Minimum Efficiency Report, or MERV, values report a filter's ability to capture larger particles between 0.3 and 10 microns (µm). Regular air filter changes are essential to keeping your system clean and running efficiently, as well as keeping your energy bills under control if you have a boiler, air conditioner, or heat pump in your home in the Ocala area. One of the most common causes of HVAC problems is a clogged air filter, which can cause system failure. Understanding Merv ratings can help you select the best filter for your system. If you're looking for information on what a MERV rating is and how to find the right one, you've come to the right place.
MERV stands for Minimum Efficiency Reporting Value and it's a measure of how effective an air filter is at trapping particles. The higher the MERV rating, the more particles the filter can capture. Most residential air filters have a MERV rating of 7 to 12, while MERV ratings of 13 to 16 are generally found in hospitals and doctor's offices. It's important to note that while a higher MERV rating may seem like it would be better for your system, that's not always the case. Using an air filter with a MERV rating higher than recommended by the manufacturer of your oven or air conditioner may impair its performance.
If your filter's MERV rating is too high, reducing airflow can force your HVAC equipment to the point of damaging it. Finding filters with the right MERV ratings is essential to ensuring that the air is well filtered without overloading the HVAC system. The MERV rating is superior because it is the international standard and makes it easy to compare filters from different brands. For example, a higher MERV rating doesn't always mean that a filter is the best option for your oven. If you have one, make sure you get an oven filter with a MERV rating lower than your system's maximum. Choosing the right MERV rating for your oven filter has a big impact on indoor air quality, your HVAC system, and most importantly, the well-being of your family.
Remember that there are always other solutions available to improve indoor air quality if your system can't handle the MERV ratings you need. MERV 17 to MERV 20 filters are commonly used in operating rooms, cleanrooms, and other settings that require absolute cleanliness.
