Frigidaire PureAir Air Filter FRGPAAF2 (AF-2 / RAF-2): When to Replace It & Which Fridges Use It
Your fridge water filter has a light that turns red. Your air filter does not. So the Frigidaire FRGPAAF2 (also called AF-2 or RAF-2) is one of the easiest filters to forget. It just quietly stops working. Most people only notice when their food starts to smell or goes bad too fast.
This guide keeps it simple. First, a quick check to see if your filter is already too old. Then everything else — what the names mean, which fridges use it, how it’s different from the AF-1, and when to swap it.

If any of the first five match your fridge, your FRGPAAF2 is done. Time for a fresh one. Keep reading to make sure you order the right filter.
What Is the Frigidaire FRGPAAF2 (AF-2 / RAF-2)?
The FRGPAAF2 is a genuine Frigidaire air filter from the PureAir line. It’s the second version of Frigidaire’s fridge air filter. Inside it is activated carbon, which soaks up bad smells and gas from the air in your fridge.
It needs no batteries and no button. You just slide it into its slot. As long as your fridge fan runs, air keeps passing through the filter — so it cleans the air all day, every day.

Why Does It Have Three Names?
This confuses a lot of people. The same filter is sold under three names. Here’s the simple version.
| Name | What It Really Is |
|---|---|
| FRGPAAF2 | The official Frigidaire part number (in your manual) |
| AF-2 | Short name printed on the filter itself |
| RAF-2 | The name shops use on the box and online |
All three are the same filter. If you see any of them on your old filter or in your manual, the FRGPAAF2 is your replacement.
How Does It Remove Smells?
The carbon inside the filter is full of tiny holes — so many that its surface is huge. When smelly air passes through, the smell molecules stick to the carbon and stay trapped. This is why a good filter really removes smells instead of just hiding them.
After about 6 months, the carbon fills up. There’s no more room for new smells to stick. That’s when odors come back and food starts smelling off. Worse, a full filter can even start letting old trapped smells back into the air. So changing it on time actually matters.
Which Frigidaire Fridges Use the AF-2?
The FRGPAAF2 fits many newer Frigidaire and Electrolux fridges that use the AF-2 / RAF-2 slot. Some common models include:
- Frigidaire: FGHB2866PF, FGHB2869LF, FGHB2878LF, FGHD2368TF, FGHD2373NF, FGHF2366PF, FGHF2369MF, FGHC2331PF, FGHC2344KF, FPHB2899LF
- Electrolux: EW28BS71IS, EW28BS85KS, EW23BC87SS, EI23BC82SS, EI26SS55GB, EW23CS85KS, EI28BS55IS, EI28BS65KS, EW36SC55GS, EI26SS30JS
Easiest way to be sure: look at the label inside your air filter slot, or read your current filter. It will say AF-2 (or RAF-2). If it does, this is your filter.
AF-2 vs AF-1: Don’t Mix These Up
The AF-2 and AF-1 look almost the same and both say PureAir. But they are not the same filter and they do not swap.
| AF-2 (FRGPAAF2) | AF-1 (FRGPAAF1) | |
|---|---|---|
| Version | 2nd (newer fridges) | 1st (older fridges) |
| Also called | RAF-2 | RAF-1 |
| Life | 6 months | 6 months |
| Swaps with the other? | No | No |
| How to know | Label says AF-2 | Label says AF-1 |
The safest check is to read your old filter. If it says AF-2, order the FRGPAAF2. If it says AF-1, order the FRGPAAF1. Don’t guess by the year of your fridge — Frigidaire switched over slowly, so the year isn’t reliable. Ordering the wrong one is the #1 mistake here.
When to Replace It (Keep It Simple)
You don’t need a fancy schedule. Just follow this:
- Change it every 6 months — no matter what.
- Change it sooner if you smell anything or food is spoiling fast.
- An easy trick: change it twice a year — spring and fall. Easy to remember, and it keeps your fridge fresh through summer cooking and the holidays.
Set a reminder on your phone for 6 months from the day you install a new one. Done.
What Happens If You Wait Too Long
Skipping the change to save a few dollars usually costs you more:
- More wasted food. A full filter lets gas build up, so fruits and veggies spoil faster. One week of spoiled groceries can cost more than the filter itself.
- Smell spreads to other food. Strong foods like fish, onions, and cheese pass their smell to butter, milk, and leftovers. It even changes how they taste.
- It can make smells worse. A completely full filter can push old trapped smells back into the fridge.
A fresh filter is cheap. Wasted food and ruined leftovers are not.
