1. Aquaguard Aura

If you ask Indians to name a water purifier brand, then 9 out of 10 people will say Aquaguard. And, that’s the legacy they have in India. In Fact, according to our retail partners, all the top 3 highest selling models in their shops are made by Aquaguard.

Aura is their latest premium flagship water purifier series that was launched in the year 2020 during Diwali.

It is also one of their water purifier series that comes with copper infusion and UV e-boiling technologies.

At the time of writing this article, Aquaguard Aura is available in multiple variants with RO and without RO. In this article, we’re going to look at the model with UV+UF purification technologies.

What are the Specifications of Aquaguard Aura?

Technology	UV+UF
No. of Stages	6
Storage Capacity	7 L
TDS	<200 ppm
Flow Rate	33 LPH
UV Lamp	11W
Warranty	1 Year

How’s the Design and Build of Aquaguard Aura?

Aquaguard Aura has a dual color tone with black and copper colors. It is not only aesthetically pleasing design but also complements your designer kitchen.

All the parts of the water purifier are made up of engineering grade plastic that are non toxic and food safe.

Because of full plastic construction, the overall weight of the purifier is well under 8Kg. It enables the model to be wall mounted easily without exerting too much pressure.

It comes with a stylish tap with metallic copper finish. Also, the striped water level indicator at the top adds to the overall look of the purifier.

Based on your preference, you can either wall mount or place it on the table. But, we prefer wall mounting because it ensures safety and improves the overall look as well. 

The power button is placed towards the right of the metallic tap. LED indicators are embedded into the button and different color lights are programmed for different scenarios.

How does Aquaguard Aura remove impurities from water?

Aquaguard Aura comes with a 6 stage water purification process to remove chemical and biological impurities.

The filters include I-Filter, Chemi Block, UF membrane, Mineral Guard, UV chamber and Copper Cartridge.

The I-Filter is responsible for removing all the fine suspended particles like dust, sand, small stones, dirt, etc.

Then the water is passed into the Chemi Block where excess chlorine and organic impurities are removed to improve the taste and odour of the water.

The third stage is Ultrafiltration or UF, where the water is passed through a afine membrane that traps all the physical, chemical and biological impurities that escaped the previous stages.

Then the Mineral Guard ensures that the water has all the required minerals like calcium and magnesium in correct proportions. 

Mineral Guard is actually a process meant for RO purifiers and not necessary for UF+UF models. It is because no minerals are lost during the UV and UF processes.

And then the water is sent into the UV chamber where it is subject to Ultraviolet radiation that kills all the bacterias and viruses.

The final stage is the Active Copper Cartridge, the title feature of this model. It infuses the right amount of the copper ions in the water before dispensing so that you get 100% healthy copper infused drinking water.

What Benefits do you get from Aquaguard Aura?

Aquaguard Aura features a storage tank with 7 L capacity so that you get uninterrupted purified drinking water supply even during power cuts or failures. 7 Litres is sufficient for families with 4 to 5 members.

The most prominent feature in Aquaguard Aura series of water purifiers is the presence of Active Copper Technology.`

Since copper is known to have good health benefits, the Active Copper Technology ensures every drop of water is infused with the right amount of copper ions at the end before dispensing.

Aquaguard Aura comes with a complimentary one year warranty for the entire product. But, keep in mind that warranty does not cover filter life. 

Based on the lab tests, the average life of the internal filter is 6000 to 8000L depending on the water source. 

Since it is a UV+UF water purifier, the input water TDS level must be less than 200. If your input water has TDS greater than 200 you should purchase the RO+UV version of Aquaguard Aura.

When the filter reaches near to it’s end of life, Aura will continuously make a beep sound to let you know that it’s time to replace the filter. If you fail to replace filters, it will stop dispensing water when the filter expires.

What are the Positives of Aquaguard Aura?

• Advanced 6 stage purification
• 7 L water storage tank
• UV+UF technology
• Copper infusion
• Mineral Cartridge
• UV e-boiling for 20 minutes
• 33 LPH flow rate
• Filter and UV lamp change alert
• Water level indicator
• Excellent design and build
• 1 year warranty

What are the Negatives of Aquaguard Aura?

• Mineral guard is not necessary for UV+UF purifiers
• Slightly expensive
• Average life of internal filter is less
• Dead bodies of bacteria and viruses are not removed
• Poor service and installation in many localities

Verdict: Should you buy Aquaguard Aura?

If you are looking for an aesthetically pleasing water purifier with features like copper infusion and Mineral Guard, then Aquaguard Aura stands tall among all the UV+UF purifiers in this range.

2. AO Smith Z1

A O Smith is an American multinational corporation that makes everything from bombs to water purifiers! In fact, they were the largest bomb manufacturer during World War 1(crazy!).

