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.

How to Measure HVAC Filter

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.
