In order to understand whether MERV filters remove VOCs, it is essential to comprehend the MERV rating system. MERV stands for Minimum Efficiency Reporting Value and is a system used to compare the performance of various air purifying filters on the market. The higher the MERV rating, the more small, harmful particles will be eliminated. However, it is important to note that particulate filters do not remove volatile organic compounds (VOCs) or ozone.
In order to effectively remove VOCs and odors, an activated carbon filter must be used in addition to a particulate filter. Activated carbon filters are not covered by ASHRAE tests, but they are essential for eliminating VOCs and odors. Therefore, when selecting an air filtration system, it is important to make sure that it includes an activated carbon filter in addition to a particulate filter with a high MERV rating. HEPA filter air purifiers are the most efficient at recycling dirty and stale indoor air to make it fresh and healthy.
They are able to capture or remove particles from 0.3 to 1 micron, which is why they are often used in residential ovens, window air conditioning units, and pre-filtered commercial buildings. In addition, HEPA filters can help improve air quality when connected to the ventilation system; however, they won't provide the best results when used alone. The SARS-CoV-2 particle is only 0.1 micrometers in size, but it clings to the larger particles (0.3 micrometers) trapped by the MERV 13 filter. This demonstrates why it is important to opt for a filter with a higher MERV rating if any of these things concern you.
In general, the higher the MERV rating, the more effective the filter will be at stopping the smallest particles. It is also important to remember that if you don't change the filter as recommended, it will become too clogged and won't properly purify your indoor air like you would with a new filter. Overall, understanding both filters and their differences will help you make an informed decision when determining the most appropriate solution for your business. A minimum efficiency information value (MERV) is another way to measure the effectiveness of a filter to stop particles, dust, and contaminants based on a percentage of the time. When selecting an air filtration system for your home or business, it is important to consider both MERV ratings and activated carbon filters in order to ensure that VOCs and odors are effectively removed from your indoor air. A high MERV rating will help capture small particles while an activated carbon filter will help eliminate VOCs and odors from your indoor air.
Additionally, HEPA filters can help improve air quality when connected to a ventilation system; however, they should not be used alone as they are not effective at removing VOCs or odors. It is also important to remember that if you don't change your filter as recommended, it will become too clogged and won't properly purify your indoor air like you would with a new filter.
