What is a Water Purifier?

A water purifier removes biological contaminants like algae, bacteria, parasites and viruses and reduces Total Dissolved Solids (TDS). Physical approaches to treatment include filtration, sedimentation or distillation.

Chemical treatments such as drops or tablets are also an option, but can leave a strong flavor and have limited effectiveness against protozoa including Giardia and Cryptosporidia.

1. Health

Water filtration and purification systems remove chemicals, metals, toxins, bacteria and other contaminants from the water in your home. The result is healthy, delicious drinking water that improves your quality of life by lowering your risk of illness and disease.

You can also use these machines to filter your pool for the same reasons. A water purifier is especially important if you live in an area where the tap water is heavily polluted with chemical and bacterial contaminants, or if you travel to places with questionable water treatment and sanitation infrastructure.

Some filters and purifiers can also remove viruses from your drinking water. These tiny organisms are too small to be caught by most filters, but can be killed using chemicals like iodine or bromine, which are often included with the product. This will prevent you from ingesting the dangerous germs that can cause diarrhea, Hepatitis A and rotavirus. You can even buy a system that combines water filtration and UV treatment for optimal protection. A water purifier is an excellent investment for your health, and it will help you keep your family safe when traveling abroad or in the backcountry.

2. Looks

There are many different water purification products on the market, some of which look pretty uninspiring. However, a few brands have gotten pretty creative with how they look whilst retaining their functionality. For example, the Steripen Adventurer looks like a pen that you insert into a bottle full of dirty water. After just 90 seconds, the device kills bacteria, protozoa and viruses and a light on the body tells you when the process is complete.

Other products, such as the LifeStraw Go and the Grayl Geopress, use a similar method to eliminate pathogens from your drinking water. They don’t remove viruses though so aren’t suitable for day to day travel in countries where tap water is contaminated.

If you want to make sure your purifier is safe to use, check that it has passed the EPA guidelines and NSF P231 standards with Type 3 challenge test water. You can find this information on the manufacturers website or by asking them for a copy. The most reliable brand will also have a certificate that shows how many litres of water the product can clean, which is a useful metric to know when shopping for one.

3. Style

Water filtration removes organic and inorganic matter, including dissolved solids and gases, from drinking water to make it clean. This can improve the taste of a water supply as well as reduce the concentration of chemicals and particles that may be harmful.

The best water filtration systems are usually mechanical and route water through a filter or microfilter to remove contaminants. This method of treatment is ideal for outdoor activities, particularly in remote or high-traffic wilderness areas.

Chemical and UV purification methods also exist, but they forgo filtering and are good options only when you have access to clear water sources like glacial streams. They’re typically a bit more bulky and require batteries and electronics to operate, which isn’t ideal for backcountry use.

The Sawyer One-Gallon Gravity Filtration System is a great option for backpacking and backcountry hiking in places like Torres del Paine. It works by using gravity to filter out sediment from water, but it doesn’t protect against viruses so isn’t a good choice for international travel or crowded backcountry areas. A SteriPen, on the other hand, is a more lightweight option that uses ultraviolet rays to destroy bacteria, protozoa, and viruses.

4. Function

A water purifier lowers the contamination level of a body of water to make it safe for drinking. This can be done by using a physical barrier, chemicals or UV light.

A purifier can also remove particulate matter like dirt from water. This helps prevent clogging of the filter and increases its lifespan. This process is called pretreatment and often involves sediment filtration or carbon filtration. It is used in situations where the water source is contaminated with large amounts of debris that can impede other water treatment methods such as UV or boiling.

In a purification plant, pretreatment may also include the addition of chemicals to control bacteria in pipes and tanks (prechlorination), deionization or other chemical treatments, and coagulation basins where low energy inputs turn large paddles to enhance clumping of metal salt coagulants or organic polymers. These are typically used in conjunction with gravity or pump-action microfilters.

Distillation and reverse osmosis are two other common water purification methods. These are more expensive than a carbon filter or physical purifier, but require less energy and are more efficient in eliminating harmful contaminants.

5. Price

Water purifiers are a great option for homeowners who want to make sure they have access to clean and healthy drinking water. They are also more cost-effective than purchasing bottled water, which can be very expensive over time.

A water purifier can help reduce the amount of chemicals and pathogens in your drinking water, making it healthier for you to drink. It can also improve the overall taste and smell of your water. It’s important to choose a water purifier that has the right capacity for your family’s needs, as well as one that uses a good quality filtration method.

KENT Supreme Alkaline RO+UV Water Purifier is a great choice for people looking for a new water purifier with a high performance and low price. It has a large storage capacity and multiple stages of purification. It also has a TDS controller and a smart sense indicator to warn you when the filter is going to expire. Moreover, it comes with a lot of other features that you won’t find in other water purifiers at this price range.
