What Are The Different Types Of Water Filters?

An essential component of any water purifier is its filter. The filter’s primary purpose is to remove contaminants from water and purify it. A purifier is incomplete and useless without this component.

There are different types of filters. Each filter differs from one another based on its design and efficiency. The costs of these can also vary very much. However, most people do not know much about the different types of filters.

A person can make better choices while buying a purifier by knowing about the different types of filters. One can also maintain their purifiers at the lowest expenses by learning about the features of their filters. One can contact reliable technicians by searching about them on the internet. A person can use keywords like water purifier service near me in Pune to conduct this search.

The Two Basic Categories Of Filters

A person can categorise water purifier filters into two types. These are pre and post-filtration systems. These filtration systems are a significant part of every multi-stage purifier. The pre-filtration systems form the first pathways raw water has to go through in a purifier.

These filters can remove most dirt and other impurities. This makes the water ready for further purification processes. These are also responsible for improving the taste and smell of water. A purifier can have one or more such filters.

The post filters tend to remove any remaining particles in water. These forms the last stage the water must go through in a purifier. These also help to enhance the taste of water and also add essential minerals to it

Both of these filters generally consist of either sediments or carbon. However, carbon pre and post-filters are more valuable than sediment-based ones.

Carbon And Sediment Based Filters

Some of the best filters are carbon-based. These use activated charcoal to absorb any water pollutants and unwanted substances. These can act both as pre and post-filtration systems. These filters can also improve the taste and smell of water by removing toxic impurities. These components do not require electricity for functioning and therefore save power consumption.

Sediment-based filters are another group of efficient filtration systems apart from carbon-based ones. These can also act as pre and post-filters. However, most cleaners use these as pre-filters only. These are less efficient than carbon filters for absorbing pollutants and improving water taste. However, these are more efficient in absorbing sand, dust and other particles from water.

These filters are also helpful in maintaining the purifier and its pipelines. These prevent dust particles from clogging the channels and purifier systems. Both filters are easy to maintain and only require regular washing.

Reverse Osmosis Filters

Reverse osmosis water filters are some of the most popular filters worldwide. One can know about them by searching keywords like RO service near me in Pune. These filters use a reverse osmosis membrane for functioning. These can remove solid and chemical contaminants as well as microbes.

There are mainly two types of RO membranes. These are thin film composite and cellulose triacetate membranes. One can use any of these or both coupled with other filters to get healthy water. These are also easy to maintain and only require a replacement after their warranty expires.

Ultra Violet Filters

The filters using ultraviolet light are efficient enough to kill microbes. The UV radiation from these filters can kill any germ in the water. However, these do not tend to affect the non-living impurities in water. Despite this, these filters are much more efficient in removing disease-causing germs than other filters.

The maintenance of these filters might be a bit costly. It is because these have electrical components that require technicians for servicing. However, one can still clean and replace them from home.

Ultra Filtration Filters

The ultra-filtration filters work in the same way as the RO filters. These use a membrane that helps separate all contaminants from water. However, these are much more capable than the RO membranes in this job. These are also more versatile and are available in several forms.

The maintenance of these filters can vary depending on the membrane type. However, one might need to wash these membranes regularly and replace them when needed. Despite these, one should still consult with technicians for their maintenance.

Other Types Of Filters

There are several other filters that most people do not know. One example of this is ceramic filters. These have tiny pores that can trap any impurity. These are also easy to install and durable due to their ceramic-based design.

Another underrated filter would be the one consisting of activated alumina. These consist of aluminium oxide that traps all impurities using adsorption. All of these filters are more durable and long-lasting and require easy maintenance.
