There are some factors to keep in mind when it comes to choosing a water filter system. People should consider a water purification/filter system that conforms to the quality standards implemented by the EPA as and meets their particular needs. Not all systems can eliminate every contaminant. If they have a problem regarding a particular contaminant such as bacteria or radon, it is best to decide on a water filter system that is known to remove that contaminant from their supply.
There are two types of water purification systems: point of use (POU), in which the water is filtered at the faucet where it is attached and point of entry (POE), wherein it is filtered when it enters the home to have purified water at all faucets. The latter can sometimes include a filter traps contaminants such as microbes and chemicals found in the water or eliminates contaminants in other ways.
Point of Entry Water Filters come with:
- Water softeners
These devices correct water hardness using an exchange system. Calcium and magnesium that are present in tap water can make it hard. Using sodium or potassium ions, this filter replaces calcium and magnesium ions to make the water softer.
This system uses jets of air to remove some chemicals, including radon and gasoline’s chemical components.
- Water filtration or adsorptive media
These are usually carbon-based filtering systems that capture solids and liquids in the filter.
Point-of-Use Water Filter come with
These devices work by boiling water then removing the vapor containing contaminants. While this process removes a lot of the minerals that are often found in tap water, it may change its taste.
- Reverse osmosis units
Such devices filter water by means of a membrane, using pressure to pull out chemicals and microbes. Though this system uses lots of water,they eliminate all the chemicals as well as microbes that cause diseases. This makes it a very effective purification method.
- Filtered water pitchers
Systems such as this include a replaceable filter (good for 3 months) that captures chemicals plus other contaminants. First, the pitcher is filled with water from the tap then this flows out through the filter. This affordable, simple-to-use system can improve the taste of tap water.
Water Filter Options
Those who are not ready to install a purification system can choose other ways to address some if not all their drinking water issues even if they do not have a filter.
- When turning on the water after a couple of hours, they should let the cold water run for several minutes to flush other lead present.
- Then they need to boil the water for 1 to 3 minutes, cool the water then place it in a clean pitcher before putting it inside the refrigerator. This way, microbes such as cryptosporidium will be eliminated.
- They can also put tap water inside a pitcher or other container then refrigerate it to help improve the taste of water that has too much chlorine.
When water safety is a concern, people can take the necessary steps to improve the quality of water in a home so that they will feel at ease knowing that the water is safe to consume. The moment they determine the issues that need to be solved, they can decide on the system that best suits them to improve their water quality.
