It's Time to Swap Out Your 20x30x1 Air Filter: 5 Indicators

If you have a HVAC system, then you know that the air filter is one of its most important components. It helps keep the air in your home clean and free from dust, allergens, and other particles. But like all parts of your system, it needs to be changed regularly. Here are five signs that it's time to switch out your 20x30x1 air filter:

1. Heightened Allergy Symptoms

If you suffer from allergies, then you may observe an increase in symptoms when the air filter isn't changed frequently. When the filter becomes clogged with dirt and debris, it can't do its job correctly and the air quality in your home suffers. If you detect an intensification of allergy symptoms, then it may be time to replace your air filter.

2. Unusual Aromas

A dirty air filter can cause strange smells to linger in your house. This is because the filter isn't able to trap odors like smoke or pet dander as effectively as a clean one would be able to do. If you notice any peculiar or unpleasant aromas coming from your HVAC system, then it's likely time for a new filter.

3. Poor Airflow

When the air filter becomes blocked with dirt and debris, it can restrict airflow through the system. This can lead to a decrease in performance and efficiency which could result in an increase in energy bills if left unchecked for too long. If you notice poor airflow coming from your vents, then it's probably time for a new filter.

4. Visible Dirt or Debris

If you can see dirt or debris on the air filter, then it's definitely time to replace it. A clogged filter won't be able to catch any more particles, so it's best to switch it out for a new one. This will help keep your air clean and free from contaminants.

5. Filter Age

Even if you don't notice any of the other signs, it's still important to check your air filter regularly. Most filters should be changed every three months, but this can vary depending on the type of filter and the environment in your home. It's best to consult your HVAC system's manual to determine the recommended replacement schedule.
