The Ultimate Guide to Air and Water Filters for Your Frigidaire Professional Refrigerator​

2025-11-26

Maintaining the peak performance of your Frigidaire Professional refrigerator hinges on the regular and correct replacement of its air and water filters. Using genuine Frigidaire brand filters, which are specifically designed for your model, is the single most important action you can take to ensure the highest quality ice and water, eliminate food odors, and protect the refrigerator's internal systems. This comprehensive guide provides all the necessary information to confidently select, install, and maintain the air and water filters for your appliance.

​Understanding the Two Filter Systems in Your Frigidaire Professional Refrigerator​

Frigidaire Professional refrigerators typically utilize two distinct filtration systems, each with a unique purpose. Understanding the difference is crucial for proper maintenance.

The ​water filter​ is the more familiar of the two. Its primary job is to reduce contaminants from the water that enters your refrigerator. This includes the water used for the built-in dispenser on the door and the water that is frozen to make ice cubes. A clean water filter ensures your drinking water and ice taste fresh and are free from impurities. The filtration process involves water passing through a dense carbon block or other specialized media that traps sediments, chlorine, and other particles.

The ​air filter, sometimes called an odor filter, is dedicated to improving the environment inside the refrigerator compartment. It actively scrubs the air of odors, preventing flavor transfer between different foods. This means your vanilla cake will not taste like the onion you saved from last night's dinner. The air filter contains materials, often including activated carbon, that absorb and neutralize odor molecules as air circulates inside the fridge. It is important to note that not all models have a replaceable air filter; some have an built-in air purification system that does not require regular replacement.

​Identifying the Correct Filter Models for Your Refrigerator​

Using the wrong filter can lead to leaks, poor performance, or even damage. Therefore, identifying the exact filter models compatible with your specific Frigidaire Professional refrigerator is an essential first step. The easiest and most reliable method is to check your refrigerator's model number.

The model number is usually located inside the main refrigerator compartment. Look for a sticker on the inner sidewall or on the ceiling. The model number is a combination of letters and numbers, such as "FPFU19F8WFB" or "PRHS39LZJF." Once you have this number, you can visit the official Frigidaire website and use their filter finder tool. Simply enter your model number, and the site will display the exact water and air filter models designed for your unit.

You can also find the filter numbers printed on the existing filters themselves. For the water filter, the model number (like ​ULTRAWF​ or ​PureSource Ultra® II Filter EPTWFU01) is on its label. The air filter, if your model has one, will also have a part number, such as 5303918459. Always cross-reference these numbers with the owner's manual or the Frigidaire website to ensure accuracy. ​Using the correct Frigidaire brand filter is non-negotiable for optimal performance and to maintain your appliance's warranty.​​

​Step-by-Step Guide to Replacing the Water Filter​

Replacing the water filter is a simple process that usually takes less than five minutes. Most Frigidaire Professional models have an indicator light on the control panel that illuminates when it is time for a change. The general replacement interval is every six months, but this can vary based on your household's water usage and quality.

  1. ​Locate the Filter Housing:​​ The water filter compartment is typically located in the upper right-hand corner of the fresh food compartment. Some models may have it in the grille at the bottom of the refrigerator.
  2. ​Prepare for Water Release:​​ Place a towel or a shallow cup on the floor of the refrigerator compartment directly beneath the filter housing. A small amount of water may spill out during the change.
  3. ​Open the Filter Cap:​​ Press the button or latch to open the cap covering the filter.
  4. ​Remove the Old Filter:​​ Grasp the old filter and turn it counterclockwise until it releases. Pull it straight out.
  5. ​Prepare the New Filter:​​ Remove the protective covering from the O-rings and the inlet of the new filter.
  6. ​Insert the New Filter:​​ Align the new filter and insert it into the housing. Turn it clockwise until it stops and locks into place. Do not overtighten.
  7. ​Close the Cap and Reset the System:​​ Securely close the filter cap. It is critical to ​reset the water filter indicator light​ after replacement. Consult your owner's manual for the specific button sequence, but it often involves holding the "Filter Reset" or "Light" button for 3-5 seconds until the light turns off.
  8. ​Flush the System:​​ Run water through the dispenser for at least 3-5 minutes to clear air from the lines and activate the carbon filter. Discard the first few batches of ice.

