Air quality is a major concern for many homeowners, and air filters are an essential part of keeping the air in your home clean and healthy. Air filters trap particles that are invisible to the naked eye, such as dirt, dust, and pollen. Not only do they keep these particles out of your HVAC system, but they also help improve the air quality in your home. An air cleaner is an important component of a healthy HVAC system.
This lightweight barrier prevents dust, allergens, and other debris from entering the air you breathe. It also helps your HVAC system run more efficiently, improving its lifespan and minimizing the need for repairs. However, many people don't change their air filter as often as they should, leading to a number of problems. Understanding the consequences of using a dirty air filter and how often you should replace it can help you save money and improve your comfort and health.
All of the air that heats or cools your home will eventually pass through the HVAC system's air filter. For this reason, it is extremely important that you keep the filters clean in your heating or cooling equipment. The type of filter you use is also important. Standard MERV values range from 1 to 16, with higher numbers indicating better filtration.
A tall MERV filter with a very tight mesh can be too much for some units, resulting in a situation much like a clogged air filter, even right after changing it. HEPA filters are generally considered the gold standard for air filtration, but you'll also want to check how many square feet the filter can cover. As you can imagine, your air filter collects all types of dust, spores, hair, dander and other particles that are pumped through the air conditioning system. Pleated filters trap and retain several grams of dust, preventing it from seeping through the duct and inevitably settling on the surfaces of your home.
Air that would move freely through a clean air filter is trapped behind a dirty one, creating a high energy demand on your HVAC system. Failure to change the air filter as directed means that dust, mold and other particles enter the air and reduce indoor air quality. This can lead to a number of health problems such as asthma attacks and allergies. In addition, dirty filters can cause your HVAC system to work harder than necessary to heat or cool your home, leading to higher energy bills. By understanding how air filters work and how often they should be replaced, you can save money and improve your comfort and health. Cleaning or replacing your air filter regularly is an easy way to ensure that your home's air quality remains high and that your HVAC system runs efficiently.
