Confused about how to select the ideal water purifier option for you and your family? Don’t worry; read this space to address all your concerns.
When deciding upon the type of water purifier to buy for home use, many people are unsure where to begin. We are happy to provide a step-by-step guide to help you find the right water purifier for your family and home.
But first, some basics-
Every home has access to a maximum of 4 forms of water supply:
1. Municipal water supply
2. Borewell
3. Hand pump
4. Water tanker
Each source or a combination of many sources will have varying TDS levels (Total Dissolved Solids), which is the first aspect that you need to determine, according to which you can move on to the next step.
Total Dissolved Solids (TDS) refers to the minerals, salts, metals, etc. dissolved in water. It is measured in ppm (parts per million)
Hardness is the measure of dissolved calcium and magnesium in the water, while TDS is a measure of all dissolved solids. Hardness is a part of TDS, so the more the hardness of water, the more the TDS will be.
Heavy Metal Contamination is the excessive presence of metals like lead, cadmium, chromium, mercury, arsenic, etc., in the water.
1. Find out the Water Source at home.
2. Choose the Water Purification Technology
As part of the water purification process, multiple filtration systems ensure that you get the safest, clean, and healthy drinking water. You must ensure that the water purifier you choose will have at least one pre-purification, one purification, and one post-treatment technology.
Pre-purification (An Overview of different water filters)
There are 2 pre-purification systems that ensure the removal of impurities from water.
Sediment filter/Pre-filter: An external filter that removes suspended solids like dirt, sand, rust, etc.
Pre-carbon filter: By getting rid of organic chemicals, VOCs, pesticides, herbicides, chlorine and its by products, this filter removes odour and improves the water’s taste.
Having both these filtration technologies would be recommended for the best pre-purification outcome.
Once the visible impurities are removed, the primary filters ensure that pure water is attained without unnatural influence.
a) RO Purifier Technology:
Reverse Osmosis Technology pushes water through a membrane, assuring that only pure water passes through the other side, eliminating any harmful substances. This technology is recommended for water sources of all TDS levels. A.O. Smith RO Water Purifiers ensure 100% pure water through its patented Side Stream RO
b) Ordinary RO + UV
While each technology has its advantages, a combination of both has its issues in ordinary water purifiers, as some of the water goes through UV while bypassing the RO membrane first.
Ordinary RO UV water purifiers bypass some water directly to UV without passing through the RO membrane.
Ordinary RO UV water purifier gives way to harmful substances like TDS, lead, arsenic, fluoride, pesticides, and other chemicals, which may lead to severe health effects.
A.O. Smith RO Water Purifiers ensure 100% water passes through its patented Side Stream RO technology, preventing such issues.
c) UV Purifier Technology
Using electromagnetic radiation, UV rays deactivate any viruses, bacteria, or other microorganisms found in the water by altering the DNA of the cells. This technology is highly effective for water sources with TDS levels below 200.
a). UV – UV lamp filter is also used as a secondary source of purification and RO. It uses the same mechanism as described above.
b). UF – Ultrafiltration can remove most contaminants, excluding viruses, chemical reductions, and phosphates.
c). MF – A Micro Filtration Membrane with bigger pores than UF can remove most contaminants, excluding viruses, colloids, chemical reductions, and phosphates.
SCMT
Silver Charged Membrane Technology (SCMT) is a membrane charged with silver particles. A.O. Smith patented its design. SCMT technology is more effective than UV, UF, and MF as it removes bacteria, viruses, cysts, colloids, particulates, and endotoxins.
1. Post Treatment technology (overview of different water filters) serving as the final filtration stage ensures that the water is in its finest form for consumption.
2. Post-carbon filter, like the Pre-carbon filter, the same process can be repeated on the water to remove odour and improve the taste.
3. Mineral filter adds essential minerals like calcium and magnesium to ensure that the water has a balanced pH.
4. In-tank protection by including a UV LED lamp inside the tank, the purified water stored remains fresh and clean, preventing microorganisms from growing.
3. Choose Water Purifier Storage Capacity
Storage capacity is mostly dependent on the number of people that require it in a household.
The water storage tank in most purifiers is generally made of food-grade plastic. A.O. Smith water purifiers are made using 100% food-grade plastic, safe for drinking water storage.
1. Decide Placement of Water Purifier
Deciding where your water purifier sits will depend on the size and aesthetics of your kitchen. A.O. Smith Water Purifiers provide 3 convenient options: Wall Mount, Table Top, and Under-the-Counter.
These options speak for themselves. However, do note that Under-the-Counter water purifiers come with an elegant faucet on the sink that dispenses water above.
2. Our Value-added features
You can always expect extra benefits with A.O. Smith Water Purifiers, as they can include the following value-added features:
i) Dispense Hot Water at Press of Button
Ranging from warm to hot, 45 to 80 degrees specifically, the Z1, Z8, Z9, and ProPlanet P7 & P6 models by A.O. Smith provides mineralized hot water at the press of a button that is heated within a steel tank. Regularly drinking hot water regularly leads to health benefits like relief from nasal congestion and sore throat relief, enhanced blood circulation, smooth digestion, and body detoxification.
ii) Water Saving
We share a desire to promote sustainability and an eco-friendly lifestyle. As part of RO purification leads to the rejection of impure water, the pure water that passes through is lesser than expected.
Water recovery means the percentage of water that passes through the RO membrane and is recovered as pure water, a percentage of the water saved.
Most water purifiers in the market recover only one glass of pure water for every 4 glasses of input. So, the recovery is 25%.
Some of our water purifiers include ART Max (Advanced Recovery Technology), which saves more than 9000L of water annually. The new ProPlanet series is India’s First 5-star rated water purifier series in terms of water savings and has a recovery of more than 60%.
iii) Night Assist mode
Serving as an aid in the dark, as well as elevating the purifier’s beauty, the Night Assist is a handy feature that is included in some A.O. Smith Water Purifiers for home.
iv) Register for Warranty
Most brands offer a 1-year warranty against any manufacturing defects but doesn’t cover any filters.
A.O. Smith’s 1-year comprehensive warranty covers any and all issues with the product, including covering RO membrane, all filters and electrical and functional parts.
So, what are you waiting for? Explore the A.O. Smith Water Purifier range and find the one that is ideal for you and your home.
