AO Smith Z8 vs X8 – What’s the same?
Type & Filtration
AO Smith Z8 and the X8 are electric water filters that use RO and SCMT purification technologies to make tap water or groundwater drinkable again. Both devices feature an 8-stage filter system that removes viruses, bacteria, dust, lead and other toxic particles from drinking water.
Material
Both water filters are made of food-grade ABS plastic, which is perfectly safe to use for both adults and children. The plastic used in this filter is not water-soluble like other cheap devices on the market to keep the whole process hygienic and clean.
Pressure Range
You can install this water purifier in any home or a tall building as it is designed to adapt to pressure. Both units maintain a pressure of 7-30 PSI, so you don’t need to add any other accessories before installing the water purifier as they both have a built-in pressure control system.
AO Smith Z8 vs X8 – What’s so different?
Design
Each AO Smith water filter has a unique design that changes everything from the outside. The AO Smith Z8 has a black finish with a silver top, while the second device has a white frame. Also, the Z8 is equipped with a significantly wider display and two water jets make the overall design look better, which the X8 simply can’t match.
Capacity
There is a slight difference between the AO Smith Z8 and X8 water purifiers. The Z8 comes with a capacity of under 9.8 litres, while the X8 only offers 9 litres of water storage tank. This lets you filter and stores more water in Z8, making it better for large families who need more fresh and filtered water every day.
Power & Hot water
Although the AO Smith X8 is an older version, you get a more economical range of performance with this device. The Z8 uses more energy because it is equipped with a heating coil that constantly regulates the water temperature, increasing energy consumption.
Weight
The AO Smith X8 is 1.3 kilograms lighter than the Z8 water filter. So, installing the X8 is a lot easier because you have to lift less weight to mount it on the wall. The water filter can also be placed on the table, but we don’t recommend this unless you want to deal with water stains on furniture.
Night Assist
The Night Assistant was first launched by AO Smith, which uses a small LED light to help you drink water at night. The lights turn on automatically at night, so you don’t have to look for a light switch in the kitchen before drinking water. This night light is only available on the AO Smith Z8, so people who have a habit of getting up at night to drink water can choose this device.
