How MERV Ratings Impact Indoor Air Quality

What Is MERV Rating? - Tap here to discover insights into how MERV ratings affect your indoor air quality at home and the performance of your HVAC systems.

How MERV Ratings Impact Indoor Air Quality

The Impact Of MERV Ratings

Are MERV ratings familiar to you? These figures, which stand for Minimum Efficiency Reporting Values, are essential for evaluating the quality of the air inside your home. 

Better filtration results from higher numbers since they may collect even tiny particles like smoke, pollen, and dust. However, how would you choose which is best for you? Let's read more to discover a lot about the benefits of MERV Ratings.

Key Takeaways

  • The effectiveness of air filters is determined by MERV ratings. Superior filtration of airborne particles corresponds to higher ratings.

  • MERV-rated filters capture tiny particles like smoke and bacteria resulting in improving the quality of air.

  • Filters help lessen the symptoms of allergies and asthma by clearing the air of toxins.

  • Poor air quality could result from HVAC system airflow restrictions caused by incorrect MERV filters.

  • To find the optimal MERV rating, you need to consider the cost of filters, the effectiveness of your HVAC system, and the quality of the air.

Learning about MERV Ratings

Learning the meaning and purpose of MERV ratings is necessary in order to be aware of them. A measurement scale called the Minimum Efficiency Reporting Value is used to assess an air filter's effectiveness. This scale, which goes from 1 to 20, indicates better filtration.

Selecting the appropriate MERV grade depends on the intended use and particular requirements. Hospitals and general surgery settings are examples of commercial MERV applications that often choose ratings in the range of 13 to 16. On the other hand, residential use normally requires 7–12 levels.

Effect On Indoor Air Quality

Pet dander, pollen, and dust mites are among the allergens that MERV filters can capture. This can lessen allergy symptoms by keeping allergens from dispersing throughout the air in your home.

Furthermore, MERV's function extends beyond allergy management. Filters with the correct ratings are beneficial for asthmatics because they aid in eliminating smoke and hazardous air. Controlling these irritants can help reduce the chance of developing signs of breathing issues because they can cause asthma episodes.

How MERV Ratings Affect Airborne Particles

There are different MERV levels designed to catch various sizes of airborne particles. For instance, MERV 1-4 is used to evaluate larger particles like dust and pollen, whereas MERV 13–16 is used to rate smaller particles like bacteria or tobacco smoke.

Consider the particles that are most dangerous to you when choosing a filter. Whether you smoke or have a pollen allergy, there is a MERV rating that is perfectly suitable for you. 

The Performance of MERV Rating and HVACs

The effectiveness of your HVAC system is also influenced by the MERV rating of the air filter you use. Finer filtering is linked to higher ratings, but the situation is more complicated than that because it can block airflow, increasing the strain on your HVAC system and raising usage and expenses for electricity.

On the other hand, filters with lower MERV values allow for more airflow. Smaller particles might escape but it would lower energy usage and improve air quality. So it's really important to find a balance between preserving the best possible air quality and not overworking your HVAC system.

Deciding on the Optimal MERV Rating

When picking a MERV rating for your living area, you must find the correct balance between energy economy, air quality, health considerations, and filter expenses.

When your loved ones have breathing issues, they may benefit from higher MERV ratings. These filters help to improve the quality of air and may also alleviate the symptoms of some diseases by capturing small particles.

However, filtration costs are not to be disregarded. Stronger MERV ratings are typically associated with more expensive filters. Additionally, the need for frequent replacement results in expense accumulation.

Frequently Asked Questions

How Much Do MERV-Rated Filters Cost?

Despite their higher initial cost, high MERV filters eventually save money due to their longer lifespan and increased energy efficiency. In turn, a first investment could bring large long-term financial rewards.

Can a High MERV Rating Filter Help Reduce Allergens?

Indeed, employing filters with high MERV ratings would greatly minimize allergies in your living areas. They trap allergen sources more efficiently than filters with lower ratings, leading to a noticeable upgrade in indoor air quality.

Do I Need a Professional to Change My MERV-Rated Filter?

Engaging a professional to replace your MERV-rated filter isn't necessary. This task is easily achievable with some DIY skills so no need to hire a professional.

How Often Should I Change My Filters?

You should change your MERV-rated filters every one to three months. Their longevity varies based on usage and air quality. Regular checks help maintain excellent air quality.

Are There Specific Brands That Produce High MERV-Rated Filters?

High MERV-rated filters are produced by several brands. Honeywell and Filterbuy are among these brands, known for their strict adherence to MERV rating standards. These standards ensure the air quality indoors stays optimal, extending filter longevity.
