FAQ's

The A. O. Smith X4+ RO water purifier is advanced 5 stages RO from AO Smith. It is a 100% RO water purifier for maximum purity.

In some ordinary RO+UV water purifiers, some amount of water is made to bypass the RO membrane. Due to this, harmful substances like TDS, heavy metals, chemicals, and pesticides also pass through. Whereas in A. O. Smith RO water purifier, 100% of the water is passed through the RO membrane which ensures maximum purification of water.

A. O. Smith X4 RO has 5 stages of purification. These are:

1. Pre-filtration
2. Sediment filtration
3. Pre-carbon
4. RO membrane
5. Silver activated post-carbon.

There are other alerts and indications built in the system to indicate or alert the user if there is any problem in the system.

When the cartridge reaches 90% of its life, the indication light for the respective change glows in the product. Upon reaching 100% of its life, the purifier stops the process for pure water.

First indication is at 90%, at this point the respective change indicator starts glowing. On 100% life consumption there is a constant light in the respective indicator with buzzer beep. The buzzer will beep every time the unit is switched on.  

The life of the RO membrane is 12000 liters of pure water. It may last for up to 2 years basis 15 liters per day consumption under the input water norms. (Input water norms TDS less than 2000, hardness less than 400).

Advanced unique SSM stands for side stream membrane technology. Unlike the traditional membrane, this membrane has water inflow from 2 sides which results in better recovery of pure water and rejection of salts and other toxins and impurities. It results in better membrane life.
