1. Using a Water Purifier Product

Water Purifier *BESTSELLERS*:

The simplest way to purify water easily is with a reliable water purifier product. Today, companies offer tons of products for your home, even whole house water purification systems. This equipment assures bottled water quality at your faucet, ON DEMAND.

So, what is the best water purifier available online? Check out a few of these bestsellers below:

2. Boiling Water

Boiling is the simplest tactic among water purification methods to cleanse water that is unsafe because of micro-organism contamination such as viruses, parasites, or bacteria. The notion in this style of sanitation is that the micro-organism is eliminated by pushing the bacterium or virus past its heat range.


  • Get access to some household cooking facilities with fire
  • Or when such facilities are not available, some type of outdoor/camping cooking equipment can also work
  • After preparing the materials, bring the water to a rolling boil for 3-5 minutes, and to be extra safe, let the water boil rapidly for one minute, especially at higher altitudes since water boils at a lower temperature
  • Let the water cool before drinking

One of the prevalent advantages here is that you are not adding any chemical to your water; however, boiling will not remove metals or harmful chemicals. So, be wary if the contaminants are metals, nitrates, pesticides, solvents and the like.

3. Reverse Osmosis

RO water purifier products use a process wherein inorganic solids such as salts are removed from a solution by applying a pressure in excess of the osmotic pressure. This is universally known for its use in drinking water purification from seawater.

If you are in the market for a great way to purify your own water at home,  please check out our list of the best reverse osmosis water filters available online.

4. Water Chlorination

This is an emergency water purification where water can be made safe for drinking by remedying with liquid household chlorine bleach. Household bleach is normally between 5% and 6% chlorine, and this is a heavy-duty oxidant that swiftly kills many harmful micro-organisms.

By using this method, keep in mind that regular household bleaches have an expiration date and you should only use those that do not contain perfumes, dyes, and other additives.


  • 1
    Place the water in a clean container and add the amount of bleach corresponding to the table below:



16 drops bleach

Per gallon or four-liter container of water

8 drops bleach

Per two-quart, two-liter or half gallon container of water

4 drops bleach

Per quart or liter container of water

  • 2
    Mix carefully and permit to stand for at least 30 minutes or at least an hour if the water is chalky before using.
  • 3
    Enjoy a rather strange-tasting, yet purified, delight. Needless to say, drawbacks to water chlorination include aesthetic apprehensions such as taste and odor.

5. Ozonation

Ozonation is used mainly used by European countries to produce purified water. This method uses ozone, a pale blue gas with a peculiarly bitter smell, as a disinfectant. This is created on-site and added to the water by bubble contact in order to break down a wide variety of nonliving, biological and microbiological problems and taste and odor problems.

Nevertheless, this system has a higher equipment and operational cost, and probable fire hazards and toxicity concerns are related with ozone generation.

6. Desalination

Desalination refers to the removal of salts and minerals. More notably, salt water is desalinated to produce fresh water suitable for human consumption or irrigation. Portable desalinator products are especially useful in dire emergency situations out at sea. Pick one up for quick & easy purified drinking water if you're headed for an ocean adventure.

7. Iodine Treatment

Generally, this treatment is one of many portable water purification systems that can be used by anyone who must acquire drinking water from untreated sources. The iodine kills various, but not all, of the most common pathogens existent in natural fresh water sources.

The procedure is as follows:


  • Water can be warmed first in the sun before treating or hot water can be added
  • Add 5 drops of iodine per quart when the water is clear or 10 drops per quart when the water is hazy
  • Waitfor at least 30 minutes before using or drinking

Iodine as water purification tablets is also available for those in need of field purification. This kind of tablet can serve as the best lightweight camping water purifier.

8. Ultraviolet Germicidal Irradiation

Ultraviolet water purification is a decontamination technique that uses ultraviolet light at appropriately short wavelength to eradicate or inactivate microorganisms. UV water purification is fast and compares positively with other water purifier in terms of cost and labor.

UV light water purification stops microbes from replicating making them far less hazardous. Water treated by ultraviolet water purifier is about the healthiest water that you can probably drink. Still, water that was preserved under a UV light water purifier must not be exposed to visible light for any weighty period of time before drinking to avoid consumption of reactivated microbes.

