Hey Frigidaire owners! If your fridge is starting to smell a little funky or you're getting that 'fridge smell' in your food, it's probably time to replace your air filter. This 4-pack is perfect because you'll have replacements ready to go for the next couple years (they recommend changing every 6 months). These filters are compatible with Frigidaire Pure Air Ultra II, Paultra2, and Electrolux models - they work with part numbers 242047805, 5303918847, EAP12364179 and tons more. The filters use premium coconut shell activated carbon which is seriously effective at absorbing odors and keeping your fridge smelling fresh. Installation is literally a 30-second job - no tools needed, just pop out the old one and slide in the new. The package even includes a little cleaning brush to tidy up the compartment while you're at it. I've been using these in my Frigidaire for a couple years now and they work just as well as the expensive OEM filters but cost way less per filter. They really make a difference in keeping your food from tasting like 'refrigerator' - you know that weird taste things get when odors mix? Yeah, these eliminate that completely. Having four on hand means you'll never have to run to the store last minute when your fridge starts smelling. Seriously, if you haven't changed your fridge filter in a while, your nose will thank you for grabbing these!
