Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical adsorption. 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. One pound (450 g) of activated carbon contains a surface area of approximately 100 acres (40 Hectares). 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. Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 micrometres. Carbon filtering
You may be surprised to know that even indoor air can be polluted, sometimes more so than outdoor air. And because many people who have COPD or other chronic health conditions spend a great deal of time indoors, improving indoor air quality is especially important. To help you improve the quality of your indoor air, here are 11 steps designed for those with COPD or other chronic illnesses. Indoor Air Quality - Improving Indoor Air Quality

How to Remove Fluoride from Drinking Water Most people are aware that there is a controversy surrounding public fluoridation of drinking water. Here is a list of ways to obtain drinking water without fluoride. In addition, I've listed water purification methods which do not remove fluoride from water. Ways to Remove Fluoride from Water Reverse Osmosis FiltrationThis is used to purify several types of bottled water (not all), so some bottled waters are unfluoridated. Reverse osmosis systems are generally unaffordable for personal use.Activated Alumina Defluoridation FilterThese filters are used in locales where fluorosis is prevalent.
