What to Check Before Buying an RO Water Purifier

Types of Water Purifiers for Your Home

  • RO Water Purifiers: Ideal for areas with high TDS levels, RO purifiers use reverse osmosis to remove impurities.
  • UV Water Purifiers: Suitable for water with low TDS levels, UV purifiers use ultraviolet light to disinfect water.
  • UF Water Purifiers: Ultrafiltration purifiers are effective in removing bacteria and viruses from water.
  • RO+UV Water Purifiers: Combining both RO and UV technologies, these purifiers offer comprehensive purification.

Which Water Purifier Should I Choose for My Home?

The choice of water purifier depends on factors like water quality, TDS levels, and specific purification needs. For areas with high TDS levels, an RO water purifier is recommended, while UV purifiers are suitable for low TDS water. Consider a combination purifier for comprehensive purification.

Water Purifier’s Warranty & Maintenance Cost

When selecting a water purifier, consider the warranty period offered by the manufacturer. A longer warranty indicates confidence in the product’s durability. Additionally, factor in maintenance costs, including filter replacements, servicing, and electricity consumption, to estimate the overall cost of ownership.

Which Aspect of a Water Purifier is Essential and Widely Recommended?

The most essential aspect of a water purifier is its purification technology. Ensure the purifier uses advanced filtration methods like RO, UV, or UF to effectively remove impurities, bacteria, viruses, and dissolved solids from water. Opt for a purifier with multiple stages of filtration for thorough purification.
