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 a measure used to determine the effectiveness of air filters. The higher the MERV rating, the more efficient the filter is at trapping particles. A MERV 8 filter is designed to capture particles that are 3-10 microns in size, while a MERV 11 filter can trap particles that are 1-3 microns in size.
This means that a MERV 11 filter is more effective at trapping smaller particles, such as bacteria and viruses. In terms of air quality, a MERV 11 filter is superior to a MERV 8 filter. It can trap more fine particles, such as those that measure 2.5 microns or less. These particles can enter the lungs and bloodstream, so it's important to use a filter with a high enough MERV rating to protect yourself from them. A category 13 MERV filter is recommended for this purpose. When selecting the right heating filter for your home, the MERV air filter rating is a good starting point.
In most homes and commercial buildings, filters with a MERV rating between 8 and 13 will sufficiently filter the air. However, if you have specific concerns about indoor air quality or allergies and asthma, you may want to opt for a higher MERV rating. For example, a MERV 11 filter works better in residential homes with filtration needs than a MERV 8 filter. In addition to all that MERV 8 filters trap, MERV 11 filters can also capture mold spores, lead dust, solder fumes, car fumes, humidifier dust, and other machine fumes and emissions. Using the highest MERV filter in your home would restrict airflow and make it difficult for the HVAC system to function properly, potentially leading to breakdowns and premature system replacement. When selecting an air filter for your home or business, it's important to consider all factors before making a decision.
The MERV rating of your furnace filter should be high on your list of considerations. Choosing between a MERV 8 or a MERV 11 filter depends on several factors such as your specific needs and professional recommendations.
