Frequently Asked Questions About KENT RO Water Purifier

1. Does the Best KENT RO Water Purifier remove Arsenic and Lead?

Yes. One of the main reasons KENT is considered the best in BD is its advanced RO (Reverse Osmosis) membrane. It is specifically designed to remove dissolved impurities like Arsenic, Fluoride, Lead, and other heavy metals commonly found in Bangladesh’s groundwater.

2. What is the difference between RO, UV, and UF?

UF (Ultra Filtration): Removes physical particles and cysts. The Best KENT RO Water Purifier models use all three technologies plus TDS Control to ensure 100% pure water.

3. Does KENT water taste “flat” or “bitter” like other RO filters?

No. Standard RO filters often remove all minerals, making water taste flat. However, KENT’s patented Mineral RO™ technology uses a TDS Controller that allows you to retain essential natural minerals, ensuring the water is both healthy and tasty.

4. How often do I need to change the filters?

In Bangladesh, it is generally recommended to change the sediment and carbon filters every 6 to 12 months, depending on your local water quality. The RO membrane typically lasts 2 to 3 years. Most high-end KENT models have a “Filter Change Alarm” to notify you automatically.

5. Is a KENT water purifier suitable for Dhaka’s supply water (WASA)?

absolutely. Even if the WASA water looks clean, it often contains pipe rust and bacteria. For WASA water with low TDS, a UV or UF filter might work, but for total safety, a KENT RO system is the best choice to handle unexpected contamination.

6. What is the “4 Years Free Service” offer in BD?

Most authorized KENT dealers in Bangladesh provide a 1-year warranty on the product plus 3 years of extended free service. This means you don’t pay for the technician’s visit for 4 years; you only pay for the spare parts if they need replacing.
