Filtry do wody pod zlew - CzystyStyl

Clean and healthy water straight from the tap

Looking for an effective way to enjoy clean drinking water straight from the tap? At CzystyStyl, we offer professional under-sink kitchen water filters : from reverse osmosis (RO) systems that remove bacteria and viruses to carbon filters that improve taste and odor. We offer drinking water filters from market leaders such as Philips , Ecosoft , Aquaphor , Midea , and ViO Filters . All our kits are complete, ready for self-assembly, and covered by a warranty. Choose health and convenience without leaving home.

Why is it worth installing an under-sink filter?

The decision to install an under-sink filter is an investment that pays off quickly – both financially and in terms of health. Although tap water meets sanitary standards, it often leaves much to be desired in terms of taste, odor, and hardness.

Here are the key benefits of having your own filtration system:

  • Health and safety: Remove harmful substances from water, including microplastics, pesticides, pipe rust, and microorganisms.
  • Better taste of food and drinks: Coffee, tea and homemade soups prepared with filtered water release their full aroma.
  • Protection of household appliances: Soft water (scale-free) extends the life of kettles, coffee machines and irons.
  • Ecology and Zero Waste lifestyle: By giving up bottled water, you reduce the amount of plastic thrown into the environment by hundreds of kilograms per year.

Types of filters in our offer: Reverse osmosis and nanofiltration

At CzystyStyl, we focus on proven and uncompromising technologies. Reverse osmosis (RO) is the most popular choice among our customers. It's currently the most accurate and safest filtration method available for households.

In addition to classic models, our offer also includes modern tankless reverse osmosis filters (direct flow). These produce water continuously, without the need for storage. This is an ideal solution for smaller kitchens – the device is compact and takes up half the cabinet space of traditional units.

New generation RO filters

Regardless of the model chosen, the reverse osmosis membrane provides an effective barrier against 99% of all contaminants . It removes from water:

  • Microplastics and mechanical deposits,
  • Heavy metals (lead, mercury, cadmium),
  • Bacteria and viruses ,
  • Chlorine , pesticides and scale.

By choosing osmosis, you can be sure that the water you drink is crystal clear and completely safe even for small children.

For those looking for simpler solutions, we offer classic under-sink systems that operate as sorption filters (based on nanofiltration or ultrafiltration). These are compact and effectively improve the taste and odor of water by removing chlorine and basic sediments.

However, it's worth remembering that these systems have their limitations and are not as effective as reverse osmosis . Sorption filters:

  • They do not soften water – if you have a problem with limescale in your kettle, this filter will not solve it.
  • They do not remove heavy metals or most microorganisms (viruses and bacteria). We recommend this solution only where tap water is already safe, soft, and of good quality, and the goal is merely to "cosmetic" improve its taste.

Water mineralization – health straight from nature

A common myth is that filtered water is "sterile." At CzystyStyl, we ensure that water is not only clean but also nutritious. Most of our under-sink filter sets are equipped with special mineralizing cartridges.

In the final stage of filtration, the water flows through a natural dolomite deposit, thanks to which it is once again enriched with elements essential for health:

  • Magnesium – supports the nervous system and heart function.
  • Calcium – crucial for healthy bones and teeth. This provides water with parameters similar to high-quality spring water, available at any time from your own tap.

Importantly, our systems are flexible. Even if you initially choose a basic model without a mineralizer, you can purchase one separately and install it at any time . This gives you complete freedom in configuring your filter and the ability to expand it in the future.

Saving money – is it worth it?

An under-sink filter is a one-time expense that generates ongoing savings. A liter of filtered water costs just a few cents, including the cost of replacing the cartridges and water consumption.

A simple calculation: a family of four spends an average of 2,000 to 5,000 PLN per year on bottled water. The operating cost of a filter (replacement of cartridges) is only a fraction of this amount. An investment in an under-sink system typically pays for itself within the first year of use.

Simple installation and convenient operation

Worried about complicated installation? No need. The kits we offer are designed for simple and intuitive installation. The box includes all the necessary connectors, hoses, and a modern spout.

Compact reverse osmosis filter mounted in a cabinet under the sink

Under-sink filters take up minimal space and easily fit in a standard kitchen cabinet, even next to waste bins. Replacing the cartridges is quick and doesn't require calling a professional – just do it every six months to enjoy perfect water quality for years to come.

Prefer a ready-made solution? At CzystyStyl, you can order professional installation and periodic cartridge replacement . Our service technicians will ensure proper connection and maintenance of the device, saving you time and ensuring the system operates flawlessly.

Frequently asked questions

  • It depends on the quality of your water.Reverse osmosis (RO)This is the most effective choice for completely removing limescale (water hardness), viruses, and microplastics. It's ideal for kettles and coffee machines.Flow filters (carbon)They're great if you have soft water and just want to improve its taste and remove chlorine. However, remember that a flow-through filter won't protect your appliances from limescale as effectively as reverse osmosis.

  • To choose the perfect system for your kitchen, check out these 6 features:

    1. Membrane efficiency:Marked in GPD. The higher the GPD (e.g., 400-600 GPD), the faster the filter produces clean water.
    2. Required pressure:Check your system's pressure. Standard filters require a minimum of 2.8 bar. If yours is lower, be sure to choose a model with an electric pump.
    3. Water tank:Decide whether you prefer a traditional tank system (water supply) or a modern tankless system (direct-flow), which takes up less space and produces fresh water continuously.
    4. Dimensions:Measure the available space in the cabinet, including the drain trap and waste bin.
    5. Mineralization:Make sure the filter has a mineralizing cartridge that restores valuable minerals to the water and improves its taste.
    6. Additional amenities:It is worth paying attention to cartridge replacement indicators (reminders), smart taps with a water quality display, or a "slim" design that allows for installation in unusual places (e.g. under a cabinet).

  • Standard reverse osmosis systems with a tank operate using mains water pressure (minimum 2.8-3 bar required). Electrical connection is only necessary in two cases: if you choose a modern tankless (direct-flow) filter with a pump, or if you have very low water pressure in your home and need to use a booster pump.

  • Replacement is simple and doesn't require a service call. The schedule is as follows:

    • Pre-inserts (foam, carbon):every 3-6 months.
    • Mineralizer / Final Carbon Insert:every 6-12 months.
    • Osmotic membrane:approximately every 18-24 months.
      Many of our filters have a "Twist & Click" system or quick-connect fittings, so replacing the cartridge takes literally 2 minutes.

  • Less than you think. Modern filters are designed to fit in a standard kitchen cabinet (60 cm), even next to the trash can.

    • Systems with tank:They need a rectangular space of approximately 30x40 cm.
    • Tankless systems (Direct Flow):They are very narrow (approx. 10-15 cm) and take up as much space as an office binder.
    • Slim models:Some of the latest systems are so flat they can be mountedunder furniture (in the kitchen plinth)or lay it flat on the bottom of the cabinet. This solution saves you virtually no valuable space inside the cabinet.

  • Yes,the assembly is fully reversible. It only requires connecting to the cold water valve (T-piece included) and possibly drilling a hole for the spout in the countertop (or replacing the tap with a three-way one).avoid drilling a hole in the countertop, you can buy from uskitchen tap with filter connection(three-way faucet). You install it in place of your existing faucet. When you move out, simply take the filter and your faucet with you and replace it with your owner's old faucet. This way, you won't leave any permanent marks in your kitchen.
