RO filtration is a type of water filtration system, but it differs from other filter systems in a few key ways, But in general they all help to purify and remove contaminates from your water.

  1. Mechanism: Unlike other filtration systems that rely on physical filters to trap impurities, RO systems use a semipermeable membrane to remove contaminants. The membrane only allows pure water molecules to pass through and blocks impurities.

  2. Efficiency: RO systems are highly effective in removing a wide range of contaminants, including dissolved salts, minerals, bacteria, viruses, and other pollutants. This makes them ideal for use in areas with hard water or high levels of contaminants.

  3. Maintenance: RO systems typically require more maintenance than other filter systems, as the semipermeable membrane needs to be cleaned or replaced periodically.

  4. Cost: RO systems tend to be more expensive than other filter systems, due to their higher level of filtration efficiency and the need for regular maintenance.

In summary, RO filtration offers a higher level of filtration efficiency and a wider range of contaminant removal, but at a higher cost and with more maintenance required.

Protecting yourself and your Family.

While the Environmental Protection Agency (EPA) regulates public water supplies, this doesn’t mean your water is totally free of certain contaminants like chlorine, asbestos, cadmium, copper, and fluoride. But in order to assess whether or not you should get a filter, you need to understand your water source and its potential contaminants.

The Centers for Disease Control and Prevention (CDC) recommends that if you get water from a private well, you get it tested at a state-certified lab at least annually. If you get water from a public system, you’ll get a report from the EPA on the quality of your drinking water that will come with your water bill and tell you what contaminants your water may have. You may decide you want a water filter just to improve the taste of your tap water, even if the poor taste isn’t due to anything actually harmful to your health. However, the CDC warns that many contaminants cannot be seen, tasted, or smelled. If you confirm your water source may have harmful amounts of arsenic, nitrates, chlorine, lead, or other contaminants, you’ll want a water filter that can specifically address those concerns.

Although the EPA regulates public water supplies, they may still contain contaminants like chlorine, asbestos, cadmium, copper, and fluoride. To determine if a water filter is necessary, it is important to understand the source of your water and potential contaminants. The CDC advises getting private well water tested by a state-certified lab at least once a year. For water from public systems, the EPA provides a report on the drinking water quality, which is included with your water bill and lists any contaminants present.

While some people may choose a water filter simply to improve the taste of their tap water, the CDC reminds us that many contaminants are not noticeable through taste, smell, or appearance. If harmful levels of contaminants such as arsenic, nitrates, chlorine, lead, or others are present in your water, it is important to use a filter that targets those specific concerns.

Different Methods Used to Clean your Drinking Water

Activated carbon

Activated carbon is sold as granules or solid blocks. Carbon removes contaminants through chemical bonding. It efficiently removes Chlorine, which improves water’s taste, while some will remove Chlorine and lead. Notably, carbon does not filter inorganic pollutants such as fluorides, nitrates, and arsenic. You will need a different filter if your water source is contaminated with these elements.


The method involves heating water until it vaporizes. The vapor is channeled to a condenser, which is reversed back to liquid. The process works great since water has a lower boiling point than most pollutants and microorganisms. The method removes bacteria, sediments, germs, salts, and heavy metals (lead, arsenic, and mercury).


De-ionization uses an exchange of ions in water to remove salts and other electrically charged ions in water. The filter removes elements that lack electric charges. This process does not remove bacteria and viruses.


Chlorine is a chemical that kills bacteria, parasites, and other disease-causing microorganisms in water. It is available as tablets or liquid Chlorine at very low prices. Chlorine tablets are dissolved at 12 degrees Celsius or higher. After using Chlorine, reverse osmosis can remove other contaminants in water for higher purity levels.

When using Chlorine, people with thyroid problems need to talk to a medical practitioner before using the water.


Filtration through different multimedia filters is a common practice in water purification. The method involves a chemical and physical process to eliminate pollutants and contaminants in water, making it safe for drinking. Small and large particles are removed through filtration. Since some chemicals are dissolved in water, it is useful for other procedures to be used. The chemical absorption processes remove unwanted compounds from water. Filtration is preferred to RO when it comes to removing pesticides and Chlorine. Less water is lost during his process, and it does not require a lot of energy. Filtration is also very cheap.

