The under counter water filter
The under counter type of water filter is the unit we will be discussing in this website because it provides better performance and lower long term cost than other filters, even considering the cost of installation. This unit filters a lot of water and instead of cluttering the counter, it utilizes space from the cabinet beneath the sink. Depending on the installer's ability, it can be personally installed or may require professional plumbing modifications. It does require a third hole for the faucet, or dispenser, which is usually provided by removing the spray attachment included in most home sinks. If a third hole is not available, you will have to drill a hole for the dispenser through the sink or countertop. Most homeowners have the ability to perform these steps. This site provides a video which shows the proper installation of under counter units.
We have researched several makers of water filters using the website WaterFilterComparisons.com. We found the best unit on the market, considering features and long term cost, to be the Aquasana AQ-5300.55 Under Counter Water Filter System. This unit uses simple screw-on plumbing connections which makes installation by the homeowner much easier. The unit also contains an electronic indicator to let you know when it's time to change the replaceable filter.
This unit uses a three stage filter to remove chlorine, lead, mercury, rust, silt and a large list of chemical pollutants. The filter does allow safe minerals to pass through, providing good tasting water. The filters last approximately six months and filter around 600 gallons of water. This makes the cost of each gallon of filtered water to be around ten cents, far cheaper than bottled water.
