There are several types of water filtration systems available. Choose the system that meets your needs based upon the contaminants you’re trying to remove. Be aware that although the countertop water filters are easiest to install initially, they’re more bulky and less convenient than the hidden undersink water filters. They’re also less versatile if you’re attempting to filter contaminants other than tastes, smells and lead.
Whole-House Water Filters: Whole-house water filters are available and easy to install. They’re placed in the main water line entering your home and are designed to remove sediment and rust particles from all of the water entering your home. They can also benefit the other types of water filters by acting as a particulate prefilter.
Undersink Water Filters: Different varieties of undersink filters are available and should be chosen depending upon your home’s individual needs. Some of these filters remove bad tastes and odors only. Others also may remove lead, bacteria and sediment or any combination of the four. These units may have multiple cartridges, each designed to filter a particular type of contaminant.
Undersink water filters are convenient because, once installed, you don’t even know they are there. Turn on the water and filtered water comes straight from the faucet. They’re also efficient because they allow you to filter only the water going to a specific faucet, thereby reducing the demands on the filter cartridges. You don’t need to filter your bath water to remove a chlorine taste, for example, but you may want to remove it from your drinking water. Undersink water filters are also helpful if your plumbing is joined with lead solder. By being in line immediately before the faucet, undersink water filters provide maximum filtration protection.
Countertop or Canisters water Filters: These are the simplest water filters available. They’re countertop appliances, like toasters, and can filter drinking water for different contaminants. Unlike undersink water filters, their use isn’t transparent. Some of these filters must remain on your counter. Others require connection to your spigot and some require that water be poured through them, much like a drip coffee maker.
