When it comes to clean and fresh indoor air, one of the most important things you do is replace your disposable filters regularly or clean your reusable air filter. If you don’t know how to clean a reusable air filter, we have step-by-step instructions for you here.

These trusty devices work tirelessly to trap dust, pollen, and other airborne particles, ensuring that the air we breathe is as pure as possible. But, just like any hardworking gadget, air filters need a bit of TLC to keep performing at their best. In this blog post, we’ll dive into the nitty-gritty of cleaning your reusable air filter, providing tips, tricks, and insights on why it’s crucial for the health of your home and your loved ones.

The Basics: How Often to Clean Your Reusable Air Filter

The million-dollar question: How often should you clean your reusable air filter? Well, the answer depends on a few factors such as your living environment, the type of filter you have, and the manufacturer’s recommendations. A good rule of thumb is to check your reusable filter every 1-3 months, and if it looks dirty, it’s time for a cleanup. Same for disposable air filters, but you’ll replace those with new ones. If you have pets or allergy sufferers in your home, your home’s air filters may require more frequent attention.

Step-by-Step: How to Clean a Reusable Air Filter

Follow these simple steps for reusable air filter maintenance.

1. Power Down

Before getting down and dirty, turn off your HVAC system. This prevents any loose particles from circulating in your home during the cleaning process.

2. Locate and Remove the Filter

Find the location of the filter media – it’s often situated near the air handler or furnace. Carefully remove the filter, taking note of how it’s installed.

3. Inspect the Filter

Give your reusable AC filter a once-over. Is it caked with dust and debris? Can you barely see through it? If so, it’s definitely in need of a clean.

4. Shake Off Loose Debris

Take your filter outside and give it a gentle shake to dislodge any loose particles. This will make the cleaning process more manageable.

5. Rinse or Vacuum

Depending on the type of filter you have, you can either rinse it with warm water or use a vacuum cleaner with a brush attachment. You can even use a garden hose if you prefer to do this outside. Wash both sides of the filter until you see clean water coming off of the filter. If rinsing, let the filter dry completely before reinstalling it.

6. Deep Clean (Optional)

For a deeper cleaning, you can soak your filter in a mixture of water and mild dish soap. Be sure to follow the manufacturer’s guidelines for cleaning solutions and duration.

7. Dry Before Reinstalling

Ensure the filter is completely dry before putting it back in place. A wet filter can lead to mold growth and reduced efficiency.

Tips and Tricks:

Mark Your Calendar

Set a reminder to check and clean your filter regularly. This simple habit can significantly improve your indoor air quality.

Have a Spare

Consider having a spare filter on hand. This way, you can easily swap out the dirty one without waiting for it to dry.

The Importance of a Clean Air Filter

Efficiency and Performance

A clean air filter allows your HVAC unit to operate efficiently. When clogged, the air conditioning works harder, leading to increased energy consumption and a higher utility bill.

Prolonged Lifespan

Regular cleaning extends the lifespan of your HVAC system. By reducing strain on the components, you can avoid costly repairs and premature replacements.

Improved Indoor Air Quality

A dirty filter can’t effectively capture airborne particles, allowing them to circulate in your home, drastically effecting your home’s air quality. Cleaning the filter ensures that you’re breathing in cleaner air and reduces the risk of respiratory issues.


From improved efficiency and energy savings to enhanced indoor air quality, a clean filter plays a vital role in maintaining a healthy and comfortable living environment. Make sure you keep up with air filter maintenance and check out our maintenance plans here for more extensive AC maintenance.
