People today are aware that they need a water purifier at their home if they want clean and pure drinking water. The problem, however, is which water purifier to opt for with so many options available in the market. The market is, in fact, flooded with all types of filters using varied technologies each claiming to be the best.
The most modern and proven technology so far that suits almost all kinds of water supplies is RO water purifiers. All good companies like Kent are offering it and customers definitely have many queries regarding the same. Here is a list of the frequently asked questions along with the answers.
What Is RO or Reverse Osmosis?
RO is a technique that allows the flow of water molecules across a semi-permeable membrane and that too from a region of higher solute concentration towards that of lower solute. This is exactly opposite of osmosis process where the flow is from the area of lower concentration towards that of higher and hence the name. The pressure of the incoming water is used to push against the membrane and when that happens the water molecules pass through leaving behind bigger particles, which are nothing but the dissolved solids and some other impurities.
What Is the Best RO System Available in the Market?
Though all RO membranes produce highly purified water, the features might not be same in all. If you compare the RO water purifier price, you will find some models to be expensive than the others. This is because of the extra features that are available in them. There are units that have five-stage purification process and are appropriate for places that have the worst water quality. So, in these, there is a polypropylene pre-filter followed by carbon block cartridges for chlorine removal and then an RO membrane and again a carbon filter. Then, there are models that have efficient designing keeping conservation in mind. They produce more of purified water in less time and also the water wastage is less. Again, there are models that require very less maintenance. So, the definition of ‘best’ here changes depending upon the quality of water and budget.
Does Installing a Reverse Osmosis Unit Will Lead to a Lot of Water Wastage?
Well, it mostly depends upon the consumers based on what they consider as wastage. The waste water from the RO unit is not ideal for consuming, but you can utilise it for other purposes. You can wash your cars, clothes, or in your gardens. You can also use it to flush your toilets. The wastage is not exactly what it sounds like because once the storage tank of your purifier is full, the units shuts down and no water goes down the drain. In a normal family size, the entire wastage in the full day will be only around 2-3 buckets.
What Will Be the Annual Maintenance Costs?
The average annual maintenance cost actually is in the range of INR 1,500 – INR 2,000. It is only the pre-filters and post filters that need annual replacement for optimal functioning. Moreover, it depends on the quality of water coming in your house and the frequency of use. Depending upon these factors, the RO membrane can last anywhere between two to five years.
How Long Will the Unit Last?
It is an investment for life if you get it serviced regularly. Only if the technology changes completely and you wish to switch to a newer one, you will need to change it or else the unit will keep working tirelessly and efficiently for a long-long time.
Water purifiers are a basic necessity in today’s world wherein almost all sources or water are contaminated in one way or the other. It’s just that you need to do your research to find out which purifier would be the best choice for the water you get at your home.
