A Comprehensive Guide to MERV 11 Filtration for Improved Indoor Air Quality

In today’s fast-paced world, the importance of clean indoor air cannot be overstated. With people spending a significant portion of their time indoors, it’s crucial to ensure that the air in residential, light commercial, and custom homes is free of contaminants as much as possible. Your HVAC system plays a vital role in maintaining good indoor air quality. One of the most effective ways to achieve cleaner air is by upgrading your HVAC system to include a filter with a higher Minimum Efficiency Reporting Value (MERV) rating, such as a MERV 11 filter

MERV ratings were developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to provide a standard for evaluating the efficiency of air filters. MERV ratings range from 1 to 20, with higher ratings indicating superior filtration efficiency and particle removal. MERV 11 filters are considered highly efficient, capable of capturing particles as small as 1 micron. 

Learn the concept behind MERV ratings, the benefits of MERV 11 filtration, and how our professional technicians can help improve your indoor air quality. Alaskan Plumbing Heating & Air is here to guide you through the process of upgrading your HVAC system to include a MERV 11 filter, ensuring optimal indoor air quality and performance for your unique needs.

Understanding MERV Ratings and Particle Filtration

To better comprehend the benefits of MERV 11 filtration, it’s essential to grasp the concept of MERV ratings and their role in particle filtration:

  1. MERV Rating System: MERV ratings, ranging from 1 to 20, provide a standardized measurement of a filter’s ability to capture and retain airborne particles. Higher MERV ratings signify greater filtration efficiency.

  2. Particle Size: Airborne particles are measured in microns (μm). For reference, a single human hair has a diameter of about 50-70 microns. MERV ratings are designed to capture particles within a specific size range.

  3. Efficiency: MERV ratings correlate with the percentage of particles in a specific size range that a filter can efficiently remove from the air. For example, a MERV 11 filter can efficiently remove particles in the 1.0-3.0 micron size range.

The Benefits of MERV 11 Filtration for Residential and Light Commercial Spaces

Upgrading your HVAC system with a MERV 11 filter brings several advantages to residential, light commercial, and custom home environments:

  1. Improved Indoor Air Quality: A MERV 11 filter is highly efficient at removing small particles, including common allergens such as dust mites, mold spores, and pollen. This results in cleaner air, reducing the risk of allergy symptoms and respiratory issues.

  2. Enhanced System Performance: Installing a high-quality air filter can help prevent dust and debris from accumulating on your HVAC system’s components. This can lead to improved system performance, energy efficiency, and a longer lifespan for your equipment.

  3. Reduced HVAC Maintenance: A MERV 11 filter’s ability to capture a higher percentage of airborne particles can reduce the need for frequent cleaning or maintenance of your HVAC system.

When to Choose MERV 11 Filtration for Your HVAC System

Determining whether MERV 11 filtration is right for your home or light commercial space depends on several factors:

  1. Respiratory Health and Allergy Concerns: If you or your family members suffer from allergies, asthma, or other respiratory issues, a higher-rated filter like MERV 11 can help alleviate symptoms by effectively removing airborne allergens from your indoor air.

  2. Pets and Dander: If you have pets, MERV 11 filters can significantly reduce pet dander, a common allergen, from circulating in your living spaces.

  3. Air Quality in Your Area: If you live in an area with high levels of outdoor pollutants, such as industrial areas or locations with heavy traffic, upgrading to a higher-rated filter can minimize the infiltration of outdoor contaminants into your indoor spaces.

Installing and Maintaining Your MERV 11 Filter

For optimal performance and indoor air quality, it’s essential to follow proper installation and maintenance procedures for your MERV 11 filter:

  1. Professional Installation: Our skilled technicians can ensure that your MERV 11 filter is correctly installed and integrated into your existing HVAC system. Proper installation is vital to maximize the filter’s efficiency in capturing airborne particles.

  2. Filter Replacement: Like all HVAC filters, MERV 11 filters will eventually accumulate dirt and become less efficient at capturing particles. To ensure optimal air quality and system performance, it’s essential to replace your filter regularly, typically every 3-6 months. Our professionals can provide you with a replacement schedule tailored to your specific circumstances and filter type.

  3. Regular Maintenance: Even with a high-quality filter in place, it’s crucial to schedule regular maintenance for your HVAC system. This includes cleaning and inspecting system components to ensure optimal performance and prevent potential issues.


Investing in a MERV 11 filtration system for your HVAC system is a powerful way to enhance your indoor air quality and create a healthier environment in your residential, light commercial, or custom home spaces. By understanding MERV ratings and the benefits of high-quality air filters, you can make informed decisions about your HVAC system and improve your overall well-being.
