There is one question every Indian family asks before buying an RO purifier: “How much water will it waste?” You see it on the kitchen floor when the little reject pipe keeps running into a bucket. Eureka Forbes built the Aquaguard Delight Aquasaver around that exact worry. The name itself is a promise: it saves water.
I looked at this purifier the way I look at any appliance that goes into a home kitchen for the next five years: what is inside, what does it cost to run, who is it really for, and where does the marketing run ahead of the facts. Below you will find the full picture in simple English, with a few calculators so you can test it against your own water and your own family.
*“Up to” figures are measured under the maker’s standard test water. Real life depends on your water. More on this below.

SECTION 01Design and First Look
The Delight Aquasaver is a wall-mounted unit made of food-grade ABS plastic, about 32 cm wide, 27 cm deep and 48 cm tall, and it weighs close to 7 kg. It is meant to hang on the kitchen wall near a water point and electric socket, with a small tank inside. The shape is a tall rectangle with a glossy front, and it looks tidy, more like a modern appliance than the old bulky purifiers.
It is not the smallest purifier you can buy, but it does not eat counter space because it sits on the wall. The big thing to plan for is a spot that is close to a tap or inlet, has a plug point, and allows a drain pipe for the reject water. Installers handle all that, but you should know the layout before they come.
The front has LED indicators for the tank level, service reminders, filter warnings and errors, and the machine shuts itself off automatically when the tank is full. There is no smart screen and no live TDS display. That keeps it simple, but it also means you cannot see your water quality on the machine. I recommend buying a cheap hand TDS meter for a few hundred rupees. You will see why in a moment.

SECTION 03The 9 Stages, Explained in Plain Words
“9-stage purification” sounds impressive, but what does each part do? Think of the purifier as a security checkpoint at an airport: each gate catches a different problem. Brands count stages differently, so treat the number as a marketing label. What matters is the type of technology inside.
The Mega Sediment Filter
This is a bigger external pre-filter that sits before the main body. In India, water often carries mud, rust or fine sand, especially from borewells or after the first monsoon rains. If this dirt enters the inner filters, it chokes them early. The Mega Sediment Filter is there to take that first hit, so the expensive RO membrane lasts longer. It is also something you replace separately, so ask the installer how often.
Nanopore RO
RO stands for Reverse Osmosis. Imagine pushing water through a cloth with microscopic holes. Water molecules pass through, but dissolved salts, many heavy metals and other bigger particles are held back and washed down the reject pipe. This is the stage that handles hard, salty and borewell water, and it is the reason RO is the standard in places with high TDS.
UV and UF
UV uses ultraviolet light to disturb the DNA of germs so they cannot multiply. UF (ultrafiltration) is a fine hollow-fibre mesh that blocks bacteria, cysts and tiny suspended particles, and it is a useful second barrier if something goes wrong upstream. Neither of them removes dissolved salts, which is why RO is in the middle of the line.
Mineral Charge (MC)
RO takes out almost everything, including the good minerals. The Mineral Charge cartridge puts back some calcium and magnesium, which the brand says improves taste. We will come back to this in section 06.
SECTION 04Do You Even Need RO? Try the TDS Checker
This is the part most sales people skip. TDS stands for Total Dissolved Solids, a number (in ppm or mg/L) that shows how much dissolved material is in your water. The Indian drinking water standard (IS 10500) treats up to 500 as acceptable, and up to 2,000 as the upper limit only when no better source exists. Very low TDS water usually does not need RO at all, and running RO on it just wastes water and removes useful minerals.
Use the checker below. Measure your tap water with a TDS meter (or ask your local supply board), and choose your water source.
My honest take: this purifier is strongest for the 500 to 1,000 ppm range, the typical borewell and tanker situation in many Indian cities. That is where RO is needed, and where a water-saving design pays off most.
SECTION 05The “Aquasaver” Claim: How Much Water Does It Waste?
