Frigidaire Professional 22.3 Cu. Ft. French Door Fridge Model FPBG2278UF4 uses PAULTRA2 replacement air filter
The Frigidaire Professional refrigerator model FPBG2278UF4 air filter supports a fresher kitchen by keeping odors under control. Foods stored together, including garlic, onions, seafood, cheese, leftovers, sauces, and cooked meals, can produce odors that move through the compartment. The PAULTRA2 filter's activated carbon filtration helps absorb odor-causing particles before those smells spread to nearby groceries. This helps protect the freshness of fruits, vegetables, beverages, dairy products, snacks, and ready-to-eat meals.
The replacement air filter for Frigidaire FPBG2278UF4 is a simple maintenance part for compatible refrigerators using the PureAir Ultra II filtration system. It is easy to replace and helps keep your appliance performing well for daily food storage. Regular replacement every six months ensures cleaner air circulation and steady odor control.

The air filter uses activated carbon technology to continuously circulate and purify the air inside your refrigerator — neutralizing odors from foods like fish, leftovers, and produce before they spread or affect flavor.
Our certified filtration system targets and removes a wide range of harmful contaminants and odors.
Activated carbon saturates over time. Replacing every 6 months ensures continuous odor and gas adsorption — even if the filter looks clean.
When your fridge's air filter indicator turns red or begins flashing, replace immediately. The sensor tracks usage and airflow performance automatically.
If odors linger inside a clean fridge, your air filter is exhausted. Don't wait for the indicator — trust your nose and replace it promptly.
