MERV 8 filters are a great choice for homeowners, as they can pick up particles as small as three microns. On the other hand, Merv 13 filters can pick up particles as small as two microns. This may not seem like much of a difference, but it is important to understand how things work at the molecular level. MERV 8, 11 and 13 air filters may look similar, but there are some significant distinctions between them.
To keep MERV 8 filters running at full capacity, experts recommend changing them every 2-3 months. This is especially important if you use your HVAC system frequently. MERV 11 filters tend to get loaded with trapped debris faster than MERV 8 filters, since their fibers are denser. For maximum efficiency, you should change your MERV 11 filter every 1 to 3 months, depending on the season and the intensity of work of your HVAC system.
All of the particles mentioned in MERV 8, such as pet dander, smoke, smog, and air from coughs and sneezes, are trapped by a MERV 11 filter. If you have children or pets in your home, a MERV 11 filter is essential. It will filter out many of the most common air pollutants and irritants, making it a great choice for allergy sufferers. In addition to all the particles mentioned in MERV 8 and 11, MERV13 captures small viruses and germs because it is very fine.
If a healthy home is a priority for you, a MERV 13 filter is a great option. It's also a good option if you have respiratory problems, such as asthma. A MERV 13 filter is also recommended for homes with the elderly or infants. If none of these variables apply to your home and there is no other reason why you need a higher level of filtration in your home, then a MERV 8 filter is probably the best option for you.
This filter assortment will keep your home's airflow clean enough without overloading your HVAC system. What is a Merv rating? The higher the Merv rating on a filter, the less dust particles and other contaminants can pass through it. You may want to invest in filters with higher Merv ratings if your family suffers from allergies or major respiratory conditions, such as asthma. This rating structure is very similar to the MERV rating and was created by Home Depot for brands supplied through its stores, including Honeywell. If you live in an area with heavy construction, factories, or smog, using a Merv 13 filter will ensure that the air inside your home is not polluted. A wonderful method to keep your home comfortable for you and your four-legged family members is to get an air cleaner with a higher MERV rating.
Although filters are available with Minimum Efficiency Rating Value (MERV) ratings from 1 to 20, most furnace filter suppliers only have filters in the MERV 8-13 range. You should consider both the actual cost of a Merv filter and any additional operating expenses that may result. Now I don't want to alarm you, most likely nothing fatal will happen in your house if you choose a lower MERV filter.
