How to choose a good water filter

Water, along with air, is the most important substance for human survival, a mature man can only last for 3 days without water. However, when we consume water from the public supply network, it is contaminated with chlorine, used for its bactericidal properties to remove sediments, bacteria and parasites or other particles, depending on the operator’s disinfection quality and maintenance of the network of pipes through which it is delivered.
To enjoy a drinking water, with no taste, smell or suspicious color, we advise you to purchase a water filter. Before you ask “where do I find water filters at good prices?”, You have to decide which models fit your needs. In order to do just that, we invite you to consult the following guide, where you will find out what types of filters are available on the market depending on the technology used and the type of mounting.

From the perspective of the destination, the water filtration and purification systems are divided into:

  • filters for the whole house: softening stations;
  • kitchen filters: microfiltration, ultrafiltration, reverse osmosis, UV sterilizers, alkalization;
  • bathroom filters: anticalcar, the shower head;

For those of you who are looking for a solution to counteract the hard water that causes the limescale to be deposited on the sanitary components or on the washing machine, then a good option is the ion-filter water filter with deionization and softening effect. The product uses an ion-exchange resin, but it does not have the ability to remove organic pollutants.

Fiber-water filters are particularly suitable for domestic hot water sources because it separates sediment, sand and rust. These are made of glass, cellulose, or rayon, so they are not capable of removing organic contaminants.
Reverse osmosis filters can be used to eliminate a large number of contaminants, purifying the water by passing it through a porous membrane that prevents the passage of salt and all harmful substances. According to some studies, this type of filter is able to separate over 99% of the common pollutants from the water.

Ceramic cartridges are generally indicated for preventive use, for water that is generally good for drinking and no major contaminants would be able to do any harm That’s because it can filter contaminants of only 0.3-0.8 microns, enough to eliminate microorganisms like Giardia or Cryptosporidium. In order to enjoy protection against harmful chemicals, you can get into the water reserve and install a ceramic filter with activated charcoal, or zeolite, the latter being able to bind heavy metals.

Ultrafiltration utilizes capillary membranes and has a filtration fineness of 0.01-0.03 microns, namely bacteria, viruses and other pathogenic microorganisms. Also, ultrafiltration equipment also uses a 5-pole filter for rust, malt, an ion exchange component that binds heavy metals and activated carbon to organic chemicals.

The latest water filtration technology uses nanofiltration, which, in addition to microorganisms and chemicals, will also reduce mineral concentration in water, with calcium and magnesium salts being removed by up to 50%.

According to the mounting type: When choosing the filtering method, you should also keep in mind the way you use it. For example, if you only want drinking water and you prefer the advantage of portability, you will choose a filter cup. The disadvantage of this type of equipment is that it can only produce enough water for 2 people.
If you want a filter that will provide you with an increased water flow, you can choose between different models, such as a battery filter, a sink filter or a filter for the whole home.

The battery filter will be mounted on its stem and will provide you with clean, no-smoky, no-smell flavor when you need it, the flow depending on the model. Most of the time, this type of equipment is provided with a filter switching system and this can be interrupted when using hot or cold water for domestic purposes to prolong the filter’s life. It is also easy to install and maintain, the cartridge can be easily replaced, even by you, without any professional help, which keeps the usage costs to a minimum.

The filter under the sink will be mounted directly on the cold water pipe feeding the respective sink. Due to this, you will need a second battery, so the filtered water does not contaminate passing through the same battery as domestic hot water. This type of filter provides a high flow of purified water for cooking and drinking and its placement will not hinder your daily activities.
Moreover, you will not have to switch from cold water to hot water to prolong the service life. The disadvantage of this type of water filter is that it must be installed by a professional installer to avoid possible misfortunes such as flooding.

The entire house filter purifies all the water that will enter, including the household water. It will be chosen according to the filtering capacity, which must be proportional to the amount of water consumed in your family. These are especially used to remove rust, shore and other macroscopic contaminants, but microscopic ones can pass, so it is recommended to use it together with another type of filter, for example carbon or fiber, to remove bacteria and chemicals. As a rule, home-only filter packages include sink filters. Similar to the above model, it is recommended to use a professional installer to mount the product.

Once you have considered all of these aspects and decided what kind of device is best suited to your business, it’s time to buy and find out what’s the answer to “where can I find a water filter at a good price?” We advise you to choose online stores.

How to use water filters

Today everyone is in search of the best drinking water, especially since most of the facilities found in the building blocks are old, so the water is most likely unhealthy (because of rusty and dirty pipes), and this is why, users who consume water directly from the valve can be facing iron, copper or aluminum poisoning, which can lead to skin, bone and even eye damage. Therefore, no wonder the water filters enjoy such great popularity. However, to obtain purer water, you need to have some information on how to properly use the water filter.

How to install the water filters

It is no longer a secret for anyone that there are water filters that can be mounted above the sink, underneath it or on the main fluid supply pipe, but knowing where the device can be installed does not mean you can actually install the water filter. That being so, our advice is to carefully read the users’ instructions to ensure that the fitting is done safely. At the same time, it is advisable to use the connectors in the package.
And although it is not necessary to have a technician to install the water filters, this can be done easily with the help of a drill and divers, it would not hurt to resort to someone’s help, so as to prevent unpleasant incidents that may occur during the installation(ex. floods ).

The steps to be taken when fixing such a device are: stopping the water supply in the house; opening the battery taps in order to reduce the fluid pressure; connecting the lime to the cold water supply pipe; optimal isolation with the teflon strip of couplings; diverter installation (tap water); appropriate positioning of the filters and connecting all the tubes with which your model is provided.

How to maintain water filters after installation

When you buy a water filter, you basically say “goodbye” to the involuntary ingestion of bacteria, chlorine, etc. of the water you consume, which is why more and more users want to know how they can properly care for the product after they have bought and installed it. Well, the truth is that all you have to do is change the filter cartridges regularly, according to their life span and your pace of use, and you will have purified water at home. Are you afraid that a water filter will cost too much? Check our article on the best water filters for under $200.

How to change the filter cartridge and how often you must do it

Filtration systems are designed to produce a certain amount of water over a period of time (most have the ability to purify under optimal conditions up to 5000 l / H2O), which means that once this limit is exceeded, the cartridge should be changed to prevent bacterial proliferation. The operation lasts only 5 seconds, so replacement can be done by anyone.

As to the frequency with which it needs to be changed, we would like to emphasize that in the case of correct installation and use, the filter cartridges (polypropylene, activated carbon and softener) are replaced once every 6 to 12 months, depending on the quality of the inlet water, whereas ultrafiltration, alkalinity, and reverse osmosis membranes have a life span of between 12 and 36 months, but this is influenced by the amount of filtered liquid.
