DIY filter replacement In Mi Smart Water Purifier

One of the best features that MI Smart water purifier brings on the table is self filter replacement finally you don’t need any technician to replace your filters and pay them the service fee it is very easy to change the filter in water purifier you can follow these steps shown in the video below and you will be amazed to see how easy it is and how well Xiaomi has designed this specifically India Xiaomi has done a good job in the department.

This smart water purifier from Mi gives you the ability to change the water filters yourself. The filter replacement takes just 30 seconds and does not require any tools like a screwdriver, pliers, or anything else.

Mi Smart Water Purifier gives you complete freedom on the vicious circle of costly annual maintenance contracts. The “Mi Home app” automatically sends notifications to you when any filter needs to be replaced and you can easily order a new filter through the app itself.

But all the smart features in Mi Water Purifier, like real-time TDS monitoring, real-time filter life, and other information and alerts available through the Mi Home app, will not work if you don’t have Wi-Fi connectivity at your home.

App control, DIY filter replacement, great design, and awesome build quality all this sounds extremely good but what about the water purification. Because at the end of the day no matter how smart a water purifier is, it is only as good as the purpose for which it is primarily made for i.e. the purification of water.

5-Stage Purification On Mi Smart Water Purifier

Xiaomi Mi Smart water purifier comes with a 5-stage purification process that includes both RO and UV. I like it the most because the water purifier does not come with any unnecessary purification stages. Recently, we have seen a trend in which some water purifier brands are using in marketing as a gimmick by adding unnecessary filters to increase the number of purification stages and fool the customers.

Mi Smart Water Purifier comes with 3 filters

PAC Filter

PPC (Polypropylene Cotton + Activated Carbon) filter traps all the large visible impurities and adsorbs residual chlorine, color, odor, and organic impurities. This is the first and second stage towards purifying the water.

RO Membrane Filter

This is the third stage where, an ultra-fine RO membrane, with a pore size as small as 0.0001 microns, filters out all the dissolved solids, heavy metals, and disease-causing micro-organisms like bacteria and viruses and clean the water further.

PAC

This is the fourth stage where the PAC (Post Activated Carbon Filter) filter absorbs the remaining odor and organic impurities. It also improves the taste of the purified water that we are habitual without that taste you will feel that water is not purified.

UV Purification

This is final so-called the fifth stage and the last stage, the in-tank UV light kills bacteria with up to 99.99% efficiency. And the water in the 7-liters 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.

The Xiaomi Mi Smart water Purifier doesn’t have 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 tap water is already low and it is drinkable.

Xiaomi Mi Smart Water Purifier CONS

  • Offers no way to retain or add-back essential minerals lost during RO purification
  • Not suitable for low TDS water (below 500 mg/L)
  • Needs Wi-Fi connectivity for control and monitoring through app

Frequently Asked Questions (FAQs)

1. What is the recovery ratio in Mi Water Purifier?

The ratio of pure water and wastewater in my testing is about 1:2 which means for every 1 liter of drinking water there will be 2 liters of wastewater. By the way, this is way better than the average RO water purifiers which waste around 3 liters of water for every 1 liter of purified water.

2. When should the filters be replaced?

The filter life totally depends on input water quality and your drinking water consumption.

Below I have listed the average life of all the filters as provided by Mi.

PPC filter: Up to 1 year ‘or’ 10, 000 liters of tap water
RO filter: Up to 1 year ‘or’ 3,600 liters of pure water
PAC filter: Up to 1 year ‘or’ 3,600 liters of pure water

3. What is the cost of filters of Mi Water Purifier?

  1. PPC Filter (Polypropylene Cotton + Activated Carbon) – Rs. 1,299
  2. PAC Filter (Post Activated Carbon Filter) – Rs. 899
  3. RO Filter/Membrane – Rs. 1,799

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.

4. Is there any pre-filter provided with Mi Smart Water Purifier?

Xiaomi Mi Smart Water Purifier does not come with any pre-filter. However, I 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 Xiaomi customer support. The cost of pre-filter, housing, and valve are listed below:

  • Mi Pre Filter Housing – Rs. ₹599
  • Mi Spun Filter – Rs. ₹149
  • Mi Three Way Valve – Rs. ₹299
