With more than one lakh people in India dying of water-borne diseases, it has become important to ensure that you have access to safe and clean drinking water. Gone are the days when boiling water was enough to make it suitable for drinking. Environmental degradation and growing population have resulted in an increase in water contamination and pollution making it essential to purify the water before consumption. This is where an efficient water purifier system comes into the picture. A water purifier not only removes excess salts, minerals, suspended materials, and microbes but also retains the essential vitamins and minerals.

Types of Filters In RO System

These water purifier systems use different types of filters for purification purposes. You would find that filters like RO, UV, activated carbon and UF are added, which works in an efficient way to purify the raw water and make it pure and safe for drinking. Let us discuss the different types of filters present in water purifiers, and comprehend their functionalities

1. RO filters

If you live in an area where the water has a high amount of dissolved minerals, you need to opt for an RO water purifier. Reverse Osmosis (RO) filters use a multi-stage filtration process to purify water. The filters use a combination of active carbon particle filtration processes to remove the impurities. The filters have a membrane with very small pores that helps in removing micro-organisms. RO filters also help in improving the taste of the water that you drink.

2. Activated Carbon Filter

The activated carbon filter is ideal for removing soluble gases such as chlorine, ammonia, carbon monoxide, and ammonia. The water purifier also helps in filtering organic matters such as leaves or algae. The activated carbon filters are porous that easily absorb chlorine and pollutants such as pesticides. The residential carbon filters also have a lining of activated silver that helps in killing bacteria. Activated carbon filter-based water purifiers are, however, not recommended for areas that receive water with high TDS.

3. UV Filters or e-boiling

As the name suggests, these water filters use ultra-violet light to kill germs, bacteria, cysts, and microbes present in water by attacking their DNA cells. The simple and effective process can remove almost 99 percent of the harmful organisms present in water. The filters have a small mercury lamp that produces short wave UV radiation. These radiations penetrate the cells of the viruses and bacteria, thereby destroying the ability to reproduce. The purification method only kills the germs. You need a separate filter to physically remove the germs. UV filters are ideal for purifying water that is biologically unsafe to drink.

4. UF Filters

UF filters have membranes that are similar to the RO membranes but with larger pores. The membranes in the UF filter help in removing pathogenic organisms and colloidal particles. UF filters, however, don’t remove dissolved salts and solids from the water. UF filters are ideal for purifying soft water with less TDS. In short, UF filters are ideal for the pre/post-filtration process.

Essential Points to Consider

The essential pointers will help you select the right RO water purifier system that is ideal for you.

  • Check the water quality before purchasing a water purifier
  • Storage Capacity: You need to check the storage capacity of the purifier before purchasing
  • Find out about the different purification stages. More stages of water purification ensure the availability of cleaner water.
  • Check the purification technique as each method has some limitations when it comes to eliminating impurities
  • Check the total quantity of water it can purify to ensure that it meets your requirements
  • Check the certifications to ensure that the product has been tested and meets all the quality standards

Last Few Words

There are a large number of RO water purifier systems that use different purification methods and filters to make water safe for drinking. A majority of the water purifier systems use a combination of different filters to make water safe for drinking. Though the water purifiers that use a combination of filtration processes may be expensive, it is worth the expenditure considering the health benefits and safety that these purifiers offer.
