Why Filters are Essential for Air Conditioning Systems

The filters used in your home's heating and cooling system have an important job to do: they trap dust, pollen, pet dander and other small particles from the air you and your family breathe. This prevents them from being recirculated throughout the house. The air from the HVAC system passes through the air cleaner, which is designed to remove particles and contaminants such as dust, mold, pet dander and fungal spores. The mesh of the filter traps these materials while still allowing air to pass through.

If you don't change the air filter as often as you should, it can become clogged with dirt and debris, making it harder for air to pass through. This can lead to poor indoor air quality and damage to your HVAC system. To ensure that your HVAC system is working properly, it is important to regularly change or clean the filter. HEPA filters are a type of filter that can provide a higher level of filtration than standard filters.

However, they are not suitable for all HVAC systems due to size and airflow restrictions. If you want to use a HEPA filter in your home, modifications will need to be made by an HVAC contractor. Reusable area filters are another option. These filters are washable and can be used again and again.

However, they tend to have a lower MERV rating (between one and four) which makes them more prone to mold and mildew buildup. Most central air conditioning units have two or more filters that clean the air and ensure good air quality as your unit circulates between indoor and outdoor air. The filter is an important part of the air conditioner as it prevents dirt from entering the system and causing significant damage. Accordion filters are designed with pleats that provide more surface space for air to pass through, while still trapping particles and contaminants.

This helps reduce total airflow resistance, which is beneficial for your HVAC system. If you have pets or allergies (or both), a filter with as little particulate filtration as possible may pay off the potential side effects of your HVAC system so you can breathe better. It is important to regularly change or clean your filter in order to keep your HVAC system running efficiently and effectively. Modern technology has made it easier than ever to keep track of when it's time to change or clean your filter. Smartphone reminders can alert you when it's time for a filter change, or if your filter is dirty before the scheduled change time.
