What is a Water Filter Made of: Some Essential Facts

Spread the love

What is a Water Filter Made of and &? The way how filters work is something that is pretty much standard. It’s mainly because they all are based on one basic principle.

The type of filters basically comes down to how many stages the water undergoes before it’s free from contaminants. This is owing to the fact, that they have been constructed differently. Likewise, there is also a big difference as to what is a water filter made of and some essential facts.

The material that uses will determine the filter’s efficiency and durability.


Nowadays, water filter manufacturers are using a wide range of materials. Nonetheless, we will briefly discuss the most common materials, use to give you a better understanding of whether or not your municipal and home water is safe for drinking.

This will also help you understand why you absolutely need a water filter, for your home.

What is a Water Filter Made of?

These water filters, are made up of different materials and are also used in different situations. Hence, we will look into the filters used for homes, water-filtering plants, and portable filtration systems.

Home Filters

There still may be a need to add a filter even though, the water is treated in your municipality plants. By doing this, it will make your water drinkable and safer.

Water may pick up contaminants through pipes, faucets, elbows, and valves. Home filters can help, as they do a final absorption before you fill up a glass or bottle from the faucet.

The faucet-mounted and under-the-sink water filters, you can use at home come in different shapes and sizes. But, most of them are made of activated carbon only. Hence, one of the most common components, found in many small water filters is activated carbon. The filters center part is filled with activated carbon, and usually, have an external and internal plastic shell.


Other activated carbon filter models are more sophisticated. They have an outer alloy layer that can remove chemical elements like mercury, lead, copper, nickel, and aluminum. Also, this added protective layer inhibits the growth of bacteria or algae.

Benefits

Why activated carbon? Activated carbon is not overly expensive. Moreover, it is capable of filtering out a lot of impurities, contaminants, and germs out of the water. That is possible, because of the fact that it has a very high surface area.

Meaning, it has the ability to bond with large contaminants. Hence, solidify them before blocking them as the water passes down and comes out of the faucet.

Also, filters made of activated carbon have more pores and area for the absorption of compounds.  This is why they usually have a longer filtration life. Yes, you do have to replace activated charcoal filters. Especially once they have exhausted their ability to absorb these contaminants and compounds.

This is because these filters remove pollutants by simply absorbing impurities. Hence, once they have reached their limit, they become less able to absorb any forms of impurities.

Another reason why activated carbon is used in filters is because it will not filter out potentially healthy organic mineral ions.

This includes calcium and magnesium, which are also considering to be quite beneficial for your health. This means activated charcoal filters target only the harmful metal ions, which may be detrimental to your health over the long run.

Also, the activated charcoal filtered water is tastier and even smell better in comparison to other kinds of filtration systems. In some cases, the smell of sulfur water is diminishing.

Industrial Filters

Industrial water filtration systems are designed to filter out large quantities of water. The method of filtration may differ from one plant to another, and several layers of filtration aim to remove different pollutants or contaminants. Some filters have mesh materials for the first stage of the process. This will help them eliminate huge items like leaves, branches, or debris.

After that, the contaminants pass through other layers of filters, that are a form of different materials. Some may be biological in nature while others may have sand in them. Nonetheless, the principles are the same, but the execution and the size of the system are pretty different.

Filtration systems for industrial use usually follow a pattern which is:

  • mesh filter
  • antibacterial filter
  • activated carbon filter
  • lastly, another antibacterial filter

As can be denoted, there are more rigorous standards at these water plants. Thus, the filters create stronger materials. Therefore, the actual filtration and purification are more efficient in comparison with the small filters we use at home.

Nevertheless, those filters, form from small activated carbon layers are important. Since they serve as the final layer of filtration before you drink it. They are often referring thas a “polishing filter”.

Portable Filter Straws

As the world becomes more technologically advanced, many manufacturers and experts started developing smaller versions of every useful product. That is why today, you can already find water filtration bottles or straws that have filters in them. They design for outdoor adventurers, so that, they no longer have to carry a bottle of water with them.


Likewise, some organizations buy these products and donate them to countries or places that still do not have access to clean water.

These portable straws are usually integrated with filters, which are made with halogenated resin materials. These are capable of filtering out 99.99% of waterborne bacteria and parasites. Some can even remove 99% of viruses. However, these filters cannot filter out harmful and heavy metals. Also, these filters have a limited lifespan.

Once they have reached the total amount of water that they can filter, they need to be replaced. Some of these portable water bottles or straws, require regular cleaning, either manually or using an integrated backwasher system.

Summary

Since water is such an important commodity, knowing the type of filter your municipality is using is important. Also, when buying a filter for your home, make sure to buy from a certified company that meets all the health standards kept by NSF International.

In addition, if you intend to buy portable filters knowing what a filter is a form of, is even more critical. You may be drinking from springs, ponds, and taps from an area that you are not really familiar.

The other body components of the filter, usually form of plastic. You should make sure that it is BPA-free and strong enough to last long. Filter replacement time is mention in the user guide, or the packaging and varies from model to model.

Finally, once the filter reaches its replacement date, make sure to be prompt in changing the filter as it may no longer be able to serve its purpose. Nonetheless, water filter bottles, straw, and home filters are not really very expensive to replace. In fact, you can easily find them online.
