Does an Air Conditioner Filter Air?

Air conditioners cannot purify air, but they do filter dust, pollen, and other allergens. The air filter is part of the entire HVAC system, and most central air conditioning units have two or more filters. These filters clean the air and ensure good air quality as the unit circulates between indoor and outdoor air. An important part of the air conditioner is the filter, which prevents dirt from entering the system and causing significant damage.

Knowing more about the air cleaner will help you make the right choice regarding the unit. Here are some important facts to know about air conditioning filters. Air from the HVAC system passes through the air cleaner, trapping particles and contaminants such as dust, mold, pet dander, and fungal spores. The mesh that is the main namesake of the filter through which air passes becomes denser, thus trapping these materials and not hindering the flow of air.

If you don't change the air filter as often as it should, air can't pass as easily, and more and more details have the possibility of passing through the mesh, damaging indoor air quality. Air conditioners can filter the air thanks to the dust filters inside the unit. They help remove some pollutants, such as pollen and dust, as indoor air passes through them. But when it comes to smaller particles, air conditioning isn't as effective as an air purifier. They're more expensive than fiberglass filters, but they're really good for people who have allergies, as they do a great job of trapping dust and other small particles.

For people with allergies and respiratory diseases, changing the filter frequently is essential to help control seizures and minimize symptoms. Created by the U. S. Army to help with chemical, biological, and radiological filtration processes, it was eventually adapted for appliances such as air conditioners and vacuums. Nylon thread filters can be found in virtually all models of air conditioners, even when the device uses other filtration systems. For best results, change the filter every 45 to 90 days depending on factors such as type of filter you have, size of house, quality of air, number of pets in house, how often you use your unit, and if you or someone in your family has allergies or certain medical conditions.

A clean air filter is essential to your home's indoor air quality, energy efficiency and winter heating. An air filter that is completely clogged by dirt and dust can completely obstruct the flow of air to your home, making your air conditioner work much more.
