The Minimum Efficiency Report Value (MERV) is an industry-standard filter system that rates the overall effectiveness of air filters. A higher MERV rating equals finer filtration, meaning fewer dust particles and other air contaminants can pass through the filter. The air filter plays a fundamental role in trapping dust, dirt, allergens and other particles, preventing them from circulating around the home. Over time, the filter becomes clogged, reducing airflow and reducing boiler efficiency.
Regular replacement of the air filter ensures better indoor air quality and energy efficiency, and extends the life of the boiler. The frequency of filter replacement depends on several factors, such as the type of filter, the level of air pollution, and the manufacturer's recommendations. As a general rule, it is recommended to inspect the filter every 30 days and replace it every 90 days. However, in homes with pets, smokers, or people with allergies, the filter may need to be replaced more often.

A filter that is within the range of 8 to 13 can remove mold spores, lead dust, kitchen dust, flour, hairspray, car fumes, furniture polish, and solder fumes. They can trap between 20 and 85% of all particles. The MERV classification is superior because it is the international standard and makes it easy to compare filters from different brands. Filters with a MERV rating of 8 to 13 are usually high-end filters for domestic use or high-quality commercial filters.
When installing a MERV 8 filter in your home or business, it is important to take certain safety precautions. First and foremost, you should always follow the manufacturer's instructions when installing any type of air filter. Additionally, you should make sure that you are using the correct size filter for your HVAC system. If you are unsure about which size to use, consult a professional HVAC technician for assistance.
The best MERV rating for residential use is one that properly cleans the air in your home without decreasing airflow or overloading your HVAC equipment. While you might automatically think that a higher MERV rating means a better air filter, that's not always the case. The highest MERV rating means that an air filter will capture the most dust, while the lowest rating means that a filter will capture the least amount of dust. In 1987, the American Society of Heating, Refrigerating and Air Conditioning Engineers designed the MERV rating scale to provide a more accurate picture of an air filter's capabilities.
For example, if you have someone in your house who suffers from allergies, you might want to get a higher MERV rating. In addition to selecting an appropriate MERV rating for your needs, it is also important for contractors to take necessary precautions when replacing an air filter for heating, ventilation and air conditioning systems. This includes wearing protective gear such as gloves and safety glasses when handling filters and making sure that all connections are secure before turning on your HVAC system again. One of the best ways to determine which MERV classification you should use is to compare options side by side.
This will help you find an air filter that meets your needs while also ensuring that your HVAC system runs efficiently without any issues.
