How to Know If Frigidaire PAULTRA2 Pure Air Ultra II Is the Right Refrigerator Air Filter for Your Model

Frigidaire refrigerators, especially Gallery and Professional series, use advanced air filtration systems. Many owners get confused when they see PAULTRA2 (Pure Air Ultra II) on their filter or in the manual.

If your fridge smells off or you are unsure whether PAULTRA2 is the correct replacement, this guide will help you verify compatibility, understand the filter, and avoid buying the wrong one.

Why Frigidaire Air Filter Numbers Can Be Confusing

Frigidaire uses different air filter types across their refrigerator lines:

  • Older models may use PureAir AF-1 or other variants.
  • Newer Gallery and Professional models often require the Pure Air Ultra II (PAULTRA2).
  • Product listings and manuals sometimes list multiple part numbers or cross-references.
  • Some filters look similar but have different shapes or connection types.

Choosing the wrong air filter means poor odor control or the filter may not fit properly.

Where to Find Your Frigidaire Air Filter Model Number

Follow these simple steps to identify the correct filter:

  1. Check the old filter. Remove the current air filter and look for PAULTRA2 or Pure Air Ultra II printed on the label.
  2. Look inside the filter compartment. Usually located at the top of the fresh food compartment (often behind a removable panel or on the left or right side).
  3. Check your refrigerator manual. Search for air filter or PureAir in the manual.
  4. Locate the model plate. Inside the fridge (on the wall or ceiling). Use the model number to verify compatibility.
  5. Use Frigidaire’s parts lookup. Enter your refrigerator model number on the official Frigidaire website.

If the filter reminder light is on, it is likely time to replace it with PAULTRA2.

What Is Frigidaire PAULTRA2 Pure Air Ultra II?

PAULTRA2 is Frigidaire’s advanced refrigerator air filter featuring activated carbon technology. It is significantly more effective than traditional baking soda at capturing and neutralizing food odors (onion, garlic, fish, etc.).

It is designed specifically for select Frigidaire Gallery and Professional series refrigerators with Pure Air Ultra II systems.

Key Features of PAULTRA2

  • Uses activated carbon to absorb and trap odor-causing molecules.
  • Keeps your refrigerator smelling fresh for up to 6 months.
  • Easy, tool-free installation.
  • Designed exclusively for compatible Frigidaire and some Electrolux models.

Compatibility Checklist Before Buying

Use this checklist to confirm PAULTRA2 is right for your fridge:

  • Does your current filter say PAULTRA2 or Pure Air Ultra II?
  • Is your refrigerator a Frigidaire Gallery or Professional series?
  • Is it a French door or side-by-side model with Pure Air Ultra II system?
  • Does the filter shape match (rectangular cartridge approx. 3.8 x 1.8 inches)?
  • Does your model number appear in the official compatibility list?

If yes to most questions, PAULTRA2 is the correct choice.

Common Mistakes When Buying Frigidaire Air Filters

  • Buying based only on Frigidaire brand without checking the exact model number.
  • Confusing PAULTRA2 with older PureAir AF-1 or other air filters.
  • Purchasing generic filters that do not fit the housing properly.
  • Ignoring the filter label on the existing cartridge.
  • Forgetting to reset the filter change indicator after installation.

  • Reduced freshness even after cleaning

Regular replacement keeps your fridge smelling clean and helps maintain food quality longer.
