How to Purify Water at Home?

por Dr. Jonathan Doyle - Updated March 25, 2024
Purifying your water at home is the best way to guarantee the quality and safety of the water you drink and use. Of course, municipal water treatment plants are known to supply purified water, but toxins may still be present due to the aging infrastructure or environmental causes. So, purifying water at home provides you with an extra layer of protection against potential health hazards caused by pollutants.

Methods to Purify Water at Home

Purified water is important for household use, such as cleaning and cooking, because it keeps these pollutants at bay. It also improves the overall taste and odor of the water used, making water intake more desirable.
It prevents infection complications through bacteria, viruses, and parasites that may survive traditional therapeutic methods and exist freely in your water. There are various methods of hoke water purifying systems, and all of them seek to target and remove harmful toxins to improve your health and wellness. Now that you know why home purification is essential, let’s discuss the options available to you.


When you are unsure about the safety of your water source, boiling water is an easy yet very effective way to purify water at home. This affordable and reliable method acts as the first line of defense against invisible dangers, such as bacteria and parasites that may be present in water and pose a health concern.
Depending on your altitude, bring clean water to a rolling boil and leave it there for the suggested amount of time - usually one to three minutes - to start the purification process. The lower boiling point of water at higher elevations means that living there requires a longer boiling time. Before drinking, cover the boiling water and allow it to cool.
Let compounds settle well in the water before filtering it to ensure safer and clearer water. The quality of the boiled water is generally improved by filtering hazy water through a cloth, towel, or water filter to assist in removing bigger particles and contaminants.
Boiling does not eliminate all impurities, including metals, salts, fuel, hazardous compounds, and radioactive materials. So, if these problems are present in your area, you might want to consider more technical approaches for a better solution.

UV Light Purifier

UV water purifiers use ultraviolet radiation to disrupt the DNA of bacteria, viruses, and other pathogens, making them unable to replicate and ultimately killing them.
To purify water with a UV light system, first, ensure that the water is free of sediment and particles that could shield bacteria from the UV light. Many UV purifiers include pre-filters to alleviate this risk. For maximum UV exposure, place the water in a clear container; the success of these systems is dependent on its direct contact with the water being treated.
UV Light Purifier
Once the setup is ready, turn on the UV purifier. The UV lamp emits a specific wavelength that disrupts the genetic material of microorganisms. But they do not remove physical impurities, chemicals, or heavy metals as well. So, for a wholesome home water purifying system, you might want to consider other alternatives. Combining UV treatment with other filtration methods, such as activated carbon filters, is also an excellent way to get pure water at home.
UV Light Purifier
There are two common types of UV technologies used in water filter systems for homes . These are the low-pressure mercury vapor lamps and the sophisticated light-emitting diodes (LEDs). The usual choice has been low-pressure mercury vapor lamps, which generate UV radiation with a low wavelength and are particularly effective at neutralizing bacteria. However, these lamps contain a small quantity of mercury, which means you must be careful with handling and disposal.
UV Light Purifier
UV purifiers with LED technology, on the other hand, have grown in popularity due to their increased energy efficiency, longer lifespan, and mercury-free composition. LEDs may emit UV light with various wavelengths for the targeted removal of specific disease pathogens.


Distillation is another safe at-home water purification technique that uses evaporation to remove impurities. In this process, large, non-volatile organic molecules and inorganic chemicals are removed from contaminated water by heating it to the point of steam. The result is pure water, devoid of impurities such as lead and nitrate when the steam cools and condenses.
Distillation also works well to eliminate microorganisms like bacteria and some viruses by boiling them off, in addition to removing inorganic contaminants. But there are subtleties to the approach. While it is excellent at eliminating some organic compounds because of their solubility and boiling points, substances like toluene and benzene that have lower boiling points than water have the potential to evaporate with the water and recontaminate the filtered product if they are not appropriately treated before condensation.


