Changing your Carrier furnace filter is simple. Turn off the power to the furnace at the breaker or power switch. Find the filter access panel and open it carefully, noting the airflow arrow direction, then slide out the old filter. Bryant-Carrier filters are available to purchase online in various sizes including 16x25x45, 20x20x5, 24x25x5, and other sizes. Dispose of the used Carrier infinity filter in a sealed bag and then insert the new one that is the proper size, ensuring the arrows point in the same direction as the old one. Close the access panel and restore the power. Change your Carrier air filters every 3 months or more often when they need it. 

To maintain healthy indoor air, using a clean filter is important for efficient HVAC system operation.
Turn off the power and find the filter behind the panel door or it could be in the return air duct. You might need to unscrew or unlatch the panel to open it. Look at the way the arrow is pointing on the old filter. If it's a disposable Bryant furnace filter, replace it with a new one. If it's a reusable filter, run it under water and make sure it's dry before reinstalling it. Slide it back into its proper position, and match the direction of the arrow. Then shut the access panel door. Restore power to the unit. Check it monthly and clean it every 1-3 months. If your system is more complex, contact an HVAC technician to help you. 

To remove Bryant air filters, make sure you look at the position of the old one first and notice the way the arrow is pointing. You’ll want to place the new one so the new arrow points in the same direction. You can find the air filter by opening the access panel on your unit which is usually on the side or on the return air duct. You may have to unscrew the door or remove the latch to access it. 

Your HVAC system can develop significant issues if your Bryant filter replacement is installed the wrong way., It can reduce your airflow and force the blower motor to work harder. It also won’t work as efficiently and could lead to uneven heating, cooling, and even increase your utility bills. A backward filter might not seal the right way, allowing dust, pollen, and other contaminants to bypass your filter and enter your ductwork, which can cause health problems. Debris could accumulate on HVAC parts and cause it to overheat, start a fire, or get damaged. All of this causes wear and tear on your system and the damage could be expensive to fix. To ensure your HVAC system continues to work properly, always verify the airflow arrow is placed in the proper direction. 

The Carrier Infinity Air Purifier's high-efficiency filter typically needs replacing every 8 to 12 months, though this timeframe can vary. Air quality significantly influences filter lifespan; homes in polluted areas or those with pets or allergies may require more frequent changes.

Usage also plays a role, as heavier HVAC system use leads to more air filtration and quicker filter soiling. Regularly inspecting the filter for visible dirt or clogging is essential, and if it appears dirty, it should be changed regardless of the time elapsed. Reduced airflow from vents, worsening allergy symptoms, or a filter replacement indicator on the system can also signal the need for a new filter. While checking the filter every month or two is recommended, consulting the manufacturer's instructions for specific recommendations and considering professional HVAC maintenance can further refine the ideal replacement schedule. Ultimately, monitoring the filter's condition and being attentive to any warning signs are the most reliable ways to determine when a replacement is necessary.

Carrier air purifier filters use different filtration technologies. Some are washable and reusable and others are disposable and need replacement. Washable filters need to be cleaned consistently by rinsing them under water and allowing them to dry before reinstalling them.

Disposable filters need to be replaced every 1 to 3 months. Washing disposable filters or vacuuming them can damage the filter. Most HEPA filters are disposable and so are most activated charcoal filters. Check your owners manual to learn which type you have and for cleaning instructions. Disposable filters are usually paper like and pleaster, while washable filters are usually made of mesh or foam. Cleaning a disposable filter can be harmful. If you still can’t determine what you have or how to remove and replace it, call an HVAC technician to help you.

The Carrier Infinity Air Purifier is a worthwhile investment because it can improve your indoor air quality. Removing most airborne particles can create a healthy home environment.  These units offer purification for your entire home rather than just in one room like a portable air purifier. Some integrate with your HVAC system to keep you and your family healthier providing better air quality.
