When it comes to air filtration, the MERV rating is an important factor to consider. MERV stands for Minimum Efficiency Reporting Value, and it is a measure of how effective an air filter is at trapping particles. The higher the MERV rating, the more efficient the filter is at trapping particles. The most common ratings are MERV 8 and MERV 11, but there are higher ratings available as well. MERV 11 filters are more efficient than MERV 8 filters because they can capture smaller particles.
They offer additional protection against pet dander, dust mites, automobile emissions, and dust that can damage the lungs. This is a good option for homes with pets or for those looking for even better air quality than the MERV 8 can offer. It's also our most popular type of air filter. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) recommends MERV 13, but this may not be the most efficient option for some residential air conditioning systems. In fact, MERV 11 may even be too restrictive.
It's best to comply with the furnace manufacturer's recommendations or consult an HVAC professional to determine exactly which MERV rating is best for your specific system. Meanwhile, air filters with a MERV 14 rating or higher are designed for commercial air conditioning systems that can withstand the coarser filter material. If you're trying to decide between a MERV 8 air filter and a MERV 11 air filter, here's what you need to know. The higher a filter's MERV rating, the less dust particles and other contaminants can pass through it. The higher the MERV rating, the greater the excess pressure or air resistance exerted by the filter in the air conditioning system. Generally speaking, anything under a MERV 13 air filter should provide very efficient air purification in the home without affecting airflow.
If you install a higher filter than the one you were using, for example, if you switch from MERV 8 to MERV 11, you may be able to control your energy bills. A MERV rating higher than 13 will likely wear out or damage your equipment, and a MERV rating lower than 8 may not effectively remove particulates from your home air. In conclusion, when it comes to choosing an air filter for your home, it's important to consider both your needs and your budget. The best way to determine which type of filter is right for you is to consult an HVAC professional who can assess your specific system and recommend the best option for you. With the right information and guidance, you can make an informed decision about which type of filter will provide you with optimal air quality.
