I recommend using a Swissgold filter with the appropriate plastic cone. And prior to pouring water thru my pourover setup, I measure water temperature using a tea brewing thermometer made my TelTru. Since you inquired, coffee should brew between 198-205F and a brewing temperature difference (not to mention grind setting) as little as 1 degree F either way can make or break the flavor of the final brew.
