Guide to Water Filters

2019-10-28Tags:Water Filters Supplier, China,Posted By zhaozhao

Water is essential, but it can be dangerous if it is mixed with hazardous chemicals. Even unfiltered tap water is safe to drink, but its taste or smell is poor and may cause illness.


A premium water filter eliminates most of the disease risks associated with tap water and makes it taste better. Installation is easy, but because you have to choose from multiple types, choosing a suitable filter can be a daunting task. Fortunately, once you understand the main filter types and their applications, the selection process becomes much easier.


Activated carbon water filter

The most common type of household water filter is an activated carbon water filter. These filters are filled with charcoal particles made of a high carbon content combustion material such as wood and peat. Charcoal is subjected to a variety of physical and chemical treatments to activate carbon, increase surface area and form macropores.

The activated carbon filter acts by absorption. Large pores and a wide surface area draw particles and chemical contaminants out of the water during filtration. Absorption is a good way to clean water with poor taste or odor.


Reverse osm

Reverse osmosis is often used as the final step in the cleaning process, rather than as a separate filter. Once the water has been removed by other filters, it will be sent to the semi-permeable membrane. Through the reverse osmosis process, water is pushed through the membrane under high pressure, capturing most of the residual contaminants left by previous filters. Reverse osmosis filters work because they work only by water pressure, not electricity, but this process does waste some water.


Ultraviolet filter

This is a type of water filter that was recently created. Ultraviolet filters use the power of ultraviolet light to kill 99.99% of the microbes in the water. This is an environmentally friendly method of water filtration because it does not use any chemicals or heat to remove contaminants from the water. However, UV filters do not have the ability to filter out particles or deposits, and unless the water is free of debris, it is not effective to kill the largest number of bacteria. As with reverse osmosis, UV filters should be the last step in clean water.


Infrared filter

If you live in a place with hard water, the IR filter is one of your best choices. Infrared filters use heat and light to negatively charged molecules in hard water. As a result, the water becomes softer and bacteria, excess minerals and other impurities are removed.


Ion exchange filter

Another great way to soften hard water is to use an ion-exchange filter. Water hardens due to the accumulation of magnesium and calcium ions. The ion exchange filter extracts these ions from the water and replaces them with sodium or hydrogen ions. The ion exchange process effectively softens water, removes excess minerals and bacteria, and improves taste and odor.

Ion exchange filters are generally not used for drinking because sodium levels may be unhealthy or unpleasant, but they are very useful for continuous high-temperature applications such as cooking, laundry and commercial grade coffee machines.


in conclusion

All of these filtering options are beneficial in a variety of ways, but they are almost always combined to make the best use. Water filtration systems for residential and commercial buildings typically have two or more different filters to purify water as efficiently as possible. Which system works best depends on the local water source and the main use of the water. Now that you have the most common filter knowledge, you can create the right water filtration system for your home or business.
