Airtight. By Design.

We changed the filtration equation.

Meet TrueSeal, Joe Fly's proprietary filtration technology designed to eliminate air bypass while reducing material, labor and waste.

By rethinking how air filters work within your filtration system, TrueSeal helps facilities achieve more effective filtration with less hassle and potentially lower total operating costs.

Works with your existing filtration system.

Even the most efficient filter media can't perform as intended if air is passing around the filter instead of through it.

Traditional filtration systems can allow air to bypass the filter through gaps around the frame. That means some air may never pass through the filtration media.

TrueSeal was developed to address this problem.

Our proprietary design eliminates air bypass while creating opportunities to reduce the amount of filter material required, the labor involved in replacements and the waste generated over time.

A Better Filter Starts With a Better Seal.

Cleaner air. Lower costs. Less hassle.
