When it comes to improving indoor air quality, air filters play an essential role. While there are several ways to improve indoor air quality, MERV (Minimum Efficiency Reporting Value) ratings are a popular way to evaluate the effectiveness of air filters. MERV ratings range from 1 to 16, with higher numbers indicating better filtration performance. Many of our clients choose between a MERV 8 and a MERV 13 filter.
Let’s dive into the key differences between MERV 13 and MERV 8 air filters to help you make an informed decision to better your indoor air quality.

MERV 8 Filters: For The Standard Home

MERV 8 filters are one of the most commonly used air filters in residential settings, and the lowest rating that should be used in a residential setting. These filters are slightly less expensive and highly effective for the average home.

Pros of MERV 8 Filters:

• Effective at trapping common allergens like pollen, pet dander, and dust.
• Reasonably priced and easy to find.
• Ideal for homes with basic air quality needs.

Cons of MERV 8 Filters:

• May not be effective at trapping finer particles, such as bacteria, viruses, or smoke.
• Not the best choice for households with severe allergies or respiratory conditions.

MERV 13 Filters: High-Efficiency Filtration

MERV 13 filters are often considered the gold standard when it comes to residential and commercial air filtration. These filters are significantly more effective than MERV 8 filters at trapping a wider range of harmful particles.

Pros of MERV 13 Filters:

• Excellent at capturing very fine particles, including bacteria, viruses, and smoke.
• Great for people with allergies, asthma, or respiratory issues.
• Ideal for homes with pets or newborn babies.

Cons of MERV 13 Filters:

• Higher cost compared to MERV 8 filters
• More demanding on your hvac system which may result in higher energy bills.
• Requires more frequent replacement.

Which One Should You Choose?

When deciding between MERV 13 and MERV 8, the best choice depends on your specific needs:

Choose MERV 8 if:

• You live in an area with relatively good air quality.
• You don’t have any severe respiratory conditions or allergies.
• You want a more affordable option that still provides decent air filtration.
• You need a filter that works well with your HVAC system without putting too much strain on airflow.

Choose MERV 13 if:

• You have severe allergies, asthma, or respiratory issues.
• You live in a high-pollution area or in a home with smokers or pets.
• You are looking to reduce fine particles, bacteria, or viruses in your indoor air. You’re willing to pay a bit more for superior filtration and can accommodate the stress on the system.

Both MERV 13 and MERV 8 filters are excellent choices, depending on your indoor air quality needs. MERV 8 filters are great for general air filtration, providing adequate protection against common allergens. However, if you’re looking for more advanced protection against fine particles like bacteria, viruses, and smoke, a MERV 13 filter might be the better choice.
