Your HVAC system plays a pivotal role in maintaining a comfortable and energy-efficient home. For it to do its job effectively, every part of the system must be in good condition. One component that takes on a significant responsibility is the air filter. Here’s an overview of its importance.
Understanding Air Filters
Air filters are porous screens commonly made up of either spun fiberglass materials or pleated cloth. A relatively hard cardboard frame holds these materials tightly together, ensuring that air can only pass through the filter and not around it. Depending on the type of filter you have, a certain number of particulates will be removed from the air that is circulating through your system.
The Role of Air Filters in HVAC Efficiency
Improved Airflow
The primary function of air filters is to trap and hold particles present in the air. This could be anything including dust, dust mites, dander from pets, mold spores, microorganisms, chemical pollutants, and more.
If you have a flawed filter that allows these particles to sneak inside your system, they’ll accumulate inside ducts and vents, restricting airflow. This will force your system to work harder to pull or push air to where it is needed.
Maintaining Energy Efficiency
When a system works harder to circulate air, it will consume a lot of energy. This mainly happens when air filters are dirty and allow a lot of particles through.
Such a system will have a reduced heating or cooling capacity and potentially overheat. On the other hand, if you have an efficient air filter, your HVAC system won’t struggle to do its job and will consume less energy.
Preventing Damage
Dust particles, microorganisms, and debris can wreak havoc on the internal components of an HVAC system. For instance, when particles accumulate on the fan motor bearing, they can hinder spinning, causing increased wear and tear. Also, when dust clogs the evaporator coil, it can prevent it from absorbing or releasing heat.
Increased Lifespan
The less time a system runs under stress, the better and longer it will function. Also, the reduced need for repair and replacements will ensure it functions as designed and installed.
Health Benefits
Air filters remove microscopic particles that can adversely affect your health. Chances of falling sick, having an allergic reaction, or having an asthma attack will significantly go down when you change your filter regularly.
Moreover, you will experience greater comfort due to the improved airflow and cleaner air facilitated by the HVAC filters. This translates to better sleep, higher productivity, and a generally improved quality of life.
Common Types of Air Filters Used in Residential HVAC Systems
1. Fiberglass Filters
Fiberglass filters are made up of glass strands spun together and reinforced by hard cardboard or a metal grate. They are the most common type of filters found in households because of their affordability.
Fiberglass filters can only trap particles like dust and carpet fibers, which range from 3.0 to 10.0 microns in size. They would be suitable for you if you live in an area with low levels of pollutants in the air and have no allergy or respiratory issues.
2. Pleated Filters
The most immediate upgrade from fiberglass filters is pleated filters. They are made from cotton fabric or polyester arranged in folds to increase surface area for air filtration. Depending on the rating, pleated fibers can trap all contaminants, with the best capturing even viruses, pollution, and smoke.
3. Electrostatic Filters
You can also buy filters that are made up of a series of metal plates that are charged with electricity. These types are often washable and reusable and are effective in capturing pet dander, pollen, and even microorganisms.
They work by creating a static charge that works like a magnet that pulls and trap pollutants on the metal plates. They may contain another type of filter as well to enhance efficiency.
4. HEPA Filters
These are the most efficient air filters you can get for your home. They can remove up to 99.97% of all particles present in the air, making them ideal for people living in areas with extremely high levels of pollutants.
However, it’s important to note that you can’t just buy a HEPA filter and install it on any type of HVAC system. They can restrict airflow, making your system work harder than it should to circulate air. For this reason, confirm that your HVAC equipment is specifically designed to operate with HEPA filters.
