The primary purpose of a filter is to purify water by removing most impurities. Most people in India use purifiers containing reverse osmosis filters. The latest designs of these can also contain other purifying systems as well. However, most people lack knowledge about these filters.
This often results in individuals being unable to decide which filter is the best for them. All filtration systems have their own merits and demerits. One can search more about these on the internet.
For this purpose, they can use keywords like water purifier service near me in Patna. This can help them to know about each form of purifying filter. This can help one to know which filter is the best for them.
RO Filters
The RO filter is the most well-known water purifying filter among the common public in India. These filters use a reverse osmosis membrane to purify water. The membrane removes most solid impurities from water. These use chemical-based coatings that can also remove liquefied impurities as well.
Apart from this, such membranes can also remove the most harmful germs. There are two types which are cellulose and polysulfone based. These membranes alone cannot remove all impurities, and chlorine can damage them.
However, a combination of these two membranes neutralises such issues. One can easily maintain such filters by washing and cleaning them. One should use certain accessories that they can apply on these filters only.
However, one needs to replace such membranes once they get damaged. This is because such membranes are irreparable. However, the latest RO membranes are very durable and long-lasting. One can learn about these online. They can do this by using keywords like RO service near me in Patna.
UV Filters
Another filter is the one using ultraviolet light. These have electrical components such as a bulb. The bulb emits UV light. This light can kill most harmful germs in the water.
The filter does not use any chemicals and does not alter water quality. However, it does not use any membrane. Due to this reason, it cannot remove non-living impurities. Most purifiers use these along with other filters for purification.
UF Filters
Ultrafiltration filters work in a process similar to an RO filter. These use a membrane that can separate impurities from water. However, these are more capable of removing chlorine.
These can also be reusable depending on their type. However, these cannot remove germs and other solid impurities like RO membranes. Despite this, the latest UF filters have more efficient and durable membranes without these shortcomings.
NF Filters
Another filter that uses a membrane is the nanofiltration system. These use a membrane that can remove most multivalent ions from water. Due to this reason, these membranes can also remove hardness from water along with germs.
However, these cannot remove every other impurity from water. These also fail to remove chlorine from water as el. Despite this, the latest versions of these membranes are more suited to remove solid and chemical impurities.
Sediment Filters
Most purifiers use sediment filters at the beginning of purification. The filter uses sand-based techniques to absorb most solid impurities. These can include dust, pollutants and other things.
These filters are the best choice for removing most solid impurities from raw water. However, these might not always be able to absorb pollutants. These also do not remove germs and chemicals. This is why most cleaners use these, along with other filters.
Carbon Filters
Carbon filters use carbon-based techniques for water purification. These work together with sediment filters and can constitute the first and last purification processes. These filters can remove pollutants effectively.
These pollutants can include carbon-based ones or chemicals. These can improve the taste and smell of water. However, just like sediment filters, these cannot remove germs. Therefore, carbon and sand-based filters form any purifier’s pre and post-filtration systems.
Which Filter Is The Best?
All of the filters mentioned above have their strengths and flaws. Recently, these filters have become more efficient in doing their job. Their maintenance has also become more manageable. This is because one can clean or replace them when needed.
However, the maintenance of the sand and carbon filters is the easiest. One can clean or even repair these filters and replace them.
However, the membrane-based and UV filters are not very reparable. Despite this, the sand and carbon filters cannot do what the other filters can. All this shows that there is no so-called best filter. One must use all these filters in one purifier to get the best drinking water.
