The HVAC technology assists in creating a comfortable environment through heating and cooling and improving indoor air quality. Smart homes in the US use energy-efficient HVAC systems. The latest development in the field is the ductless mini-split system, which is famous for its flexibility, low energy consumption, and easy installation.

One of the critical components of an HVAC system is the filter. Filters remove contaminants from the air, such as dust, pollen, and pet dander. Depending on the client’s needs, professionals install different types of filters in HVAC systems.

What is an HVAC Filter, and How Does It Work?

An HVAC filter is a device that helps to remove contaminants from the air in your home. It does this by trapping particles of dust, pollen, and other allergens in its fibers. It prevents them from being circulated back into the air by your HVAC system.

MERV ( Minimum Efficiency Reporting Value) is a scale that indicates how well an air filter can remove particles from the air. The rating is derived from a test method developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE)  that is conducted under conditions that simulate everyday residential and commercial activities.

The highest MERV rating is 20, and the lowest is 0. The ratings in between correspond to the filter’s ability to remove different sizes of particles from the air.

Types of HVAC Filters

1) Fiberglass Disposable Filters

The least expensive option, these filters, are designed to be replaced every 30-60 days. Fiberglass disposable filters are the least expensive option and are designed to be replaced every 30-60 days. These filters are made of fiberglass strands woven together and can trap large particles like dust, pollen, and pet dander.

2) Pleated Disposable Filters

These are synthetic media and can be used for either furnace or air conditioner systems. Pleated disposable filters are a good choice for people with allergies or other respiratory conditions because they can remove smaller particles from the air. They are also more efficient than fiberglass filters and can last up to three months.

3) UV Light Filters

These filters are great for purifying the air in your home and killing bacteria and viruses. They are also effective at reducing allergens in the air. However, they can be expensive to purchase and maintain.

If you have allergies or are concerned about the air quality in your home, then a UV light filter may be the best option.

4) Electrostatic Filters

They create static electricity, which attracts dust and other particles to the filter. These filters are often washable, making them a more economical option in the long run. They come with a carbon filter to remove odors.