​Step-by-Step Guide to Replacing the Air Filter​

The air filter replacement process is even more straightforward. The interval for changing the air filter is generally once a year.

  1. ​Locate the Air Filter Housing:​​ The air filter is always located inside the refrigerator compartment. Common locations are on the back wall, on the ceiling, or in a dedicated slot on the inner sidewall.
  2. ​Remove the Old Filter:​​ The housing is usually covered by a vent or a simple lid. It may slide out, snap out, or be held by a couple of screws. Open the cover and pull the old filter straight out.
  3. ​Insert the New Filter:​​ Unpackage the new air filter and remove any protective film. Insert it into the housing, ensuring it is oriented correctly (there are usually arrows indicating the direction of airflow).
  4. ​Close the Housing and Reset:​​ Secure the cover back in place. Similar to the water filter, you must ​reset the air filter indicator light​ on the control panel. The procedure is typically the same as resetting the water filter indicator.

​The Critical Importance of Using Genuine Frigidaire Filters​

While third-party or generic filters may be less expensive, they pose significant risks to your refrigerator and your health.

  • ​Performance and Filtration Guarantee:​​ Genuine Frigidaire filters are engineered to work seamlessly with the water pressure and flow rates of your specific refrigerator model. They are certified by independent organizations like NSF International to reduce specific contaminants, a claim that many off-brand filters cannot reliably make.
  • ​Fit and Leak Prevention:​​ Authentic filters are precision-made to fit perfectly. An ill-fitting generic filter can cause leaks, which can lead to water damage inside your refrigerator and on your floor.
  • ​System Protection:​​ The wrong filter can restrict water flow, putting undue strain on the refrigerator's water valve and ice maker, potentially leading to costly repairs.
  • ​Warranty Compliance:​​ Using a non-genuine filter could void the warranty on your refrigerator, especially if a failure can be traced back to the filter.

​Troubleshooting Common Filter-Related Issues​

Even with proper installation, you may encounter occasional issues.

  • ​Water Pressure is Slow at the Dispenser:​​ This is often the first sign of a clogged filter. If it has been nearly six months since the last change, replace the water filter. If the problem persists immediately after a change, ensure the filter is installed correctly and that its protective seals were removed.
  • ​Water or Ice Tastes Bad:​​ A bad taste usually indicates that the water filter is exhausted and needs replacement. If the taste remains after changing the filter, run more water through the system to fully flush it.
  • ​Water is Leaking from the Filter Housing:​​ The most common cause is that the filter is not fully seated and locked into place. Turn it clockwise until it stops. If it still leaks, the O-rings on the filter may be damaged or missing; ensure the new filter's O-rings are intact and lubricated by a drop of water.
  • ​The Filter Indicator Light Will Not Reset:​​ Double-check the steps in your owner's manual. Sometimes, you need to hold the button for a longer duration. If it still does not reset, a power cycle (unplugging the refrigerator for 60 seconds) can sometimes resolve the issue.

​Where to Purchase Authentic Frigidaire Professional Filters​

To guarantee you are getting a genuine product, purchase from authorized retailers.

  • ​Official Frigidaire Website:​​ This is the most reliable source.
  • ​Authorized Appliance Retailers:​​ Stores that are official partners of Frigidaire.
  • ​Large, Reputable Online Marketplaces (with caution):​​ If purchasing from a site like Amazon, ensure the seller is "Frigidaire" or an authorized distributor. Be wary of prices that seem too good to be true, as they may indicate counterfeit products.

By following this detailed guide, you will ensure your Frigidaire Professional refrigerator continues to provide clean, great-tasting water and ice while keeping your food fresh and odor-free for years to come. Consistent filter maintenance is a small investment that pays significant dividends in appliance performance and household health.
