The air filter plays a vital role in protecting the performance, integrity, and longevity of your HVAC system. Replacing it regularly promotes proper airflow and safeguards your indoor air quality. Many homeowners choose to take care of this task themselves, but it’s important to select the appropriate filter for your system. Here’s what you should know about your options.

How to Choose an HVAC Air Filter

1. Check the Owner’s Manual

HVAC manufacturers often provide a specific suggestion for filtration. These guidelines indicate the appropriate size, thickness, material, and type suitable for the model. While using the wrong type of filter won’t necessarily damage the HVAC system, it could lead to reduced efficiency and elevated energy bills. It’s best to follow the manufacturer’s recommendation whenever possible to maximize the results.

2. Assess the MERV Rating

All air filters are assigned Minimum Efficiency Reporting Values, or MERVs. This refers to the filter’s ability to effectively trap minuscule particulates, such as bacteria and viruses. Higher ratings indicate a finer-mesh filter that can block more contaminants, helping you to maintain even cleaner indoor air.

However, not all systems are equipped to run efficiently with a finer mesh, so it’s possible they’ll need to work much harder than normal to pull air through it. That could cause your bills to creep up and your system to fail prematurely or require AC repairs more often. Steer clear of the highest-rated filters unless you’re sure your system can use it safely. For the safest results, aim for a MERV rating of 13 and check with an HVAC specialist to better assess your system’s capacity.

3. Choose Washable or Disposable

Both washable and disposable filters are available. Sometimes the manufacturer will provide a suggestion. A washable model will last for years, but it must be cleaned and maintained regularly. Disposable models are designed to be thrown out and replaced every three months.

A clean air filter is only the first step toward home comfort and healthy indoor air quality.
