What are Water Purifier Filters?

3

Water purifier filters are the most critical components that remove harmful substances, limescale, bacteria, and sediments from water, ensuring clean and healthy drinking water. A water purifier filter consists of layers that subject water to different purification processes at each stage and must be replaced regularly to maintain the system’s efficiency. These filters work in harmony, purifying water from the moment it enters the system until it is dispensed.

The Importance of Filter Replacement in Water Purifiers

Over time, water purifier filters can become clogged or lose their effectiveness due to sediment, chlorine, heavy metals, and microorganisms present in the water. If the filters are not replaced at recommended intervals, the performance of the water purifier system is significantly reduced. This not only compromises water quality but also shortens the lifespan of the device.

A water purifier without timely filter replacement may allow harmful substances to pass through, posing a threat to your health. Therefore, filters should be checked periodically and replaced depending on usage intensity. To maintain your water purifier’s performance and ensure uninterrupted access to healthy water, you can benefit from the high-quality filter replacement services offered by Sulax water purification systems.

What Are Water Purifier Filters?

Water purifier filters are the essential components used to remove contaminants from water. Thanks to the water purifier filter, water becomes safe for drinking or household use. The main types of filters include the 5-micron filter, granular activated carbon filter, CTO carbon block filter, membrane filter, and mineral filter. Each of these filters has a unique function within the system, ensuring multi-stage purification of the water.

5-Micron Filter

The 5-micron filter is the first stage in a water purifier and is also called the sediment filter. This filter traps visible physical contaminants such as sediment, rust, sludge, and sand. Thanks to its pores measuring 5 microns, large particles cannot pass through, effectively protecting the other filters in the system.

The 5-micron sediment filter used in water purifiers should be replaced every 3–6 months. If not replaced in time, it can become clogged, disrupting the entire purification process.

CTO Carbon Block Filter

The CTO carbon block filter is a type of water purifier filter made from compressed activated carbon material. It is especially effective in removing unpleasant odors, tastes, and chemical contaminants such as chlorine. The CTO carbon block filter provides more homogeneous purification, directly influencing the quality of the water. It is indispensable among water purifier filters and should be replaced approximately every 6 months.

Granular Activated Carbon Filter

The granular activated carbon filter comes before the CTO carbon block filter. The granulated activated carbon particles absorb harmful substances such as chlorine, detergent residues, pesticides, and industrial chemicals upon contact with water.

As a water purifier filter, granular activated carbon is highly effective in removing bad tastes and odors. It is especially ideal for municipal tap water.

Membrane Filter

The membrane filter is the most important water purifier filter used in reverse osmosis (RO) systems. Its semi-permeable structure allows only water molecules to pass through while retaining harmful substances such as heavy metals, arsenic, nitrates, viruses, and bacteria.

Among all water purifier filters, this stage provides the finest level of purification and plays a key role in producing clean drinking water. Its average lifespan is 1–2 years, depending on water hardness.

Carbon and Mineral Filters

The carbon filter and mineral filter are two essential components that play complementary roles in water purification systems. Carbon filters, available in both granular and block form, remove chlorine, unpleasant odors, taste impurities, and organic contaminants, providing chemical purification. Like all other filters, carbon filters eventually become saturated and should be replaced once a year.

The mineral filter functions at the final stage of the purification process. After passing through the membrane filter, water is stripped of all harmful substances and becomes pure, but this also removes its natural mineral balance. At this point, the mineral filter adds beneficial minerals such as calcium and magnesium back into the water. As a result, the water becomes tastier and healthier to drink. Among water purifier filters, mineral filters have a special place and should be replaced once a year.
