What is an air filter?

An air filter is a piece of equipment used in HVAC systems to clean and condition the air that is being circulated throughout your home or business. The filter traps dust, pollen, and other contaminants in the air, preventing them from entering your home or office. While HVAC systems are designed to operate with a certain level of dust and other contaminants in the air, prolonged exposure to high levels of these substances can lead to health problems and other issues.Air filters are a key part of HVAC systems because they help prevent these contaminants from entering your home or office. There are many different types of filters available for different types of HVAC systems. Some filters are designed to trap specific types of contaminants, such as dust, pollen, and pet dander.

How do air filters work?

Air filters trap contaminants in the air. HVAC systems operate using a process called negative pressure. This means that air is drawn from the outside of your home or business through the HVAC system, and into the vents in your house. However, air filters trap contaminants in the air, preventing them from entering your home or business.Air filters trap contaminants in two ways. Airlocks are one way that filters trap contaminants in the air. Airlocks are small holes that are designed to trap larger contaminants, such as dust and pollen. The other way that filters trap contaminants in the air is by using a mesh-like structure.These mesh-like structures are made up of tiny fibers that are designed to trap even smaller contaminants, such as dust and pollen.Air filters trap contaminants in the air by using two different mechanisms. The first is by using a mesh-like structure to trap smaller contaminants, such as dust and pollen. The second is by using airlocks to trap larger contaminants, such as hair and animal dander.Air filters are designed to trap different types of contaminants. Some filters are designed to trap dust, while others are designed to trap pollen. Depending on your specific HVAC system, you may need a filter designed to trap pet dander, mold spores, or any other type of contaminant.

Why do air filters sometimes turn black?

Air filters can turn black for a few reasons. The most common reason for a black filter is that it’s been exposed to a lot of contaminants.
