How does it purify your water?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To put it simply, RO stands for<\/span><a href=\"https:\/\/drinkprime.in\/water-purifier-on-rent\"><span style=\"font-weight: 400;\"> Reverse Osmosis<\/span><\/a><span style=\"font-weight: 400;\">. RO uses a high pressure membrane to remove dissolved salts, nitrates and heavy metals such as arsenic. RO can bring down your water\u2019s TDS (Total Dissolved Solids) significantly because it removes the dissolved solids present in your water. TDS is measured in parts per million (ppm).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">RO is not capable of removing biological contaminants like bacteria and viruses, which a UV lamp can do. RO also usually removes the \u2018good\u2019 minerals present in your water during the purification because it cannot distinguish a good solid from a bad one. Naturally occurring water is known to contain minerals like calcium and magnesium.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some purifiers let part of your tap water skip RO purification to adjust TDS. This may leave some impurities behind. DrinkPrime\u2019s RO purifiers don\u2019t do this. DrinkPrime\u2019s purifiers make sure every drop of your water goes through 100% RO purification. Because RO removes the essential minerals, there is a separate mineraliser cartridge that adds back calcium and magnesium before your drinking water reaches your glass.\u00a0\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"DrinkPrimes_100_RO\"><\/span><span style=\"font-weight: 400;\">DrinkPrime\u2019s 100% RO<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">DrinkPrime offers a range of purifiers with 100% RO on rent. All of DrinkPrime\u2019s purifiers (except for UV, which has the UV lamp and not RO) have the high-reject RO membrane, which purifies your water to the last drop.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These purifiers are available on a subscription basis where you can pay a monthly rental and use the product.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Apart from the RO membrane, these purifiers have the dual filter (sediment &amp; pre-carbon), a UV lamp, the combined cartridge (post-carbon &amp; mineral), a copper cartridge (in the case of a copper purifier) and an alkaline filter (in the case of an alkaline purifier).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">DrinkPrime\u2019s purifiers are IoT (Internet of Things) powered, which means, they use the smart technology to track your purifier\u2019s health, the filter health and your water consumption. As a customer, you can also recharge through the DrinkPrime app.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One of the biggest benefits of choosing DrinkPrime is hassle-free maintenance the company offers.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_does_RO_maintenance_matter\"><\/span><span style=\"font-weight: 400;\">Why does RO maintenance matter?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">RO maintenance matters. This cannot be stressed enough. If you\u2019re living in one of the metro cities in India, there is a high chance your water has high TDS. To give you context, high TDS is generally in the range of 600-1000 ppm. Excessive environmental pollution can make impurities leach into your drinking water source. The water that comes out of your tap will have a high TDS which requires RO.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Because the RO membrane blocks all the solid impurities in the water, impurities can build up in your filters, membrane or cartridges. In the case of DrinkPrime, the purifiers are designed to stop dispensing water so that you don\u2019t consume impure or unfiltered water. If your filters or your RO membrane is blocked, then it is a sign that your purifier is working well.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If annual maintenance is skipped, your filters or cartridges can clog, which reduces water flow.\u00a0 This would also affect your purification quality, and the impurities can end up in your drinking water.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Parts_that_need_replacement_Filters_membrane_and_others\"><\/span><b>Parts that need replacement: Filters, membrane and others\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A water purifier has multiple stages, with multiple filters and cartridges. For your water purifier to dispense clean drinking water, all of the filters, membranes and cartridges need to be working perfectly. Every purification stage has a lifespan. Listed below are the purification and replacement stages.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">a) Dual filter (sediment &amp; pre-carbon)<\/span><\/p>\n<p><span style=\"font-weight: 400;\">What it does<\/span><b>:<\/b><span style=\"font-weight: 400;\"> Removes traps sand, silt, rust and visible particles before they reach the later stages.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Replace when<\/span><b>:<\/b><span style=\"font-weight: 400;\"> Water flow drops, or the filter looks visibly dirty or discoloured.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">b) RO membrane\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">What it does: It removes dissolved salts, heavy metals and many contaminants.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Replace when: TDS in purified water rises, output slows, or wastage increases.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">c) UV Lamp<\/span><\/p>\n<p><span style=\"font-weight: 400;\">What it does: Inactivates bacteria and viruses.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Replace when: The lamp reaches the end of its rated life. UV output fades gradually.