The Frigidaire refrigerator model FRSS23L3AB air filter is an effective solution for reducing odors and maintaining freshness inside your refrigerator. Activated carbon technology captures and neutralizes odor-causing particles from foods such as fish, onions, garlic, cheese, and leftovers before they circulate throughout the compartment. This helps prevent unwanted odor transfer and supports the natural flavor of stored groceries. The PAULTRA2 filter continuously works with the refrigerator's airflow system to help maintain a cleaner and more pleasant storage environment.

The replacement air filter for Frigidaire FRSS23L3AB fits compatible refrigerators that use the PureAir Ultra II filtration system and installs quickly without tools. Regular replacement helps maintain effective odor control and supports long-lasting refrigerator freshness. Replacing the filter every six months helps keep the filtration system working efficiently. Order today to enjoy cleaner refrigerator air, better food storage conditions, and a fresher environment for your family's favorite foods and beverages.

Frigidaire PureAir Ultra II (PAULTRA2) replacement refrigerator air filter is compatible with model FRSS23L3AB

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 FRSS23L3AB use?
A: Your Frigidaire refrigerator uses the PureAir Ultra II (PAULTRA2) air filter, which helps reduce food odors and keeps the refrigerator smelling fresh.
