Frigidaire PureAir Ultra II Air Filters: Performance and Installation Guide

Strong leftovers can turn your fridge into a smell zone overnight. Frigidaire's PureAir Ultra II (part PAULTRA2) steps in with carbon tech to trap those odours and keep air cleaner.

This filter fits newer Frigidaire Gallery and Professional models, using activated carbon – sometimes mixed with baking soda and zeolites – to handle a wide range of smells. Users often notice the difference quickly, especially in busy kitchens. I've seen plenty of feedback over years writing for filter shops, and this one gets praise for outperforming simple baking soda setups.

Key Specs and Performance

The PureAir Ultra II measures about 3.8 inches by 1.8 inches, compact enough to slot in without fuss. It relies on carbon to adsorb odour molecules, pulling them out of circulation.

Performance stands out for everyday use. It appears to cut strong smells like garlic or fish effectively, with many saying it beats baking soda by a good margin. In humid spots, it might need earlier swaps, but overall it keeps food tasting neutral longer.

One subtle point: generics can match closely for less money, though originals ensure exact fit and consistent quality.

Lifespan and When to Replace

Frigidaire recommends changing every six months for best results. Some packs cover a full year with two filters.

Signs it's time include returning odours or a reminder light on the panel. Heavy use – think big families or lots of pungent foods – shortens that to four or five months sometimes.

Sticking to schedule helps maintain airflow and freshness. Skip it, and bacteria or gases build up again.

Model Compatibility

This filter works with select Frigidaire and some Electrolux models, mainly Gallery and Professional lines like French-door or side-by-side setups.

Common fits include:

• FGHB2868 series
• FGSC2335TF
• FPBC2278UF
• Similar Gallery French-door units

Check your manual or the packaging list for exact matches. Newer models with PureAir systems need this specific PAULTRA2 – older ones used different parts.

Not universal, so double-check to avoid poor seating.

Installation Steps

Swapping takes minutes, no tools needed.

1. Locate the slot – often top right in the fresh food section or rear grille.
2. Remove plastic wrap from the new filter.
3. Pull or twist out the old one gently.
4. Slide or twist the new one in until it clicks.
5. Reset the filter light if your model has one (hold the button usually).

That's it. Air cycles fresh soon after. For Frigidaire owners managing both water and air quality, pairing replacements makes sense, as explained in How to replace Frigidaire PureSource water and PureAir filters together. 

Competitors and Alternatives

Whirlpool's FreshFlow targets ethylene more, which helps extend produce life. GE's ODORFILTER keeps the basics covered at a lower price point. LG adds antimicrobials in some models for mould-prone kitchens. Sub-Zero goes premium with longer-life cartridges built for luxury systems.

Generics from Tier1 or Mist offer similar carbon performance at a lower cost, especially when bought in multi-packs. Frigidaire originals still stand out for seamless fit and consistent odour control within their own ecosystem, a key point highlighted in The Ultimate Guide to Refrigerator Air Filters.

Wrapping Up

Frigidaire PureAir Ultra II delivers reliable performance with easy installation, a six-month lifespan, and model-specific compatibility. Its activated carbon design traps odours effectively and keeps the fridge smelling clean.
