Is a water filter effective?

Filters can remove tons of contaminants from your water, but they're not 100% effective. Just because a filter removes 1 contaminant doesn't mean it also removes others. It pays to do your research and be diligent in choosing the best water filter for your needs. Check brand claims and read the fine print on the packaging to ensure the filter will work for your purpose.

How often should I change my water filter?

Experts recommend changing an under sink or benchtop water filter after 6 to 12 months. Replace water filters in jugs and bottles after every 40 gallons or every 2 months, whichever comes first. Replace filters in water filter dispensers after 8–12 months.

What is the difference between under sink filters and faucet filters?

Under sink water filters are installed under the sink and send water through a pipe. It also uses its specific faucet. This system helps filter large amounts of water and doesn't take up counter space. However, it's expensive and requires modifications to plumbing, which can be equally costly. Faucet filters are made with built-in filters that are then installed in your kitchen sink. It allows you to switch between filtered and unfiltered water with ease. It's also expensive and requires expert help for installation.

What treatment devices do water filters have?

Water filter systems may have activated carbon filters, an ion exchange unit, a reverse osmosis unit or a distillation unit. Activated carbon filters remove organic contaminants, cleaning solvents, pesticides and chlorination by-products. An ion exchange unit removes minerals, radium, barium and even fluoride. A reverse osmosis unit filters out nitrate, sodium, odours, and foul taste. A distillation unit helps remove nitrate, bacteria, hardness and most organic compounds.
