Buying Guide

In Brazil, more than half of the population does not have access to drinking water. Those who have it are a little afraid about the quality of this water, so much so that they resort to homemade treatments to treat it and use the water purifier for this purpose.

The water coming through the supply system is in fact unsuitable for drinking. Despite receiving treatment, she suffers contamination during the passage in the pipes, where she finds substances harmful to health.

If you want to install a filter or water purifier in your home, continue with us. We will talk more about them and you will be able to choose the best one for you and your family.

What is a water purifier and what are its advantages?

The intake of filtered and treated water is very important for the proper functioning of the organism, especially when the weather is dry and the humidity of the air is low.

Untreated water can transmit several diseases, mainly related to the stomach and intestines. These diseases can come from both the water we drink and the food we eat.

To avoid contamination of water and food, it is very important to purchase a water purifier. This solution is more efficient and economical, although the investment is greater at first.

With purified water you can also cook and minimize the risk of food contamination. In addition, water without odors and unpleasant flavors allows the food to be even more tasty.

The water that comes out of the tap enters the water purifier through a thin membrane and the filter retains bacteria, germs, viruses, microbes, heavy metals and other substances that are bad for your health in the long run.

These filters have three to seven levels of filtering. Thus, when it arrives at the water reservoir, it is already clean, crystalline, and ready for consumption.

One thing that must be taken into account when choosing a water purifier is to think about where it will be installed.

There are countertop and faucet models, whatever your option you will need to take into account the dimensions of the appliance (height and width) and reserve a kitchen space just for the filter. Countertop appliances can also be installed on the wall, making it easy to find a space in your kitchen for it.

We have prepared a table with the main advantages and disadvantages of having a water purifier in your home, check below:

How does the water purifier filter process work?

Purifiers subject water to three stages of filtration. The first is filtration, which eliminates solid particles such as sand, clay and rust. The second is sterilization that eliminates microorganisms such as bacteria, viruses, fungi and microbes.

The third and final phase is the absorption phase, where they are eliminated: excess chlorine present in the water, chemical elements and heavy metals such as mercury and lead which, even in small quantities, are very harmful to health, especially in the long run.

It is necessary to change the filter of the water purifier approximately every four or six months, because in that period a volume of water is consumed that saturates the filter’s retention capacity. Some models have more durable filter refills with a service life of up to one year.

If you do not change the filter cartridge regularly, the water is no longer filtered and dirt residues start to clog the pores of the filter, making the water contaminated.

The most modern models have devices that emit an audible or visual signal indicating that it is time to change the refill of your water filter. This feature is very useful, as you may forget that the refill is out of use.

If your water purifier does not have this function, it has a very simple way of identifying when it is time to change the refill. Observe if the water flow has decreased, that is, if it is leaving in less quantity and taking more time.

This is because the filter is already clogged with impurities. With clogged pores, water passes with difficulty. Another characteristic to be observed is the color and smell of the water, if there is any change, then it is time to change the filter cartridge.

How to change the water purifier refill?

To change the refill is very easy. Buy a model compatible with your water purifier, turn off the water supply (in some cases you must close the valve) and open or unscrew the filter compartment cover.

Remove the water hose and clean the part (cleaning the filter on the outside and inside is very important). Empty the reservoir, use a cotton swab to clean the smaller parts and wash the larger parts with running water like the reservoir itself.

Then, remove the old filter and discard it (it cannot be reused), and insert the new filter. Turn on the water drive and let it run for about five minutes, but do not drink that first water that passes through the filter, as it is not suitable for consumption.

See how easy it is to change the filter cartridge of your water purifier:

What differentiates water purifier models?

There are several types of water purifiers, we will detail each of the types below. At the end, let’s compare water purifiers with common filters and drinking fountains, check out:

Faucet purifier

Nowadays, some faucet models come with a filter attached or have an entrance for you to put one on. The filter tap has two activations: one for ordinary water and another for filtered water.

The coolest thing about this model is that it doesn’t use electricity to work. But this is also a disadvantage, as the tap filter has no water temperature control.

Another disadvantage is that this model is not effective in removing bacteria from the water, only impurities and active chlorine. Like water purifiers, the filter cartridge needs to be changed every six months to keep the water treated.

Compact wall

The compact wall scrubber is an excellent choice for those with a small kitchen, because besides being light and smaller, it can be glued to the wall, avoiding the need to stick it.

But you will need to have a water outlet for the water purifier only. An advantage is that this device does not use electricity, the disadvantage is that it only filters the water, does not leave it at another temperature.

Electronic Purifier

The electronic water purifier is the most modern model of water filter on the market. With it you can control the water temperature (from two to seven options) and the type of jet (continuous or moderate) automatically or manually.

These devices also usually have water filtration levels, most models have three levels, some even seven. The greater the number of filters that the water travels through, the less impurities it will have.

Refrigerated purifier

The great advantage of the refrigerated purifier is the water temperature control, which can be natural, cold or chilled. Some models have mixers, which allow you to leave the water at the desired temperature.

The most modern models come with a digital touch screen panel illuminated by an LED lamp. With the panel illuminated, you will be able to get that glass of water at dawn without having to turn on the kitchen light.

As this model cools the water, it needs to be connected to the mains, but don’t worry, as these devices have very low light consumption.

