My filter loop in scala doesn't work?

for(i <- data){
        if(i != 'a' || i != 'e' || i != 'i' || i != 'o' || i != 'u'){
            myArray(i) = i;
            println(myArray(i));
        }
    }

Data is a passed in string, and myArray variable is a char array. Why is it that when the char selected is in-putted into myArray it can be a vowel? Please help, thanks.
