Mi Smart Water Purifier (RO+UV)
If there was one product for which we have waited so eagerly to review, it has to be the Mi Smart Water Purifier.
The water purification market has not seen any groundbreaking innovation for quite some time and we were fed up with the same copy-paste products which offered very little innovation.
And we are glad Mi has finally launched the Mi Smart Water Purifier in India.
Let’s see why we think that this Smart Water Purifier has the potential to change the Indian water purifier market. Read this Mi water purifier review to know all the features, pros, cons and the Mi water purifier price.
The Mi Smart Water purifier with its minimalistic design makes your kitchen look stylish and smart.
The biggest USP of this water purifier is evident in its name. This is a smart water purifier, and what that means is this Mi water purifier can be remotely controlled and monitored with the help of Mi Home app. Mi Home app is a free mobile application that is available on both Android and iOS.
With the help of the Mi Home app, you will be able to monitor and control the water purifier in real-time.
The Mi Home app shows you the exact TDS level of the input water and the purified water, water level in the storage tank, UV sterilization status and the life of each filter in real-time. The app also informs you when the filters need to be replaced.
Key Features
- 5-stage purification with RO and in-tank UV
- Change the filters by yourself in under 30 seconds without the help of a technician
- Real-time display of TDS level of both the incoming and the purified water
- Monitor and control the water purifier in real-time through the Mi Home app
- The In-Tank UV purification removes the slightest possibility of microbial contamination
- Storage tank of 7 liters with an automatic water level detector
Another interesting innovation that addresses the biggest pain-point of most water purifier users in India is the ability to replace the water filters yourself. Till now, users had to call a trained professional every time the filters needed a replacement. With Mi Water Purifier this is guaranteed to change forever.
This smart purifier gives you the power to change the water filters yourself. The filter replacement takes just 30 seconds and does not require any tools like screwdriver, pliers or anything else.
Mi Smart Water Purifier gives you complete freedom from the vicious circle of costly annual maintenance contracts. The Mi Home app automatically notifies you when a filter needs to be replaced and you can easily order a new filter through the app.
The following official video from Mi shows you how you can easily replace the filters in just 30 seconds.
App control, DIY filter replacement, great design, all this sounds good but what about the purity of water. Because no matter how smart a water purifier is, it is only as good as the purpose for which it is primarily used i.e. the purification of water.
Mi Smart water purifier features 5-stage purification that includes both RO and UV. The thing that we like the most is, this water purifier does not feature any unnecessary purification stages. Recently we have seen a trend where some water purifier brands indulge in marketing gimmick by adding unnecessary filters in order to increase the number of purification stages.
Mi Smart Water Purifier features only 3 filters.
In the first and the second stage, a PPC (Polypropylene Cotton + Activated Carbon) filter traps all the large visible impurities and adsorbs residual chlorine, color, odor, and organic impurities.
In the third stage, an ultra-fine RO membrane, with a pore size as small as 0.0001 micron, filters out all the dissolved solids, heavy metals, and disease-causing micro-organisms like bacteria and viruses.
In the fourth stage, the PAC (Post Activated Carbon Filter) filter absorbs the remaining odor and organic impurities. It also improves the taste of the purified water.
In the fifth and the last stage, the in-tank UV light kills bacteria with up to 99.99% efficiency. And the water in the 7-litres storage tank is automatically disinfected after every 4 hours for a full 25 minutes. This eliminates any possibility of microbial growth in the stored water.
But all the smart features, like real-time TDS monitoring, real-time filter life and other information and alerts that are available through the Mi Home app will not work if you do not have Wi-Fi connectivity at your home.
The Mi Purifier does not feature any way to retain or add back the essential minerals lost during RO purification. Therefore, like any other RO water purifier, Mi Smart Water Purifier may not be suitable for your home if the TDS level of incoming water is already low.
Frequently Asked Questions (FAQs)
The ratio of pure water and wastewater is about 1:2 which means for every 1 litre of drinking water there will be 2 litres of wastewater. This is better than the average RO water purifiers which waste around 3 litres of water for every 1 litre of purified water.
The filter life depends on input water quality and your drinking water consumption.
Below is the average life of all the filters as provided by Mi.
PPC filter: Up to 1 year ‘or’ 10, 000 litres of tap water
RO filter: Up to 1 year ‘or’ 3,600 litres of pure water
PAC filter: Up to 1 year ‘or’ 3,600 litres of pure water
PPC Filter (Polypropylene Cotton + Activated Carbon) – Rs. 1,299
PAC Filter (Post Activated Carbon Filter) – Rs. 899

The filters can be bought directly from the Mi Home app. You can also buy the filters from the official website Mi.com, and authorized Mi stores.
Mi Smart Water Purifier does not come with any pre-filter. However, we recommend installing a Pre-filter, especially in the case of groundwater. Pre-filter increases the life of internal filters.
You can buy the pre-filter at extra cost during installation or after installation by calling their customer support. The cost of pre-filter, housing, and valve are as given below:
Mi Pre Filter Housing – Rs. ₹599
Mi Spun Filter – Rs. ₹149
Mi Three Way Valve – Rs. ₹299

Request to review your comment. No where it is said that drinking water TDS level should be only 70-80 it is about the dissolved solids if they are less than 300 it’s ok for drinking. Any purifier in world will remove all minerals irrespective of its use to us.
I don’t recommend this product. I have purchased Mi RO in the first sale just because MI has been a very trusted brand now.
I have purchased it on 09/30 from MI Store.
I got this installed this dated 10/14/2019 at my location Gurgaon.
After 2 days of using it, I noticed that Tap water TDS was 181 PPM and after purifying water TDS is 4 PPM only.
When I researched about it on google, 4 PPM water is not at all safe of drinking and it should be more than 70-80 PPM.
I called the person who has installed it and as per him this is automatic and he won’t be able to increase the TDS level as other RO’s do.
Please don’t waste your hard-earned money
