Reverse Osmosis Water Filters

Reverse osmosis is one of the most popular methods of water filtration in the home. By forcing water through a membrane with very tiny holes, reverse osmosis water filters removes minerals, impurities and other solids that can’t pass through the membrane.

To find out how reverse osmosis got its name, you must first look at osmosis, which is a process through which water with low levels of content (minerals, solids, etc.) passes across a membrane, without the use of additional energy, into water with higher levels of content. Eventually the water on both sides of the membrane has similar levels of content. In contrast, the reverse osmosis process forces water with high content through a membrane so the water on the other side has lower content. Following osmosis, the water on either side of the membrane has similar content; following reverse osmosis, the water on opposite sides of the membrane has different levels of content.

Reverse osmosis is popular for water filtration because it can improve water that is already drinkable. While municipal water is filtered to a high level and meets certain standards for health and purity, there are still solids present in municipal water that can affect taste, odour and colour. When municipal water is put though a reverse osmosis filter, those solids are removed resulting in cleaner, better tasting water.

It is important to note that reverse osmosis water filters are not a good choice if the water source is not safe for drinking. While reverse osmosis filters remove many solids, some microorganisms can be small enough to pass through the membrane, so reverse osmosis does not disinfect water. Another potential problem that could lead to contaminated water being passed through a reverse osmosis filter is leaks or tears in the membrane, which would allow water to pass through the filter without being treated.

Water supplied by your municipality is perfect for a reverse osmosis water filter. However, if your water comes from a well or some other private supply, it should be tested before using a reverse osmosis filter or it should be put through a disinfecting filter first. This means that the water will be safe to drink even if there is a tear or other leak in the reverse osmosis membrane.

Water pressure can also affect the ability of reverse osmosis filters to remove solids from water. If pressure is too low, it will not be enough to filter out as many solids as possible. Generally speaking, reverse osmosis water filters need water pressure of at least 40 psi to be effective.

While reverse osmosis is a relatively low cost water filter option, they do not always use water efficiently. Depending on the amount of contaminants contained in the incoming water, reverse osmosis systems might use four or five litres of contaminated water to produce one litre of filtered water. The result is that flow rates from reverse osmosis are relatively low compared to some other water filtration methods. The implication for anyone using a reverse osmosis water filter is that if they require large amounts of water on an ongoing basis, they will need some sort of storage system to accumulate sufficient amounts of filtered water to meet their peak demands.

Reverse osmosis is so effective at removing solids from water, it is perhaps the best water filtration method for removing unwanted minerals from your water. It is effective is removing total dissolved solids, turbidity, asbestos, lead, other heavy metals, radium and some dissolved organics. Its ability to remove solids is why reverse osmosis is used so extensively in water desalination processes.

When homeowners add an active carbon water filter to their reverse osmosis system, the combination results in one of the most effective water filtration methods for removing the widest range of water impurities and contamination.

Many reverse osmosis users are unaware of how effective it is at removing one of the most dangerous water contaminants for some people. Reverse osmosis water filters are very effective at removing plutonium and strontium from water to reduce levels of radiation in drinking water around nuclear power plants.
