Washing Your AC Air Filter and Why It’s Helpful

When was the last time you checked your air conditioner filter? As a general rule, you should check it once a month and take the appropriate steps when it gets dirty. We’ll share details about the multiple types of AC filters, why they need regular care and easy-to-follow instructions on how to clean reusable filters effectively.

Kinds of AC Filters

Your filter design influences indoor air quality, airflow efficiency and whether you can clean or swap it out when it becomes dirty. Here’s an overview of some popular models:

• Disposable filters are commonly made using fiberglass with a paper frame. These filters are intended for short-term use and should be changed every 1 to 3 months. They are usually low cost and simple to put in but not very environmentally friendly because they generate waste.
• Reusable filters have sturdier frame materials such as aluminum or plastic. These filters can be washed and reused multiple times, often lasting several years if cared for correctly. They are more environmentally friendly and budget friendly over time. That being said, cleaning them takes additional time and effort than simply replacing a disposable model.
• Electrostatic filters utilize static electricity to capture particles effectively while maintaining airflow. These can be either disposable or reusable. Reusable electrostatic filters require regular washing to maintain their effectiveness.
• HEPA filters, or high-efficiency particulate air filters, are the most effective filters around, removing 99.97% of airborne particles as small as 0.3 microns. Most HEPA filters are single use, but they remain effective for up to one year before requiring replacement. While they deliver superior filtration, they are higher priced and aren’t always compatible with all HVAC systems.

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

It’s a simple chore to forget about, but rinsing or replacing your AC filter is important for a few reasons:

1. Improved air quality: A new filter captures dust, pollen, pet dander and other particles, keeping your indoor air fresher and contamination free. This plus is especially vital for people with allergies, asthma or other health conditions that restrict breathing.

• Energy efficiency: If you never clean or replace the filter, the dust and debris slowly filling it it makes the AC to exert even more energy. A clean filter restores airflow, decreasing the unit’s workload and putting a stop to an increase in your energy bills.

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

• Saving money: A fresh filter saves money by cutting your energy bills, avoiding damage and minimizing the risk of early replacement for the AC.

Your Guide to Cleaning Your AC Filter

Use these instructions every one to three months to continue enjoying all the perks of a clean air filter:

Prepare: As the first step, turn off the AC unit to avoid electrical hazards. Then, find 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: Carefully pull out the filter from the slot. Check for holes or tears. If the filter is visibly damaged, go ahead and replace it.

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

Wash the filter: Bring the filter outdoors and rinse it off with a garden hose. For a filter that’s as clean as possible, add a small amount of a mild detergent.

Dry the filter: Place the filter out to air dry completely before reinstalling it. But before you do so, don’t run your air conditioner or you risk getting more dust particles right back into the system.

It’s necessary to note that disposable filters cannot be washed. They should always be replaced when they become too clogged up with debris. The replacement filter should be the appropriate size to make sure there’s compatibility with your AC unit.

Other Parts of an Air Conditioning System to Clean

In addition to the air filter, other AC parts require regular upkeep for best operation and minimal expense. Reach out to an HVAC contractor for help servicing parts like:

• The evaporator coils inside the indoor system remove heat from the air. After enough time, these coils collect a lot of dust, which lowers heat transfer efficiency. Professionals apply a special cleaning solution to remove dust and grime.
• The condenser coils found in the outdoor unit release heat removed from your home. These coils are left out in the elements and get dirty very easily. Even though you can lightly rinse off dirt, leaves and other debris by grabbing a garden hose, leave more detailed seasonal servicing to a professional.
• The fan blades in your AC system will also accumulate dust and dirt. An HVAC professional will check the fan as part of an annual tune-up, wiping down and tightening the blades as needed to restore regular performance.
• The condensate drain line in your AC system can become clogged up with algae, mold and debris. Should this happen, contact a certified maintenance specialist to restore the drain line using a commercial cleaner or algaecide.
