Choosing the Right Air Filters: A Guide from Garrett Heating and Cooling Experts Nov 20, 2025

When it comes to maintaining a comfortable and healthy home environment, choosing the right air filter for your HVAC system is crucial. At Garrett Heating and Cooling, we understand the importance of this decision, and we're here to guide you through the process of selecting the best air filter for your needs.

The first step in choosing an air filter is understanding the purpose of air filters in your HVAC system. Air filters play a critical role in trapping dust, pollen, pet dander, and other airborne particles, improving indoor air quality, and protecting your HVAC system from dust and debris buildup. This not only helps in maintaining a clean and healthy environment but also ensures that your system runs efficiently.

A key term often encountered in this selection process is the Minimum Efficiency Reporting Value or MERV rating. The MERV rating measures an air filter's ability to capture particles of different sizes, with higher ratings indicating better filtration performance. Understanding MERV ratings will help you choose the right filter. For instance, a filter with a MERV rating between 8 and 13 is ideal for most residential households, as it effectively traps common airborne contaminants without straining your HVAC system.

While MERV ratings are important, they are not the only factor to consider. You also need to take into account the specific needs of your home. If allergies are a concern for your family, consider opting for a higher MERV-rated filter or one labeled as HEPA, which stands for High-Efficiency Particulate Air. HEPA filters are designed to capture 99.97% of particles that are 0.3 microns or larger, making them an excellent choice for homes with allergy sufferers.

It's essential to balance filtration efficiency and airflow when selecting an air filter. High-efficiency filters can restrict airflow if not compatible with your HVAC system, potentially leading to increased energy costs and reduced system lifespan. The technicians at Garrett Heating and Cooling are available to evaluate your system’s specifications to ensure that you choose a filter that maintains proper air flow, optimizing performance.

Consider the longevity and cost of the filter as well. Typically, air filters need replacement every one to three months, depending on usage and filter type. Although some high-performance filters can be more expensive upfront, they might offer longer service intervals and better performance in the long run, potentially saving you money and effort over time.

Our team at Garrett Heating and Cooling is equipped with the expertise to assist you in making the best choice for your home. We consider all these variables, including the size and type of your system, your indoor air quality needs, and your budget constraints to recommend the perfect air filter tailored just for you.

In conclusion, selecting the right air filter involves understanding MERV ratings, considering specific household needs, balancing efficiency with airflow, and being mindful of cost and longevity. Investing time in choosing the right air filter can greatly impact your home’s comfort, air quality, and your HVAC system's efficiency.
