How do air filters work?

Air filters are designed to trap particles as they pass through them. The filter will be able to collect these particles on its surface or within its fibers. This helps keep your indoor environment free of pollutants and contaminants.

Why do I need to change my air filter?

Having a clean air filter is important for maintaining good indoor air quality. A dirty or clogged air filter can cause your HVAC system to work harder, resulting in higher energy costs and reduced efficiency. Additionally, it can allow dirt and dust particles to circulate through the vents, which can worsen allergies and increase respiratory problems. It is recommended that you replace your air filter every three months or according to your manufacturer’s instructions.

How do I know what type of filter I need?

There are many types of air filters, so it is important to know the type your HVAC system requires. The most common types of air filters are disposable fiberglass filters, pleated media filters, and carbon activated filters. Different systems may require different sizes and air filter ratings for optimal performance.  It is recommended to install the highest efficiency filter your system can accommodate. 

What are the benefits of air filters?

Air filters can help improve your health by removing pollutants, allergens, and other airborne particles from the indoor environment. Additionally, they can also reduce energy costs by helping to keep your HVAC system running more efficiently and for longer periods of time. This will result in a lower utility bill each month.

A good rule of thumb is to check your filter once per month, and replace it when necessary.

Remember: clean air filters are key to a healthy home!
