Tea Filter PacksTea Filter packs are a convenient way to brew iced tea in larger quantities. We have a number of great selections of iced tea, in both regular and flavored varieties. Filter packs are a great choice if you're brewing tea for your Church, Sandwich shop or other large scale tea needs. Be sure to take a look at our tea brewers to compliment our filter packs. Generally use a 1-ounce large tea bag filter pack per gallon of pure water for ideal iced tea.
