When Is It Time To Change Your 20x20x1 Air Filter?

Your 20x20x1 air filter is an important part of your home's HVAC system, helping to keep the air inside your house clean and free from contaminants like dust, pollen, and other allergens. But like any other filter, it needs to be changed regularly in order for it to remain effective. Here are some signs that you need to replace your 20x20x1 air filter:

The Filter Looks Dirty

If you can see dirt or debris on the surface of your air filter, then it's time for a replacement. Over time, the filter will become clogged with dirt and debris which reduces its efficiency and allows more contaminants into your home. If you notice a buildup of dirt or debris on the surface of your air filter, then it's time for a change.

You Notice Unpleasant Odors in Your Home

A dirty air filter can cause odors to linger in your house. If you smell something unpleasant in your home, it could be caused by a dirty air filter that isn't trapping odors properly. Replacing the filter can help reduce or eliminate odors in your home.

Your HVAC System Is Noisy

A dirty air filter can cause your HVAC system to run louder than normal. This is because the clogged up particles restrict airflow and make the system work harder than usual. Replacing the old one with a new one can help reduce noise levels and make sure that everything runs smoothly.

Your Energy Bills Are Increasing

If you notice that even though you haven't changed anything about how much energy you use, your bills have been going up, then this could be due to an old, dirty air filter. A clogged up one restricts airflow which makes everything work harder than necessary, resulting in higher energy bills.

You Have Allergy Symptoms

If allergies are an issue for you, then an old, dirty air filter could be making them worse. A clogged up one won't trap allergens such as dust and pollen effectively, allowing them into circulation around your house which aggravates allergy symptoms.
