Why HVAC Systems Have Air Filters

The filter, although arguably one of the simplest parts of your HVAC system, is also one of the most important. Its primary function is to keep the HVAC system clean and free of damage, but it also plays a part in your indoor air quality.

Here’s why filters are so important and why you shouldn’t go without one.

Protecting Your System

The air brought in by your system is not clean. There are varying levels of dust and other debris, not to mention mold, bacteria, and other allergens. Without an effective removal process, dust and debris will get stuck in your system and cause damage. Therefore, a filter helps to keep your system clean and efficient.

Similarly, a clogged filter will reduce airflow in your system and make it work harder to get to the right temperature. Having a clean filter keeps the dust and debris out of the air you breathe and away from the components of your HVAC system.

Make sure to keep extra filters in stock at home in case you discover yours needs to be changed. If you have a reusable filter, it may be a good idea to keep an extra one on hand to use when you’re cleaning the other.

Protecting You

Air filters also help reduce dust and other particulate matter in the air you breathe. As air cycles through your home, the filter collects the particles that could cause allergic reactions or harm to your health. If you have a clean filter but still feel like your home’s air could be cleaner, you may benefit from a whole-home air purifying system.
