The Frigidaire refrigerator model FRSS2323AB air filter helps maintain a fresh and pleasant refrigerator environment by reducing unwanted food odors before they spread. Using activated carbon technology, the PAULTRA2 filter captures odor-causing particles from foods such as onions, garlic, fish, and leftovers. This helps preserve the natural taste of fruits, vegetables, dairy products, and beverages while keeping the refrigerator compartment smelling cleaner. Unlike baking soda, this refrigerator air filter works continuously with the appliance's airflow system to provide reliable odor control throughout the day.

The replacement air filter for Frigidaire FRSS2323AB is easy to install and requires no tools. Designed for compatibility with the PureAir Ultra II filtration system, it helps maintain effective odor absorption and a fresher storage environment for your groceries. Replacing the filter every six months supports optimal performance and helps keep your refrigerator smelling clean. Browse all Frigidaire air filters or order today and enjoy a fresher refrigerator every time you open the door.

Frigidaire PureAir Ultra II(PAULTRA2) Replacement Refrigerator Air Filter is compatible with model FRSS2323AB

Key Features

Active Carbon Absorption: Chemically traps and permanently neutralizes intense food odors at a molecular level instead of masking them.
15x Faster Than Baking Soda: Integrates directly with internal fan loops to actively scrub air channels rather than relying on passive absorption.
Flavor Shield Protection: Traps airborne gases so sensitive items like fresh milk, butter, and open ice trays never absorb leftover smells.
High-Capacity Wave Profile: Accordion-style corrugated layout maximizes active surface area for maximum odor retention in a compact frame.
6-Month Lifespan Performance: Delivers continuous, heavy-duty odor elimination for up to 180 days before needing a quick, tool-free swap.

When to Replace Your Water Filter

Every 6 Months or 200 Gallons

Most refrigerator water filters are designed to last approximately 6 months or filter up to 200 gallons of water — whichever comes first.

When Your Fridge Displays a Filter Alert

Modern LG, Samsung, Whirlpool, and Frigidaire refrigerators have built-in filter indicators that notify you when it's time for a replacement.

Changes in Taste, Odor, or Flow

A drop in water pressure, an unusual taste, or an off smell from your dispenser are clear signs your filter is overdue for a change.

Frequently Asked Questions

Q: Which air filter does the Frigidaire refrigerator model FRSS2323AB use?
A: Your Frigidaire refrigerator uses the PureAir Ultra II (PAULTRA2) air filter, which helps reduce food odors and keeps the refrigerator smelling fresh.

Q: Can I use baking soda instead of an air filter?
A: While baking soda may absorb some odors, the PureAir Ultra II filter actively filters circulating air and is designed to provide more effective odor control inside the refrigerator. Browse our full range of Frigidaire air filters for the right fit for your model.

Q: What happens if I don't replace the air filter?
A: An expired filter may lose its ability to absorb odors effectively, allowing strong food smells to spread throughout the refrigerator and affect the freshness of other items.

Q: Can I wash and reuse the filter?
A: No. The PAULTRA2 is a disposable filter and should be replaced with a new one when it reaches the end of its service life. Shop replacement packs in our refrigerator air filter store.

Q: How to replace the Frigidaire FRSS2323AB air filter?
A: Replacing the filter is simple and tool-free. Open the refrigerator, locate the filter housing, remove the old filter, and insert the new one.
