Bag & Pocket Air Filters
Engineered for high-performance HVAC systems, our bag and pocket air filters deliver high dust-holding capacity, low pressure drop, and long service life — even in demanding commercial and industrial environments.
Pocket air filters — also known as bag filters for HVAC systems — feature deep, flexible pockets that dramatically increase filtration surface area within a standard housing footprint. More surface area means greater dust-holding capacity, longer service intervals, and more stable airflow, making them a strong fit wherever heavy particulate loads or short filter life are a recurring challenge.
Where system depth allows, pocket filters are often the preferred specification for commercial air handlers, industrial ventilation, and high-occupancy buildings. They're equally at home in more critical environments — cleanrooms, data centers, hospitals, and life science facilities — where consistent filtration performance directly impacts equipment reliability and occupant health.
Available in multiple MERV ratings, pocket depths, and sizes, Rensa's bag filters are designed to extend the life of downstream systems and reduce total cost of ownership over time.
Three proprietary media technologies set Rensa's pocket filters apart.
Our Revolution Pocket Filter uses Pocket Wave media, engineered to hold significantly more dust in heavy, abrasive environments — proven in data center field testing.
And our Alpha Supreme (AS Series) uses extended-surface synthetic media for high dust-holding capacity and a low initial pressure drop, well-suited for commercial, healthcare, and education environments.
Our Magnes Bag Filter — the world's first bag filter engineered specifically for data centers — uses 3D Dimpled media rated MERV 11 to deliver up to 2x the filter life and up to 30% energy savings compared to conventional filters.
Whatever the application, there's a Rensa pocket filter engineered around the media technology it demands.
Particulate loads vary widely across facilities, and not every filter is built to handle the demands of modern HVAC systems. Rensa offers bag and pocket air filters with the media, construction, and size options to match the environment — not just the housing. When performance matters, pocket filters deliver clear advantages. Each filter features multiple deep pockets that expand surface area, allowing it to hold significantly more dust without a steep pressure drop — meaning cleaner air, less stress on your HVAC system, and better protection for the equipment and people downstream. From high-traffic commercial buildings and server rooms to healthcare facilities and industrial operations, our bag and pocket filters are built to trap dust, pollen, mold spores, and a broad range of airborne contaminants with proven, durable performance.
We switched to Rensa pocket filters two years ago and filter change-out frequency dropped significantly. Our maintenance team spends a lot less time in the field.

The Revolution Pocket Filter has extended our service intervals and reduced labor and replacement costs considerably. One of those spec decisions that pays for itself.

Rensa & AFC's exhaust pocket filters outlast everything else we've used — high paint-holding capacity, consistent pressure drop, and they hold up through long production runs.
