Hey there! Does your over-the-range microwave smell like last week's dinner every time you turn it on? The charcoal filter is probably shot. This 2-pack is an affordable, high-quality replacement that's compatible with a bunch of Whirlpool and KitchenAid microwave models (like those with YWML, YML, KMLS codes). It directly replaces part numbers W11322423 and W11284565. These are activated carbon filters – that's the stuff that actually traps cooking odors, grease fumes, and smoke before the air gets recirculated back into your kitchen. Swapping it out is usually pretty easy (check your manual) and makes a huge difference in keeping your kitchen air fresh. We recommend changing these filters every 6 to 12 months, depending on how much you cook. This 2-pack gives you a spare so you're always ready. Stop putting up with stale smells and get your microwave venting like new again. Just make sure to double-check your model number before ordering to ensure a perfect fit!
