When it comes to air filters, it's essential to take into account the quality of the materials used and the filter's efficiency. High-end air filters are usually made of superior materials, such as fiberglass, which is a porous material that can capture more dust and pollen than other materials like cardboard or paper. Fiberglass is also resistant to moisture and doesn't tear as easily as other materials, making it more durable and requiring less maintenance. If you suffer from allergies or asthma, it may be worth spending more money on an air filter that eliminates allergens from the air to help reduce symptoms and, at the same time, stop dust from entering your lungs when you inhale.
A top-notch air filter that costs a bit more can prevent dust and other contaminants from entering the lungs and, at the same time, reduce the amount of allergens in the home. Inexpensive air filters may have fewer pleats (sometimes referred to as creases), which reduces the surface area for trapping pollutants in the air. The advantages of having a high-quality air filter also include cleaner indoor air, lower heating and cooling bills, and a more efficient air conditioning system. When it comes to efficiency, pay attention to the MERV (Minimum Efficiency Reporting Values) classification, which refers to the ability of a filter to filter various particles from the air.
Not only do filters remove dust allergens, mold spores, and other pollutants from the air your family breathes, they also filter out fine dirt particles that can degrade the performance of the air conditioning system itself. The benefits of a good quality air filter include removing dust from the air and preventing allergies, but there are also drawbacks, such as higher costs. You can prevent this from happening by replacing air filters with much larger filters, but this may not always be possible in residential applications.
