Hundreds of pollutants can't be controlled and no every pollutant can be tested out.

Your drinking water may contain the pollutants; germs, asbestos, lead, radio active minerals, particles and industrial scraps, animal waste, virus, microbes etc.  

There are now thousands of chemical compounds containing toxin and new chemical compounds will be invented and used every year.  these chemical compounds will pollute the ground and under ground water.  And some of these chemical compounds intruding into the drinking water have been approved as the cause of variety of diseases.

• Removes 99% of all the Total Dissolved Solids, such as, heavy- metals, bacteria and viruses from the Tap Water.
• No need to boil water - Energy saving.
• The water is rich in Oxygen which is good for our blood. 
• Water is sweet and tasty.
• Pure water costs less than 50 Paise per Litre, when made in house. 

• Quality isn't certain 
• Sanitation is questionable.
• Price isn't cheap.  
• Costs about Rs. 2 per Litre!
• Inconvenient depending on outside source.
• Fear of pesticide in water.

• Energy wasted in heating.
• Can only kill germs.
• Quickens the reaction of organic substances and chlorine in the water to produce tri-alkalic ethane.
• While boiling water, steam boils and the polluted density in the water increases.
• Salt deposit of chemicals in the vessel.

• High power cost and energy wasting for long-term use.
• No oxygen in the water and bad taste.
• Maintenance is often required, It's more cumbersome.
• Organic volatile matters such as tri-alkalic methane can't be eliminated. 

• High operating cost.
• Professional maintenance needed.
• Only heavy metals can be eliminated, but there is a lot of chemical left, that can result in heart/blood vessels diseases or hypertension.  Most of organic compounds and germs can't also be eliminated.
• Water does not taste good.

• Quality isn't certain, uniform and its efficiency has big differences.
• Germs, heavy metals, asbestos, nitrate and salt can't be eliminated.
• Becomes a growing place for germs.
• Suitable for odour removal and taste.
• Effective as a pre treatment or post treatment. 

• Only germs can be killed.  Its effect is no better than boiling water.
• High cost.  Lamp tube must be replaced/cleaned in every 3 or 6 months for effective sterilisation.
• Pollutants can't be eliminated except germs killing.
• Does not remove chemicals and heavy metals.
• Hard water makes the UV lamp ineffective by scaling.
• Taste of water doesn't change. 

• The running water is pure, clean, healthy and can be safely drunk!
• The equipment of the running water can eliminate all pollutants!
• The government understands what particles exists in the running water and thoroughly inspects them to assure safety!
