subject: Countertop Reverse Osmosis Water Filter: For Purifying Water [print this page] Countertop reverse osmosis water filters are a cost effective selection for purifying water. These systems run from fifty to three hundred dollars. In comparison with the cost of buying a pack of bottled water every week or more often, which ends up costing at a minimum twenty five dollars per month, a fifty dollar system pays for itself within, at most, a two month's time period. In addition, there is the convenience of having pure water right at the faucet, rather than having to go to the store in order to be sure of the water being used.
Reverse Osmosis Water Filtration
Countertop reverse osmosis water filters utilize a membrane which has tiny holes in this. These holes only allow water molecules to pass through to the other side, therefore allow pure water. Chemical substances, metals and minerals get caught in the membrane; therefore the pollutants are weeded out.
The great feature with countertop reverse osmosis water filters is that they could be hooked up by an individual without the assistance of a plumber. These systems hook up to the faucet rather than needing to be hooked to the water pipe under the sink, so a person with common household tools can easily hook up the system and get started. Moreover, the tank for the countertop reverse osmosis water filter holds much more water than the pitcher or other portable reverse osmosis water filters; therefore it maintains a consistent supply of pure water for an entire household to use.
Other Forms of Filtration
There are two types of water filtration systems which have been on the market the longest and are most common. One of them is the absorption water filtration system in which charcoal and carbon is used to absorb substances from the water. It is great for removing things such as chlorine which make the water taste bad, and is sometimes used in conjunction with reverse osmosis water filtration systems to remove the chlorine from the water before it enters a unit like a countertop reverse osmosis water filter. The membranes in reverse osmosis filters are sensitive to chlorine and will be damaged by this, decreasing their life.
The other kind of countertop reverse osmosis water filter which is common is a micro filtration unit that filters out sand, bacteria and other particulate matter from the water, like Giardia. These units used to be very popular as camping filters; sometimes paired with absorption systems to eliminate as numerous contaminates as possible from the water on a campsite.