Every RO purifier makes reject water. The question is how much. A plain old RO might send 3 to 4 litres to the drain for every litre of clean water, meaning only about 20 to 30% of the water is recovered. The Aquasaver design aims higher. The brand says “up to 60%” recovery, which would mean about 0.67 litres of reject water for each litre of drinking water.
But here is the catch, and I want to be fair. The brand’s wording on different pages is not consistent. Some say “60% higher recovery”, and some say “up to 60% water savings”. These are different things. Recovery also drops when your TDS is high, because the membrane has to work harder. So use the calculator with both a hopeful and a careful number.
Play with the numbers. Even in the careful case, you can see the saving adds up over a month. Imagine a typical flat with two buckets of reject water every day: that is what this number translates to. If you can reuse the reject water for mopping, washing the car or watering plants, the real waste is even smaller.
SECTION 06Mineral Charge, Taste and Water Quality
RO water can taste flat. The mineral charge stage is the brand’s fix. By putting back some calcium and magnesium, the water is meant to taste a little softer and less “empty”. Many households like this, especially if they used to find RO water dull. It will not make water taste like mineral water, but the difference between a plain RO glass and a mineral-charged one is something you can notice if you pay attention.
On purity, the brand claims that Nanopore RO reduces pesticides, microplastics, and metals like lead, mercury, cadmium and arsenic. I have not seen independent lab reports for this model, so please read these as the brand’s claims. The honest way to check is to use a TDS meter. A working RO should bring a 600 ppm tap down to well under 100 ppm at the outlet, though a Mineral Charge stage will lift the number a little, and that is normal.
SECTION 07Filter Life, Service and Running Cost
The 2-year claim
The headline promise is a 2-year filter life. In reality, this is an “up to” number tested with clean standard water (TDS of about 1,000 ppm or less). If your water is muddy, very hard or very salty, or if you use more than the average, the filters will wear out sooner. One review also listed 6 to 8 month replacement intervals for some parts, and the Mineral Charge cartridge is a special part that costs more than a normal one. The pre-filter and sediment parts are the ones most likely to need early replacement.
Service plan
In the first year, the plan covers installation, 2 free cleaning services and unlimited repair visits, according to the listings. After that you will need an annual maintenance contract (AMC) or pay per visit. Eureka Forbes has a large service network in India, which is one of its biggest strengths, but service quality depends on your city and area. Ask neighbours who own Aquaguard what their service experience has been.
What will it actually cost over 3 or 5 years?
The purchase price is only the start. Use the calculator to see the total. I left the price blank on purpose because Amazon prices change often. A price tracker showed the listing between about Rs 8,500 and Rs 15,000 over time. The “MRP” of Rs 26,500 is a list price that few people ever pay, so do not be impressed by the big discount percentage. Compare the real selling price.
Electricity is small. At about 45 W while running, and only for a couple of hours a day, you are looking at a few hundred rupees a year at most. The bigger costs are the filters, the Mineral Charge cartridge and the yearly service.
SECTION 08Installation and Daily Use
Installation is done by the company’s technician and is free in the first year. Tell them where the water line, power socket and drain are. Ask them to show you how to open the cover and which light shows what. Keep the invoice, the warranty card and the service number (18602661177 is listed on a sister model’s page; confirm it on your invoice).
- Water pressure: RO needs steady inlet pressure. If your tap pressure is low, or the water comes from a tank on the roof, ask whether a booster pump is needed. The model pages do not state a pressure rating, so ask the installer.
- Power cuts: The unit needs continuous electricity to run the pump and UV. During a power cut, you can still draw water from the tank, but it will not refill until power returns.
- Capacity: The tank holds about 6 litres, and refills at around 20 litres per hour. For a family of 4 to 5 that is usually fine. For 6 or more people, or for a house where many guests visit, the tank may feel small during busy hours.
- Daily habit: Do not leave stored water for many days if you are away. Draw out the first glass after a holiday, and let the tank refresh.
SECTION 09My Rating
A well-featured RO+UV+UF purifier with a water-saving design, a solid service network and a good mineral stage. It loses points for inconsistent claims across pages, a small tank, and hidden ongoing costs.
