HVAC Bag Filters | Commercial Pocket Filters MERV 11–15 ⁽²³⁹⁾

High-Performance HVAC Bag Filters

Bag filters—also called pocket filters—are extended-surface commercial HVAC filters engineered for environments with heavy particulate loads and long service intervals. Unlike flat panel filters, bag filters use multiple fabric pockets to dramatically increase media surface area, which means higher dust-holding capacity, lower pressure drop, and filter changes measured in months rather than weeks.

Where Bag Filters Belong

Commercial AHUs — office buildings, retail centers, schools
Hospital & healthcare HVAC — typically as a final or secondary filter
Industrial facilities — manufacturing, food processing, warehouses
Hotels & hospitality — large-volume air handling with variable occupancy

Available Efficiencies

Bag filters are available from MERV 11 through MERV 15, with MERV 13 and MERV 14 being the most common commercial specifications for ASHRAE-compliant IAQ. Pocket counts range from 4 to 10+ depending on frame depth and airflow requirements.

Typical Brands We Stock

Never Compromise on Quality When It Comes to the Air You Breathe

Forced air systems, including furnaces, air conditioners, and heat pumps, circulate warm or cool air throughout your home via ducts and vents. These systems utilize filters to prevent dust and debris from being distributed along with the conditioned air. These filters not only enhance indoor air quality but also safeguard your forced air system.

When filters become overly clogged with particles, they diminish your system's efficiency, leading to increased heating and cooling costs, due to the hindered air movement from your heating system into your home or business. A severely clogged filter can cause a build-up of hot air near your heating system, triggering its emergency shut-off mechanism and leading to intermittent operation. Furthermore, clogged filters can exacerbate the presence of mold, dust, and other allergens in your home.

What MERV Rating Is Right for You?

MERV (Minimum Efficiency Reporting Value) measures how well an air filter captures particles. A higher number means better filtration—but it must still be compatible with your HVAC system. Here's a breakdown to help you choose the right filter for your home or business.

MERV 1–4

Basic protection. Captures larger particles like dust, lint, and pollen. Minimal airflow resistance. Best for older systems or basic residential use.

✔ Highest airflow
✘ Does not trap fine particles

MERV 8

Great balance of airflow and filtration. Captures mold spores, dust mites, pet dander, and pollen. Most common choice for residential HVAC systems.

✔ Good airflow
✔ Effective for everyday air quality needs

MERV 10

Enhanced dust-holding capacity and improved particle removal compared to MERV 8. Traps finer particles like mold spores, hair spray, and fabric fibers.

✔ More efficient than MERV 8
✔ Still maintains strong airflow

MERV 11

Captures smaller particles like auto emissions, smoke, and some airborne bacteria. Ideal for homes with pets or allergy concerns. Moderate impact on airflow.

✔ Great for allergies
✘ May reduce airflow in older systems

MERV 13

Highest residential-grade filtration. Captures airborne bacteria, tobacco smoke, and fine particles. Recommended for asthma, smoke exposure, or medical-grade needs.

✔ Best indoor air quality
✘ Not suitable for all systems without airflow evaluation

How to Measure HVAC Filters

To find the correct replacement, measure the length, width, and depth of your existing filter. Most filters are labeled with a nominal size (like 16x24x1), which is a rounded number—actual measurements are often slightly smaller. Accurate sizing ensures a proper fit and helps maintain airflow efficiency.

Step 1: Remove Old Filter

Turn off your system and remove the existing filter. Look for printed dimensions on the frame—this is usually the nominal size.

Step 2: Measure Actual Size

Use a tape measure to get exact dimensions (length × width × depth). Round down to the nearest 1/8" if needed—example: 15-5/8" × 23-5/8" × 3/4".

Step 3: Match or Order Custom

If your measurements don’t match a standard size, we offer custom filters made to your exact dimensions.
