3. Kent Grand Star RO

Kent Grand Star RO Purifier

I have been looking for a replacement for my old water purifier for a long time. I was very upset by the manufacturers for their promises of after sales service.

When my old water purifier had a filter problem, it took almost four days for a technician to fix the problem.

I have a large family, and giving them anything other than purified drinking water would mean that they would all get sick one by one.

Kent Grand Star RO Review

Decided to look for the best water purifier for the home. I found out that Kent came up with an intelligent reverse osmosis system, so I decided to check it out.

This is truly the best water purifier from Kent. The device has a smart touch screen, a large illuminated water tank and a number of other features.

Kent has upgraded its patented, tried and tested RO+UV dual cleaning technology to superb levels. The Kent Grand Star is said to be the world’s first smart water purifier.

The built-in digital touch screen provides real-time monitoring of water purity and device performance.

The computer chip also provides automatic on and off, resulting in longer filter life.

The touch screen dashboard is quite easy to use and has 4 tabs; Status, Service, Help and Settings.

The status tab is more like a dashboard that shows the reverse osmosis flow rate, time, water quality, and balanced filter life.

The “Service” tab is primarily intended for technicians to update information about any work done on the device.

The Help tab provides product features and a troubleshooting guide. The Settings tab is used to set the time, date and screen brightness.

I was sure my search was over. Another reason that made me even more satisfied is the customer service.

Judging by the reviews of other buyers and the assurances of the manufacturers themselves, I decided to buy the Kent Grand Star.

When I use this reverse osmosis purifier for my family, I am definitely relieved. This assures me that I will always have the best water treatment system on the market.

Another feature is that, unlike UV purifiers and only reverse osmosis purifiers, Kent Mineral ROTM water purifiers remove impurities dissolved in water, such as chemicals, pesticides, rust, etc., while retaining the main natural minerals that are essential in drinking water.

Trunk capacity is 9 liters compared to 8 in previous models. The shatterproof feature of ABS plastic ensures higher strength and longer cleaner life.

Food classification ensures that no harmful chemicals enter the purified water.

Be sure to read the manual carefully and listen to the advice of technical experts.

It makes no sense to buy the most expensive water purifier and not use it for its intended purpose.

In general, I am very pleased with the purchase. It’s really more expensive than the rest, but why would anyone complain about paying a little more when you’re convinced it’s for your own well-being.

Aquaguard Regal RO Review

Aquaguard Regal RO ensures pure drinking water, especially water with high TDS levels. The various filters and cartridges clean and purify the water but enhances the taste too.

But this RO water purifier does not have UF technology which plays a vital role in the purification. The Ultrafiltration (UF) technology removes the dead bacteria present in the water.

Also, it comes with a storage capacity of 8 litres which is sufficient for a small or medium sized family. Its price is comparatively at par with the other products that its competitors offer.

But the maintenance for this purifier is expensive and you may have to spend a lot of your money to change the filters and cartridges from time to time.

Filters and cartridges are essential parts of any purifier and have to be changed on time for proper operation of the purifier.