SECTION 10Pros and Cons
- RO + UV + UF with Mineral Charge in one unit
- Water-saving design, with a brand claim of up to 60% recovery
- External Mega Sediment Filter protects the inner filters
- Works for borewell, tanker and municipal water (check your TDS)
- Up to 2-year filter life under standard test water
- Large service network, free installation and 2 free cleanings in year one
- Wall-mount, compact, and LED alerts for service and filters
- Brand numbers differ across pages (filter litres, TDS, recovery)
- The 6 L tank can feel small for a big family
- The 2-year life needs fairly clean input water
- Mineral Charge cartridge and sediment filter are extra costs
- No live TDS display or smart screen
- Needs electricity and steady water pressure
- The huge MRP discount is more marketing than saving
SECTION 11Who Should Buy the Aquaguard Delight Aquasaver?
Buy it if you:
- Have borewell, tanker or hard municipal water with TDS above 500 ppm
- Are tired of RO machines that waste a lot of water
- Want a trusted brand with doorstep service across India
- Have a family of 3 to 5 people
Think twice if you:
- Have low-TDS water (under about 200 ppm), where UV+UF alone may be enough
- Live in a large joint family that needs plenty of water at once
- Have very low water pressure and no way to add a pump
- Live in an area where service visits are slow or unavailable
SECTION 12Tips to Get Longer Life From It
- Measure your TDS. A TDS meter costs very little and tells you if the purifier is working and when the membrane may be tiring.
- Do not skip the sediment filter change. It protects everything behind it.
- Reuse the reject water. Mopping, plants, toilets and cars. Use a clean bucket and cover it.
- Keep the area dry and clear. The vent and the drain pipe should not be bent or blocked.
- Switch off if you are away for long. Flush the first few glasses on return.
- Use the service visits. The 2 free cleanings in year one are worth booking, not skipping.
SECTION 13Frequently Asked Questions
Is the Aquaguard Delight Aquasaver good for borewell water?
Yes, that is its strongest use. RO is built for hard and salty water. Check your TDS first, and ask the installer about the right setup if your water is very muddy or has high TDS.
Does it really save 60% water?
The brand says up to 60% recovery or savings, but the wording differs across pages and real results depend on your water. Use the calculator in section 5 to test both a hopeful and a careful case.
What is MC Tech?
It refers to the Mineral Charge technology, a stage that adds back calcium and magnesium after RO to improve taste.
What is the tank size?
About 6 to 6.2 litres, depending on the page. It refills at about 20 litres per hour.
How long do the filters last?
The brand says up to 2 years under standard test water. Some parts, like the sediment filter, may need earlier changes. Hard, muddy or high-TDS water shortens the life.
What does the warranty cover?
There is a 1-year warranty. The first-year service plan includes installation, 2 free cleaning services and unlimited repair visits, as listed. Read the exact terms on Amazon and keep your invoice.
Does it need electricity?
Yes. It needs power for the pump and the UV stage. You can draw water from the tank during a short power cut, but it will not refill until the power is back.
Can it be placed on a table?
The listing describes it as wall-mounted. Some sister models allow table-top use, so do not assume this, and confirm with the seller.
FINALVerdict: Should You Buy It?
The Aquaguard Delight Aquasaver is a strong, sensible RO+UV+UF purifier for families who deal with hard or borewell water and want to waste less of it. The Mega Sediment Filter, the Mineral Charge stage, and the big Eureka Forbes service network make it an easy and safe pick.
The weak spots are mostly about clarity. Different pages give different numbers, the 2-year filter life depends on clean input water, and ongoing costs like the mineral cartridge and annual service are easy to forget. And if your water is already low in TDS, you probably do not need RO at all.
My advice: measure your water first. If it is above about 500 ppm and you have 3 to 5 people at home, this is a very good buy at around 7.4 out of 10. Compare the actual selling price, not the MRP, before you order.
