Practical Considerations Before Buying A Water Purifier For Your Home

Currently, there are multiple water purifiers available in the market. All water purifiers have their own USPs and all claim to give the best water quality. However, what you need to keep in mind is that all water purifiers come with different technical specifications and have certain basic requirements.

Knowing which one will work for you, depends on factors like water pressure, water quality, and space available and if you are unsure which one you should go for, then take a look at this guide on how to choose a water purifier to select the best water purifier for home use.

Now, before we delve deeper into which is the best water purifier for home use, let us first understand what are the most common water purification techniques.

1. Most Common Water Purification Techniques

There are different types of water purification techniques, however, here are some of the most commonly used water purification methods that have proven their suitability for home use.

  • Activated Carbon Filters

Activated Carbon filters work on the adsorption method. When water passes through a carbon filter, activated carbon adsorbs harmful molecules that are present in water. An activated carbon filter is used as a complementary filter with other water purification techniques like UV purification and RO purification.

  •  Ultraviolet Purifier

UV purification is the best option to get rid of bacteria and viruses without removing essential minerals that are available in your drinking water. UV purification is the most eco-friendly way to purify your water because it does not add any chemicals to your water and it does not waste your water Also, UV technology is a popular choice for industrial water purifiers.

  •  Reverse Osmosis Purifier:

The RO technology is mostly used in home and commercial water purifiers. RO purifiers filter out harmful pollutants through their semi-permeable membrane. RO-filtered water may taste flat because reverse osmosis removes some essential minerals from your water. It is needed if the TDS level in your water is above 500 ppm.

2. What is TDS?

TDS is the Total Dissolved Solids present in your water. TDS is composed of inorganic salts & small amounts of organic substances which are dissolved in water. Safe levels of TDS for the human body are under 500 PPM. Generally, groundwater (water for bore wells, and tube wells) has high TDS unlike surface waters (water from rivers, lakes, reservoirs, and ponds).

National Green Tribunal’s (NGT) Take on RO Purifiers

RO water purifiers for home have become the preferred water purifier in households today, thanks to aggressive advertising campaigns, and varying levels of TDS in water throughout the country. In response to a petition filed by an NGO called “FRIENDS” in Delhi, the NGT has ruled that in light of the wastage of water by RO technology and adverse health effects of drinking water with a low TDS devoid of certain essential minerals, RO water purifiers be banned in areas where the TDS of water is below 500 mg/liter. Hence, the National Green Tribunal has directed the Ministry of Environment and Forests (MoEF) to issue a notification banning RO purifiers where total dissolved solids (TDS) in water are below 500 milligrams per liter. The matter is currently sub judice and no final legislation has yet been passed to this effect.

At Alfaa, we have always maintained that water with TDS of less than 500 mg/liter be further tested for dissolved pollutants before a RO water purifier is used, and only if it is warranted should RO be used for water with TDS under 500 mg/liter. Instead of low TDS water, UV purifiers are more environmentally friendly, while ensuring the purity and safety of drinking water, without any wastage of water.

3. How to Select the Best Water Purifier for Home Use?

While you may come across many water purifiers online, the below-mentioned parameters will help you decide which one is the best water purifier for home use.

Different types of water purifiers – which one is suitable for your water?

Is your water surface water (from rivers and lakes) that has been supplied by the municipality or is it groundwater (from borewells, supplied by tankers) or a mixture of both?

Suppose it is surface water, supplied by the municipal corporation. In that case, chances are that the TDS (dissolved impurities) are low and you need to only protect yourself from microbiological impurities like bacteria and viruses. However, if your water is groundwater supplied by tankers, there may be a higher level of dissolved impurities, altering the taste of the water, and at higher levels may affect your long-term health.

As a thumb rule, if you get groundwater, check the TDS with a simple TDS meter. If your TDS is above 500 ppm, then choosing an RO water purifier may be beneficial. If the TDS is lower than 500 ppm, then a well-designed UV purifier will be effective in purifying the water. If you get a mixture of both – ground and surface water then an “intelligent” purifier with sensing purification technology will be effective.

Most companies selling water purifiers do this simple TDS test. It is important to note that using a RO water purifier where TDS levels are low, say under 200 ppm, may be detrimental to your health in the long run, as the water is stripped of essential minerals and salts.

There is also substantial water wastage in a RO water purifier (up to 80%), so unnecessary usage is a waste of a valuable resource.

PureSense – The Best ro+uv+uf+tds Water Purifier

Take a look at Alfaa’s Puresense – Universal water purifier that treats any varying water source such as Bore well / Municipal or Tanker water by automatically selecting the required technology: either UF / UV or RO, based on the indicated TDS setting (Total Dissolved Solids) defined by the customer.

Water Pressure – what is the required water pressure for a water purifier?

Checking for water pressure is important before you buy a water purifier online. Water purifiers normally need a pressure of between 5-40 PSI (pounds per square inch) for them to work effectively.

An easy way to calculate the pressure in your tap is to see how many floors you are from the terrace from where water is distributed by gravity.

So if you are in a 10-story building and you live on the 8th floor, then your water pressure is likely to be 10PSI, because every 10 feet from the top is equivalent to 5 PSI. If you live on the 1st floor, then the pressure in your tap will be around 45 PSI. If that’s the case, then a pressure-reducing valve will be required along with the water purifier.

For homes with very low pressure, a booster pump will help or alternately a UV purifier that works on loft tank pressure can be opted for.

Take a look at the  Alfaa UV’s Ewater purifier that works on loft tank pressure, and makes it an attractive option in homes where the pressure is low.

 Location of Water Purifier

Locating the water purifier near a source of water and an electrical point with earthing is important. Ideally, the distance between the purifier and the water / electrical point should be within 3 feet.

Also, keep the purifier away from direct heat or sunlight. If space is an issue, or if you would like to keep your counter space empty, opt for a wall-mounted purifier. In most cases, apartments today provide a special water outlet near the sink in the kitchen to which the purifier can be easily connected.

Here is Alfaa UV’s Dewdrop RO Water Purifier which is designed for both – Countertop as well as Wall mount use

Power supply (Electricity)

This is another important parameter that you need to keep in mind when deciding which water purifier to buy. If you have frequent electric outages in your area, then it is best that you opt for a water purifier with storage. These non-electric storage water purifiers work on gravity rather than electricity; thus, it is a good option to consider if you experience an erratic power supply in your neighborhood.

Budget

Before you look for water purifiers online, it is important that you have a budget in mind. This will help you select a water purifier that encompasses all the parameters – water type, TDS levels, etc. Plus, if your budget is low then you can opt for alternatives that would do a particular job well. If you can’t find a water purifier within your budget, then fret not and just simply contact us and we’ll suggest you the best water purifier and filter for home use.

Service

It is important to understand that fundamentally a water purifier, whether UV or RO, needs regular servicing and replacement of critical components. Service & maintenance needs may differ depending on the water quality, which means the poorer the water quality, the more frequent the service required.

So check the service availability in your area and the credentials of the service provider, before you buy a RO water purifier or a UV water purifier for home use.

4. Additional Benefits with Special Features

To ensure that you have purchased the best water purifier for home use, look for the following features when searching for a water purifier online.

  • 5 Stage purity process
  • Stainless steel purification chamber
  • Energy saver standby mode
  • Dual process filtration for high performance
  • Inbuilt kitchen timer
  • Futuristic PureSense Controller to continuously scan purity
