It the beginning, we have to know details about purification system to save our lives. We should be confirmed that our drinking water is hundred percent pure. The followings are cost-effective water purifiers have been manufactured with purity in mind. And that is why this is the best water purifier in the market.

In drinking water, lots of minerals are found that we import into our body. However, the excess amount of these elements will create many diseases in our body. An excellent purifier removes these excess salt, suspended particles, and microbes from water. At the same time, the water adds essential vitamins and minerals to the water.

The function of water purifier and water filter are the same to some extent. At first, it sucks up contaminated water, removes impurities and makes water clean and fresh. There are some differences between these two.

The function of a purifier is to eliminate viruses. The filter cannot remove bacteria. Some purifiers use electrostatic charges to kill bacteria or remove chemicals.

Purification of Water

Ultimate Best water purifier Buying Guide

Water purification means to remove contaminants from raw water resource. The goal of water purification is to make water fit for a particular purpose.

The primary objective is to make water fit for drinking. There are other uses to purify water such as pharmacology, medical, industrial and chemical applications.

Different methods can do it. Such as filtrationreverse osmosiswater softening, molecular stripping. And treatments along with ultraviolet light, carbon treatment, and deionization.

Water purification can remove many contaminants from water. Such as suspended particles of natural material and particulate sand. Also, parasites like Giardia and Cryptosporidium, algae, fungi, bacteria and viruses. And toxic chemicals like lead, chromium, and copper. Some minerals like silica, magnesium, calcium also removes from the water.

Some purifiers use elective for the purification process. Such as removing smell (hydrogen sulfide remediation, color (from iron encapsulation), taste (mineral extraction).

Government always speaks about the standard of pure drinking water. The standard is maintained by the minimum and maximum level of contaminants.

The standard of water needs some purifier like chlorine, furthermore ozone mixed in water. Then water leaves the water treatment plant (WTP). That lessens the risk of re-pollution when water distributes to the distribution process.

As a drinking water, people consider groundwater is safer than the surface water. Like water from rivers, lakes, and ponds. The water is pre-filtered by the aquifer from where the water is collected.

The large water body of the world, aquifers are regenerated. As the part of the hydrologic cycle. In the waterless region, the aquifer is somewhat limited output. It will take thousands of years to recharge.

As this is a water source, more monitoring is a must by the WTP operators.

If the surface water is much, the subsurface formation will not work properly. The underground water is more than the visible surface water.

Surface water is the main source of drinking water. In the situation where there is a scarcity of groundwater or reduced amount of water.

As this is a water source, more monitoring is a must to maintain the presence of contaminants by the WTP operators.

Advancement of purification methods

The traditional water treatment system is to add chlorine with water. Hydrochloric acid comes from chlorine, reacts with microorganisms and fights with them to clean water. The system has adverse effects on health.

The system kills some protozoa which are essential for the body. So people now like to move to the upgrade system to get pure water.

There are five different types of water purifier in the market. The common thing that we find in all water purifier is that all the purifier has a water filter.

Active Carbon filter

best water purifier for lives

This filter is used to remove soluble gases from the water. Like, carbon monoxide, chlorine, ammonia, and nitrogen. Some organic materials such as dead algae, dead things of water, leaves.

The leaky nature of carbon aids to absorb chlorine and some pollutants like pesticides. Some household carbon filter appears with a lining for stimulated silver that’s the bacteria-killing power.

Bio-sand clean

The biofilter’s made of concrete and plastic which contains the stages of sands or gravel. The task of this sand is to remove pathogens (and removes solids from polluted water. Pathogens’ a microorganism cause of our sickness.

Water is poured on the top of the filter and then reserved in the storage pot. Bacteria and another microorganism grow on the top layer of sands are called biolayer.

The bio-layer eats away pathogens and improves the quality of water. The bio-layer removes particles and pathogens then purify 12 to 18 liters in each batch.

Reverse Osmosis Filters

Reverse Osmosis’s a multi-stage filtration system of water by adjoining active carbon and particle filtration. Here tap water will pass through a membrane which has tiny pores.

The system weeds out minerals and microorganism from the water. The impurities are passed through an outlet pipe.

The RO system’s water is delightful. But we cannot say that the water is hundred percent safe. As there are some holes in the membrane, some bacteria will get through filters.

The RO system’s suggested to the place where there are many minerals dissolved in water. The demerit of RO system’s that sometimes filter drains out some essential minerals also. So it needs a continuous water delivery to function well. Can add to the water tap.

Ultra Violet (UV) filters

The ray of UV is fallen in water to make it bacteria-free and other microbes. That attack DNA cells. The power of removing pesticides is 99%. The device is the best one for removing pathogens.

But it’s not very efficient to remove suspended particles like smell, color, taste, and chemicals. The purifying power of the device is 2000 liters per day.

Ion exchange resins filters

Here water runs into resins which absorb minerals and makes the water soft. The filters make water soften by sucking salt from water and demineralize water.

Merits of the best water purifier


The ion alternation method penetrates water through spherical resin materials. One ion is exchanged for other ions connected to the beads. The general ion exchange methods are deionization and softening.

Softness is the way to reduce water hardness from water before Reverse Osmosis processing. The softeners hold beads which exchange two sodium ions for calcium or magnesium ions.

Deionization beads alternation of hydrogen ions for actions or hydroxyl ions for anions. The cation replaces resins, comes from styrene as well as divinylbenzene having sulfonic acids collection.

