A. O. Smith Z8 vs Z9

In this post, I will be comparing two of the most advanced water purifiers offered by A. O. Smith in India. That is AO Smith Z8 vs Z9. Both these models have very similar specifications and they also look almost the same. So it is easy to see why this query gets asked multiple times on my blog.

But you need not worry. I will help you compare both these models in this article below.

Summary: Which model is a Better Buy?

If you do not wish to go through the details below and just looking for a recommendation, this is the section for you.

For most Indian households, this the product that I would recommend. This is the only model that you should consider (out of the two) if you have frequent power outages in your area. The same product is available on Amazon India too. Do click here to compare prices on both websites before you buy.

However, if you like advanced/nerdy features (which do not impact the water quality but are more premium features) and do not mind paying a bit extra, you can opt for this model of AO Smith. This model is good for people who have back power generators in their apartment/residential colony.

Do not forget to compare price on Flipkart for this model too.

Comparision – AO Smith Z8 vs Z9

As I said at the beginning of my post, both these products are very identical. However, there is one major difference between the two. This difference will help you make your purchase decision.

Also, while this post is aimed at comparing these two model. I have also taken the effort to go through the common features of both these models to help you understand if this is the right brand for your home.

I will start off comparing these two models with the help of the table below.

So, as you can clearly see that the major difference between AO Smith Z8 & Z9 is how they dispense water from the storage. Z8 using regular faucets/tap, while Z9 uses an automatic sensor.

While this may seem like a really good feature. It becomes a source of major inconvenience when there is no electricity at home. So even though the water purifier might be full with clean water, you cannot drink it as the sensor will not function when you have a power cut.

Hence, I recommend buying the Z8 for most households in India.

The drawback of Buying AO Smith A8 & A9

Since they are so similar, they also share their disadvantages. I would like to point out one major flaw in the product that I came across.

Be sure you are aware of this before you buy any of these products.

• You can get hot water from the purifier only if the tank inside is completely full. I don’t understand why it works this way since they have provided two different tanks for hot and cold water to be stored separately.
• To make matters worse, the water purifier only starts refilling once the water level in the cold tank drop below 50%
• So, let’s say, you filled a 500 ml bottle first. Now, you won’t be able to get any hot water. You will have to first remove 4.5 Liters of water, wait for the tank to refill and then you get some water to drink.

Apart from this drawback, both these products are absolutely fabulous.

This brings me to the end of my article comparing AO Smith Z9 & Z8. I hope I was able to help you select the right product for your home. So, which one did you decide to buy? Have you bought any other A. O. Smith products in the past? If so, how has been your experience so far?
