violation — don’t wait for the inspection.
Worker Air Quality Complaints
Dust migrating from collector back into the plant points to filter failure or bypass. Beyond the health risk, it’s a leading indicator of a system that won’t survive an OSHA inspector’s walk-through.
Failed Compliance Inspection
A DHA or OSHA inspection finding related to your collector is the most expensive way to discover a filter problem. Our pass-or-free guarantee means we fix it at no charge if a system we specify fails.
Filter Media Selection Guide
Your dust type, operating temperature, and moisture conditions determine which media works — and which will fail. Here’s what each option handles well.
Polyester Felt
The workhorse for general manufacturing applications. Handles most dry dust streams effectively at temperatures up to 275°F. Cost-effective, readily available in custom sizes.
Max 275°FPolypropylene
Strong moisture and chemical resistance makes this the right call for food processing, pharmaceutical applications, and any process with condensation risk or acid gas presence.
Max 200°FPTFE Membrane
For sticky, hygroscopic, or very fine sub-micron dust. The membrane surface prevents depth-loading and keeps pulse cleaning effective. Highest efficiency at 99.999% rated capture.
Max 350°FNomex / Aramid
The standard for hot-side metal recovery and high-temperature process applications. Continuous service to 400°F with excellent dimensional stability under thermal cycling.
Max 400°F continuousP84 (Polyimide)
When you need both high heat and chemical resistance, P84 handles what Nomex can’t. Common in waste incineration, chemical processing, and high-temperature metal applications.
Max 450°FFiberglass
Extreme heat applications — cement kilns, power generation, refuse incineration. Handles continuous temperatures up to 500°F+ and resists most corrosive gas environments.
Max 500°F+Support Cage Options
The cage keeps your filter bag in shape under pulsing pressure. Choosing the wrong material accelerates bag wear and shortens filter life.
Galvanized Steel
Standard for most dry applications in normal temperature and humidity ranges. Cost-effective with good structural rigidity. Available in 5, 10, and 20-wire configurations to match your bag length.
304 / 316 Stainless Steel
Required for corrosive environments, food-grade applications, pharmaceutical manufacturing, and any process with acid gas or moisture exposure. 316 provides additional chloride resistance.
Epoxy-Coated Steel
A cost-effective middle ground between galvanized and stainless. Adds a corrosion-resistant coating layer for moderately aggressive environments where full stainless is over-spec.
Quick-Release Top-Load
If your facility changes filters frequently, this configuration cuts changeout time significantly. No tools required at the bag-to-cage connection. Popular in high-production woodworking and food processing.
How to Order Your Replacement Filters