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">d) Combined Cartridge (Post-Carbon &amp; Mineral)<\/span><\/p>\n<p><span style=\"font-weight: 400;\">What it does: Post-carbon filter provides<\/span><span style=\"font-weight: 400;\"> a final polish by removing residual odours<\/span><span style=\"font-weight: 400;\">, and improving taste and clarity. Mineral cartridge adds back essential minerals such as calcium &amp; magnesium.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Replace when: When the flow rate drops.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Other components:\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Antiscalant (in DrinkPrime\u2019s Chennai variant): Reduces scale buildup on the membrane. Replace when visible scale buildup appears.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Iron remover (In DrinkPrime\u2019s Kolkata variant): It removes the excess iron.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Mineral or copper\/alkaline cartridge (in models that have one): Adds minerals back after RO.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">They can be checked for replacement during a general inspection.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_does_DrinkPrime_handle_maintenance\"><\/span><span style=\"font-weight: 400;\">How does DrinkPrime handle maintenance?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Usually, a general inspection for any purifier is carried out annually. A general inspection is advised when there is an evident drop in your output water flow.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you own a water purifier, one of the major drawbacks is that you need to pay extra for the annual maintenance that is carried out. You also need to track your purifier\u2019s health by yourself and call a technician when there is an issue. With DrinkPrime, however, your purifier is tracked remotely and a technician visit is arranged when needed.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you feel there is something wrong with your purifier, you can check your app to track your filter health. You can also raise a service request on the app and a technician will visit you at your convenience.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You can request a general service if your water consumption crosses 6,000 litres or you have completed one year, whichever comes first. You can track your water usage on the DrinkPrime app.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Even in the harshest water conditions, your water purifier is built to handle 6,000 litres of water. With lower TDS water, it tends to last longer than that. A regular inspection, regardless, helps keep your purifier in check.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At DrinkPrime, a general service typically covers backwashing of sediment and carbon filters, cleaning the storage tank, wiping internal and external surfaces, checking flow rate and checking output water quality.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Even though general service doesn\u2019t automatically include filter replacements, filters are changed if a filter or a cartridge has reached the end of its useful life.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><span style=\"font-weight: 400;\">Conclusion<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Your <\/span><a href=\"https:\/\/drinkprime.in\/\"><span style=\"font-weight: 400;\">RO water purifier<\/span><\/a><span style=\"font-weight: 400;\"> works on its own. Because it doesn\u2019t draw your attention on a daily basis, it is easy to forget it needs servicing at least once a year. If you forget to do that, you and your family may not get the purified water you deserve.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Replacing filters and cartridges and staying on top of your purifier health are small habits that will make a big difference to your daily life. If tracking your purifier\u2019s health seems like a big to-do list, DrinkPrime handles it for you. At DrinkPrime, your purifier\u2019s maintenance is taken care of, for free, included in a monthly subscription that starts at \u20b9349\/month.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span><span style=\"font-weight: 400;\">Frequently Asked Questions<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><b>1. How often should I service my RO purifier?\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400;\">At least once a year.

What happens if I don\u2019t service my RO purifier?\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Filters and cartridges clog, flow drops and purification quality can suffer. DrinkPrime purifiers stop dispensing water when blocked.<\/span><\/p>\n<p><b>4. How long does an RO purifier last before service?\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400;\">It depends on your water\u2019s TDS. DrinkPrime purifiers are built to handle 6,000 litres even in harsh water conditions, and last longer with lower-TDS water.<\/span><\/p>\n<p><b>5. Can I clean my RO purifier at home?\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Wiping the outside is fine, but filters, the membrane and the tank are best left to a technician.<\/span><\/p>\n<p><b>6. Does DrinkPrime\u2019s general service include filter replacement?\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Not automatically, but filters are changed if they\u2019ve reached the end of their life.

What is the difference between RO and UV purification?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">RO removes dissolved solids and heavy metals, while UV inactivates bacteria and viruses. DrinkPrime combines both.<\/span><\/p>\n<p><b>8. Does RO remove essential minerals?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Usually yes. DrinkPrime\u2019s mineral cartridge adds calcium and magnesium back.<\/span><\/p>\n<p><b>9. How do I raise a service request with DrinkPrime?\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Through the app; a technician visits at your convenience.<\/span><\/p>\n<p><b>10.
