There are a number of different features that determine both the quality and performance of a water filter. These features include the mineral make-up of the media, the amount of surface area in the media, the size of microns removed by the filter (also known as micron rating), and the regulated flow rate of the filter.
Multi-Pure’s Carbon Block Filter Media
Mineral Media: Water filters can be made from ceramic, charcoal, or carbon media, but carbon is quickly becoming the most popular choice, as it is inexpensive to produce and highly effective. The two most common forms of carbon media are granulated carbon and activated carbon block. While both filters are effective, carbon block filters offer a larger amount of surface area and generally remove more contaminants.
Media Surface Area: The media surface area of a filter refers to the amount of activated carbon that is exposed to water and contaminants. One pound of carbon media offers approximately 125 acres of activated surface area. The greatest number of contaminants can be removed when the activated surface area is at its highest.
Micron rating: The micron rating of a filter determines the size of particles that can be removed mechanically by the filter. Micron ratings range from 50 to 0.5, with the smallest micron ratings being the most effective. A water filter media that measures at 0.5 microns is considered sub-micron and will be the most effective at reducing the majority of contaminants.
Flow rate: The performance of a water filter is also determined by the amount of time water is exposed to the filter media. This amount of time is generally calculated by the flow rate of the filter. Different sizes of filters can process water at different rates of speed. While a relatively fast flow of water is ideal for adequate pressure, contaminants need a certain amount of time in the filter for proper exposure to the media. Larger filters can handle more water and will have higher flow rates, while smaller filters must maintain slower flow rates for adequate exposure time.
Each of the above features, as well as the particular technology the filter uses, determines the number and degree of contaminants a filter can remove. Based upon their specifications, water filters are ideal for removing chlorine and other chemical contaminants from drinking water while retaining trace minerals for better taste and pH balance. They have proven to be one of the best water treatment solutions for municipally treated water.
All Multi-Pure drinking water filters come with a 0.5 micron rating and are proven to reduce the most contaminants of health concern.