Some models of this type continue to function even if their electricity drops, as they have a water storage tank. But the water cooling function is compromised.

Purifier with compressor

The purifier with compressor is the most powerful model, with it you can make the water much cooler. It also cools up to a liter and a half of water (per hour) more than conventional models.

Generally the temperature control of the purifier with a compressor takes place by means of a rotary knob where it is possible to regulate the water cooling. And the compressors are not bad for the environment.

Check out what a water purifier with a compressor looks like:

Purifier with mineral salts

This type of filter uses mineral salts to remove chlorine from the water and kill bacteria and germs. Some models have activated carbon that eliminates resistant viruses and others have colloidal silver treatment, which fights hundreds of diseases, thins the blood and helps in the health of cells.

In addition to the various types of water purifiers, people often buy common filters such as clay, plastic or stainless steel or water fountains. Check out how each of these models works:

drinking fountain

The water cooler requires a gallon of mineral water, which must be turned upside down and fitted into the water waste container. Some models can be connected to the mains and thus also cools the water.

The gallon has a capacity of up to 20 liters and needs to be changed regularly. Because of the gallon exchange, this model has a higher expense over time. It also serves a limited number of people.

In addition, this model does not have a filtration system, so be aware of the quality of the water you are buying. Also pay attention to the cleaning frequency.

Drinkers can be made of plastic or stainless steel, the latter being more used in schools, gyms, shopping malls and other spaces with a large flow of people.

Common filters

Common filters have the ability to filter water because of the candle, a non-toxic polypropylene compound that retains solid particles like clay, rust and sand.

The candle also has a second layer, made of activated carbon, which promises to remove excess chlorine, odors, flavors and color from the water. But this model is not effective against bacteria, fungi or viruses.

The water filtering process is done by gravity, that is, the water or gallon is placed in the upper filter container and it passes, drop by drop, through the candle and comes out in another container, which stores the purified water.

We have prepared a table comparing the main characteristics of the water purifier and the common filter. Check out:

How much?

There are several types of water purifiers, from the simplest models that only filter water, to the most sophisticated devices, with temperature control, touchscreen panel, automatic activation, among other features.

The cheapest model that only filters the water costs over R $ 150. More sophisticated electronic models cost between R $ 400 and R $ 700. The most expensive water purifier costs up to R $ 1,500.



Did you know that water is indispensable for the lives of humans, plants and animals?

It covers more than 70% of the earth’s surface and it was because of it that the first forms of life emerged.

Interestingly, water also makes up 70% of a person’s body weight and is essential for the functioning of the digestive and circulatory systems, for the proper functioning of the kidneys, skin hydration and much more.

It is ideal to consume at least 2 liters per day, to keep the body functioning properly

Where to buy?

You can buy your water purifier at furniture and appliance stores.

You can also choose to buy a water filter over the internet, especially with the tips you are reading in this article, Amazon, among others.

The Amazon site is one of the coolest, because there you can compare models, brands and prices in list form. You can refine your search by price in ascending or descending order, by customer reviews, highlights and newer products.

Purchasing criteria: Factors for comparing water purifier models

In this last part of the text, we will talk a little about the main purchase criteria, that is, the characteristics that must be taken into account when buying a water purifier. Are they:

  • Purification levels
  • Temperature control
  • Storage capacity
  • Installation mode and location

We will detail each item better so that you do not have any doubts and get the choice of your water purifier right.

Purification levels

When we talk about purification levels, we can refer to two characteristics: levels of particle retention (range from P1 to P6) and levels of filtration (range from three to seven).

The level of particle retention refers to the size of particles that the filter is able to retain inside its pores. The P6 level retains only large particles, while P1 retains smaller and larger particles.

You discover this and other important information through the Inmetro seal, which is attached to the back of the device. Also note the reduction rate of free chlorine, which is identified by Seal C of Inmetro. This index ranges from one to three, C1 the best, as it can eliminate up to 75% of chlorine, and C3 is less efficient.

Also note the level of bacteriological efficiency, this last criterion is only certified as approved or disapproved.

The water reaches the filter inside the purifier and passes through at least three levels of filtration. The first one retains solid residues such as clay, rust and sand. The second level bars microorganisms. The third level absorbs chlorine and heavy metals.

Temperature control

The most modern water purifiers have water control and cooling. The choice varies between cold, cold or room temperature water.

There is a model that has up to seven temperature options, which are selected on a rotary knob.

Some models have a mixer knob and you can control the water temperature to your liking. But if you like cold water, the tip is to buy a filter model with a compressor, because in addition to being efficient, it freezes more quickly.

Storage capacity

Some models of purifiers in addition to filtering and cooling water, also have a water storage device. The coolest thing about this function is that if the electricity drops, you can still drink cold water for a few more hours.

The stored water is in a dispenser attached to the device and the capacity in liters varies from model to model. The lowest level is 800 ml and the highest is 2.5 liters.

nstallation mode and location

Purifiers can be wall-mounted, generally smaller and lighter, or table / bench, which are larger and heavier.

The wall ones are practical because they do not take up space, but require a more laborious installation. The table ones are practical because they can be removed from the place for cleaning or even in case of change of location.

Whatever your option, you will need to take into account the dimensions of the device (height and width) and think about where it will be installed.