In 2010, they launched their water heaters and purifiers in the Indian market made from their manufacturing plant in Bengaluru.

Because of the unique designs and build quality, their products gained traction among the upper middle class and rich people. And, AO Smith is continuing the streak till today.

AO Smith Z1 is the only water purifier in this range from a reliable brand that has the ability to dispense hot water.

So, if you are looking for a UV water purifier that can dispense hot water then this is the best option you have. 

Let’s have a detailed review of AO Smith Z1 with the help of its features and benefits so that you can easily decide whether it will suit your needs or not. 

What are the Specifications of AO Smith Z1?

Technology	UV+UF
No. of Stages	5
Storage Capacity	10 L
TDS	<200 ppm
Flow Rate	30 LPH
UV Lamp	11W
Warranty	1 Year

How’s the Design and Build of AO Smith Z1?

AO Smith Z1 features a unique and bold design compared to all other models in this category.

Because of its large 10 litres storage tank, the overall size of this water purifier is quite big with a height and width of 44 and 39 cm respectively. So, before purchasing make sure that it will fit in your designated spot.

Depending on your preference, it can be either wall mounted or placed on a table. In both ways, it looks awesome.

All the filters are placed at the bottom half of the purifier and the storage tank is at the top.

You can fill the water bottles handsfree by placing it on the bottle guards at the front. The bootle guard is tall so that you can easily fill even 1.25L bottles.

Also, the notification icons are placed at a convenient place above the bottle guard and dispenser taps.

The glow effect in the design ensures that you can easily find the water purifier even in the darkness. We found it very useful, especially at night.

How does AO Smith Z1 remove impurities from water?

AO Smith Z1 features a 5 stage procedure to remove the contaminants from the input water. 

The 5 stage processing includes passing the input water through a sediment filter, fine sediment filter, carbon block, UV chamber and finally a UF membrane.

The input water may have suspended particles like sand, small stones, cysts, etc. All these will be removed by sediment filters and fine sediment filters.

After that, an activated carbon filter is employed to remove all the waterborne pathogens. Additionally, it removes hard metals like arsenic, mercury, etc to an extent.

Once the water is filtered by a carbon filter, it is passed to a UV chamber where a 11 Watt UV lamp is used to kill the bacterias and viruses.

Then water is passed through the Ultrafine membrane to remove the dead bodies of bacterias and viruses that were killed in the UV treatment. Also, the microorganism that escaped UV will be filtered here.

What other Benefits do you get from AO Smith Z1?

As I already mentioned, AO Smith Z1 is the only water purifier in this range that can dispense hot water. In fact, this is the title feature of this model.

From this model, you can get water in three temperatures: normal, warm and hot. 

Normal water will be at the same temperature as your input water source. Warm water will be at 40 ^oC and hot water at 80 ^oC. Warm water is suitable for drinking purposes whereas hot water is ideal for cooking.

In order to prevent overheating, this machine comes with an emergency power cutoff circuit which gets activated if the internal temperature reaches 90 degrees.

One problem with hot water dispensing is that you won’t get hot water until the tank is full. So, in order to get hot water you might have to wait up to 10 minutes depending on the water level in the storage tank.

The top notification panel consists of multiple LED indicators with different icons for easier understanding. 

The notifications include tank full, purification on, UV lamp life alert, filter change alert, hot water availability and a dual digit display to show the water temperature.

Another useful feature is the presence of child lock in the hot water faucet so that your child won’t accidentally dispense hot water and get burns.

What are the Positives of AO Smith Z1?

• 5 stage process with UV & UF
• Hot and ambient water dispensing
• 10 L storage tank
• High flow rate of 30 LPH
• UV lamp life alert
• Filter kit change alert
• Digital display
• Child lock for hot water faucet
• Colorful LED indicators with icons
• Great design and build
• Wall/Table top mountable
• 1 year warranty

What are the Negatives of AO Smith Z1?

• Expensive for a UV purifier
• No free installation
• Not instant hot water
• Less serviceable areas
• Poor service recorded in many localities

Verdict: Should you buy AO Smith Z1?

As I already said, if you are looking for a UV water purifier with hot water dispensing options, then AO Smith Z1 is probably the best choice to go with.

And the presence of an advanced 5 stage purification process with sediment filters, carbon filter and UF makes this an excellent choice for people in areas where the TDS level is less than 200.

3. Kent Maxx

Kent is one of the market leaders of water purifiers in India. In fact, they are the customer favourite in the northern part of India compared to other brands.

They have products to reach all the categories of people from lower middle class to upper middle class and also the affluent who want luxury in everything they buy.

