Water, water everywhere, but does it matter how you get the drops you drink? Yes! If you’re drinking the recommended eight glasses a day, then a family of four will go through 730 gallons a year in drinking water alone. That comes to around 5,800 half liter bottles of water per year if you’re buying your H20 prepackaged. It’s expensive and it's wasteful. It's alo not particularly good for your back to be constantly hauling bulky flats of bottled water out of your car and into your house.Not everybody can stomach tap water “as-is”, though. Depending on your local water system,the liquid coming out of the faucet could be over-chlorinated,rusty, or smelly with sulfur. It could even contaminated with lead, pharmaceuticals or dangerous microorganisms. People who want to enjoy the best of both worlds filter their affordable tap water at home. The savviest consumers of them all know how to buy great water filters at an affordable price.I’ve researched the best discount water filters that are widely available on the market today. These are the ones that have floated to the top of the pool. PUR 18 Cup Water Filter Dispenser This workhorse from long-time filtration leader PUR is one of the best-selling water filters on the market today. This is a great filter for busy families. Its large, 18-cup tank ensures that everyone gets a glass when the crew rolls in from soccer practice, or the scout troop is meeting at your house. Even better, the slim profile uses precious fridge space wisely. It uses only minimal amounts of prime, front-of-shelf space, with no room wasted on a bulky plastic handle. The simple pour spigot makes for easy operation even by young children. It's also great for adults with arthritis, carpal tunnel syndrome, or other conditions that can make stabilizing a heavy pitcher a chore.This dispenser also receives solid marks for its high capacity, low cost filter cartridges. PUR’s cartridges use carbon sustainably sourced from coconut shells. Each cartridge can filter 40 gallons of water, and name-brand replacements cost less than $10 per unit.

Just turn on the faucet, twist on the filter, and fill your glass in seconds. When the filter needs changing, a light will go off, alerting the consumer that it’s time for a replacement.The MineralClear filter cartridges used by this product are also a great value. Each one filters up to 100 gallons of water at a cost of less than $10 each. Bear in mind, though, that some buyers have had complaints about this filter’s longevity.

The Life Straw is lightweight and designed to filter out the dangerous microorganisms that can turn a fun weekend on the trail into a life-threatening visit to the hospital. The Life Straw filter does not correct for minerals dissolved in water that may leave an unsavory taste.
