Under Sink Chlorine Water Filter

There are several clear benefits in installing an under the sink water filter. Compared to countertop water filters and faucet mount water filters, the under sink water filters are more efficient and are capable of purifying water in addition to filtration.

They can remove the regular suspects such as chlorine and sulfur which causes bad odor to your water, a good under counter or under sink water filter can also remove microbial cysts, pharmaceutical chemicals etc from your tap water.

Even though under sink water filters cost more initially, from a unit cost perspective, they are more cost-efficient. They can provide nearly pure water (depending on the technology used) at $.10-$.12 per gallon. Compare this with the cost of buying bottled water.

Under sink water filters will also reduce the clutter on your counter top where often the space is a premium. Additionally all their mechanisms are hidden and are out of the way and beyond the reach from children and careless adults.

There are some disadvantages also for the under sink water filters. Obviously the initial cost is higher compared to countertop or faucet mount filters. Also they require some expertise for installation. If you have below average handyman skills, you would be better of hiring a plumber to install an under sink water filter. This also means that this is a more permanent setup which may not be what an apartment dweller or a renter may like.

The table below will help you to find the right Under Sink or Under Counter Water Filter for your family. You can sort the filters based on price, color, filter life, customer rating etc.
