The central heating and cooling equipment in your Long Island home plays two key roles: (1) it keeps your household at a comfortable temperature and (2) circulates air throughout your indoor environment. Therefore, the air filter in this equipment acts as your home’s first line of defense against offensive airborne contaminants like mold spores and dust. When it comes to choosing a filter for that system, there are a number of options from which to choose. However, selecting a higher-efficiency air filter may be the best choice for your home.
What are higher-efficiency air filters?
Air filters have a Minimum Efficiency Rating Value (MERV) rating that reflects their capability to capture prevalent airborne particulates like dirt, pollen, and mold spores. The MERV scale runs one to 20; the higher the number, the more capable an air filter is at capturing smaller particles. Medium- to higher-efficiency air filters are rated at a MERV 13 and above. They are often have a pleated design covering a larger area. These filters are able to trap most of the particles in your indoor air environment, ensuring a cleaner HVAC system and healthier air quality.
Filters with a lower MERV rating of one to 4 are single-paned. They are only capable of stopping larger particles and, while it will keep larger debris out of your HVAC system, will have little impact on your air quality.
Before purchasing a higher-efficiency air filter, it is advisable to speak with a qualified HVAC technician to determine the filter’s compatibility with your central HVAC equipment. This is because higher-efficiency air filters have a thicker and more tightly woven design that can impede the airflow of your HVAC system as the filter becomes clogged. If your system is not compatible, or filters are not regularly replaced, your equipment will be forced to work harder to push airflow through the filter. This can lead to higher energy bills and burnout of key equipment parts, requiring premature repair or replacement.
