Shopping guide

Filter system

So that you can acquire an effective product, one of the first characteristics to evaluate in this comparison of water purifiers is the filtering system.

Consuming water is vital for our health, but in some cases it can become contaminated with chlorine, metals, fluoride, pesticides, bacteria, parasites and other compounds that can be harmful to the body. Therefore, it is of the utmost importance that the water be properly filtered to reduce or eliminate these substances and heavy metals and thus be able to preserve the health of both yours and that of the other members of the family. Also, filtering improves the taste and smell in a general way to be able to ingest the water.

Among the different filtering systems there are products that, in addition to filtering the water correctly, are accessible, so you should not worry about how much a water purifier costs that can allow you to enjoy drinking liquid.

The purifiers have a system inside that can include activated carbon, stones, ion exchange resins or other elements that will help reduce heavy metals, substances and microorganisms that can affect health. Therefore, we advise you to take this feature into account among your options so that you can acquire a quality product.

Filter capacity and technology

All water purifiers have a limited useful life to carry out their work, so its durability must be evaluated to know how much time and drinking water we can count on.

These can come with a durability for weeks or by capacity in liters, being unusable after that and will have to be changed if they are disposable.

For this reason, we recommend that you select the water purifier that has disposable filters, since these are usually not that expensive and you can easily change them at the time, which will allow you to enjoy filtered water in a practical way.

On the other hand, among the technologies available in some models you can find activated carbon, ozone and reverse osmosis. Filters with activated carbon technology eliminate microorganisms, heavy metals and substances that may be present in the water, such as iron, lime, chlorine and pesticides. 

Reverse osmosis filters will only remove bacteria and ozone filters also remove microorganisms and bacteria, but it is not capable of reducing heavy metals and substances harmful to health. Therefore, we recommend that among your options you select one that has activated carbon.

purifier type

That is, if you want to buy a product for your home, work or a personal purifier, since there are models that have an installation system directly on the tap, portable and mobile. The former are commonly used in the home to treat the water that comes out directly from the pipe.

Additionally, you can move the purifying jugs from one place to another, allowing you to add the necessary water to be filtered, so they are practical products to have at home or take on excursions.

Finally, portable water purifiers are those that are small in size and will allow you to take them with you wherever you go, but they are made especially for adventurers, since inside they have a large capacity filtering system that will treat the water passing through it.

Therefore, we recommend that you evaluate your needs so that you can select a water purifier that is capable of meeting your expectations.

Materials and maintenance

Water purifiers can be found in plastic and metal, the former being safer and easier to clean, since their structure can have protection against bacteria, while metal ones could rust if they were hit and bring about reactions allergies or diseases.

Take advantage of the filter

If you have installed a water purifier in the kitchen faucet and you want to prevent your family from misusing the equipment, which would result in a reduction in the useful life of the filter, we recommend the following:

Try to keep the stopcock always activated so that water does not filter, as this will reduce the useful life of the filter.

Instruct your family members to turn off the faucet after washing the dishes and pots to prevent water from being wasted. In addition, if there are children under 5 years of age, it is recommended that they do not use the dishwasher without adult supervision.

Carry out the process of changing the filter personally and as long as it is close to reaching the limit. Not before, because if you do you would be wasting a few liters of water that you could use; but not afterwards to avoid diseases that could cause damage to your body.

General recommendations

So that you can keep bacteria and microorganisms away from the water purifier, we recommend that you frequently clean the structure of the equipment with a cloth with soap and chlorine, since chlorine is a powerful chemical that will help you disinfect any surface of microorganisms. who want to penetrate the structure of your purifier.

In addition, we also recommend that, when you go to change the cartridge, you take advantage and wash the structure on the inside with chlorine and rinse it with plenty of water so that you can use a 100% disinfected product.
