How Do Water Filters Work and When Should You Change Them?
Water Filters are invaluable when it comes to giving you clean and safe water to use, but how would you know if they can't do their job anymore? Water filters come in different types and sizes, that can fit every household's needs. Each water filter can provide you with the maximum filtering technology when in the right condition. However, many of you might ask

How often should you change your water filter cartridges?

Generally, replacing water filters depend on its usage. If you live alone, then you probably have the maximum life span of every cartridge, which is 1 year. If you live with your family (up to five), you will find your household may use more water than average. How often you change water filter cartridges depends largely on water quality and the frequency of water use. My Water Filter products use different filtering systems specifically for showers, tap water and even for the whole house. This way, you are guaranteed to enjoy clean and safe water for you and your family.

The Way Water Filters Work

The technology behind water filters is simple- it acts as a physical blockade that traps unwanted particles in your water. However, water comes from different sources which means different particles could be present. To effectively eliminate different waterborne contaminants that may cause illness, various water filter technologies have been developed.
  • Activated Carbon
'Activated Carbon' works by absorbing contaminants trapped inside the pore structure of the carbon filter. There are two types of this filter, the 'Carbon Block' and the 'Granulated Activated Carbon' filter where both are dependent on water pressure. The Purity Series Water Filters from My Water Filter utilises both types. Generally included in one of several stages of water filtration in most systems, which functions to remove chlorine, taste and odour in your drinking water. However, it cannot filter inorganic pollutants like fluoride, arsenic and nitrate.


  • Reverse Osmosis

This water filter system contains more advanced technology than the 'Activated Carbon' because it can remove fluoride, arsenic and nitrate. Thus, these types of filters are recommended for people who want to remove fluoride or may have an illness. The Purity Series 3 Water Filter from My Water Filter undergoes 5 stages of purification where reverse osmosis is part of it.


  • Ultra Violet
This water filter technology kills unseen bacteria. The Purity Series 4 Under Sink and Purity Series 5UV Whole House Water Filters have this technology where each UV light can last 1 year.



Changing Water Filters
