The AO Smith Z1 water purifier has a larger 10 litre storage capacity compared to the 5 litre capacity of the AO Smith X2 model. The increased capacity makes the Z1 better suited for larger households and higher water consumption needs. A key advantage of the Z1 is its ability to dispense hot water on demand through three temperature settings – ambient, warm (45°C) and hot (80°C). The X2 does not offer hot water dispensing. Both models utilize UV+UF purification technology and have a 5 stage purification process to provide high quality, pure drinking water. Installation flexibility is a shared feature with options for wall mounting or placing on a table or countertop. The filtration capacity is 30 L/hr for both with a 0.5 L/min flow rate for quick purification. An attractive light effect on the Z1 model guides users at night and adds aesthetic appeal. Durable stainless steel storage tanks promote hygiene and allow water dispensing during power outages. The Z1 requires a minimum 20bps water flow otherwise a booster pump may be needed. It cannot connect directly to a tap or provide cool water. Hot water dispensing has a slight delay and annual maintenance charges are higher than the X2 model.

Comparison: AO Smith Z1 Vs X2 Water Purifier
1. Digital Display: The AO Smith Z1 model comes equipped with an intuitive digital display which presents information easily and clearly; unfortunately, this feature is absent on X2 models.
2. UV Lamp Change Indicator: The AO Smith Z1 model contains a feature to alert users when their UV lamp needs replacing, helping you keep track of your purifier’s maintenance schedule more easily. Unfortunately, however, this feature was omitted for their X2 counterpart.
3. Aesthetics: The AO Smith Z1 model features an elegant look with its glossy surface and light effects; adding elegance and distinction to your kitchen. In contrast, its counterpart, the X2, is sleek yet lacks this special effect.
4. Size: The AO Smith Z1 model stands out with its 10-litre capacity for more spacious households; in comparison, its more compact 5-litre counterpart makes the X2 suited to smaller living environments or limited kitchen spaces.
5. Maintenance Costs:
The AO Smith X2 water purifier, on the other hand, uses UV + UF technology to purify water. This model is designed for municipal water supply and is not suitable for borewell or tanker water. The annual maintenance cost for the AO Smith X2 is approximately ₹2,500 , depending on the usage and quality of the water.
| Feature | AO Smith Z1 | AO Smith X2 |
| Filter Replacement Frequency | 1 year (Sediment, Pre-Carbon, UV Lamp, UF Membrane) | 1 year (Sediment, Pre-Carbon, UV Lamp, UF Membrane) |
| Filter Replacement Cost (approx.) | ₹2500 | ₹2500 |
| Additional Maintenance (if any) | May require occasional cleaning of the hot tank | No additional maintenance |
| Total Annual Maintenance Cost | ₹2500 | ₹2500 |
6. Child Lock Safety Feature: The AO Smith Z1 model comes equipped with a child lock safety feature to avoid accidental burns or scalding in households where there are children present, ensuring greater household security. However, due to the lack of hot water dispensation capabilities on its X2 counterpart, this feature cannot be utilized as effectively.
7. Energy Efficiency: The AO Smith Z1 model consumes more energy due to its hot water dispensing feature which requires heating elements; this may contribute to higher electricity bills compared to its more energy-efficient cousin, the X2, which does not include this feature.
8. Installation Requirements: For hot water dispensing purposes, the AO Smith Z1 model needs a nearby electrical outlet while for the operation of its X2 counterpart, there are minimal setup requirements since no such outlet is necessary for operation.
9. Ease of Use: Both models have been created with user convenience in mind and feature simple setup options – whether wall mounting or countertop placement – making installation a snap. However, due to its digital display and UV lamp change indicator, its Z1 model has an edge in terms of ease of use.
