Since it is apparent, you want to remove all words that contain a number, because in your example mm is also gone, because it is prefixed by a number.

val s = "That's 22m, which  is gr8."
s.split(" ").filterNot(_.exists(_.isDigit)).mkString(" ")

res8: String = That's which  is

Please, try filter or filterNot

val text = "canon 40 22mm lens lock strength plenty orientation 321 ."
val without_digits = text.filter(!_.isDigit)

or

val text = "canon 40 22mm lens lock strength plenty orientation 321 ."
val without_digits = text.filterNot(_.isDigit)
