Design and Build Quality

The biggest attraction of the AO Smith Z2+ Luxe RO under sink water purifier is its hidden installation style. Unlike regular wall-mounted purifiers, this model goes under the kitchen sink and connects to a separate faucet. This keeps the kitchen platform clean and premium-looking.

The product has a midnight black body, plastic build, and compact dimensions of around 27 x 41 x 42 cm. At around 13.5 kg, it feels like a solid purifier made for permanent installation.

This is a good choice for modular kitchens where design and space management matter.

Purification Performance

The AO Smith Z2+ Luxe uses 7-stage purification with RO filtration. It is designed to handle water with TDS up to 2000 ppm, which makes it suitable for many Indian homes using borewell or tanker water.

The Goodness of Copper feature is also useful for buyers who want mineral-enhanced water instead of plain RO-treated water. The taste feedback from users is mostly positive, especially from customers who mention that the water tastes clean and fresh.

Storage and Water Flow

This purifier comes with a 5-litre storage tank. For small to medium families, this should be enough for daily drinking water use. The flow rate is listed at around 15 litres per hour, which is decent for an under sink RO purifier.

However, if you have a very large family or very high water usage, you may want to compare it with bigger 8L or 10L storage purifiers.

Based on recent Amazon customer feedback, many users like the product for:
