There are now EGO3 filters for all whirlpool brands.
There are two basic systems:
1 - Toploader: Your previous filter is mounted in a shaft (with or without thread)
2 - Standard assembly: Your filter is simply screwed on free-standing
For variant 1, this always fits EGO3 whirlpool filter model Toploader no matter how long or short your previous filter was. Regardless of whether it has a thread at the bottom, a bayonet lock or just an opening. It doesn't matter if the diameter is smaller. The EGO3 toploader filter always fits.
For variant 2 you only have to measure the thread diameter, whether it is a 2 inch or 1 3/4 inch thread diameter. And check whether you have a coarse or fine thread. There are 4 combinations.
