Not all building products are created equally. Some products are eco-friendly than others. Sustainable building is big business so you should have a good number of choices for buying products that are on the 'greener' side. Work With Environmentally Conscious Builders Builders who are well versed on various things, such as grey water systems, green house plans, and creating more energy efficient homes are in demand. More people than ever want to know more than the price of building a home. They want to know that the builder will help them build an energy efficient home for the sake of the environment and their utility bills. They need these builders to construct their houses with the best and top quality given. When an individual is working with a builder, they also make sure that these are earth friendly and can meet with their expectations when they start building one. http://www.koyowater.com/html/en/products/purewaterproduceline/109.html The effects of 'hard water' on the pipe work and appliances of the home range from the obvious, visible, deposits of lime scale which are seen around the sinks, faucets and showerheads in these areas to the less obvious, but potentially far more costly, damage being done to the interiors of our expensive home appliances such as boilers, washing machines and dishwashers, leading to reduced efficiency and ultimately terminal damage. Other, filter based, whole house salt free systems are available such as those produced by Pelican and NuvoH20. These inhibit the ions of calcium and magnesium from forming as scale by safe chemical means and are an increasingly popular choice with those who are more environmentally conscious, with the added benefit that the treated water is safe to drink without further filtering as is the case with salt based systems. Most people opt to fit a series of filters designed to remove many types of contaminants for the ultimate provision of safe, clean, healthy water. http://www.koyowater.com/html/en/products/purewaterproduceline/159.html Business and industry have been instrumental in the disposal of waste materials into our fresh water supply sources. This inhabitation has directly contaminated the water supply and also upset the balance of water flow and creation established by nature. The US Clean Water Act, legislated in 1972, was intended to restore the physical, chemical and biological balance of water that had been disturbed by contamination. The Act specified that all natural water supplies would, at least, be safe for fishing and swimming by 1985. This specification led to the development of some form of water filtration and disinfection in every US city as well as advanced technological innovations in the filtering of water used in industry. Even so, the severity of past and continued damage has left more than 1/3 of all water supplies still polluted with contaminants. http://www.koyowater.com/html/en/products/purewaterproduceline/159.html In an effort to reduce the contaminants in drinking water and also to comply with national efforts to make drinking water safe, water-filtering systems have been developed to filter water within individual homes. Systems exist to filter incoming water for the entire house and also systems are designed to filter water, inline, at various points of water distribution within the house, such as at faucets and refrigerators or in water pitchers. The US based company, Omnipure Filter Company, credits its self with developing the first small, disposable, inline water filter in the world. The Omnipure CL Series of water filters, developed in 1970, were carbon-based, inline filtering systems designed for water coolers and ice machines. This benchmark water filtering system used granular activated carbon (GAC) to create cost effective methods of filtering water inline. Advances in the functionality, using the same basic design, have since led to the development of whole-house filters, faucet filters, countertop filters, pitcher filters, refrigerator filters and portable filters for camping.
