This article shares tips for selecting the best water purifier for your home.
1) Know the Quality of Your Water
Before buying a water purifier, determine the quality of water supplied to your house. To do so, you should get a quality check done by a professional. This information will also greatly ease your decision-making process.
2) TDS Content (Total Dissolved Solids)
Contaminants which are larger than 2 microns are known as 'Total Dissolved Solids' or TDS. For safe drinking water, the TDS should be < 500 ppm (parts per million). Based on research, it is known that tap water’s TDS content ranges from 1000-3000 ppm. Water with a high level of TDS (Total Dissolved Solids) can also change the taste of water and cause health hazards.
If the water at your home contains a high level of TDS (Total Dissolved Solids), we suggest you choose a water purifier with an RO + UV technology, whereas if the level of TDS (Total Dissolved Solids) is low, then an RO water purifier is the best option.
3) Type of Water Purification Technologies
In a marketplace brimming with buzzwords and catchy names, it can be hard to understand exactly what technology does. There are three primary types of purification systems that you should consider.
- RO or Reverse Osmosis
Purifiers that use reverse osmosis effectively eliminate dissolved salts, minerals, chloramines, nitrates, and heavy metals present in water by passing them through a permeable membrane.
- Ultra Violet (UV) and Ultra Filtration (UF)
UV (Ultra Violet) water purifiers are extremely effective in removing pathogens and microbes that can cause an array of water-borne diseases.
The water purification system used in UF (Ultra Filtration) uses a fibre membrane which eliminates suspended solids. However, UF cannot eliminate bacteria or pathogens.
- Activated Carbon Filter
The biggest advantage of using an activated carbon filter is that its strengths lie in removing trihalomethane (THM) compounds, chlorine, volatile organic chemicals (VOC), pesticides and other such similar impurities. It is ideally used in conjunction with additional purification systems.
Being aware of the above tips helps you make a confident purchase when it comes to water purifiers. Remember considerations such as capacity and durability – they will vary as per the needs of your family and daily habits.
- Get a water quality check done from a professional
- Determine the TDS content in the water at your home
- Choose a purification system based on the water-type and family size/needs