9. Solar Disinfection

This is a type of portable water purification that uses solar energy to make biologically-contaminated water safe to drink. There are three main subsets of solar water disinfection –electric water purifier, heat purification and UV purification. The gist in this is that microbes are annihilated by the temperature provided by the sun which makes Solar Disinfection suitable as a travel water purifier.

10. Solar Distillation

This is a practical manner of distilling water using the heat of the sun. Great for any water purifier camping situation, solar distillation can be done when a makeshift still can be constructed simply from readily available components to be a portable water purifier. It is then placed it over a small pit that is burrowed into the ground so that it can be used to make safe drinking water from unnatural water sources.

11. Filtration through Winnowing Sieve

When the water source is contaminated by wind-borne filth such as dry leaves, this type of filtration is best utilized. However, this method cannot be used when the raw water is highly turbid or muddy, since the sieve cannot filter fine suspended particles in raw water.

IN A NUTSHELL: Raw water is passed through a winnowing sieve – a tool of wire mesh or closely holed metal or plastic – and the impurities are filtered

12. Filtration through Cloth

This is most suitable for filtration of well water as it can only filter raw water containing impurities such as plant debris, insects or coarse mud particles. The gist in this type of Do-It-Yourself filtration is that a thin white cotton cloth or a discarded garment is used as the filter medium.

13. Filtration through Clay Vessels

Clay vessels with a suitable pore size are used widely in Egypt to filter highly muddy water.


  • Turbid water is collected and placed at the bottom of the big porous clay jar and is allowed to settle down
  • Then the water in the jar will trickle through the porous clay wall of the jar

14. Clarification and Filtration through Plant Material

This type of water filtration uses nuts or roots and cloth filters to purify highly turbid water. Generally, the result of this method is a jar of filtered water that is very clear and has a pleasant smell. Looks can deceive, folks...

15. Jempeng Stone Filter Method


This type of filtration can be best used as a village water treatment since there is no operational or maintenance cost such as for cleaning.


  • Put the jempeng stone filter units which are carved out of a porous material called ‘cadas’ in the artificial ponds
  • And let the muddy water filters through the porous wall of the filter unit as it gets collected inside

16. Dungeness Crab Shells and Nopal Cactus Gel Purification

These natural products can filter out the metals, iron and copper dissolved in water. This method is the most environmentally friendly way to cleanse water by recycling.

17. Membrane Filtration

This is a physical filtration process where a contaminated fluid is passed through a thin layer of semi-permeable membrane to separate microorganisms and suspended particles from process liquid.

18. Flocculation

When impurities cannot be removed by other water purification methods, Flocculation can come to the rescue. This process constitutes a vital part in the treatment of surface water or of waters with high-level of contamination.

19. Aeration

Today, aeration is applied generally to ground waters, for the removal of iron, and then of manganese, and also to eliminate malodorous gases from sulfur bearing ground waters.

In aeration, water is sprayed into the air to raise the oxygen content, to break down stinks, and to balance the dissolved gases.

20. Pressure Sand

This type of water purification method is often used to remove suspended solids from water. The filtration medium comprises of several layers of sand with a variety in size and specific gravity and this must be back-washed regularly.

21. Sedimentation

Sedimentation is a physical water treatment process using gravity to remove suspended solids from water. This is the primary treatment of sewage in removal of floating solids.

22. Slow Sand Filters

Using slow sand filters does a limited bacteria removal but can produce very high quality water free from pathogens, taste and odor without the need for chemical aids.

23. Direct Contact Membrane Distillation


  • Heated seawater is circulated along the surface of a hydrophobic polymer membrane
  • Evaporated water passes from the broiling surface through pores in the membrane into a stream of cold pure water on the other side.

24. Gas Hydrate Crystals Centrifuge Method

Gas hydrate crystals are formed when carbon dioxide or other low molecular weight gas is mixed with contaminated water at high pressure and low temperature, and in order to purify the water, this centrifuge method should be performed.

25. In Situ Chemical Oxidation

This is a form of innovative oxidation technology used for soil and groundwater purification to lessen the concentrations of targeted environmental contaminants to tolerable levels.

"ISCO" IS PRETTY MUCH THIS: The process of injecting strong chemical oxidizers directly into the contaminated channel to terminate chemical contaminants in place.


At the end of the day, purifying our water is more important now than it has ever been in human history. Our species will only continue to ravage the world with every year that passes and clean, potable water will become harder and harder to come by.

Hopefully this article has helped you on your quest for thirst-quenching purified water. Happy Purifying!
