Dos and Don’ts of Using a Water Purifier

These days, using a water purifier is very important to make sure you have safe drinking water in your homes. But just buying one is not enough. There are proper ways to use and maintain it so that the machine works well and lasts longer. Le us cover the water purification dos and don’ts, common mistakes people make, and tips to increase the lifespan of your purifier.

Do’s of Using a Water Purifier

 

  1. Do clean or replace the water filter cartridge of your purifier regularly. The manufacturer typically specifies the frequency at which you should clean it in the user manual. Cleaning the filter ensures the purification system functions properly and prevents contaminated water from entering. 

     

  1. Do use a purifier suited to the source of water you have in your house or apartment, whether it is a tap, borewell, or tanker. Check if your purifier requires reverse osmosis for hard water. 

     

  1. Do flush the system after installing the purifier or even after filter changes. Flushing will remove any debris and loose carbon particles (if the machine has activated carbon). 

     

  1. Do keep the purifier machine in a clean, cool, and ventilated place without a lot of moisture or sunlight. Sunlight and humidity can damage the filter parts. 

     

  1. Do follow the instructions of use given in the user manual or instruction card. Use the correct voltage and the right input point. 

     

  1. Do keep monitoring the taste, smell, and flow of water. If there are any changes, you may need to perform some maintenance or replace the filter. 

 

Don’ts of Using a Water Purifier

 

  1. Do not ignore maintenance. If you delay changing the filter for too long, bacteria and sediments can accumulate inside your machine. This can reduce the efficiency of water purification and is also very unhygienic. 

     

  1. Don’t use the purifier without water, or leave it unused for too long without cleaning it. 

     

  1. Don’t use detergents, soaps, or very harsh cleaning liquids inside the purifier tank of the pipework of the machine. If it is applicable, it will be mentioned in the user manual. 

     

  1. Don’t ignore any indicators or warning lights (filter change, UV failure, etc.). These are safety signals for water purification. 

     

  1. Don’t skip pre-filtration for filthy water. If your water source is highly contaminated, you should avoid feeding it directly into the purifier. The filters become overworked, and their lifespan is reduced. 

 

Common Mistakes People Make with Water Purifiers 

 

  • Using the wrong type of water purifier: not getting reverse osmosis when needed, using RO for already spotless water (it can be very wasteful). 

     

  • Forgot to replace activated carbon filters. Even if the water appears clear, the filters must be replaced regularly. 

     

  • Overlooking storage tank cleaning. Even if the purifier works, if the tank is dirty, the water can be unsafe. 

     

  • Not checking certified or genuine parts. Using an inferior or counterfeit water filter cartridge can render your water unsafe or even damage your machine. 

 

Tips to Increase the Lifespan of Your Water Purifier

 

  1. Use pre-filters like sediment or mesh filters to filter any bigger particles before they reach the main cartridges or RO.

     

  1. Follow a proper filter change routine: usually pre-filters every 6-12 months, carbon/post filters yearly, RO membrane about every 2 to 3 years, depending on water quality and usage.

     

  1. Clean the tank regularly and sanitise the water storage section or tank well. 

     

  1. Keep your purifier away from direct sunlight, heat, and moisture.

Choosing the correct type of water purifier (RO/UV/UF, etc.), keeping up with filter changes, cleaning, and using the purifier properly ensures that your water for drinking is truly safe, the purifier lasts longer, and you avoid unnecessary repair and replacement costs.
