What are the best water filters – guide

Instead of one “universal winner,” we show when which solution is reasonably “the best.” This makes it easier to answer the questions: whatthe best water filter for your kitchen and what are the best under-sink water filters for a family with a specific consumption.

Under sink (kitchen)

• Reverse osmosis (RO) – the deepest filtration of tap water; combines pre-filters, a membrane, and a mineralizer. Often it is the best under-sink water filtersink for those who expect flavor and repeatability.
• Ultrafiltration (UF 0.01 µm) – great where high clarity is important without discharge to the sewage system (e.g. WODARO FLOWLINE – compact 4-stage UF).
• Linear flow systems – minimal installation when space is limited and the water is organoleptically acceptable.

Bathroom and the whole house

• Water softener – comfort and protection of fixtures in hard water; selection based on the number of people and hardness.
• Shower filter – quick improvement of skin and hair comfort (e.g. SoftSkin, Vitarain).
• Inline filters – mechanical and carbon as the firststage for the whole house.

It’s worth remembering: “what type of water filter is the best?” depends on the water source, installation location, and taste preferences — this is the triad from which we start the selection.

Which company's water filters are the best?

The questions “which filter brand is the best?” and “which company's filter is the best?” come up most often. Our answer: it depends on the application and the logistics of spare parts. We recommend brands that combine consistency in quality,service availability and transparent specifications.

• WODARO – one of the largest manufacturers and distributors of water filters in Poland: RO/UF systems, under-sink kits, treatment stations, accessories, instructions PL.
• AQUAVITA – cartridges, reverse osmosis, and linear solutions, valued for quality
• OTOWODA – cartridges at good prices (stable parameters and wide availability).
• BIOCERA – mineralization and ionizing cartridges (ORP), for a specific water profile.
• KLARWOD /USTM – a wide range and a strong position in the Polish market.

The most popular water filter in 2025

Growing popularity: under-sink systems with mineralization and compact UF. In many homes, the "most popular water filter" today is RO with a linear mineralizer; in apartments with limited space – UF 0.01 µm.

Filter selection: 5 control questions

Before you decide, please briefly answer five questions — this is how our advisors work during conversations:

1. What is your water source (mains/well) and its parameters (e.g., hardness, iron)? [preferably provide test results]
2. How many people use water on a daily basis and what is the average consumption?
3. What is your installation location (under-sink cabinet, boiler room) and access to drainage?
4. What effect are you expecting (taste, lack of hardness, comfort for skin/hair)?
5. What budget do you foresee "to start" and for annual refills?

After gathering the data, we will suggest 1-2 options — this makes it easier to decide what the best water filter is for your situation.
