Is a Merv 8 Air Filter the Right Choice for You?

MERV 8 filters are 90 percent efficient on particles that are 3 to 10 microns in size.


1 to 4 are effective at controlling larger particles, such as sanding dust, spray paint dust, lint and carpet fibers, making them suitable for homes and window air conditioning units. This makes a Merv 8 a superior filtration 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 are concerned about outdoor air pollution, family members with respiratory problems, or pets in the house, then a higher merv rating might be a good idea. Before you buy one, there are a few things you should know. While these filters do a great job of trapping pollen, dust, mold, and other basic air pollutants, they're not ideal if you have allergies or pets. In addition, if you live near smoke pollution, we recommend that you choose a filter with a higher MERV rating.

A Merv 8 air filter is common in homes, commercial buildings, paint booths, and industrial workplaces. These filters are 90% efficient at trapping particles 3 to 10 microns in size. When you change from a cheap fiberglass air filter to a Merv 8 filter, you add a lot more protection. In MERV 8, you are now trapping and trapping the dangerous allergens that cause outbreaks for most allergy sufferers.

Most central home HVAC systems have disposable filters that can be discarded when dirty and replaced with a new one. This comparison table helps highlight the differences between the MERV 8 and MERV 11 filters to make it easier to decide which one works best. It is essential to remember that the MERV rating of an air filter denotes its lowest possible capacity, that is, the minimum percentage of impurities it could effectively filter. So keep that in mind the next time you decide that the price of fiberglass filters should determine if you inhale insect droppings. Most air filters have arrows marked to indicate the direction in which air is supposed to flow through them.

If the filter is heavily soiled with stubborn dirt and grime, then using a coil cleaner can help remove dirt. An air filter replacement is necessary to maintain the health and efficiency of your home's HVAC system. These types of filters are sufficient to trap particles as small as 1 micron, such as car exhaust, pollen, and mold spores. Particles trapped inside the filter can easily come off when handling the filter, so placing the old filter inside a plastic bag can help prevent the spread of filter dust. This means that an oven filter with a lower rating would retain a lower percentage of debris and impurities compared to a filter with a higher rating.

At the heart of an optimally functioning HVAC system is an oven filter with the right MERV rating for you. For residential use, the standard recommendation is to choose an oven filter with a MERV rating between 7 and 13. In conclusion, if you're looking for an effective way to improve your indoor air quality without breaking your budget, then investing in a Merv 8 air filter may be your best option. However, if you're looking for maximum protection from allergens and other pollutants in your home or workplace environment, then it's best to opt for an oven filter with a higher MERV rating.
