TOP 7 Types Of Water Filters And How They Work?

Home Tips

There are all kinds of water filters you can find on the market today, hence is no reason to drink unsafe water!

The variety of water filters available now offer not only the removal of pathogens and bad microorganisms, but also retain the minerals we need to grow strong and healthy.

However, can you pick any random filter type? You should know that not all can do a perfect job. Go for the filter type that is easy to set up, easy to replace, and that produces the best water quality you need.

Here’s a glance at the 7 different types of filters to remove contaminants and provide pure water.

1. Reverse Osmosis (RO) Filter

This type of water filter uses a semipermeable membrane for purification. The membrane separates harmful molecules from water molecules by blocking larger molecules later flushed away.

RO filters are pre or post-filters to remove pollutants, viruses, and heavy metals. The filter requires high water pressure and electricity to work, and though pricey, they outperform most filters.

2. Ultraviolet Light Filter

A UV water filter uses light beamed at a high frequency to purify water through a glass material. UV light irradiates water, killing microbes and sifting contaminants.

Inorganic impurities are the weak points of UV light as it fails to eliminate inorganic impurities like arsenic, chlorine, or fluoride. UV light is also almost ineffective against many sediments and visibly unclean water.

For an effective water filtration system, don’t use UV light as a standalone, it works best as a post-filter.

3. Activated Carbon Filter

Carbon filters trap pollutants in their pores by bonding carbon to water molecules. The number of pores on a carbon filter determines the filtration rate. So you can maximize sifting by refining the carbon filter to activated carbon or activated charcoal.

Carbon filters, just like reverse osmosis, are used as pre-filters and post-filters to:

  1. Sift harmful molecules like mercury and lead
  2. Remove volatile organic compounds (VOCs).
  3. Reduce alkalinity by eliminating chlorine.
  4. Generally, improve the taste and quality of water.

But, carbon filters are useless against inorganic compounds like nitrates and fluoride, so you might have to use them alongside another filter.

4. Activated Alumina Filter

Activated alumina is refined aluminum oxide (Al2O3), the same substances as sapphire and ruby, without coloring impurities. The filters purify drinking water by removing arsenic, fluoride, and selenium from the numerous pores on the material.

Frequent usage of activated alumina can leach aluminum into the water or increase its composition in treated water, negating its original purpose.

5. Distillation Filter

Distillation as a form of water purification—unlike newer methods like UV light—is as old as time. From time immemorial, households have procured ample water quantity and quality using distillation.

The process is as simple as effective:

  1. Boil water into steam (vaporization).
  2. Wait for the water to cool off into liquid (condensation).
  3. Then store and seal your pure water in a clean container.

Distillation may be unsuitable for large families because the process requires stable electricity; only to generate a small amount of clean water.

Although distilled water tastes better and is free of microbes and some minerals, distillation filters cannot effectively sift chlorine and other VOCs.

6. Ion Exchange Filter

An ion exchange filter treats water using resins to provide healthy water for you and your loved ones. The resin replaces harmful ions with human-friendly ions. For example, it swaps calcium and magnesium for sodium. The resin also reduces alkalinity by removing chlorine and sulfur.

You must regularly recharge the sift with harmless substitute ions if you want an optimized ion exchange filter.

7. Mechanical Filter

Mechanical filters comprise small holes best used to purify large quantities of water containing dirt, particles, sediments, microbes, and pollutants.

While these filters might not be the best option to remove chemical contaminants, mechanical filters are a decent pre-filter choice to expel pollutants.

8. Refrigerator water filters

These work through a chemical reaction, for instance, between chlorine and activated carbon (AC). The AC purifies the water by absorbing all filth in the water and neutralizing harmful chemical substances such as pesticides and herbicides. This improves the water quality and taste.

Water Filters for Refrigerators, however, are most effective at removing chlorine. Their effectiveness at eliminating other matter depends on temperature & contact time the water has with the filter.
