Water Purifier; Types, Features, Models, Brands, and Price Range
Water purifiers are devices that are designed to remove impurities and contaminants from water to make it safe for drinking or other uses. There are several different types of water purifiers available on the market, each of which uses different technologies to purify water.
One common type of water purifier is the activated carbon filter, which uses a bed of activated carbon to remove impurities and contaminants from the water. Activated carbon is a type of carbon that has been treated with oxygen to make it highly porous, which allows it to absorb impurities and contaminants. These filters are effective at removing chlorine, sediment, and other common contaminants from water, but they may not be as effective at removing more difficult contaminants like heavy metals or bacteria.
Another type of water purifier is the reverse osmosis filter, which uses a semi-permeable membrane to remove impurities from the water. This type of filter works by forcing the water through the membrane, which removes contaminants and impurities that are too large to pass through the pores. Reverse osmosis filters are effective at removing a wide range of impurities and contaminants, including bacteria, viruses, and heavy metals.
Other types of water purifiers include ultraviolet light purifiers, which use UV light to kill bacteria and viruses, and distillation purifiers, which use heat to vaporize water and then collect the purified water as it condenses.
In terms of brands, some popular options for water purifiers include Brita, PUR, and Berkey. Prices for water purifiers can vary widely depending on the type and size of the device, as well as the features and capabilities it offers. Some basic models may cost as little as $20, while more advanced models with additional features can cost hundreds of dollars.
