Unlike traditional HVAC systems that recirculate indoor air, an ERV unit pulls fresh air from the outside and exchanges it with the stale air inside. This helps maintain a healthy indoor environment by introducing fresh outdoor air and removing pollutants. The filtered air is then brought inside, helping to regulate your home's air quality without the need for recirculation.

 

By replacing the filter, you're ensuring that the fresh air being drawn into your home is as clean and healthy as possible, which is especially important for those sensitive to allergens and other airborne particles.

 

Replacing the filter regularly will keep your ERV unit working efficiently and help maintain optimal air quality in your home.

 

MERV 8 vs. MERV 13 Filters

 

When shopping for furnace filters, you’ll often come across options ranging from MERV 8 to MERV 13. While both provide better air quality than basic fiberglass filters, the difference in price can make you wonder if upgrading from MERV 8 to MERV 13 is worth it.

 

What Are MERV Ratings?

 

MERV (Minimum Efficiency Reporting Value) measures how effectively a filter captures particles. MERV ratings range from 1 to 20, with higher ratings filtering smaller particles. MERV 8 filters trap particles larger than 3 micrometers, while MERV 13 filters catch particles as small as 1 micrometer.

 

The Impact of a Small Difference

 

Though MERV 8 and MERV 13 differ by only 2 micrometers, this small change can significantly affect air quality. MERV 8 is sufficient for trapping common dust and pollen, but MERV 13 can capture smaller particles like pet dander, smoke, and bacteria, making it ideal for homes needing higher air quality.

 

Benefits of MERV 8 vs. MERV 13

 

MERV 8: Great for average homes. It traps dust, pollen, and larger allergens, offering solid protection without a high cost.

 

MERV 13: Best for those who need superior air filtration. It’s highly effective at trapping pet dander, mold spores, smoke, and bacteria—helping to improve air quality, reduce allergy symptoms, and protect respiratory health.

 

 

When to Upgrade to MERV 13

​

Allergies: If you suffer from allergies, MERV 13 can help reduce symptoms by capturing smaller allergens.

Pet Owners: MERV 13 is ideal for homes with pets, as it traps pet dander more effectively.

Pollution: For those living near smog, factories, or wildfires, MERV 13 ensures cleaner air indoors.

​

While MERV 8 filters work well for many homes, upgrading to MERV 13 can have a noticeable impact on air quality, especially for those with allergies or respiratory concerns. The small price difference can lead to significant health benefits, making MERV 13 a worthwhile investment for cleaner air.
