Why TDS is so important?

TDS is something that we hear a lot about when we are planning to buy a water purifier. Water can have a lot of salts and impurities in it. While we cannot taste or smell these impurities most times, they can be harmful to the body. TDS is a measurement that tells us how many impurities are in the water combined. TDS mainly measures heavy metals including mercury, lead, and arsenic, and dissolved salts. These impurities are deadly because our body cannot remove them, so they build up in the organs and blood.

If the system does not fit your faucet, you can order the new adapters from the PUR website. These adapters can fix the major problem of leaks that older models have with the water filter systems.

You will need to replace the filter after several months of continued use. It is recommended that you replace the system once a year. Luckily, this system is simple to install.

There are easy to read instructions and it comes with a variety of adapters. Within a few minutes, you can have the water filter system installed. The system is made from metal, so there is no need to worry about breaking it. This means you can screw the adapter on as tight as possible. Metal also is less likely to leak or break from regular use.

This is a great filter for the price. There is no longer any white particles in my water, which is a huge plus. I have owned this water filter for a couple of months, and it still works great. Installing it only takes a few minutes. The most common adapter size is made from steel, instead of plastic. I have not experienced any leaks. The only downside is that there is now limited space in my sink.

How to check the TDS levels of water

There are TDS meters on the market that you can use to measure the TDS levels. Water purifiers will come with rankings on the side, which will help you figure out what is the best option is for your home.

Level of TDS parts per million (ppm) Rating
Between 50 – 150 Excellent
150 – 250 Good
250 – 300 Fair
300 – 500 Poor
Above 1,200 Unacceptable

Different types of Water Purification methods and technology used in water purifier

There are three main types of water purifications that are used in most water purifiers that are on the market today.

RO (Reverse Osmosis) Purifiers: RO or Reverse Osmosis Purifiers are the most effective options on the market. This is because they can remove all dissolved impurities and salts from the water. An RO water purifier uses Reverse Osmosis which passes water through a semi-permeable membrane that removes the water’s impurities. The process does require electricity to work. The pores in the membrane are small enough to only the water molecule through and stop the large molecules of the impurities. If the water in your area has high levels of TDS, then this is the best option for your home.

UV (Ultra Violet) Purifiers: This type of water purifier uses a UV or ultraviolet filter that kills many types of bacteria, germs, viruses and other microbes. This is a very effective process of killing microorganisms. However, it may not remove dissolved impurities from the water. This type of water purifier is best used in areas where there are not high TDS levels, while there are still microorganisms in the water. These systems will need electricity as they use a UV lamp to kill all the microbes.

UF (Ultrafiltration) Purifiers: This is another type of filter that will remove bacteria and germs from the water. This system uses an ultrafiltration membrane that purifies the water. This membrane has pores that will only allow water through and catches the germs and bacteria. The pore size of a UF membrane is not as small as RO, so UF filters can allow impurities through. The UF process does not require any power, but they can leave heavy metals and salts in the water.


If you are living in a house where storage space is limited, you should make sure that you pick a unit that fits the space and provides enough pure and safe water. Many water purifiers will have built-in storage capacity. Seven to eight liters of storage is good for most households. Larger units are available if you have a larger family or have high water needs.

Maintenance and after-sales Service

Before buying any water purifier for your home or business, it is important that you check its maintenance cost. Many times, maintenance costs will depend on the unit. When you buy a water purifier, the maintenance costs should not be as high for the first 3 to 4 mounts. After some use, maintenance costs will start adding up. If you are worried about maintenance costs, you can call the company, and check online reviews. Online reviews can help you avoid companies that have bad customer service and high maintenance costs. You should always buy from trusted water purifier brand that has great customer support.

Purification of Water

Water purification is defined as the removal of contaminants from a raw water resource. The main goal of water purification is to make the water fit for a general purpose. Most times, this is for drinking. There are other uses for purifying water, which include industrial, medical, pharmacology, and chemical uses.

There are different methods that can be used to purify water. These methods include water softening, molecular, reverse osmosis, and using filters. There are also other methods such as deionization, carbon treatment, and ultraviolet light.

