MERV 5 to 8 filters are an effective way to control mold spores, hairspray, dust, and other particles from 3 to 10 micrometers in size. This makes them applicable in most commercial buildings, residences, industrial workplaces, and paint booths. Based on these characteristics, a MERV 8 filter is considered superior compared to air filters with a lower MERV rating. But is filtration enough? In many cases, a MERV 8 air filter is more than adequate. However, if you're concerned about outdoor air pollution, have family members with respiratory problems, or pets at home, then opting for a higher MERV rating might be a good idea.
It's important to note that the MERV 5-8 range can only capture air pollutants of 3.0 microns or more. As a result, MERV 8 filters capture medium-sized particles such as aerosols, mold, and dust. For most households, this isn't enough. Harmful viruses and bacteria will continue to circulate around your home, as will smoke and other forms of air pollution. MERV 8 air filters are most often used in residential buildings and can trap around 80% of the particles suspended in the air. Oven filters with this MERV rating are capable of blocking contaminants that are in the 3.0-10 micron range and other larger particles.
They retain dust, mold, pollen, mites, bacteria and pet dander. When buying an air filter, most people wonder if the MERV 8 is a good enough air filter for their homes. It's generally the most affordable air filtering option and, for most homes, it's an adequate way to keep the air healthy. When comparing air filters, the MERV 8 and the MERV 13 usually coincide. Every MERV classification has its own advantages and disadvantages. A MERV 8 filter may be sufficient for some households while others would benefit from a MERV 13 filter.
Minimum Efficiency Report Values (MERV) indicate the ability of a filter to capture larger particles between 0.3 and 10 microns (µm). Raising only three MERV classification levels can be a smart decision to purify the air or a harmful option for the entire air conditioning system considering the air flow capacity of the MERV 8 versus the MERV 11. A MERV 13 filter can capture many harmful pollutants from cigarette smoke to provide more breathable air for non-smokers in the house. If you need better filtration and your air conditioning system can handle it, the MERV 13 may be a better option. It may seem that they are almost the same but the MERV 8 and MERV 11 air filters have some clear differences. MERV 11 air filters are a bit more expensive than a standard filter but it's usually worth paying a few more dollars per filter to increase efficiency.
Since the MERV classification system is standard it makes it easier to compare filters with different ratings. If someone has an allergy or respiratory problem choose a MERV 11 air filter or even a MERV 13 air filter. Generally speaking anything under a MERV 13 air filter should allow for very efficient air purification in the home without affecting airflow. When choosing between MERV 8 and MERV 13 filters you must consider what you want to be filtered from the air and why. If you're concerned about the effects of inhaling fine air particles that's another reason to choose a MERV 11 air filter over a MERV 8 air filter. For some time now the MERV 8 and MERV 11 filters have been competing for the best rating in existence so why do we specifically suggest a MERV 13? Your home's air conditioning system ultimately determines which one you can use. According to the EPA, MERV 8 filters can capture up to 70% of particles between 3 and 10 microns and up to 20% of between 1 and 3 microns. Therefore, they are usually not suitable for people with allergies, asthma, and other health or respiratory problems.
If there are no pets, people with health problems in the home or there is excessive outdoor pollution then a MERV 8 is probably sufficient. As an expert in SEO optimization I recommend considering all factors before deciding which type of filter is best for your home. The benefits of using a MERV 8, as well as higher rated filters such as MERV 11, should be weighed against your specific needs when it comes to purifying your indoor environment. The cost of each type of filter should also be taken into account when making your decision. Ultimately it's up to you to decide which type of filter will provide you with clean indoor air while still being within your budget.<.
