Improve The Air Quality In Your Home: Here’s How To Change Your Air Filter

Maintaining a clean and healthy indoor environment is crucial for overall well-being. One essential aspect of this is regularly changing your air filter. Whether you’re a seasoned homeowner or a first-time renter, understanding how to change air filter in your home is vital for ensuring optimal air quality.

Step 1: Locate Your Air Filter

Air filters are typically located in one of the following areas:

• Central air system: Inside the air handler unit, usually in the basement or attic.
• Window air conditioner: Behind the front panel of the unit.
• Portable air purifier: Inside the device itself.

Step 2: Determine the Filter Size

Once you’ve located the air filter, measure its dimensions: length, width, and thickness. You can also refer to the manufacturer’s recommendations or the old filter for the correct size.

Step 3: Choose the Right Filter Type

There are various types of air filters available, each with different levels of efficiency and filtration capabilities. Consider the following factors:

• MERV rating: Measures the filter’s ability to capture particles.
• Pleating: Filters with more pleats have a larger surface area for trapping contaminants.
• Filtration technology: Some filters use advanced technologies like HEPA or activated carbon for enhanced filtration.

Step 4: Replace the Old Filter

• Turn off the HVAC system or unplug the appliance.
• Remove the old filter by sliding it out of its slot.
• Insert the new filter in the correct direction, as indicated by arrows or labels.
• Secure the filter in place.

Step 5: Reset the Filter Indicator

Some HVAC systems have a filter indicator light that alerts you when it’s time for a change. Once you’ve replaced the filter, reset the indicator by following the manufacturer’s instructions.

Step 6: Schedule Regular Replacements

The frequency of air filter replacements depends on the type of filter, usage, and environmental conditions. As a general rule:

• Monthly: High-efficiency filters (MERV 13 or higher)
• Every 2-3 months: Standard filters (MERV 8-12)
• More frequently: If you have pets, smoke, or live in a dusty area

Benefits of Changing Your Air Filter

Regular air filter changes bring numerous benefits:

• Improved air quality: Removes allergens, dust, and pollutants from the air.
• Enhanced comfort: Reduces respiratory irritation and improves sleep quality.
• Energy efficiency: Clean filters allow air to flow more easily, reducing energy consumption.
• Extended HVAC lifespan: Prevents dust buildup in the system, prolonging its life.

Summary: A Healthy Home, One Filter at a Time

Changing air filter in your home is a simple yet essential task that can significantly impact your indoor air quality and overall health. By following these steps and scheduling regular replacements, you can create a cleaner, healthier, and more comfortable living environment for yourself and your loved ones.