They replace hydrogen ions for cations they faced with (e.g., Na+, Ca++, Al+++).

Similarly, anion replaces resins, consist of styrene having containing quaternary ammonium groups. Replace a hydroxyl ion for anions (e.g., Cl-) replace from fresh water.

The resins keep in a separate bedroom with separate unit for cation or anion exchange beds. Or sometimes stay in mixed bed having both types of resins. If hydrogen exchanges, the resin must be regenerated.

The regeneration turns around the purification method. It replaces the contaminants add to the DI resins along with hydrogen or hydroxyl ions.

For the water purification system, deionization is an important issue. The DI removes ions well but do not remove most organics or microorganisms.

The organisms can remain with resins. It offers a culture media for the quick growth of bacteria, and for generating pyrogen. The merits and demerits are discussed below.

Reverse Osmosis 

Reverse osmosis (RO) is the best way to remove 95% to 99% contaminants from water. The aperture structure of the RO membrane is somewhat tighter than UF membranes. The RO can avoid particles, organics, and bacteria less than 300 Daltons molecular weight.

Reverse Osmosis

Natural osmosis happens with the help of a semi-porous membrane while extracting two different concentrations. Osmotic pressure leads water to the membrane.

The water adulterates determined solution.

The final result is equilibrium. Hydraulic pressure is given to the water purification process, to counteract the osmosis pressure. Then fresh water comes and reserved to the membrane.

As RO membranes are preventive, they offer slow rates. Storage water reserves a significant amount with the passage of time. RO has an ionic exclusion method. The semi-permeable RO membrane permits the only solvent.

There will remain no salts in the semi-permeable membrane for phenomenon action. If the charge becomes high, the amount of rejection will great.

So, the membrane removes nearly about 99 percent ionized polyvalent ions. Also, about 95% of weakly ionized monovalent ions such as sodium. Various feed water needs different types of RO membranes.

For a different kind of water separate RO membrane needs. RO is the best water purifying system to purify tap water.

If the system’s applied correctly, the feed water will be more fresh and cleaned. For reagent grade water, RO is the optimum pretreatment polishing methods.

Ultraviolet conduct

Recent UV is used to produce different lamp. That creates both 185nm and 254nm UV light. The combination of water lengths is a must for photo-oxidation of natural compounds. By applying this lamp, Total Organic Carbon (TOC) purify water can be reached to 5ppb.

Frequently Asked Questions (FAQs) On Best Water Purifier Reviews

Question: What is the reason to have water purifier at my house?

Answer: Every family feels the need for pure drinking water for drinking, cooking, and bathing. It does not matter at all where you are living in the city; chlorine is added to water treatment plant to remove bacteria and algae.

Other chemicals are added for accomplishing other purposes. How much chemicals you will eliminate from the water to avoid the long-term effect on a body.

Millions of people faced premature death for the presence of Chlorine with water. Chlorine combines with other compounds and makes harmful toxins.

For example, we see the presence of THM’s and MX’s in the chlorinated water supply. THM’s is taken from chlorine with humic acids extracted from destroyed subjective matter.

Question: What do you know about water purification?

Answer: Water purification means to make water free from any impurities. Such as microorganism and contaminants. Water purification is not a single process. There are lots of steps to overcome to make water purified.

The steps depend on the impurities present in water. Different kinds of water need various types of actions. 

Question: What about the bottled water?

Answer: Bottle water is not pure at all. There is no testing of bacteria in the bottle. How do you maintain the instruments of water purifier? Is there clean water in the bottle at all?

Most of the bottled water is spring water and is not safe. It does not run through a filter at all. Some city water is filtered to remove Chlorine from water and intact in the bottle.

Fluoride and other chemicals remain in the bottled water. How long will continue the stored water? Apparently, bacteria will live in it.

The price of the bottled water is much. So it is expensive. Most of the bottled water contains BPA, a poisonous chemical which leaches into the water.

Some claim that the water of the bottle is BPA free. Instead, the water has BPS, which is also toxic. All the plastics have polymers which leach into the water.

Set up a water purifier in your kitchen, or at your home or your bathroom. That’s the best way to get pure water.

So why do you need not a water purifier for your family? You can get and fresh water at home if you use a water purifier. 

Question: What kind of water treatment can I buy?

Answer: At first fix up what you want to remove from water only certain contaminants. You can do it by an analyzing process. Then try to find what type of system you need to purify your water.

There are lots of resources from where you can buy your desired device. Keep in mind that overall the quality of water in the United States is right. So do not buy a product via scare or alarm tactics.

There are many water treatments are sold in the market. Try to find the best one for you. If you think, you can check it before buying. 

Question:  From where can I purchase the water treatment method?

Answer: You can buy the water treatment equipment from many reliable places. Some of the places are internet sales sites, home improvement outlets, and water conditioning companies.

Question: Does water treatment elements need any service or parts?

Answer: Yes, all the water treatment needs service after sometimes. You need to replace the filter, or sometimes you need to change membranes. You can take help from the manufacturers’ instruction and maintenance guide. 

Question: My water contains dirt in it. The water has color also. How can I remove color and make water clean?

Answer: If water is from well and the color is rust, then the reason is iron. If water is black, then there is sulphur in the water like manganese or rotten eggs.

You can make water fresh only by changing ion of water. If the water is filthy, be sure your water contains colloidal clay.

If you see mud problem, you can keep water in a glass for sixty minutes. After that, the clay will be visible on the nadir of the glass. If you see such problem, you can use coagulation filter.
