Using array formula instead of creating a helper column

Hi Excel folks, would appreciate some help on whether I can cut down a step of creating a helper column by using an array formula (or any other method but not VBA)? Currently I'm using a helper column and sumproduct with a double negative (--) (to get a sumproductif formula). However, I'm looking to cut down as many steps as possible because my table is large, and I want to filter it on the go (hence will need a formula that won't mess up when I filter the table). Thanks a million!!