Ion exchange

The ion exchange technology uses resin to replace harmful ions with some which are less dangerous. The method is commonly used for water softening, replacing sodium, calcium, and magnesium with harmless ions.

Reverse osmosis

The reverse osmosis method (RO) is widely used in removing salts, impurities, and germs in the water. In this process, a semi-permeable membrane removes all impurities dissolved in water. The membrane has very tiny pores (0.0005 microns), which are slightly larger than the size of a water molecule. The shortcoming of this method is that it removes some essential minerals from water, thus altering its taste. Regular maintenance and replacement of the membrane could also be costly. How the RO water purifiers work will give you a clear picture of how it functions. Larger molecules like those of Chlorine are not removed in the process. The reverse osmosis system is efficient compared to carbon filters, making it a perfect domestic choice.


Mechanical filters remove larger pollutant particles. They cannot remove chemicals dissolved in water. They are handy with other filtration methods where the water is very dirty, and you must get rid of solid waste first.

Ultra-Filtration (UF) purification

UF (Ultra Filtration) works through a membrane similar to RO, but the membrane has bigger pores. The membrane removes colloidal particles such as pathogenic organisms and turbidity. The membrane fails to remove salts and dissolved solids. UF removes bacteria, microorganisms, and viruses from your water. The water obtained after this process has less TDS and is not very hard. With RO, the water has too many TDS and is very hard.


Ozone filters kill microorganisms in water but do not remove chemicals. They are used alongside other technologies for high efficiency.

Carbon block

The carbon filters have crushed carbon particles, which makes them more efficient than other carbon filters. The increased surface area gives them a higher sediment-holding capacity than most filters. It has activated carbon, which has millions of pores that absorbs substances from liquids.

Activated carbon has a larger surface area for bonding chemicals, trapping carbon-based impurities and Chlorine. Sodium and nitrates pass through the filter. The carbon block filter must be replaced for efficiency when the pores are clogged and stop working.

Granulated carbon

The filters use small particles of carbon to remove impurities in water. They have a smaller surface area, which lowers their efficiency compared to other block-shaped filters. Their filtration speed depends on water speed.

UV Purification or E-boiling

UV water purification uses ultraviolet light to kill germs, bacteria, cysts, and other microbes found in water. It destroys about 99.99% of microorganisms in water. The cleaner is built with a mercury lamp that produces UV radiations that destroy all microorganisms.

While the microbes are killed, their bodies remain in the water. A separate filtration system is used to get rid of germs physically. Carbon filters or reverse osmosis may come in handy in producing more purified water.

Water softeners

Water softeners use ion exchange technology to remove magnesium and calcium ions from water. The process involves using sodium in the softening process. The resulting water will have higher levels of sodium. If you do not need a lot of salt in your water, avoiding water softeners in your plumbing systems is useful. Water with high salt is also not suitable for watering plants.

Candle filter purifier

The candle filter has tiny pores that block larger particles. The candle does not need electricity to function. The candle needs to be cleaned frequently to unblock the pores for greater results. Water resulting from this process must be boiled to kill microbes.


Boiling water is the cheapest method of purification. Water may contain some bacteria and life-threatening germs that are invisible. Boiling water for 1-3 minutes kills most microorganisms in water. The boiled water is left to cool down before drinking. If you live in high-altitude areas, allow water to boil longer since the boiling point is slightly lower.

Fiber filters

These filters contain rayon, cellulose, and other materials designed into a mesh with tiny pores. Water is poured over the filter, and it passes through the pores. For this method, some pressure is applied to force water through the tiny wrapped filters. Check for a micron rating below 1 for high efficiency when buying a good filter.

Water purification is essential to ensure that water sources are free from impurities and contaminants that affect water safety. This process is done through various methods such as filtration, distillation, de-ionization, chlorination, ion exchange, reverse osmosis, mechanical filters, ultra-filtration, ozone, and carbon block. Each method has its pros and cons, and the most suitable method depends on the type of contaminants present in the water source. It is important to choose a water filter that meets your needs and to understand the processes involved in water purification before making a purchase.
