A water filter is a device used to reduce contaminants in drinking or cooking water. There are several types of water filters, and each is designed for a specific purpose. They are made of many materials and use a variety of techniques to remove impurities from the water. Some water filters remove only certain contaminants, while others remove virtually everything.
Physical Filtration (Adsorption/Activated Carbon)
Activated carbon is used in most of the filters on the market today. It is the most common form of adsorption filter and works well for removing chlorine, odors, and chemicals such as pesticides.
Chemical Filtration
There are many chemical filters available on the market, including systems that use potassium permanganate and carbon tetrafluoride. These systems can remove a number of contaminants from your drinking water, including iron, sulfur, and copper.
Resins That Exchange Salt
There is a wide variety of resins that can be used to help remove salt from your drinking water. These include resins that utilise sodium ions, and resins that use hydrogen ions instead of sodium.
These resins are much more efficient at removing large amounts of salt, and they can be used in conjunction with reverse osmosis. Alternatively, there are resins that can be used to remove other contaminants such as calcium, magnesium and sulfur.
Chloramine Removal
A variety of filters can be used to remove chloramines from your water, but only some work as well as others. The most effective ones are those that use a media that is treated to change its electronic structure, causing it to act like a catalyst and speed up the process of releasing chlorine from chloramines.
FloWater is a great example of this type of filter. It is an electric water delivery system that filters the water from several different angles, focusing on reducing bacteria and solids while also removing lingering odors. It can be used for a wide range of purposes, from home and office use to public and private pools.
NSF Certifications
NSF certifications are an important part of a water filter’s effectiveness and are issued by a non-profit organization that works to improve health and safety worldwide. They are issued after a thorough evaluation of a water filter’s performance and safety features, and can give you peace of mind when choosing one.
In addition, a water filter that is NSF certified will often also be backed by an industry group, such as the Water Quality Association or Underwriters Laboratories. Both of these groups have rigorous standards and offer a Gold Seal or NSF certificate to ensure that a product is a good choice for consumers.
If you’re looking for a filtration solution, talk with your local water expert to discuss the best options. Your water expert will be able to determine which contaminants you need to remove, and then provide a recommendation for the most effective filtration system.
Once you’ve determined which contaminant you need to remove, it is time to start shopping for your new water filter. Check with your local retailer to find a system that fits your budget and meets the needs of your family. Wasserfiler