Being cheap doesn’t mean it does not perform well. It is actually a no nonsense kind of purifier that does not come with any ground breaking technologies. Just a simple machine to do the task without any fluff.

All the filters are at the back side, the storage tank is at the front and the water inlet pipe is from the side.

As I already said, it has a transparent water storage tank at the front and you can easily monitor the water level without any indicator.

It’s definitely not the most beautiful water purifier compared to a few other models in this list, but the blue and white dual tone colour is a beauty on it’s own.

How does Kent Maxx remove impurities from water?

Kent Maxx comes with a simple and straightforward 3 stage water purification mechanism that ensures 100 percent pure drinking water.

It has an activated carbon pre-filter that improves the taste and reduces organic materials that cause bad odour.

Then the water is sent to the UV chamber where a 11W UV lamp is employed to kill all the microorganisms like bacterias, viruses and other cysts.

Also, the storage tank is detachable. So, it makes the cleaning process very easy compared to other purifiers in this list.

In order to help you change filters and UV lamps at the correct time, it has an internal computer controlled filter change beep alarm.

It also comes with two notification LEDs for power On and purification On indications.

If your input water has a lot of sediment impurities like sands, clay, etc then you may have to purchase an external pre-filter to maximize the UF membrane life.

5. Aquaguard Deluxe UV+

It is no surprise that another model from Aquaguard got a spot in our list of best UV water purifiers.

Aquaguard Deluxe UV+ is a unique model compared to all others in the list. It does not have a storage tank, that means you should purchase this model only if you get unlimited supply of water 24/7.

Also, it is a UV only model with no UF filtration. A lot of features in this model are similar to the Aquaguard Aura series of premium water purifiers.

Let’s see how this model purifies water when compared to other models in this list.

What are the Specifications of Aquaguard Deluxe UV+?

Technology	UV
No. of Stages	4
Storage Capacity	–
TDS	<200 ppm
Flow Rate	120 LPH
UV Lamp	8W
Warranty	1 Year

Aquaguard Deluxe UV+ comes with a rectangular design front with a bottle guard at the center.

It is a very simple looking weather purifier with black and white color tones. The whole body of the purifier is coated with white color and the top strip and bottle guard base is coated with black to achieve contrast in the design.

Since it does not have a storage tank, the overall physical footprint is smaller compared to other models. The dimension of this model is 23.2 x 31 x 41.8 cm (LxWxH), so make sure that you can fit in the designated spot before purchasing.

Also, it weighs only 4.2Kg and the lack of storage tank makes it very easy to wall mount.

Build quality of Deluxe+ is also excellent as expected from a reputable brand like Aquaguard. The high quality food grade plastic ensures that the water is hundred percent safe to consume.

How does Aquaguard Deluxe UV+ remove impurities from water?

Similar to all other models, Aquaguard Deluxe also comes with a multi stage water purification process to remove the contaminants from the water.

Generally, the tank less water purifiers have only UV treatment. But Aquaguard Deluxe UV+ comes with a 4 stage purification process.

The filters in the purification include I-Filter, Chemi Block, Mineral Guard and UV chamber.

The I-Filter is responsible for removing all the fine suspended particles like dust, sand, small stones, dirt, etc.

Then the water is passed into the Chemi Block where excess chlorine and organic impurities are removed to improve the taste and odour of the water.

Once the water is out of Chemi Block, the Mineral Guard ensures that it has all the required minerals like calcium and magnesium in correct proportions. 

After that, the water is passed into the UV chamber where an 8W Ultraviolet light is used to kill all the bacterias and viruses.

What Benefits do you get from Aquaguard Deluxe UV+?

It comes with an electronic monitoring system that detects if there’s any issue with the UV lamp. Also, the UV lamp and filter change alarm notifies you when to change them.

Since it does not have UF filtration, the purified water flow rate is very high, a whopping 120L per hour.

Also, the UV e-boiling feature delivers the water similar to the ones we get after 20 minutes of normal boiling.

The auto shut off feature in this machine is very handy if you are someone like me who forgets to turn off things quite often after using. If the UV lamp is not in use for 10 minutes, then the machine will turn off the UV lamp to save power and life of the lamp.

Also, to improve the user experience there are multiple LED indicators for displaying different statuses and errors.

Depending on the input water quality and TDS levels, the internal filters and UV lamp will have a lifespan up to 6000 Litres.

Even though Aquaguard Deluxe UV+ comes with a multistage water purification system, it is ideal for input sources with TDS less than 200 only. Also, it does not have a storage tank. So, places with 24/7 water supply are necessary.

None of the states in India except Kerala provides unlimited supply of pre-treated municipal water 24/7 with TDS less than 200 to 90% of the localities. Also, if you live in a township with their own water softening plant with 24/7 supply, then you can go with this model.
