Frigidaire PureAir FRGPAAF2 Air Filter: When to Replace It and Which Fridges Use It

Your fridge has two filters, not one — and they do completely different jobs. The water filter cleans what comes out of the dispenser. This guide is about the other one: the Frigidaire PureAir FRGPAAF2, an air filter that cleans the air circulating inside the fridge itself. If your refrigerator has started smelling like last week’s leftovers no matter how often you wipe the shelves, this small carbon cartridge — not the water filter — is almost certainly the part that is finished.

First: This Is an Air Filter, Not a Water Filter

The distinction matters because the two get confused constantly, and ordering the wrong one helps nobody. The FRGPAAF2 does not touch your drinking water at all. It sits in a small housing inside the fresh-food compartment and filters the air as it circulates past your food. Its job is odour control and freshness. The water side of a Frigidaire fridge is handled by a separate cartridge — on most current models that is the PurePour PWF-1 water filter, part FPPWFU01, covered in our complete FPPWFU01 guide. Many Frigidaire owners need both, on roughly the same six-month rhythm.

What the FRGPAAF2 Actually Does

Inside the cartridge is an activated carbon block. As the fridge’s fan moves air through it, the carbon captures and locks away the compounds that make a refrigerator smell stale:

• Food odours — the product page calls out onions, garlic, fish and leftovers by name. Trapping them stops smells migrating between foods, so milk, butter and open ingredients keep their own flavour instead of borrowing the fish’s.
• The elements that speed up spoilage — the page describes the filter as continuously purifying the internal airflow and neutralising elements that accelerate food spoilage, which helps fresh fruit and vegetables stay crisp and colourful for longer.
• Stale, stagnant air — Frigidaire positions the carbon block as far more effective than the traditional open box of baking soda, because the air is actively pushed through the carbon instead of drifting past it.

It does all of this passively — the page’s specification lists the power source as “None”. No wiring, no batteries; the fridge’s own airflow does the work.

FRGPAAF2, AF-2, RAF-2: Three Names, One Filter

This is the part of the old naming maze worth clearing up, because owners search under all three names. The product page states it directly: this is the “Frigidaire PureAir RAF-2 Refrigerator Air Filter (also known as AF-2 or Part Number: FRGPAAF2)”. In other words:

• FRGPAAF2 is the current part number to order by.
• RAF-2 and AF-2 are the PureAir model names for the same cartridge — if your manual or your old filter says PureAir AF-2 or RAF-2, the FRGPAAF2 is your replacement.
• The page’s comparable part numbers also list ELXPAAF2 and CWFF417 as cross-references for the same filter.

One honest limit: names only go so far. If the cartridge you pull out carries a number that appears nowhere in that list, do not force the match — compare its shape and size against the dimensions below, and treat the label on the old filter as the final authority, as with every filter we sell.

Which Fridges Use the FRGPAAF2?

Per the product page, the FRGPAAF2 fits Frigidaire and Electrolux refrigerators with the built-in PureAir air filter housing (the page’s compatibility data also lists Kenmore-branded refrigerators built on the same platform). Its compatible-model list runs to more than twenty model numbers, including:

• Frigidaire: FRFC2323AS, FRFC232LAF, FRFC233LAF, FRFG2323AF, FRFG232LAF, FRFN2823AS, FRFS2823AD, FRFS2823AS, FRFS2823AW, FRFS282LAF
• Electrolux: ERFC2393AS, ERFG2393AS
• Frigidaire Gallery / Professional families on the same list: GRFC2353AD, GRFC2353AF, GRFG2353AF, GRFN2853AF, GRFS2853AF, PRFC2383AF, PRFG2383AF, PRFS2883AF

If your model is not in that selection, check the full list on the FRGPAAF2 product page — and again, the label on the cartridge you remove settles the question in ten seconds.

When Should You Replace It?

