Weather Maps and Symbols. On any given day, there's plenty of activity on a weather map. Frontal boundaries and the Highs and Lows are the prominent features on an average weather map you might see on the TV news. Let's take a closer look at what they mean. Cold Front.

Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical absorption.Each particle/granule of carbon provides a large surface area/pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media.t is also used in cigarette filters. Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds.
How the Filter Works. As many of you probably already know, you place a filter inside a specially designed holder in your pitcher. This filter is ion exchange resin and activated carbon which work together to help reduce impurities. The carbon will reduce the amount of chlorine in your tap water which can affect the colour and smell.
