The MERV rating of an air filter is a measure of its efficiency. It refers to the minimum number of times that air needs to pass through a filter in order to remove a specific percentage of its contaminants. The higher the MERV rating of a filter, the more effective it is at trapping particles, dust, pollen, bacteria and other contaminants that can cause allergies or infections if not removed from the air.Air filters have become an essential part of household appliances such as air conditioners and HVAC systems. These filters trap microscopic dust and dirt particles in the air and help maintain a clean and fresh indoor environment. But how do you know which filter is best for your home? There are different types of air filters available on the market and each has its own MERV rating. Let’s take a closer look at what each MERV number means and how it can help you find the right filter for your home.
The MERV rating is a scale used to measure the efficiency of a filter. It is a number between 1 and 16 that indicates how many times the air needs to pass through the filter in order to remove a specific percentage of its contaminants. The higher the MERV rating of a filter, the more effective it is at trapping particles, dust, pollen, bacteria and other contaminants that can cause allergies or infections if not removed from the air.The MERV scale was developed by the American Society for Testing and Materials (ASTM) in the 1950s. It has since been adopted by most filter manufacturers and is the standard by which filter efficiency is measured.
MERV 1 filters are designed for low-efficiency use in commercial buildings, offices, and other indoor environments where there is little risk of contaminants. They are not suitable for residential use.MERV 1 filters are typically made of fiberglass or cellulose and are usually fairly large in size. They are often used in HVAC systems to protect large ductwork from contamination.MERV 1 filters are not suitable for use in households. They are not recommended for indoor or outdoor use and should not be used in air conditioning systems.
MERV 2 filters are suitable for moderate indoor environments where there is some risk of contamination. They can be used in households, but should not be the only filter in the HVAC system.MERV 2 filters are often made of polyester or fiberglass and are smaller than MERV 1 filters. They are usually installed in the HVAC ductwork and are used to protect the HVAC system from contamination.
