5 Tips on How to Choose the Right Furnace Filter

Posted November 10, 2023 by in Home

When maintaining a comfortable and healthy indoor environment, choosing the right furnace filter is essential. A quality filter improves air quality, reduces energy usage, and extends the life of your heating system. With numerous options available, choosing the right filter can be daunting. To help, we offer the following tips on furnace filter selection.

Learn About MERV Ratings

The MERV or minimum efficiency reporting value rating is a way to evaluate the effectiveness of furnace filters. MERV ratings typically range from 1 to 20, with higher ratings indicating better performance. Higher-rated filters capture smaller particles and provide additional air purification, but the extra air resistance may strain your heating system. For most homes, a furnace filter with a MERV rating between 8 and 12 will maintain air quality without putting undue pressure on your heater.

Consider Filter Materials

Furnace filters are made of various materials, each with unique characteristics. The most common types of filters used during furnace installation weiser id are:

· Fiberglass filters. An affordable but basic option, a fiberglass furnace filter is designed to capture the largest particles.

· Pleated filters. These furnace filters have more surface area, which allows them to grab smaller particles. Pleated filters strike a good balance between performance and cost, and they work well in most homes.

· Washable filters. Because they can be reused, washable filters are a cost-effective choice. However, they aren’t the best at capturing small particles like dust and pet dander.

· High-efficiency filters. These options, including HEPA filters, offer superior purification by gathering the smallest particles. High-efficiency furnace filters are a good choice for those with asthma or allergies, and they require frequent replacement because of their density.

When choosing a furnace filter, consider your household’s budget, your needs, and each filter’s maintenance and replacement requirements.

Find the Right Size Air Filter

One of the most important steps when choosing a furnace filter is ensuring that it’s the right size for your system. Air filters come in several sizes, and picking the wrong one will lead to inadequate air filtration and reduced system efficiency.

To find the right size, check the system manual or look at the old filter. If your heating system uses a non-standard filter size, you may have to order filters with precise dimensions. Accurate filter measurement will prevent fitment issues.

Balance Airflow and Filtration

Optimal airflow is crucial for efficient system operation. While higher MERV ratings equal better filtration, they also restrict airflow, making systems work harder, reducing performance, and increasing energy usage. To balance airflow and filtration, choose a furnace filter with the right MERV rating for your needs.

Follow a Maintenance Schedule

Replacing the air filter regularly will ensure continued efficiency. Depending on filter type, household size, pet presence, and other factors, most families should replace or clean their furnace filters every 30 to 90 days. Consider setting a calendar reminder, as a clogged or dirty filter affects air quality and system efficiency.

Follow These Tips to Find the Right Furnace Filter

Selecting the right air filter helps families maintain a comfortable, healthy, and warm indoor environment. Learning about MERV ratings, choosing the right material and size, balancing airflow and filtration, and changing filters regularly are all essential tips that will help keep your system running smoothly and energy costs under control.
