When it comes to air filters, the MERV rating is an essential factor to consider. MERV stands for Minimum Efficiency Reporting Value and it is used to measure the effectiveness of air filters in capturing airborne particles. A filter with a MERV 11 rating is capable of blocking at least 65% to 79% of airborne particulates in the 1.0 to 3.0 micron size range, making it an ideal choice for homes located in a contaminated area, or those with pets or family members with allergies. It's important to note that a filter's MERV rating is its minimum performance, and selecting the right filter for your home will ensure that your air conditioning system works optimally.
MERV 11 air filters are applicable to most commercial buildings, residences, industrial workplaces, and paint booths. For homes with pets or family members with allergies, a MERV 11 filter is the best option. Consider replacing it with a filter with a higher MERV score if you experience frequent allergic reactions. The higher the MERV rating, the more airborne pollutants the air filter can remove before entering your home.
How often you should change your home air filter depends on the type of filter, its thickness, the MERV rating, and some special conditions. Generally speaking, air filters with a MERV 11 rating or higher usually take three to six months before being replaced. For example, the most demanding structures, such as hospitals, clean rooms, and nuclear power plants, often require air filters with a MERV rating of 16 to 20. On the other hand, a MERV filter 13 is capable of capturing all the particles that 11 can capture, in addition to bacteria and viruses.
If you don't have a pet or don't have any health problems that affect your breathing, you can get by with a lower-quality MERV 8 filter. It's essential to follow the manufacturer's recommendations on maintenance and replacement. All air filters require regular cleaning and filter replacement to work properly. Filter King offers a simple subscription service for the MERV 11 air filter, so you never forget to change them.
Before deciding on a MERV rating, check your oven's manual or information stickers to see what your maximum MERV rating is. The average efficiency range of the MERV 5-10 will probably require filter changes in around two to three months. To obtain a high MERV rating and a greater thickness, these filters easily require only two filter changes per year. Make sure you follow the manufacturer's recommendations for maintenance and replacement for optimal performance.
