Types of Water Filters Based on Filtration Process

  1. Active Carbon or Charcoal Filters  

    best water filter system reviewsActivated carbon or activated charcoal is a form of carbon specially made to have small pores and increased surface area for adsorption of contaminants. The large surface area enables easy adsorption of pollutants like chlorine, pesticides, heavy metals, etc. The longer the time of contact between water and carbon, the better the removal of contaminants.

    The main drawback of this filter is that it often becomes home to various microorganisms over time. Ensuring that filter is sterilized over time is important to stop the breeding of microorganism.

    Fun Fact: Your body will absorb more chlorine, in a Ten-minute shower through your skin, than it will absorb from drinking 8 glasses of tap water.

  2. UV Sterilization

    best water filter system reviewsUV Sterilization works on the principle that radiation is absorbed by DNA and Proteins that successively causes the microorganism to denature and renders them inactive. Also it provides a comparatively low cost removal of microbial contamination in water. Care should be taken with water that fouls Quartz Sleeve, with deposits, this prevents ultraviolet light radiation from reaching water. Regular checking of Quartz sleeve and ultraviolet light lamp is usually recommended. Furthermore where high levels of Iron and manganese are present in water, longer exposure to ultraviolet light is recommended.

    UV filters/sterilizers for drinking water ought to have a minimum radiation dose of 30mJ/cm2 at the utmost point from lamp to make sure microorganism sterilization. Secondly lamp has quartz sleeve, if ultraviolet light lamp breaks or comes in direct contact with water, not solely would you be exposed to broken glass, but also Mercury that is usually present in ultraviolet light discharge lamps.

  3. Reverse Osmosis Filtration

If your water has dissolved salts in water, RO is the most preferred option. But there are chances that some contamination may pass through membranes. Thus, final water polishing stages will be required to ensure pure water. Reverse Osmosis filters are generally only for drinking tap water and do not have large filtration capability for household uses. Reverse Osmosis filters waste a lot of water. For each gallon of pure water 4 gallons of water are wasted.
