What is osmosis?

Osmosis is a natural phenomenon in which water molecules move through a semipermeable membrane from a solution of lower concentration to a solution of higher concentration. In practice, this means that water seeks to equalize concentrations on both sides of the membrane. Microscopic pores allow only water molecules to pass through, while larger impurities are retained. Water osmosis is a fundamental process in nature, occurringamong others. in plant and animal cells. Osmosis is the key to understanding how reverse osmosis works.

How does reverse osmosis work and what is it?

What is reverse osmosis? Reverse osmosis filters are advanced devices that operate by allowing water to pass through a special osmotic membrane. This membrane is a key element of water are allowed to pass through freely. This process results in clean water, free from harmful pollutants and organic substances.

Water under high pressure is passed through the membrane, causing contaminants such as heavy metals, bacteria, viruses, and other harmful substances to be retained. Molecules water passes through the membrane, while impurities are drained away. Thanks to this process, reverse osmosis filters provide access to crystal clear water that is completely safe for drinking and cooking.

Reverse osmosis - why is it worth buying?

Have you ever wondered how to improve the quality of drinking water in your home? Water from the reverse osmosis filter not only offers better taste but also a healthier choice for you and your family. With reverse osmosis, you can forget about buying bottled water and enjoy crystal-clear water straight from the tap. Want to know more details? Read on!

RO Filter - benefits of drinking water treatment

What does reverse osmosis remove? This is a question many people ask themselves. RO filters effectively eliminate.

  • Heavy metals such as lead, mercury, or cadmium.

  • Organic substances and pesticides.

  • Harmful microbiological contaminants

  • Unpleasant taste and smell of water caused by the presence of chlorine.

  • Compounds responsible for water hardness, which protects household appliances.

  • Bacteria, viruses, and fungi

  • Microplastics and hormones

Additionally, using RO filters contributes to environmental protection by eliminating the need to buy bottled water. This is not only a benefit for health but also for the planet :)

Reverse osmosis filters - cons

Every solution has its drawbacks. In the case of reverse osmosis, one of the downsides is that it also removes all mineral salts, which can lead to its sterility. Therefore, if you plan to use the system for drinking water, it's worth investing in systems with a mineralizer that enriches the water with essential minerals. Reverse osmosis without a mineralizer can be ideal for technical purposes, but for health, it's important to ensure proper mineralization.

Reverse osmosis - types of RO systems

Are you wondering what osmosis system will reverse be the best for you? Reverse osmosis systems are available in various versions, tailored to the individual needs of users. Below we present the most popular types.

Reverse osmosis filters with a tank

This is the traditional type of reverse osmosis filters, where the purified, clean water is stored in a tank. After using the water from the tank, you need to wait until it is refilled. This type of reverse osmosis filter usually has a higher water rejection rate (1l to 4-8l). The system operates efficiently at pressures from 3 bars, so if you have lower pressure, installing a water pressure booster pump is mandatory; with proper pressure, it is optimal (at high pressure, the rejection decreases). If you value proven solutions, this is the option for you!

Reverse osmosis filter without tank

This is a modern reverse osmosis filter, where water is filtered continuously without the need for storage. This means you don't have to wait for the tank to refill after high water usage. The cartridges in such systems are replaced quickly. They are usually equipped with a pump, which allows for efficient operation even at very low pressure. If you value convenience and modernity, this solution is perfect for you!

Reverse osmosis systems with mineralization

These are systems where a mineralizer has been added to the reverse osmosis system. Thanks to this, the quality of drinking water is even better, and the water is enriched with essential minerals. An ideal solution for health-conscious individuals. Water from such systems can be dispensed using a two-way tap – on one side completely pure water after mineralization, on the other side crystal clear osmotic water without minerals.

Osmosis filter without mineralization

If you are looking for a solution mainly for technical purposes, such as powering a kettle or an iron, osmosis filters without a mineralizer will be suitable. Although this water can be consumed, it is advisable to ensure the intake of minerals from your diet. Water from these systems is crystal clear osmotic water.

Osmotic filter with ionization

These are advanced systems that, in addition to mineralization, also ionize the water, raising its pH and adding antioxidant properties. Osmotic filters with ionizers provide water with health-promoting properties, supporting your health on a daily basis.

Reverse osmosis membrane

The most important filter for reverse osmosis - the heart of every osmosis filter. The semi-permeable membrane, also known as the osmotic membrane, is responsible for retaining even the smallest impurities. Thanks to it, water is purified at the molecular level (99.99% of impurities).

➡️ Learn more: Osmotic membrane

High-pressure pump of the reverse osmosis system

When the water pressure in the installation is too low (usually below 3 bar), the pump raises it to an optimal level. This increases the efficiency of the system, reduces water rejection, and ensures that the device operates reliably. It is not always necessary, but it is a proven way to increase efficiency. In modern tankless systems, this is standard.

➡️ See pumps: Water pumps

Pressure tank

This is where the water filtered in traditional systems goes. Thanks to the air cushion, it maintains the appropriate pressure, usually around 0.7 psi. It provides a constant supply of clean water without the need for continuous filtering.

➡️ Check tanks: Pressure tanks for osmosis

Osmosis filters

These are filter cartridges that eliminate various types of contaminants. They include.

  • Foam – removes larger solid particles.

  • Coal block – removes chlorine and organic compounds.

  • Linear carbon – improves water quality and taste.

  • Linear mineralizer – enriches water with minerals.

  • Ionizers and structurers – give water health-promoting properties.

➡️ Learn more: Reverse osmosis filters

Housings and enclosures

Are responsible for the tightness and safety of the system. Filters with reverse osmosis in traditional systems use housings that withstand pressures up to 6 bars. A solid casing guarantees long-lasting and trouble-free operation.

Reverse osmosis filter for home - frequently asked questions

Do you have questions about reverse osmosis filters? Below you will find answers to frequently asked questions.

Is it worth buying a reverse osmosis filter?

Definitely yes! A reverse osmosis filter is an effective way to eliminate harmful chemicals from water. With it, you gain access to clean and healthy water, eliminating the need to buy bottled water. By investing in a reverse osmosis system, you take care of your health and your family's health, while also contributing to environmental protection. By eliminating bottles, your purchase will quickly pay off.

How often should you replace filters in reverse osmosis?

In every reverse osmosis system, the filter replacement schedule may vary slightly. Generally, it is assumed that:

  • Pre-filters should be replaced every 6 months.

  • Osmotic membrane – every 2-5 years, depending on water quality and usage intensity.

  • Inline filters (e.g., mineralizers) – every 12/24 months.

Regular replacement ensures the system's effectiveness and the highest water quality.

What instead of reverse osmosis?

If you are looking for an alternative, you might consider systems with a capillary membrane. This is a cheaper option that also effectively removes impurities, although not as fine as in the case of osmosis. The choice depends on your needs and expectations regarding water quality.

What is water rejection in reverse osmosis?

Water rejection is the part of the water that during the filtration process removes harmful impurities and chemical substances for drainage. It is essential to ensure the highest purity of the obtained water. Modern systems minimize waste while also maintaining filtration efficiency and water savings.

Osmosis - summary and conclusions
