How to choose the right water filter
Aug 21, 2018

Water filtering systems can be defined into two forms, one is whole house/ point-of-entry (POE), one is point-of-use (POU). Whole house/ point-of-entry (POE) including whole-house filtration, point-of-use (POU) including water pitchers, countertop faucets and under-the-sink systems. Whenever possible, a whole house system is the best choice for health, so that there are no chemicals absorbed through the skin when showering or washing hands.

Customers should choose which filtering technology they prefer (some use multiple) instead of focusing on the brand name itself. Each technology can also vary in quality and how well it removes every contaminant.

 

So firstly, customers should find out what’s contaminating their water. This will help customers decide if they need to target any specific contaminants when choosing a filtering system. The information is available on the local government website or newspaper. Visible particles in the water can be rust or sediment, and houses that rely on wells often have bacteria in the water. The contaminates the water has will depend on customers’ home.

 

Then customers should evaluate their specific water filtration needs based on the contaminants in their water and the POE and POU systems. If the contaminates in the water are very toxic, customers probably want a POE filter to clean all the coming into their house water. POE systems treat all of the water that enters the home and connects to the water meter. POE filters can be attached externally or can be installed inline.

 

On the other hand, if customers are only filtering the water for taste, a POU filter on the faucet will suffice. POU systems treat water at the point where it is being consumed, such as a shower head or sink. POU filters can be mounted to a faucet, under the sink, or the countertop. POU filters that are installed inline purify all the water passing through a pipe.

After evaluating customers’ water needs, the next step is buying the right home waer filter. It is suggested that pick a filter certified by an accredited certification body (examples: NSF or WQA Gold Seal) and is designed to reduce the contaminants found. Without an accredited certification, there is a risk in quanlity of water filter.

Maintenance costs is an important consideration when customers choose a water filter. Filter cartridges need to be periodically replaced to function properly, and the cost of replacing a filter cartridge can range from $20 to $400. Choose a filter that is can be afforded to maintain. If the filter is used and do not change the cartridge when it is supposed to be replaced, the water will not be clean anymore. Use a calendar or other reminder to keep track of when filter cartridges are needed to be changed. Also it is more convinient to purchase extra filter cartridges.

Install the filter according to the manufacturer’s instructions. Many POE and POU systems will be easy to install, but customers can also hire a professional to install the filter. Some POU filters are required to run some water through the filter before consuming the water. Read and follow all of the manufacturer’s instructions when installing the filter.
