How an air filter works | ulimate home mechanics guide
Air filters are an important part of any home’s HVAC system. They help to keep the air in your home clean and free of dust, pollen, and other airborne particles. Air filters work by trapping these particles in a mesh or paper filter, preventing them from entering your home’s air supply.
There are several different types of air filters available on the market today. The most common type is the disposable fiberglass filter, which is made from spun glass fibers that trap particles as small as 0.3 microns in size. These filters are relatively inexpensive and easy to replace, but they do not last very long and need to be replaced every few months.
Another type of air filter is the pleated filter, which is made from a combination of paper and synthetic fibers that can trap particles as small as 0.3 microns in size. These filters are more expensive than fiberglass filters but last longer and can be washed and reused multiple times before needing to be replaced.
The third type of air filter is the HEPA (High Efficiency Particulate Air) filter, which is designed to trap particles as small as 0.3 microns in size with 99% efficiency. These filters are more expensive than other types of air filters but offer superior filtration performance and can last up to one year before needing to be replaced.
The benefits of using an air filter in your home include improved indoor air quality, reduced allergens, improved energy efficiency, and better overall health for you and your family members who suffer from allergies or asthma. By trapping airborne particles such as dust mites, pollen, pet dander, mold spores, smoke particles, bacteria, viruses, and other pollutants before they enter your home’s air supply you can reduce the amount of these contaminants that you breathe in on a daily basis. This can help reduce allergy symptoms such as sneezing or coughing as well as improve overall respiratory health for those who suffer from asthma or other respiratory conditions. Additionally, using an air filter can help improve energy efficiency by reducing the amount of dust that accumulates on heating/cooling coils which reduces their efficiency over time if not cleaned regularly.
