Same dimensions as EF108WArvosana 5/5
EF114 is only 1mm longer and wider than EF108W HEPA H13 filter. But it has 130 ribs while EF108W has only 103. So EF114 has 30% more surface area.
They also both seem to be made from same material (through visual inspection). So I do not understand why EF114 can't be washed. Perhaps it can be washed? I wonder if electrolux figured out 3 year filter change interval is not good for their profit margins? :)
