Brita’s water filters are one of the most popular ways of purifying water at home, but they’re expensive and sometimes hard to find. However, I was able to find a pack of 3 for only $16.99 at Amazon.com. The filters produce water that tastes just as good as the bottled stuff, but at a much lower price. They will remove a variety of impurities, and make the water taste more refreshing. The filters should be changed every two months or 40 gallons (whichever comes first).

Get them at Amazon.