Frigidaire’s guidance on the product page is unambiguous: replace every 6 months to maintain optimal freshness, and the filter’s rated life is 6 months. An air filter gives you clearer warnings than a water filter does, because you can smell its failure:

• Fridge odours come back within a day or two of cleaning
• Strong foods start flavouring everything stored near them
• Produce in the crisper seems to tire faster than it used to
• It has simply been more than six months — carbon saturates on schedule whether it smells finished or not

Once the carbon is saturated it cannot capture anything further; the cartridge is still sitting in the housing, but it has stopped doing the job. Six months is the outer limit, not a target to stretch.

Where It Sits and How to Swap It

The housing is inside the fresh-food compartment — a small compartment with a cover, positioned so the fridge’s airflow passes through the cartridge. Frigidaire designed the swap to take under a minute, with no tools:

1. Open the refrigerator’s air filter compartment cover.
2. Pull out the old, exhausted cartridge.
3. Snap the fresh FRGPAAF2 into place and close the cover.

That is the entire procedure. No water shut-off (it is an air filter — there is no water line involved), no reset button sequence to memorise for the filter itself. If your model has an indicator for the air filter, your manual’s reset step applies, but the physical change is the three steps above.

FRGPAAF2 Specifications

All figures below are taken from the product page:

Genuine vs Generic Air Filters

The product page makes the genuine case in fit terms: this is a genuine OEM replacement built to exact factory specifications to slide into the built-in housing, while cheap aftermarket replicas use low-grade carbon flakes and can leave gaps around the cartridge. For an air filter, gaps are the whole story — air takes the easiest path, and air that slips around the carbon instead of through it comes out unfiltered. The genuine cartridge is also a carbon block, not loose flakes, which is what gives it the surface area to keep working for the full six months. At this price point, the saving on an uncertified copy buys very little and risks the one thing the part exists to do.

Price, Packs, Shipping and Returns

The genuine FRGPAAF2 is $15.99–$51.99 at Discounted Filter Store depending on pack size — 1, 2, 3 or 4 packs, with the per-filter price dropping as the pack grows. Given the six-month interval, a 2-pack is a full year of freshness bought once. Orders are processed within 1–2 business days and delivered in 3–5 business days via USPS, with free US shipping on any order amount. Ordered the wrong filter? Unopened filters can be returned within 30 days, free, with a prepaid label.

Ready when you are: order the genuine FRGPAAF2 PureAir air filter — and if the cartridge you pulled out carries a number you do not recognise, send it to us before ordering and we will confirm the match.

Frequently Asked Questions

Is the FRGPAAF2 a water filter? No. The FRGPAAF2 is a refrigerator air filter — it cleans the air inside the fridge to control odours and keep produce fresh. Your drinking water is handled by a separate water filter (on most current Frigidaire models, the FPPWFU01 / PurePour PWF-1).

Are FRGPAAF2, AF-2 and RAF-2 the same filter? Yes. The product page describes the part as the PureAir RAF-2, also known as AF-2, with part number FRGPAAF2. ELXPAAF2 and CWFF417 are also listed as comparable numbers for the same cartridge.

How often do I change the FRGPAAF2? Every 6 months — that is both Frigidaire’s recommendation on the product page and the filter’s rated life. Replace sooner if fridge odours return despite cleaning.

Where is the air filter in my Frigidaire fridge? Inside the fresh-food compartment, in a small covered housing positioned in the airflow path. Open the compartment cover, pull the old cartridge out, and snap the new one in — under a minute, no tools.

Which brands does the FRGPAAF2 fit? Frigidaire and Electrolux refrigerators with the PureAir air filter housing — the product page’s list runs to more than twenty models, and also includes Kenmore-branded models built on the same platform. The label on your old cartridge is the final check.

How much does the genuine FRGPAAF2 cost here? $15.99–$51.99 depending on pack size (1 to 4 packs), with free US shipping on any order amount and free 30-day returns on unopened filters.
