FAQ

  • Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates. The total water hardness is the sum of the concentrations of Ca2+ and Mg2+ and is usually measured in ppm or parts per million.
  • Total dissolved solids (TDS) is a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular, ionized or micro-granular suspended form. TDS, like hardness is also measured in parts per million. Hardness is usually a subset of TDS.

  • You may think that you do not see the problems of impure utility water, but answer these questions to understand if that is true:

    a. Do you see white marks on your taps and fixtures in your bathroom that are difficult to remove? – This is because hardness in water is caused by presence of calcium and magnesium which form salts that stick to surfaces they come in contact with. These are very difficult to remove and leave ugly looking marks on your expensive fixtures, basins, etc.

    b. Do you notice the force of water in your taps and showers going down? – This is because the salts stick to surfaces and clog them reducing the pressure in your taps and fixtures.

    c. Have you faced a difference in the lather while shampooing from when you visit a different place? – Hard water lathers much less thus reducing the efficiency of your shampoos, soaps, detergents. Soft water on the other hand gives you a great bathing experience.

    d. Do you see your hair getting dry and fizzy as soon as it dries? - Hard water leaves salts on your scalp making it dry and frizzy.

  • While both the products address the problem of hardness, they cater to different needs – Hardness levels in water, water consumption in a day, etc. In addition to this, the water softener uses the Ion Exchange Technology while the Scale prevention System uses the sequestering technology. Neither product can be said to be better than the other for all cases.
  • Ion Exchange Technology and Sequestering Technology are both technologies used to treat the hardness in water. While Ion Exchange technology uses Resin to capture and thus remove Calcium and Magnesium ions from water(replacing it with Sodium); Sequestering Technology uses Polyphosphate Media to encapsulate the Calcium and Magnesium ions making them chemically inert, but do not remove them from water. Thus while the hardness test (which only detects the concentration of calcium and magnesium), will show a reduction in hardness after the ion exchange process, it will show no difference in the hardness level after sequestering. However, the effects of hard water such as permanent white scaling on taps, faucets and fixtures, damaged hair and skin due to hardness is prevented in both cases.
  • The Scale Prevention System uses the sequestering technology that does not remove the Calcium and Magnesium ions from water but encapsulates them with food grade polyphosphate sequester which makes the Calcium and Magnesium ions chemically inert thus ensuring that that the effects of hardness such as scaling are eliminated. The Hardness/TDS test, only shows the presence of these ions which is not changed, however, the encapsulation ensures that the effects of hardness are removed, thus preventing scaling. Here’s a video to show the difference between untreated water and water treated by 3M Scale Prevention System: Video
  • Water Softeners only treat the calcium and magnesium content in the water reducing it to a tolerable limit. It does not treat the bacteria and other microbiological contamination in water that must be treated for the water to be potable – allowed for drinking.
  • Yes, Calcium and Magnesium are minerals required for the body. However, the body requires the same in limited quantity. Water containing 300ppm or less of Hardness is considered soft water.
  • These softeners are designed and manufactured specifically for residential purpose and are NOT softener plants meant for industrial applications.
  • In Villas, the softener can get installed right after the overhead tank or for a specific bathroom as per the requirement. In apartments, the softener can get installed for a single bathroom or if there is a single point of entry that is accessible for the specific flat. Please refer to the below image to get an idea of the installation point for Villas and Apartments.

  • Yes. 3M Home Water Solutions has a range of products for treating impure water to potable water/drinking water systems The 3M Drinking Water System. It also has a range of products that do not provide drinking water but eliminate/treat other impurities in water such as hardness, chlorine, sediments, etc. which cause a lot of hazards even when used for utility purposes.
  • Yes we have Water Softeners, specifically designed to fit into the flat. We can have the SFT100 installed inside your bathroom in your flat.
  • The recurring expenditure varies for each product, water quality and consumption. Please find your nearest dealer at Where to Buy or call us at 1800 425 425 000 to put you in touch with a nearest dealer.
  • Yes, we have a service team to handle the installation and any post sales service you might require. Please call 1800 425 425 000 for an installation request.
  • The installation cost is NOT built into the price and is not free. Please note that the cost of installation varies depending on the type and area of installation. For best rates and right installation, please have the installation done through a 3M Trained Technician. You can call us at 1800 425 425 000 to connect you with the same. The cost of any spares or additional requirements for installation will have to be borne by the customer.
  • The Fully Automatic Water Softener can handle a hardness level upto 1200ppm/ TDS value of 3000ppm. The Scale Prevention Systems can handle a Hardness level of 300ppm or TDS of 1000ppm. Please note that trained technicians will be able to serve a larger Hardness value by installing multiple units in combination.
  • The Fully Automatic Water Softener needs to be covered to protect it from the sun. The Scale Prevention Systems come with a transparent housing for easy cartridge viewing. However, this needs to be protected by the sun. In order to do the same, a Cover is provided with the product. If you do not receive a filter inside the product or from your distributor, call the toll free number 1800 425 425 000 for assistance.
  • Find an Installer to find your closest 3M Aqua-Pure certified plumber to install your 3M Aqua-Pure system, or Find a Distributor and visit one of our local distributors.
  • Your public water authority does the best it can to provide you with potable water. However, water passing through a series of pipes to reach your home may contain sediment. Therefore, a sediment filtration is advisable on the incoming water line. Our whole house sediment filtration and scale prevention systems help protect washers and seals from premature wear, prevent aerators and valves from plugging and keep your water heater from collecting excessive sediment.

    Additionally, if you do care for the taste of your home's tap water, a Whole house chlorine removal system along with a Sediment Filtration system reduces not only sediment but chlorine, taste and odour as well.
    Keep in mind that contaminant levels may vary depending on the season or the weather. Additionally, in the case of lead, the contaminant may not be accurately represented in water quality reports, as it may originate in a home piping system.

  • Our products vary in respect to ratings for contaminant reduction; among our line of offerings are products that reduce chlorine taste and odour, trihalomethane (TTHM), lead, sediment, cysts, arsenic, barium, cadmium, chromium (hex), chromium (tri), copper, fluoride, radium, selenium, turbidity, total dissolved solids (TDS), mercury, asbestos, chloramine, MTBE and volatile organic compounds (VOCs).
  • The size of the filter depends on the incoming pipeline size, your daily consumption and the water flow rate being delivered by the motor installed at your home.


    To suggest the best filter suitable for your specific needs, click on the Book a Home Visit link and our Authorised Distributors will visit your home to check the water quality and pipeline arrangement at your home and suggest the best suitable product.

  • There are several 3M filtration products that incorporate a scale inhibition agent. These cartridges, like the IAC420, utilise two important mechanisms to help inhibit scale and corrosion: one that helps prevent scale from forming and one that treats the surface of the piping to help prevent the negative effects of hard water scaling or corrosive water. In addition, 3M Scale and Corrosion cartridges incorporate a progressive porosity pre-filter for premium sediment reduction and long life.
  • Cartridge life may vary by product system and local water conditions. Product packaging will indicate approximate life of each system. Please use this as the guide to how often you need to change your filter. If you notice a drop in water pressure, it is recommended that you change your filter.
  • The Fully Automatic Water Softener can handle a hardness level up to 1200ppm/ TDS value of 2500ppm. The Scale Prevention Systems can handle a Hardness level of 300ppm or TDS of 600ppm.