Water purification is able to remove many contaminants from water, which can include suspended particles like grains of sand and tiny pieces of rock. Viruses, bacteria, fungi, algae, and parasites are also removed. Toxic chemicals include copper, chromium, and lead can be removed with a water purifier. Minerals such as calcium, silica, and magnesium can also be removed from the water.

There are some water purifiers that use electricity in their purification process. Many water purifiers that can remove taste, color, and smell from the water because it removes the cause of these issues.

Many governments speak regularly about the standard of safe and pure drinking water. Most governments have a minimum and maximum level of contaminants that safe water can have. These water standards are reached by many methods. Most places use chlorine and ozone to lower the TDC and germs in the water. The issue is that once the water leaves the water treatment plant, the contaminants could re-enter the water before reaching your home. This is why many people use a water purifier in their home.

There are five main types of water purifiers that are available on the market. The common thing that most water purifiers have is a water filter in them.

Active Carbon filter

Active carbon filters are used to remove soluble gases from water, which can include nitrogen, ammonia, chlorine, and carbon monoxide. These filters can also remove organic materials like leaves and algae from the water. The leaky nature of carbon aids the absorption of chlorine and many pollutants like pesticides. There are some active carbon filters that have a simulated silver lining, which kills bacteria.

Bio-sand clean

These bio-filters are made using a mixture of plastic and concrete which contain different stages of gravel and sands. The sands are used to remove pathogens and solids from polluted water. Pathogens are the microorganisms that cause us to become ill. This filter will have the water poured on top and there is storage pot under it, so gravity forces the water through the filter. Bacteria and microorganism can grow on the top layer of sand, which is called the biolayer. This bio-layer is important because it eats the pathogens, and improves the water’s quality overall. This layer can remove pathogens and particles from 12 to 18 liters of water.

Reverse Osmosis Filters

Reverse Osmosis filters are multi-staged filtration systems that use both particle and carbon filtration. The tap’s water passes through the membrane that has tiny pores. This water filter system removes microorganisms and minerals from the water. The impurities are removed from the system by an outlet pipe. These RO systems are great, but the water from these systems are not a 100 percent safe. There are holes in the membrane, so some bacteria can get through.

The RO systems are suggested for areas where there are many minerals in the water. The main downside of RO systems is that they can filter out some essential minerals. They can also lead to large water bills because they need continuous water flow to work well.

Ultra Violet (UV) filters

Ultra Violet or UV filters use UV rays to kill bacteria and microbes that could be living in the water. UV rays attack the DNA inside the bacteria and microbes. UV filters have been found to remove up to 99% of pesticides, bacteria, and germs in water, so this is the best option for removing pathogens. However, these filters are not efficient at removing suspended particles that could cause odd taste, colors, and smells. These filters can process up to 2000 liters per day.

Ion exchange resins filters

These filters use resins that absorb minerals and makes the water softer. These filters demineralize the water.


Drinking pure water is one of the most important things for our health.

If you are drinking and using water that is coming from a municipal water system, you are most likely ingesting high amounts of chlorine, and probably fluoride. These two chemicals can have huge effects on your health.

You most likely do not have the room for a large or bulky water filter or one that takes up most of the space under your sink. Before buying a water filter system, you should make sure that it will fit under your sink.

The best part about most water filter systems is that they can be installed without the help of a professional. If you want to install the filter by yourself, look for a system that comes with its own installation kit and has filters that are easy to change. Many filters are able to be twisted on and off, so it only takes a few minutes to change the filter.

No matter the system that you pick, the filter in the system will need to be replaced. This is a huge part of the maintenance cost. The lifespan of the filter will depend on the system and the water that you are putting into the system. Some filters will last less than three months, while others will last over a year. It is recommended that you check and change your filters every 6 months. The best water purifier systems on the market have a light or sound that will tell you when you need to replace the filter

Installing a water filter is the easiest way to ensure that your water safe. These systems can also improve the color, smell, and taste of water. A drinking water filter system is a very simple thing that you can do to have a lasting effect on your overall health.
