How long do reverse osmosis filters last?
What is RO?
RO is the shortened form of reverse osmosis. It is a purification method used in various water filters today. The water is passed through a semipermeable membrane also known as RO membrane in filters with pressure so that the contaminants are filtered out easily. Reverse osmosis water purification methods can remove 99% of water contaminants, including heavy metals such as lead, zinc, copper, mercury hazardous chemical compounds, viruses and bacteria.
How to RO (Reverse osmosis) filters work
RO filters have filters which need to be replaced after a certain time period. There are different stages of filtration in the RO purification method. This is a long process with many filters in between so it takes some time to process. First of all RO filters have pre filter membranes which removes bigger impurities such as stones, sand and make sure the RO membrane will only get safe water.
Now, when the water reaches the RO membrane, it is free of bigger contaminants. The water molecules are forced through this reverse osmotic semipermeable membrane with high pressure so the heavy metals such as lead, mercury, copper, zinc chromium and harmful chemical compounds such as fluoride, chlorine are removed.
After getting passed through the RO membrane now it’s time for the post filter, also called as carbon filter which makes sure there are no contaminants left in the water so that you can have safe and healthy drinking water. Many RO water filters also have a remineralization system which makes sure the good minerals such as calcium and magnesium are added in the water.
For what time do RO filters work efficiently
The lifespan of an RO filter totally depends on your usage and the time specified by its manufacturer. Reverse osmosis water purifiers can last until they are in excellent condition and with no breakage. Moreover, many manufacturers also have replacement and recycling programs so do make sure your purifier has the service. The filters inside the purifiers need to be changed frequently.
Depending on your manufacturer and your usage, the filter life may vary. Check out your water purifier user manual to know the exact time for which you can use the filter. Some filters can be used for a year, 6 months and some for only a month. Moreover, the water capacity such as 1000 gallons will be specified. Some RO water filters also come with an electronic indicator which tells the exact time to change the water filters.
Additionally, if your filter doesn’t have an indicator, change the filter as per the time specified by the manufacturer. If you don’t change the filters on time, the water quality will be degraded. Moreover, it will not be purified and taste bad. Therefore, replace those filters frequently.
