                }
            ), toArray()
        ).subscribe(data => {}

If I correctly understood you, you want to filter products array using if some of the condition in filter array is matched and this filter array may change over the time.
First of all, you should use map operator to modify products stream. And inside map operator you have to filter products which pass the condition.

this.products$
      .pipe(
        map((products) => {
          return products.filter((product) => {
            return this.filters.some((filter) => this.isProductMeetFilterConditions(product, filter))
          })
        })
      )

private isProductMeetFilterConditions(product: Product, filter: Filter): boolean {
    return filter.values.some((value) => {
      return product[filter.key].includes(value)
    })
  }

I have implemented it here, you can open console and see filtered results
