Hard to understand your question.. But maybe this will help:

@Pipe({
  name: 'productFilter'
})

export class ProductFilterPipe implements PipeTransform {
   transform(value: IProduct[], filter: string): IProduct[] {
      filter = filter ? filter.toLocaleLowerCase() : '';
      return filter && value ?
        value.filter(product =>
           (product.productName.toLocaleLowerCase().indexOf(filter) !== -1) ||
           (product.??npmName??.toLocaleLowerCase().indexOf(filter) !== -1)
        ) :
        value;
   }
}
