What do MERV Ratings Mean?

Jul 6, 2021 | Uncategorized

Setting up your HVAC systems is an essential part of completing your home construction. Choosing the right materials, brand, and contractors are all critical in making sure that your home becomes a more comfortable place. HVAC contractors in Hampton, GA, can advise you on the type of filter to use for air filtration.

Minimum Efficiency Reporting Value (MERV) is an important grading system that you must pay attention to when buying or replacing your filter for your AC or heater. A high MERV rating means that fewer air particles will be able to pass through the filter. These particles can measure as tiny as .3 microns! But before you head out too quickly buy the highest possible rating of MERV from an HVAC service, here are some important things to understand.

Hire an Air Conditioning Company

The right company can advise you on which filter with the best MERV rating based on your needs. Typically, household systems can use filters that have 7-12 MERV rating. Pollen, pet dander, spores, and dust mites can be taken care of using these filter grades. On the other hand, a lab or a clinic will require at least a MERV 13 filter to make sure that the area is sterile, along with other sterilization techniques.

Choose the Right Filter for Adequate Airflow and Filtration

Proper airflow is necessary to improve the air quality, and this is why getting the highest MERV rating may not always be the best choice for you. Inquire if your system can handle high airflow resistance, which happens when bigger air particles can’t easily pass through a filter with higher MERV. Make sure you’ll be installing a filter with the right rating for good air exchange and subsequently avoiding damaging your AC or furnace fan.

Change Regularly

Filters must frequently be replaced to maintain proper airflow. Over time, filters get obstructed with dirt and small particles, which increases resistance. Avoid damaging your fan by getting an HVAC service to replace your filters regularly. You must replace all filters with higher ratings every quarter. Using standard-sized filters will save you tons if you have to replace yours frequently.

Consider these tips when you’re hiring an air conditioning company to fix your home cooling and heating system.
