Types of water filters

The market offers a wide range of solutions, so it is worth matching filtration to the actual water problem and the installation location. Below you will find an organized overview of the most popular types.

Under-sink water filters

These are advanced systems installed directly under the kitchen sink. They are not visible at first glance, while significantly affecting the quality of water used for drinking and cooking.

• Reverse osmosis filter – removes nearly all contaminants from water, including bacteria, viruses, and heavy metals. In systems with an optional mineralizer, the water can be enriched with minerals.
• Single-stage inline filters – focus on reducing selected contaminants, such as chlorine, organic compounds, or heavy metals, improving the taste and smell of water.
• Multi-stage systems – combine mechanical, carbon, ion-exchange, and membrane filtration for high efficiency.

Faucet water filters

These are compact devices installed directly on the faucet spout. They work well where quick installation and convenient use matter, without major interference with the plumbing system.

• Carbon filters help remove chlorine and organic compounds and improve the taste and smell of water.
• Filtration takes place in real time, without the need to store water.
• Easy installation and removal make them a good solution also for rented apartments.

Inline and in-line housing filters

Inline filters are installed directly on water pipes. This is an economical solution with replaceable filter cartridges that can be matched to the type of contaminants.

• In-line housing filters are available in various sizes, including standard and BigBlue.
• Depending on the cartridge, the system may remove mechanical impurities, chlorine, organic compounds, iron, or manganese.
• Simple operation and easy cartridge replacement help keep operating costs low.

Water softeners, iron removal filters, and whole-house systems

If the problem concerns the entire plumbing system, it is worth considering devices designed for comprehensive water treatment throughout the building.

• Water softeners work on the principle of ion exchange, where sodium ions replace calcium and magnesium ions responsible for water hardness.
• Manganese removal and iron removal filters are especially useful with a private water source, e.g. from a well, where there is an elevated concentration of iron and manganese.
• Multifunction whole-house filters use special resins and help remove a very wide spectrum of contaminants.

Bathroom filters

Water quality also matters during bathing and washing. Bathroom filters are installed, among other places, at the shower, bathtub, or washing machine.

• Reduction of chlorine may reduce discomfort related to skin irritation and dry hair.
• Reduction of deposits helps keep fittings and shower cabins in better condition.
• Improved condition of skin and hair is one of the most frequently indicated practical benefits.

Aquarium filters

In aquaristics, clean water is of fundamental importance for the health of fish and plants. Aquarium filters help remove fine particles of mechanical impurities, stabilize water parameters such as pH, hardness, and cleanliness, and at the same time are easy to use.

Filter cartridges – the heart of every system

The effectiveness of filtration depends not only on the housing or type of device, but also on a properly selected cartridge. This category includes cartridges in various sizes, including 10 inch, 20 inch, and BigBlue.

Remember: regular cartridge replacement ensures optimal filtration efficiency and helps maintain the long lifespan of the entire system.

How to choose a water filter?

Before buying, it is worth answering a few simple questions. This makes it easier to choose a solution that will be effective and convenient in everyday use.

• Where do you want to filter the water? For drinking and cooking, under-sink or faucet systems are usually chosen, while for protecting the plumbing system and appliances – whole-house solutions.
• What problem do you want to solve? One filter will work well for chlorine and poor taste, another for hard water, and yet another for iron and manganese.
• Do you use municipal water or a well? A private water source often requires more advanced treatment.
• How important is ease of installation? Faucet filters and some inline systems are easier to install than extensive central systems.
• Do you want to reduce the cost of buying bottled water? In that case, under-sink drinking water filters work especially well.
