Frigidaire PAULTRA2 PureAir Ultra II Air Filter Replacement Guide

Confirm PAULTRA2 before opening the package

The useful identity is the full pairing: PAULTRA2 / PureAir Ultra II. “PureAir,” “Ultra,” or “refrigerator air filter” alone is incomplete. Frigidaire also sells FRGPAAF2 under the PureAir RAF-2 name. Those are separate manufacturer part numbers and should not be treated as alternate spellings, generations that automatically replace one another, or interchangeable pieces.

Start at the permanent appliance label. The Frigidaire model-number guide explains how to capture the complete identifier rather than a shortened sales name. Open the official manual and parts information tied to that model, then use the Frigidaire air-filter selector to preserve the match. The installed filter is useful supporting evidence, but a prior owner may have installed the wrong media or moved a cover between appliances.

Frigidaire’s current PAULTRA2 product page calls it the PureAir Ultra II Air Filter, describes carbon technology that captures undesirable smells, says installation needs no tools, and recommends replacement every six months. HomeMemory’s verified exact-product Amazon ASIN is B07LD37KTF. An ASIN helps distinguish a marketplace listing; it does not override the appliance manual or guarantee that a listing has not changed. Recheck the displayed brand, part number, count, and seller before purchase.

Understand what this filter can and cannot do

PAULTRA2 sits in the refrigerator’s recirculating air path to help manage food odors. It is not a water cartridge, does not connect to plumbing, and does not filter dispenser water or ice. There is no priming or gallon-based flush after installation. If a procedure tells you to dispense several glasses of water, you are reading instructions for a different maintenance item.

An air filter is also not a substitute for sanitation. Spoiled food, an open onion, a leaking package, liquid under a drawer, a dirty drain area, or odor absorbed into an ice bin can overwhelm new media. Remove the source, clean owner-removable surfaces using the appliance manual, dry the cabinet, and keep vents clear. The filter supports odor control after source removal; it should not be expected to mask decay or a persistent chemical smell.

A warm cabinet, blocked vent, fan noise, frost buildup, or door-seal problem needs cooling diagnosis. Do not interpret every smell or airflow change as evidence that PAULTRA2 is exhausted.

Choose the right replacement time

Frigidaire’s general owner guidance says to replace refrigerator air filters every six months, and notes that most equipped models prompt through a filter-status light. The company also says the period may be adjusted according to the types and amounts of food normally stored. Treat six months as the routine planning interval, not a promise that every household will experience identical odor loading.

Replace sooner when the exact model manual directs it, the air-filter indicator becomes due, the media was contaminated by a spill, or recurring food odors return after the actual source has been removed and the cabinet cleaned. Heavy storage of aromatic foods may load odor-adsorbing media faster. A reminder that appears early should be checked against the installation record before blindly replacing or resetting it.

Do not extend service indefinitely merely because the refrigerator smells acceptable. Gradual odor change is hard to notice, and a reminder is easiest to trust when the last installation date was recorded. The Frigidaire air-filter interval guide explains how to set a household-specific schedule without confusing air and water maintenance.

Prepare the refrigerator and work area

Read the air-filter section of the exact Use & Care Guide before touching the cover. Frigidaire describes PAULTRA2 as a no-tool replacement, but cover location, release motion, filter orientation, and reset buttons belong to the refrigerator model. Do not borrow a video from a visually similar French-door refrigerator and assume the tabs are identical.

Wash and dry your hands. Keep the new filter sealed until you have exposed the old one and confirmed the label and shape. Move fragile food away from the work area, but avoid leaving perishables at room temperature longer than necessary. Photograph the old filter’s orientation and the closed housing. That small record is valuable when arrows or printed labels are difficult to see.

No pliers, screwdriver, lubricant, adhesive, knife, or tape should be needed. A towel can protect a shelf from crumbs, but there should be no pressurized water. If liquid is present around the air-filter housing, find its source instead of assuming it came from the dry filter.

Remove the old PureAir Ultra II filter

Open or release the filter cover exactly as the manual illustrates. Support the cover rather than bending it past its stop. Remove the old filter or holder with steady hand pressure and note which surface faces the airflow. Some model designs place replaceable media in a reusable holder; others present an assembly differently. The model documentation, not a universal internet sequence, controls.

If the cover will not release, stop. Check whether food bins or shelves block normal access and whether the documented press, slide, or pull motion is being used. Do not pry against the refrigerator liner. A cracked tab can turn a routine consumable change into a service repair.

Compare the removed label with the unopened replacement. Both should identify PAULTRA2/PureAir Ultra II when that is the family confirmed for the refrigerator. If the old piece says FRGPAAF2 or RAF-2, pause and resolve the conflict through the complete model record. Do not force the PAULTRA2 because it appears close.

Install the new PAULTRA2 correctly

Open the package only after compatibility and physical condition are confirmed. Keep the filter clean and dry. Follow any airflow arrow, printed face, tabs, or holder alignment shown in the manual. Seat the media flat, return the holder if the design uses one, and close the cover until it is normally retained.

The cover should sit as it did before removal. A bowed cover, pinched edge, rattling filter, or latch that needs excessive pressure is evidence to stop and recheck orientation. Never trim the filter, compress its frame, remove a tab, or tape the housing shut. “Almost fits” is not compatibility.

Restore shelves and food without blocking the air inlet or outlet. Air must circulate through the system for odor-control media to do its job. A package pressed against the housing can create noise, limit airflow, and make a correct installation seem ineffective.

Reset the air-filter reminder, not the water reminder

After the housing is closed, use the exact model manual’s control sequence. Frigidaire displays vary. Some have a dedicated Air Filter status or reset control; button names and hold times can differ. Reset only after the new PAULTRA2 is installed so the reminder continues to represent real service age.

Air and water reminders are separate maintenance records. Pressing Water Filter reset does not activate PAULTRA2, improve odor control, or prove the air-filter cover is closed. It can instead erase useful timing for the water cartridge. If the display remains due, use the Frigidaire filter-light troubleshooting guide while preserving which indicator is actually involved.

A reset changes an electronic counter or status; it does not test airflow, authenticate the product, or repair a damaged latch. Verify the cover physically and inspect the display again after normal operation.

Verify the result and record it

Listen for any new rattle near the housing and make sure the cover remains flush. Confirm nearby packages do not obstruct a vent. Odor improvement is not always instantaneous, especially if the original source remains in the cabinet. Reinspect drawers, bins, seals, and food packages before blaming a new filter.

Save the refrigerator model, PAULTRA2/PureAir Ultra II, ASIN B07LD37KTF, purchase source, installation date, and reset result in the Frigidaire refrigerator hub. Set the next six-month reminder from the actual installation date. Add an earlier buying notice if delivery timing matters, but verify compatibility again before opening a stored spare.

Keep unused filters sealed, clean, dry, and away from household chemicals. Do not write only “Frigidaire air filter” in the record; that loses the distinction that prevents a future RAF-2 mix-up.

Final Verdict

A correct PAULTRA2 replacement is a model-verified, no-tool maintenance task: preserve the PureAir Ultra II identity, install the clean filter in the documented orientation, close the housing without force, and reset only the air reminder. Use six months as Frigidaire’s routine interval, but clean actual odor sources and respond to household conditions. The best proof of a successful change is a secure cover, clear airflow, the correct status reset, and a record that says PAULTRA2—not merely “air filter.”
