Water purifiers are a must-have appliance these days for most of the houses as water is contaminated to the worst possible levels in many areas. The market is flooded with multiple water purifiers using different technologies and at varied prices. All claim to be the best among the lot having their own USPs. In such a scenario, it is but natural that the consumer is confused and has a lot of queries.
Here are 6 of the most frequently asked questions about UV water purifier answered.
- What Is a UV Water Purifier?
It uses UV light to purify water that has a high percentage of microbes. UV stands for Ultraviolet and it is a light that we cannot see and exists at the violet end of the light spectrum. Though we cannot see it, we are exposed to it from all light sources. Even sun rays contain UV rays. It is undoubtedly the best water purifier for home.
- How Does It Purify Water?
UV rays penetrate through the cells of the microbes present in water and destroy their ability to reproduce. Thus, the organisms die without multiplying and water gets purified. This process is effective in rendering 99% of harmful microorganisms inactive and hence is a very effective method of purifying the water from harmful microorganisms that can cause a lot of health diseases like jaundice, dysentery and gastro problems.
- Can’t We Use Chlorine Tablets for That?
Chlorine is known to change both the taste and odour of water. There is also a possibility of production of harmful by-products called THMs (Trihalomethanes) in the chlorination process. These THMs may lead to cancer.
- Will This UV System Be Expensive to Run?
This system doesn’t use a lot of energy. The amount of electricity that it consumes is similar to running a 60 watt light bulb. Hence, it is very cost effective and anyone can afford it easily. It gives you complete peace of mind in areas where microbiological contamination of water is a big worry by purifying it almost completely.
- How Often Does the UV Light Bulb (Lamp) Need Replacement?
The UV lamp, which is the main component of these purifiers, does not require replacement very often. It is either done annually and for some models, it can even last up to two years. It is important that you get it replaced as per the instructions given in the handbook as the manufacturer would have instructed that for a purpose. The ability of this lamp to emit UV light decreases with time and even if the lamp glows after the required time it might not be working efficiently to purify water effectively. The manufacturer sets the duration after rigorous testing of components and thus you should follow the instructions given in manual properly for properly disinfecting the harmful microorganisms present in water.
- What Is the Requirement of Sediment Pre-Filtration in UV Sterilizers?
The sediments and other contaminants that are present in the water are notorious for creating a shadow. This prevents the UV rays from reaching the desired areas and rendering the harmful microorganisms incapable to reproduce. Thus, sediment pre-filtration is required to maintain the effectiveness of the cleansing process.
Hope these queries and answers would have clarified most of your doubts about UV water purifiers.
