Cleaning Your AC Air Filter and Why It’s Important

When was the last time you inspected your air conditioner filter? As a rule of thumb, you should check it every month and take the appropriate steps when it is dirty. We’ll share details about the multiple types of AC filters, why they need regular care and detailed instructions on how to wash reusable filters properly.

Types of AC Filters

Your filter design impacts indoor air quality, how effectively air flows and whether you should clean or replace it when it becomes old. Here’s a summary of some popular options:

• Disposable filters are commonly made of fiberglass with a paper frame. These filters are meant for short-term use and need to be replaced every one to three months. They are typically low cost and simple to replace but not as environmentally friendly as they need to be thrown out.
• Reusable filters have stronger frame materials like aluminum or plastic. These filters can be cleaned and reused multiple times, and can last many years if cared for correctly. They are more environmentally friendly and affordable over time. On the other hand, cleaning them takes additional time and effort than simply changing a disposable model.
• Electrostatic filters employ static electricity to trap pollutants efficiently while maintaining airflow. These can be designed to either be disposable or reusable. Reusable electrostatic filters need regular washing to maintain their effectiveness.
• HEPA filters, or high-efficiency particulate air filters, are the best filters of all, capturing 99.97% of airborne particles down to 0.3 microns. Most HEPA filters are single use, but they remain effective for up to an entire year before having to be replaced. While they deliver exceptional filtration, they are higher priced and may not be compatible with all HVAC systems.

Why Should You Clean or Change the AC Filter? 4 Reasons Why

It’s an easy chore to overlook, but rinsing or changing your AC filter is important for several reasons:

1. Enhanced air quality: A clean filter is more effective at trapping dust, pollen, pet dander and other contaminants, keeping your indoor air purer and safer. This kind of full spectrum comfort is especially vital for people with allergies, asthma or other health conditions that restrict breathing.

• Use energy more efficiently: If you never wash or replace the filter, the dust and debris caught inside it makes the AC to strain even more. A clean filter preserves airflow, decreasing the unit’s workload and helping to manage your energy bills.

• Extend the system’s life span: Regularly maintaining the filter prevents the system from overheating, lowers wear and tear, and can even prolong your unit’s lifespan!

• Saving money: A clean filter reduces costs by tightening up your energy bills, preventing damage and minimizing the risk of early replacement for the AC.

Instructions for Washing Your AC Filter

Follow these instructions every one to three months to get all the benefits of a new air filter:

Prepare: As the first step, turn off the AC unit to prevent electrical hazards. Then, access your AC filter. It might be in the return air duct, in the air handler cabinet or inside the unit itself.

Remove the filter: Slowly take out the filter from its slot. Check for holes or tears. If the filter is torn, go ahead and change it.

Vacuum the filter: Get the brush attachment on your vacuum cleaner to get rid of dirt, hair, fibers and other loose debris.

Wash the filter: Take the filter outdoors and rinse it off with a garden hose. For a filter that’s as clean as possible, apply a mild detergent.

Dry the filter: Set the filter out to dry completely before reinstalling it. Before that happens, do not turn on your air conditioner or you risk allowing more dust particles inside the unit.

It’s helpful to remember that disposable filters cannot be washed. They should always be replaced after they become too clogged up with debris. The replacement filter should be the appropriate size to ensure compatibility with your AC unit.

Other Parts of an AC Unit to Maintain

Besides the air filter, additional AC parts need consistent upkeep for best performance and longevity. Call an HVAC professional for help servicing components including:

• The evaporator coils located in the indoor unit absorb heat from the air. Over time, these coils collect a lot of dust, which lowers heat transfer efficiency. Technicians apply a commercial-grade cleaning solution to eliminate dust and grime.
• The condenser coils found in the part of the unit kept outside get rid of heat removed from your home. These coils are subjected to the rain and snow, and become dirty very easily. Although you can lightly rinse off dirt, leaves and other debris with a garden hose, leave more thorough seasonal cleanings to a professional.
• The fan blades in your AC system will also accumulate dust and dirt. An HVAC technician will inspect the fan as part of an annual tune-up, washing and tightening the blades as needed to return to regular performance.
• The condensate drain line in your AC unit can become clogged up with algae, mold and debris. If this happens, choose a professional maintenance specialist to restore the drain line using a commercial cleaner or mold treatment.
