Water filters remove unwanted impurities from water such as sediment, taste, odor, hardness and bacteria to result in better quality water. However, even the best water filter won’t do you any good if you don’t replace the filter cartridge regularly. Water filter cartridges come in many sizes and shapes, but all are designed to do specific tasks in water filtration. At EAGO, whether you need a carbon filter, a sediment filter, or filter to remove fluoride from your water, we have a wide range of replacement water filter cartridges to fit all types of standard systems.
Reverse Osmosis Purifiers
A typical RO purifier consists of four filters in series plus a storage tank. The first is a sediment filter, the second a carbon block, the third a membrane and the fourth an activated carbon block to remove any remaining chlorine by-products. Such a system removes a wide spectrum of impurities from water.
Reverse osmosis effectively removes turbidity, sediment, colloidal clays, total dissolved solids, toxic metals, radioactive elements, pesticides, and herbicides. This can have significant health benefits. Besides, RO membranes don’t accumulate pollutants but the membranes themselves gradually degrade with use. While the sediment and carbon filters will probably need replacement every 6 – 12 months, membranes should be changed every 2-3 years or as specified by the manufacturers.
Activated Carbon Filters
Activated carbon filters are particularly effective at removing pollutants which create unpleasant taste, odor, and color in water. These quick-change filters can eliminate or reduce the levels of chlorine by-products, pesticides, herbicides, and other organic and industrial chemicals.
They are small pieces of carbon, in granular or block formthat have been treated to be extremely porous. Just one gram of activated carbon can easily have a surface area of 500-3000m2. It’s the surface area that allows active carbon filters to be very effective in removing contaminants and other substances. Moreover, the surface area active carbon filters have different capabilities in terms of the size of contaminants they remove. These range from around 50 microns to 0.5 microns. The smaller the more effective.
