Follow these air filter replacement tips to keep your Boca Raton home's indoor air clean.

When to Replace Air Filters

Most standard, disposable pleated air filters need replacing every 1 to 3 months. Write the date you install each new filter with a permanent marker right on the filter frame. That makes it easy to check when it's time for a new one. A good rule of thumb is to replace filters at the start of each new season.

You may need to replace filters more often if you have pets or indoor allergies. Check your filters at least monthly by holding them up to a bright light. If you can't see light passing through them, they are overdue for a change. Extremely dirty filters can even cause your system to freeze up and shut down.

Another sign it's time for new air filters is if rooms feel stuffy, dust accumulates quickly after cleaning, or family members start having allergy symptoms.

What Type of Filter to Use

The most common residential air filters are disposable pleated filters made of lightweight fiberglass or cotton/polyester blend materials. They come in standard sizes to fit typical home HVAC systems. These basic filters trap larger dust and debris particles.

Upgrading to a medium efficiency filter offers better filtration. Look for a Minimum Efficiency Reporting Value (MERV) rating of 7 to 12. The higher the MERV rating, the more microscopic allergens and particles the filter captures.

Pleated filters with a MERV of 13 to 16 are considered high efficiency. They filter out even smaller pollutants like mold spores and bacteria. However, the denser material also creates higher air resistance. Make sure your HVAC fan motor is powerful enough to push air through a HEPA or other high efficiency filter.

For the best air purification, consider installing a whole-house electronic air cleaner. Electronic air cleaners use an electrically charged grid to pull in and trap particles. However, they are more expensive to buy and operate. Make sure to keep the pre-filter cleaned so the electronic cell doesn't get clogged.

Proper Air Filter Installation

Installing new air filters correctly ensures they filter properly. Here are some tips for proper air filter installation:

- Turn off your HVAC system so the fan doesn't turn on while changing the filter.

- Locate the existing filter. They are usually found in the return air duct just before the blower motor. Your owner's manual should show the filter location.

- Check which direction the arrow on the filter frame points. Arrows indicate the proper direction of airflow. Air should pass through the filter, moving toward the blower motor.

- Make sure the filter fits snugly in the frame without any gaps around the edges. Gaps can allow air to bypass the filter.

- Do not use extra material to try to extend the filter or make it thicker. That stresses your system.

- Align the filter with the grooves in the metal filter track. Slide it into place following the direction of the airflow arrow.

- Secure any closure clips or thumbscrews on the filter frame once the filter is fully inserted.

- Check that the filter is firmly seated in the opening. Adjust it if needed so air cannot sneak around it.

- Turn the HVAC system back on and make sure the blower runs properly without any rattling noises.

- Write the install date on the air filter frame with a marker. That makes it easy to check the recommended replacement timeframe.

Following proper air filter installation ensures cleaner, healthier indoor air for your Boca Raton home.

Maintenance Tips for optimal AC air filtration

-When changing filters, inspect the return ducts for any mold or clogs which also need cleaning.

-Use a cover over floor vents to catch debris before it enters the duct system.

-Have a professional clean the ducts every 3-5 years to remove built up allergens.

-Install a whole-house air purifier for cleaner air throughout your home.

-During construction projects, use filter media with a MERV 8-13 to protect equipment from dust.

-Keep humidity levels below 50% to help filters remain effective at trapping particles.

-If you have pets or allergies, consider installing a high efficiency filter to create cleaner indoor air.


Remember to change your AC unit's air filters regularly for optimal performance. Follow the manufacturer's recommended replacement timeframe, usually every 1-3 months. Select the proper filter size and efficiency for your equipment. Carefully install new filters in the correct directional airflow to prevent air bypass.
