How to decide on which type of water purifier is needed for the home?
All of us do know some general benefits of having a water purifier in our home as every human being requires access to clean and safe drinking water, so here is a water purifier buying guide for you.
Many parts of India are experiencing water scarcity, forcing residents to rely on groundwater or water delivered by tankers. Due to the presence of contaminants such as pesticides, heavy metals, bacteria, cysts, and excessive TDS (Total Dissolved Solids), the quality of water from such sources may be poor. It's no surprise that more people are turning to water purifiers to clean their drinking water.
If you want to purchase a water filter for home, the sheer quantity of brands and types available on the market can be overwhelming. Because there are so many different types of water purifiers, you'll need to know a few things before you can start narrowing down your options. So we have summed up an easy water purifier buying guide to help you pick the best purifier for your home.
#1 Water purifier buying guide - What to keep in mind when choosing a water purifier?
Before deciding on a water purifier, you must first determine the source and quality of the available water such as its hardness, salinity, and TDS.
Now let's check out what is TDS in water, and how much is deemed safe to drink?
TDS stands for total dissolved solids, which refers to the inorganic salts and small amounts of organic matter that are present in the water. Calcium, sodium, magnesium, and potassium cations and hydrogen carbonate, carbonate, sulphate, nitrate anions, and chloride are the most common elements in TDS. TDS is commonly measured in milligrammes per litre (mg/L) or parts per million (ppm) (parts per million). You can either get your water tested in a lab or use a TDS meter, which can be purchased locally or online.
TDS levels below 200 ppm are generally considered to be extremely good for drinking. TDS levels in groundwater typically range from 500 to 3000 parts per million, necessitating the use of a RO water purifier to clean it. This is one of the most important points in the water purifier buying guide that you must remember.
#2 Water purifier buying guide - What are the types of water purifiers?
RO (Reverse Osmosis), UF (Ultrafiltration), and UV (Ultraviolet) are three different types of water purifiers. Some water purifiers combine multiple technologies, such as RO and UV, to purify water. You must select the sort of water purifier that best meets your needs based on the TDS level. You may simply require a UF or UV water filter, or a mix of both, for low TDS water (200 ppm or less).
- RO Water Purifier
In a RO (Reverse Osmosis) water purifier, a pump forces high-pressure water through a semipermeable membrane with pores as small as 0.0001 microns. Dissolved particles and contaminants are left behind as water molecules pass through to the other side. A separate outlet, known as a reject line, is used to discharge some of the input water and contaminants.
Other filtration elements, in addition to RO membranes, are used to improve the filtration process and extend the life of the real RO membrane. These filters are referred to as 'Stages.' The filtration process in a RO machine begins with the first filter, known as a Sediment Filter. The Sediment Filter purifies the water by removing all the suspended impurities. The Activated Carbon Block filter is the second filter, and it removes chlorine, bad odors, and adsorbs pigments. Water is pumped through a post-carbon filter after filtration by the RO membrane to improve the taste and appearance of the drinking water.
The most effective water purification method is reverse osmosis (RO), but it requires electricity and may waste some water. If you currently have water with a TDS level of 200 ppm or below, a RO water purifier may not be necessary. You can simply choose a UV water purifier.
Many water purifiers like Pureit RO water filters, however, offer purifiers with water recovering technology, which can subsequently recover 60% of water and can help you save up to 80 glasses per day.
- UV Water Purifier
UV water purifiers work by exposing bacteria and viruses to ultraviolet light, which helps in killing them. These types of water purifiers have a quick filtration process. They cannot, however, remove dissolved solids or chemicals from water.
- RO+UV Water Purifiers
High-end water purifiers combine both RO and UV technology to purify impure or tap water. First the water goes through the RO membrane, which removes undissolved as well as dissolved solids, and then through the UV chamber, which more efficiently neutralizes germs and viruses.
As more people are depending on groundwater supply, which has poor quality of water, many are opting for water purifiers for drinking clean water.
When buying a water purifier for home, there are few things which need to be considered like water quality, water pressure, budget, storage capacity, maintenance, etc.
There are a number of purifiers available in Indian market, such as RO (Reverse Osmosis), UV (Ultraviolet), UF (Ultrafiltration). etc to choose from.
A filter must be selected depending on the level of contamination. If the water has TDS level more that 500ppm an RO purifier or a combination of RO+UV+UF is highly recommended.
#3 Water purifier buying guide - Types of water Purfiers based on Technology
In addition to reducing the concentration of a variety of dissolved and particulate materials, water purification can also lower the concentration of suspended particles, parasites, bacteria, algae, viruses, and other fungal organisms.
There are various ways to purify water. When it comes to maintaining human health, water purification is of the utmost importance. The dangerous elements in the water can cause people to get a number of diseases that are transmitted through the water and can ultimately be fatal.
Let's look at the different types of water purifier:
a. RO Technology: RO membrane technology is used in the widely used water purification process known as reverse osmosis. It is used to purge the water of pollutants, bacteria, and dissolved salts.
