Frequently Asked Questions

• Why is Tap water Unsafe for drinking?
  Most of the time, tap water is not safe for drinking due to heavy industrial and environmental pollution. Toxic bacteria, chemicals and heavy metals routinely penetrate and pollute our natural water sources making people sick while exposing them to long term health consequences. Municipal water supplied for drinking is also not safe due to poor pipeline quality, parallel sewage pipelines, low maintenance, etc. Contaminants range from naturally-occurring minerals to man-made chemicals and by-products and microbiological organisms like bacteria, viruses and other pathogens, which cause serious diseases like Gastro-enteritis, diarrhea, paratyphoid, dysentery, etc.
• How can we make water safe for drinking?
  We can make water safe for drinking by using an effective water purifier, which removes all types of contaminants, be it physical, chemical or microbiological impurities. It should be clearly understood that traditional methods of water purification like boiling can remove only microbial impurities but are ineffective in getting rid of chemical impurities like pesticides and heavy metals, which may be toxic and carcinogenic and have long term impact on health.
  
  An efficient Water Purifier is based on a combination of effective technologies to remove all types of contaminants from water to render it safe for drinking.
  
  NASAKA Water Purifiers have different purification stages, which not only purify water but also add beneficial minerals to water.
• What is the difference between a Water Filter and a Water Purifier?
  A Water filter is the system through which undissolved particles/ solids can be filtered from water.
  
  Water purifier is a system through which dissolved solids along with undissolved solids/particles and Biological contaminations can be removed from water to make the water suitable for human consumption.
• What are the technologies used in NASAKA Water Purifiers?
  NASAKA Water Purifiers use a combination of several state-of-the-art technologies, which function stage by stage and the ultimate output water is completely safe for drinking. The following technologies are being used:
  
  

  • Reverse Osmosis
  • UV sterilization
  • Ultrafiltration
  • Nano silver technology
  • MINJET Technology

  
  
• What is Reverse Osmosis Technology?
  Reverse Osmosis is a separation process, which involves the passage of liquid from the lower concentration of dissolved substances to that of a higher concentration, when the two are separated by a semi permeable membrane. Thus, pure water is produced by screening out dissolved salts and other contaminants.
  
  Reverse Osmosis Membrane is made of Semi permeable membranes, made of cellulose acetate or aromatic polyamide, having pore size of 0.0001 microns in diameter. These can filter out most of the inorganic contaminants, microscopic parasites including viruses, which may cause serious health hazards.
• What is MINJET Technology?
  NASAKA Water Purifiers use unique MINJET technology to replenish essential and beneficial minerals in water and regulate pH of water. This is achieved by the use of a mineral cartridge consisting of mineral balls, antibacterial balls and pH balls.
• What is UV sterilization?
  UV sterilization utilizes UV light energy to deactivate any microbial contamination in water by altering their DNA structure and making them unable to reproduce and cause diseases. Water after passing through UV radiation gets free of disease causing microorganisms. we use this process for the Water Purifiers and provide UV Water Purifiers.
• What is Nano silver technology?
  Nano silver technology uses Silver particles of nano size (1m = 10⁹ nano meters), which are impregnated on activated carbon. Silver is a bacteriostatic agent, which inhibits growth of bacteria and activated carbon removes odour, organic impurities and improves taste of water. we use this technology and provide you the Best Water Purifier.
• What is Ultrafitration?
  Ultrafiltration is done by using Hollow fibre membranes having pore size 0.01 to 0.1μ. It is effective in the removal of colloids, proteins, bacteria, pyrogens (e.g. gram-negative bacterial endotoxins), and other organic molecules larger than 0.01µ.
• What is the function of different types of filter cartridges in NASAKA Water purifiers?
  Different types of filter cartridges are present in NASAKA Water purifiers. These help in prolonging the life of membrane and to improve water quality in terms of taste and mineral content.
  
  External Sediment Filter consists of spun PP and filters dirt, dust or other large sized suspended particles.
  
  Antiscalant balls. These are polyphosphate balls, which help to remove scaling and inorganic fouling. These reduce membrane cleaning requirements, thus enhancing domestic RO system performance. In addition to inhibiting carbonate and phosphate scale, antiscalants inhibit sulfate and fluoride scales, disperse colloids and metal oxides.
  
  Magnetic Softener utilizes strong magnetic fields that cause an electron excitation to occur in water. As water flows past these magnets, the molecules are aligned into a uniformed directional field. Water regains its solvency and will not allow minerals to form hard crystals of scale.
  
  In- line Sediment filter, which is made of spun PP of smaller pore size and filters smaller suspended particles.
  
  Pre-carbon filter, which consists of Granular Activated Carbon. These have very high surface area and remove contaminants through adsorption, a process in which dissolved contaminants adhere to the surface of the carbon particles. Activated carbon filter can remove organic impurities and chlorine. They are very effective in removing tastes and odours.
  
  Post carbon filter comprising of Nano silver impregnated activated carbon block. Silver is a bacteriostatic agent, which inhibits growth of bacteria in the carbon media. The post carbon filter is also known as polisher and enhances taste of water.
  
  Mineral cartridge, which consist of mineral balls to replenish the essential minerals in water and antibacterial balls which inhibit the bacterial growth.
• What is the storage capacity of NASAKA Water Purifiers?
  The storage capacity of NASAKA RO Water Purifiers varies from model to model. It ranges from 6 litres to 13 litres.
• What is the electrical consumption of EsselNasaka purifier?
  The consumption of electricity in water purifier is negligible ascompared to any other electric equipment in your house. NASAKA RO Water purifier system has a power consumption of 25 watts. It consumes 1 unit current only in 40 hours, in which time it can purify 4800 litres of drinking water.
  
  On an average, we use 20 litres of purified water per day in our house. According to this calculation, a household normally require 7300 liters of water per year. So the electric consumption will be approximately 1.52 units per year (Power consumption may vary slightly for different models).
• Does EsselNasaka remove essential minerals?
  Absolutely not. In fact NASAKA RIO water purifiers add beneficial and essential minerals through mineral cartridge, which constitutes different types of mineral balls, antibacterial balls and pH regulating balls.
• What if some parts stop functioning?
  If you face any problems with the NASAKA Water purifier or any of its parts, contact our 24x7 Customer Care number 1800 11 2323. Our Service Engineers will be prompt to help you.
• Where can I buy EsselNasaka purifier/ cartridge?
  You can purchase NASAKA Water Purifier/ cartridges through any of our authorized dealers. You should buy only genuine NASAKA cartridges/ components for best and trouble free performance.
