When it comes to keeping your HVAC system running smoothly, choosing the right air filter is crucial. With so many options available, it can be overwhelming to figure out which one is best for your home or business. Don’t worry, though—we’re here to help make the decision easier for you.

Understanding MERV Ratings

One of the first things you’ll come across when shopping for air filters is the Minimum Efficiency Reporting Value (MERV) rating. This rating system measures how effectively the filter removes particles from the air. Filters with higher MERV ratings can capture smaller particles, providing better air quality. However, it’s essential to balance efficiency with airflow because filters with very high MERV ratings can restrict airflow, potentially causing strain on your HVAC system.

Consider Your Needs

Before selecting an air filter, consider your specific needs. Do you have allergies or respiratory issues? Are you concerned about pet dander or dust? Understanding your requirements will help you narrow down your options. For those with allergies or sensitivities, a filter with a higher MERV rating may be beneficial. However, if you’re primarily concerned with protecting your HVAC system from larger particles, a lower MERV rating might suffice.

Types of Air Filters

There are several types of air filters available, including fiberglass, pleated, and electrostatic filters. Fiberglass filters are inexpensive but typically have lower MERV ratings and need to be replaced more frequently. Pleated filters offer better filtration and typically have higher MERV ratings. Electrostatic filters use an electric charge to attract and trap particles, making them highly effective.

Our Recommendation

At Dogtown Heating, Air & Plumbing, we recommend pleated air filters with a MERV rating between 8 and 12 for most residential and commercial HVAC systems. These filters strike a balance between filtration efficiency and airflow, providing excellent air quality without putting too much strain on your system. However, we understand that every situation is unique, so feel free to reach out to us for personalized recommendations.
