When it comes to air filtration, the MERV rating is an essential factor to consider. MERV stands for “Minimum Efficiency Reporting Value” and it is used to measure the capacity of a filter to capture air particles. The higher the MERV rating, the more effective the filter will be at trapping particles from the air. This means that fewer dust particles and other contaminants can pass through the filter.
In addition to controlling the amount of unwanted air particles entering your home, using a higher rated filter with a higher MERV rating can also provide environmental benefits. ASHRAE recommends using MERV 13 filters whenever possible, with MERV-A 13-A or MERV 14 filters being preferred. These filters are able to capture dust, pollen, bacteria and other particles suspended in the air, ensuring a clean and healthy environment. The lower MERV ratings (1-4) are still able to capture some particles such as pollen, dust mites, cockroach debris, sanding dust, spray paint dust and textile fibers. However, they are not as effective at trapping smaller particles such as smoke and bacteria.
Therefore, if you want to ensure that your home is free from these smaller particles, it is best to use a filter with a higher MERV rating. In addition to providing environmental benefits, using a higher rated filter with a higher MERV rating can also help you save money in the long run. These filters must be replaced periodically in order to remain effective, but they are more efficient at trapping particles than lower rated filters. This means that you will not need to replace them as often, which can help you save money on replacement costs. Overall, using a higher rated filter with a higher MERV rating can provide both environmental and financial advantages. Not only will it help keep your home free from unwanted air particles, but it can also help you save money in the long run.