The primary filtering processes that are a part of our daily lives usually include pitcher or faucet-mounted filters. These filters use activated carbon to trap contaminants and improve water quality. However, for a more wholesome experience and better results, there are many water filter systems for homes, which will be discussed below.
Under-sink Water Filter System: It is subtly tucked under the kitchen sink and usually uses several filtration stages that include carbon and sediment filters to get rid of particles, chlorine, and other pollutants. You can easily integrate this filter into your existing plumbing system because of its location.
Under-sink Water Filter System
Countertop Water Filter System: This home water purifying system is a self-contained unit that sits on the kitchen counter and does not require complex installation. It helps purify water using activated carbon, ceramic, and reverse osmosis technologies. It is one of the most convenient methods because of its convenience, mobility, and adjustability.
Whole-house Water Filter System: This system ensures that every tap in your home provides purified water, so It’s often used to replace water purifiers for sinks and other set-ups. It usually includes a succession of filters and, in some cases, water softeners, which provide extra water treatment at the point of intake. The water purifier system cleans your drinking water and provides benefits for bathing, cooking, and other home activities.
Whole-house Water Filter System
Each type of water filter provides its own set of benefits. Under-sink filters are covert and ideal for a single water source, countertop filters are portable and simple, and whole-house systems offer a complete solution for the entire house.


Chlorine-based compounds such as chlorine gas, sodium hypochlorite, or calcium hypochlorite are frequently used in a typical chlorination process. These commercially available chemicals offer an affordable method to purify your water at home.
The most prevalent method is household bleach, which typically contains sodium hypochlorite. This chemical is added to water in precise amounts to disinfect without affecting the taste or safety. Although chlorination effectively destroys bacteria, viruses, and parasites, it doesn’t permanently remove all chemical pollutants or impurities. As a result, assessing water quality and potential contaminants is crucial when deciding whether to chlorinate.
You can choose from a number of chlorination treatments, depending on your preference. One of the most popular options is chlorine tablets or granules. After adding them into the water following the instructions, the tablets progressively decompose, and chlorine is released into the water. Another option is dose management with liquid chlorine solutions, such as bleach.
To achieve the best outcomes and prevent unintended additions, always use chlorination products made especially for water treatment. Also, knowing the right amount of chlorine to add is important. Adding too much or too little can result in a disagreeable taste or potential health risks.

Reverse Osmosis

Water molecules use the process of reverse osmosis to move across a semi-permeable membrane, leaving contaminants behind. Numerous contaminants, including bacteria, viruses, minerals, and other particles that could compromise the taste and safety of your water, can be successfully removed by this method.
Reverse Osmosis
You can install reverse osmosis systems as countertops, under-sink, or whole-house water filters in your residence. The benefit is that it purges contaminants while also improving the taste and smell of your water. It’s a cost-effective, green solution that lessens the demand for bottled water and promotes sustainability.

Which Home Water Purifying System Is Best For You?

Reverse osmosis (RO) is a reliable method for eliminating various pollutants, including viruses and bacteria. For cooking and drinking, it offers thorough cleansing and can be installed as a water purifier for the sink and connected to all taps in the house. Filters like the Waterdrop 3-Stage Whole House Water Filter System work well to improve taste and remove Iron and Manganese from your water throughout the house.
Home Water Purifying System
Distillation works wonders for getting rid of some pollutants and minerals too. UV radiation may not completely eradicate all contaminants, yet it effectively disinfects. Boiling is a basic way to eliminate parasites and bacteria, but it leaves other impurities behind.
So, the ideal water purifying system for you depends on your unique preferences and requirements. To choose the best system for your needs, think about your preferences for flavor, ease of use, and the kinds of contaminants that are present.


When it comes to thorough purification, Reverse Osmosis System is a great idea. Alternatively, systems like Waterdrop 320-gallon Long-Lasting Faucet Water Filter that use filtrations work well for countertop and single-outlet sources with better flavor for your everyday use.
Boiling offers a straightforward way to eradicate microorganisms. Minerals are effectively removed by distillation. Meanwhile, UV light is adequate but might not be able to remove all impurities. Hence, as we’ve discussed, the choice between distillation, boiling, UV light, filtration, reverse osmosis, or any other option depends on what you need.
