TYPES OF HVAC FILTERS<\/strong><\/h2>\n\n\n\n

Do you know which type of HVAC filter your system needs? Below, you will find descriptions of each type of air filter so you can make an informed decision about which one will work best for your household:<\/p>\n\n\n\n

Fiberglass Filters<\/strong><\/h3>\n\n\n\n

At the very basic level of HVAC filters are the disposable fiberglass filters. These are the most commonly used filters due to their affordability. They operate by trapping large dust particles, thus preventing them from circulating in your living space. However, they are not very effective at capturing smaller particles like pollen and pet dander.<\/p>\n\n\n\n

Pleated Filters<\/strong><\/h3>\n\n\n\n

Pleated filters, on the other hand, offer improved filtration efficiency compared to fiberglass filters. Their folded design provides a larger surface area for trapping airborne particles, both big and small. If you\u2019re looking for a balance between cost and efficiency within your HVAC systems, pleated air filters would be an excellent choice.<\/p>\n\n\n\n

HEPA Filters<\/strong><\/h3>\n\n\n\n

HEPA filters, or High-Efficiency Particulate Air filters, are the gold standard for air filtration. These filters can capture up to 99.97% of airborne particles as small as 0.3 microns. They are highly effective in improving indoor air quality and are often used in settings where superior filtration is crucial, such as hospitals.<\/p>\n\n\n\n

Electrostatic Filters<\/strong><\/h3>\n\n\n\n

Electrostatic filters are unique in their operation. They use static electricity to attract and trap particles. One of the major advantages of these filters is that they\u2019re reusable and washable, making them an eco-friendly option for your HVAC system.<\/p>\n\n\n\n

CHANGING HVAC FILTERS<\/strong><\/h2>\n\n\n\n

Picking an HVAC filter for your system is only half the battle \u2014 now, you need to understand when to change<\/em> these filters. Here\u2019s everything you need to know about changing HVAC filters:<\/p>\n\n\n\n

Why Is Filter Replacement Important?<\/strong><\/h3>\n\n\n\n

Changing your air filters is essential for the longevity of your heating and cooling system. Over time, filters become clogged with debris, reducing airflow and forcing your HVAC system to work harder and consume more energy. This increased strain can lead to higher energy bills and potential equipment breakdowns.<\/p>\n\n\n\n

How Often Do Filters Need to Be Changed?<\/strong><\/h3>\n\n\n\n

How often you need to change your HVAC filter depends on several factors, including the type of filter, the level of airborne particles in your environment, and your usage patterns. Generally, it\u2019s recommended to replace standard filters every 1-3 months, while HEPA filters can last up to 6-12 months.<\/p>\n\n\n\n
