Here’s how to choose between MERV 11 and MERV 16 filters for your home.
When shopping for the right air filter, you’ve probably noticed a label that says “MERV 11” or “MERV 16.” That number is one of the most important details to look at when choosing a filter that keeps your home’s air clean and your HVAC system running efficiently.
At Bell Mechanical, we know choosing a filter can be confusing. Here’s what MERV ratings really mean, how they affect your home’s comfort and air quality, and how to pick the right one for your needs.
What Is a MERV Rating?
MERV stands for Minimum Efficiency Reporting Value — a standard created by ASHRAE (the American Society of Heating, Refrigerating and Air-Conditioning Engineers).
It measures how well an air filter can capture particles of different sizes.
- Higher MERV = finer filtration (captures smaller particles like smoke or allergens).
- Lower MERV = basic filtration (captures larger dust and lint).
So, that number on the box tells you how much protection your filter is really giving your air and your lungs.
Comparing MERV 11 vs. MERV 16 Filters
| MERV Rating | What It Captures | Pros | Things to Know |
|---|---|---|---|
| MERV 11 | Dust, lint, pet dander, mold spores, and common allergens (down to 1 micron) | Great balance of air quality and system airflow; helps reduce allergy symptoms | Recommended for standard HVAC systems — no special modifications needed |
| MERV 16 | Ultrafine particles like smoke, bacteria, and some viruses (down to 0.3 microns) | Delivers hospital-grade filtration and the cleanest possible indoor air | Provides advanced purification—ideal for allergy relief and healthier indoor air |
Which One Is Right for You?
- Choose MERV 11 if you want reliable, high-quality air filtration that protects your system and keeps your air fresh — perfect for most households.
- Choose MERV 16 if you need advanced purification for health concerns, have pets and allergies, or want top-tier indoor air quality throughout your home.