Only water may flow through the semipermeable membrane; hazardous compounds, dissolved salts, and microorganisms that are floating in water are left behind. The taste of water is also made sweeter by a RO water filter, which is appropriate for hard water with a high TDS level.
b. UF Technology: The ultrafiltration method of purification likewise uses membrane technology, but it does so with a membrane that has larger pores. It cleans the water of all minute impurities. However, it can't get rid of dissolved salts and solids.
The UF purification method has a very low TDS and is suited for water that isn't overly hard.
c. UV Technology: It is possible to remove 99.99% of dangerous organisms from water using the ultra violet purification method, which uses ultraviolet light to eliminate germs, bacteria, cysts, and other unwanted species. It makes use of a tiny mercury lamp to produce short-wave UV radiation that cleans water and penetrates bacterial and viral cells, stopping them from reproducing and eventually killing them.
#4 Water purifier buying guide - How to Select the Best Water Purifier for Home Use?
While there are numerous water purifiers available online, the characteristics listed below in this water purifier buying guide will assist you in determining which is the finest water purifier for home usage.
Is the water (from rivers and lakes) supplied by the municipality, groundwater (from borewells, delivered by tankers), or a combination of the two?
If it's municipally supplied surface water, the TDS (dissolved impurities) are likely to be low, and you just need to worry about microbiological pollutants like bacteria and viruses. If your water is tanker-supplied groundwater, however, there may be a higher level of dissolved pollutants, altering the flavour of the water and, at higher levels, perhaps affecting your long-term health.
If you get groundwater, check the TDS with a simple TDS metre as a rule of thumb. If your TDS level is more than 500 ppm, a RO water purifier may be advantageous. A well-designed UV purifier will be successful in purifying the water if the TDS is less than 200 ppm.
A Pureit technician can help check the TDS levels of your water and recommend a water purifier on that basis.
A TDS test is essential to choose the right type of water purifier for your home. A Pureit technician can help check the TDS levels of your water and recommend a water purifier based on the type of water and TDS levels.
#5 - Water purifier buying guide - Key Takeaways
While it may appear that purchasing a water purifier is as straightforward as going to an e-commerce platform, picking a favourite brand, and putting an order, the reality is that there are numerous variables to consider before choosing the perfect water purifier for your home.
These elements also differ by geography, so your preference may change as a result. With that in mind, here are eight considerations you should make before purchasing a water filter for your home.
- Water quality
This is the most critical factor to consider in any water purifier buying guide covered for you when you decide to choose a water filter for your home. Hard water, or water with a high amount of TDS (Total Dissolved Solids), is likely to be provided to your home. TDS is a measurement of a liquid's dissolved combined content of all organic and inorganic components. Calcium, potassium, magnesium, sodium, chlorides, bicarbonates, and sulphates are among the inorganic salts present.
Contamination is the second point to consider in the water purifier buying guide. The presence of heavy metals such as magnesium, lead, arsenic, copper, and iron is referred to as pollution. These heavy metals can be harmful in excessive doses. The presence of heavy metals in the water is attributed to industrial waste.
While RO can remove inorganic compounds and even heavy metals, germs and other microbes will require a specialized filter. A UV filter in a water purifier can remove harmful bacteria and viruses in the water. To do so, they employ a UV lamp, and you may also look for a UV filter with an ultra-filter to eliminate bacteria suspended in the air. When the water supply is free of total dissolved solids, this works well. Check out boiled water vs filtered water difference to understand this point further.
- Storage Capacity
Another aspect to consider is your family's normal daily water use and we have listed it in our water purifier buying guide for you. The first option you must consider is whether you require a purifier solely for drinking or for the entire house. After you've determined the requirement, you'll need to calculate out how much you'll need. If you use a lot of water on a regular basis, you will need a water purifier that has a large storage capacity. Storage capacities varies with each type of Pureit water purifier and it is one of the key factors while choosing a water filter.
It is essential to set a budget once you have determined your usage and the type of filtration technology you want. A water purifier isn't like a smartphone that you replace every year or two years. It is a long-term investment that will necessitate a financial commitment. As a result, we advise choosing a reputable brand like Pureit. You will need to invest at least about Rs 10,000-Rs12,000 on a water purifier, depending on the dependability and type of filter you choose.
- Maintenance cost
A water purifier is considered as a household appliance, which means it will need maintenance. The filter must be changed, and the complete system must be serviced as part of the maintenance. As a result, you must include in the cost of maintaining the item every three or four months. In addition, you'll have to replace the filter once a year. You can opt for Pureit water purifiers which have low maintenance cost such as Copper UV, Classic UV, Classic G2 RO+UV etc.
Its a known fact that drinking water must be clean and odourless in order to have a healthy, disease free lifestyle. You can shop for copper water filter online and choose from multiple purifiers from Pureit which suits your home and family. We hope this water purifier buying guide helps you in your quest to get the best purifier for your home.
