Everything You Need to Know About Water Filters

When buying a water purifier, it is essential to consider several important issues. Do not forget that there are several models and that not all offer the same level of purification. In this section, we will try to clarify the main doubts you may have about it.

Water purifiers are devices that use different systems to filter salts and other substances present in tap water. In this way, in addition to significantly reducing their salinity, they make the taste of the water more pleasant and eliminate possible odors.

What Are the Advantages and Disadvantages of Water Filter?

Water purifiers offer a significant amount of benefits, which is why their popularity continues to grow. You can find out the main pros and cons of the table we have prepared below.


  • They are cheaper than bottled water
  • They respect the environment more than plastic bottles
  • They are very easy to use
  • They allow filtering the excess of limestone, chlorine and other unwanted elements
  • With them, the water has a more pleasant taste
  • They can eliminate bad odors from the water
  • They help you save space in the kitchen
  • You don’t have to go out and buy bottled water


  • Some may require an installation
  • The filter jugs waste part of the water
  • If the filters are not changed when needed, they worsen the quality of the water

Who Is a Water Filter Recommended For?

In general, they are recommended to anyone, since urban water distribution systems cannot always guarantee that the water that reaches our homes is of the highest possible quality.

They are particularly recommended if you live in a place where water has considerably high limestone levels.

How Many Types of Water Filter Are There?

In principle, two types of water purifiers can be distinguished, which differ mainly based on the type of device from which one filters: the tap and the carafe.

The advantages of the first are that they take up very little space and that purified water is obtained immediately. The second one, on the other hand, can be taken anywhere, even when traveling or away from home.

On the other hand, the carafes waste a certain amount of water. Some manufacturers speak of a ratio of one liter wasted for every four liters filtered.

In any case, you can always reuse it for cleaning or other needs. There are also other alternatives, such as water distillers and electric water purifiers.

Advantages of A Water Purifier with Activated Carbon Filters

Activated carbon filters are made of porous material of vegetable origin, with the ability to absorb substances such as chlorine and a wide variety of organic compounds.

The enormous absorption power of activated carbon is the result of its microscopic structure, thanks to which it has an excellent ratio between its surface and its volume.

For this reason, activated carbon filters are distinguished by having a great absorption power and by making the water taste better and with fewer odors. It is currently quite common to use them as a complement to improve the various existing water purification systems.

How Do You Use a Filter Jug?

The first thing to keep in mind is that it is essential to change the filter with the frequency indicated by the manufacturer. Otherwise, its use can not only not be beneficial but can become harmful.

On the other hand, it is important to eliminate the water from the first uses of each filter. And finally, always put the carafe in the refrigerator.

Purchase Criteria

If you want to buy a water purifier, it is advisable to take into account several purchase criteria. This way, you can more easily find the most suitable product for you.

  • Purification level
  • System
  • Capacity
  • Filters

Purification Level

This is the first and most important aspect you should consider. Not all filter systems offer the same results. Logically, filter jugs are one of the least ambitious options in this regard. Something similar can be said of most models from taps.

Among these, one that guarantees a good level of purification is Water TAPP 1, capable of filtering more than 70 different types of contaminants.

An alternative for professional use is water distillers who, like Miracle that we have included in our selection of products, allow us to obtain distilled water. Of course, its price is generally higher.


Although the two main and most used water purification systems in the home are the tap systems and the filter jug, the truth is that they are not the only ones.

Also, there are several variations of these. A very original option is the Dropson filter can, which consists of a disposable and recyclable can, installed on the tap.

Its main advantages are ease of use and portability. Furthermore, it can be monitored with a mobile phone, although it is not the only one that allows it since the TAPP 1 tap water purifier also has this possibility.


Logically, the capacity of the filter jugs is lower than that of the tap systems. Models like those of AmazonBasics have a filtering capacity of 1.4 liters.

However, there are interesting alternatives for offices or gyms, “purification distributors,” such as BRITA Flow, which has a capacity of up to 8.2 liters.


About filters, you need to take into account the type of materials they can filter and their durability. Remember that filter life is generally expressed in several ways.

The most common is in liters, months, or weeks. Indicatively, a filter with a capacity of 1,500 liters may be sufficient for about three months. Of course, you also need to make sure you can find new filters when you need them. Don’t forget that cheap clothes are often expensive.

A purifier may be very cheap, but then you do not find spare parts for the filters, which means losing all the usefulness and abandoning it in the corner of the kitchen.
