What is an Air Filter and Why Is It Important?

Air filters are an essential component of any HVAC system, designed to remove airborne particles such as dust, pollen, mold spores, and other allergens from the air that passes through it. This helps to improve the air quality in your home and protect you and your family from potential health problems.

How Does an Air Filter Work?

Air filters are usually made up of paper or fiberglass material that is intended to capture particles as they pass through. As air moves through the filter, these particles become trapped in the fibers of the filter, preventing them from entering your home’s air supply. The more effective the filter is at trapping these particles, the better job it will do at improving air quality.

Types of Air Filters

There are many different types of air filters available on the market today. The most common type is a disposable fiberglass filter which should be changed every 30 days. There are also pleated filters which can last up to 90 days before needing replacement. If you have allergies or asthma, you may want to consider using a high-efficiency particulate air (HEPA) filter which can trap up to 99.97% of airborne particles.

Benefits of Using an Air Filter

Using an air filter has many benefits including reducing dust and other allergens in your home’s atmosphere; this can help alleviate allergy and asthma symptoms for those who suffer from them. Additionally, using an air filter can help reduce dirt and dust buildup on furniture and other surfaces in your house; this will also improve energy efficiency by reducing dirt accumulation on HVAC system components.

How Often Should You Change Your Air Filter?

The frequency with which you should change your furnace filter depends on several factors including type used as well as level of contaminants present in the home's atmosphere. Generally speaking, disposable fiberglass filters should be changed every 30 days while pleated ones can last up to 90 days before needing replacement; if you have pets or live in an area with high levels of pollutants then changing more frequently may be necessary.

Conclusion

An air filter is an essential part of any HVAC system, helping to remove airborne particles from the home's atmosphere; there are many different types available and the frequency with which they should be changed depends on several factors. Using one provides numerous benefits including improved air quality, reduced buildup on furniture and other surfaces, and improved energy efficiency.
