Cleaning Your AC Air Filter and Why It’s Necessary

How long has it been since  you inspected your air conditioner filter? As a rule of thumb, you should examine it each month and take the appropriate steps when it looks dirty. Find out what you should know about the different types of AC filters, why they require regular care and easy-to-follow instructions on how to clean and replace reusable filters effectively.

The Available Types of AC Filters

Your filter choice impacts indoor air quality, ventilation efficiency and whether you should wash or change it when it becomes old. Here’s a breakdown of some common models:

• Disposable filters are commonly made from fiberglass and a paper frame. These filters are intended for short-term use and are best swapped out every 30 to 90 days. They are typically inexpensive and simple to install but less environmentally friendly as they are eventually thrown away.
• Reusable filters have more durable frame materials made with metals like aluminum or plastic. These filters can be washed and reused again, often lasting several years if maintained properly. They are more environmentally friendly and budget friendly over their life span. That being said, washing them takes more time and effort than simply replacing a disposable filter.
• Electrostatic filters use static electricity to capture airborne particles effectively while preserving airflow. These can be both disposable or reusable. Reusable electrostatic filters need regular upkeep to preserve their effectiveness.
• HEPA filters, or high-efficiency particulate air filters, are the most effective filters of all, removing 99.97% of airborne particles down to 0.3 microns. Most HEPA filters are disposable, but they remain effective for up to an entire year before requiring replacement. While they deliver exceptional filtration, they are higher priced and aren’t compatible with all HVAC systems.

Why Should You Wash or Replace Your AC Filter? 4 Reasons Why

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

1. Better air quality: A new filter traps dust, pollen, pet dander and other particles, keeping your indoor air purer and healthier. This plus is especially crucial for people with allergies, asthma or other health issues.

• Use energy more efficiently: If you never clean or change your filter, the dust and debris clogging it causes the AC to strain even more. A new filter optimizes airflow, reducing the unit’s workload and helping rein in your energy bills.

• Extend the system’s life span: Regularly cleaning the filter can help keep the system from overheating, reduces wear and tear, and can even prolong your unit’s lifespan!

• Cost savings: A fresh filter saves money by cutting your energy bills, preventing damage and minimizing the risk of unexpected AC replacement.

A Step-by-Step Guide to Washing Your AC Filter

Use these steps every one to three months to enjoy all the benefits of a clean air filter:

Prepare: First, shut off the AC unit to avoid electrical fire or similar hazards. Then, access your AC filter. It will most likely be found in the return air duct, in the air handler cabinet or inside the unit itself.

Remove the filter: Gently pull out the filter from its slot. Check for holes or tears. If the filter is ripped, go ahead and replace it.

Vacuum the filter: Grab the brush add-on for your vacuum cleaner to get rid of dirt, hair, fibers and other particles.

Wash the filter: Bring the filter outdoors and spray it down with a garden hose. For a more thorough clean, use a mild detergent.

Dry the filter: Set the filter out to air dry completely before putting it back. But before you do so, don’t use your air conditioner or you risk allowing more dust particles inside.

It’s necessary to note that disposable filters cannot be washed. They must be thrown away after they become clogged with dust. The replacement filter should be the same size to confirm compatibility with your AC unit.

Additional Components of an AC Unit to Clean

Besides the filter, additional AC parts need regular servicing for peak performance and longevity. Contact an HVAC technician for help maintaining parts like:

• The evaporator coils within the air handler remove heat from the air. Over time, these coils gather a lot of dust, which lowers heat transfer efficiency. Professionals employ a special coil cleaner to eliminate dust and grime.
• The condenser coils located in the outdoor unit expel heat taken out of your home. These coils are left out in the worst weather and become dirty quickly. While you can lightly rinse off dirt, leaves and other debris using a garden hose, leave more detailed seasonal servicing to a professional.
• The fan blades in your AC system will also gather dust and dirt. An HVAC contractor will check the fan as part of their yearly tune-up, cleaning and aligning the blades as necessary to restore regular performance.
• The condensate drain line in your AC unit can become clogged up with algae, mold and debris. Should this happen, choose a qualified contractor to clean the drain line using a strong cleaning solution or algaecide treatment.
