How to choose a water filter suited to your needs

EXPERT GUIDE WITH DIMM

The quality of water you consume is crucial for your health, the proper functioning of your domestic installations and environmental preservation. Today, faced with increasing pollution and climate variations, it is essential to filter your water to eliminate contaminants, particles, microbiological agents and limescale.

However, choosing the right water filter can seem complex with the multitude of options available. This comprehensive guide helps you understand your real needs, analyze your water quality, and select the most effective treatment solution. Thanks to the complete and innovative range offered by DIMM, a recognized player in Belgium, you will have reliable and high-performance tools for pure water every day.

Understanding your water quality: the essential first step

1.1 Having your water analyzed: which parameters to check precisely?

This should ideally be done by a certified laboratory or through a professional assessment offered by DIMM.

The essential parameters to check are:

• Hardness: The level of calcium and magnesium, responsible for limescale that clogs pipes and damages household appliances.
• Nitrates: Residues from agricultural fertilizers that can cause long-term health problems, especially in infants.

• Heavy metals: Lead, arsenic, mercury, sometimes present in old networks or polluted areas, with high toxicological risks.
• Pesticides and persistent organic pollutants: These chemical substances infiltrate aquifers and can affect health.
• Turbidity: Presence of suspended particles, sediments or organic matter, which can harbor microorganisms and interfere with disinfection.
• pH, taste and odor: To detect chemical imbalances or presence of chlorine

1.2 Identifying the source and specific problems with your water

The nature of the water source strongly determines the risks and treatment to apply:

• Public network water: generally treated, but may contain chlorine, pharmaceutical residues, microplastics and other residual contaminants.
• Well, borehole or groundwater: likely to be contaminated by bacteria, nitrates, organic matter or heavy metals.
• Rainwater: increased risk of atmospheric particles, dust, organic matter and urban pollutants.
• Surface water (rivers, lakes): very sensitive to turbidity and microbiological contamination.

Different types of water filters at DIMM: characteristics and functions

2.1 Sediment filters - the essential first barrier

Pre-filtering with a Big Blue 20'' filter housing equipped with a 5-micron sediment cartridge is essential to retain sand, mud, clay, microplastics and other visible solid particles.

This protects downstream installations (reverse osmosis units, softeners) by limiting fouling and extends the lifespan of finer filters.

2.2 Activated carbon filters - to improve taste and reduce chemical pollutants

Activated carbon cartridges effectively eliminate:

• Chlorine and its by-products responsible for unpleasant odors and tastes
• Certain pesticides, herbicides, solvents and volatile organic compounds (VOCs)
• Certain molecules responsible for endocrine disruption

Activated carbon acts through adsorption, retaining these substances on its surface, which significantly improves the sensory quality of water.

2.3 Reverse osmosis - ultra-fine filtration for maximum purity

The A2O Pure system uses an extremely fine semi-permeable membrane (0.0001 micron), capable of eliminating up to 99% of contaminants:

• Microscopic microplastics
• Heavy metals (lead, arsenic, mercury)
• Nitrates, pesticides, PFAS (perfluoroalkylated substances)
• Bacteria, viruses, protozoa

This technology guarantees perfectly pure water, ideal for health-conscious households, at-risk individuals, or areas with confirmed contamination.

Note: reverse osmosis generates water discharge; DIMM offers optimized systems to reduce this waste.

2.4 UV sterilization - disinfection without chemicals

Installing a UV lamp effectively destroys pathogenic microorganisms (bacteria, viruses, parasites) in seconds, without adding chemical products or altering taste.

Ideal for securing well water or potentially contaminated water, UV sterilization perfectly complements filtration systems.

2.5 Water softeners - lasting protection against limescale

DIMM water softeners allow you to lower water hardness by exchanging calcium and magnesium for sodium, thus preventing limescale deposits.

This protects pipes, water heaters, dishwashers and reduces energy consumption related to scale buildup.

Essential criteria for choosing the filter suited to your needs

3.1 Nature of pollutants and priority needs

Each water is unique. If you mainly detect:

• Particles: prioritize Big Blue 20'' sediment filter
• Tastes or odors: add an activated carbon filter
• Major chemical contaminants: opt for A2O Pure reverse osmosis
• Microbiological risk: choose UV sterilization

3.2 Volume and frequency of use

• For standard domestic use, DIMM filters are compact and efficient.
• For agricultural or industrial use, DIMM offers equipment sized and modular according to flow and water quality.

3.3 Ease of installation and maintenance

DIMM products are designed for simple installation, often in a few hours, with technical support available.

Maintenance is facilitated by easily replaceable cartridges and maintenance packages offered.

3.4 Budget and value for money

DIMM offers a complete range, from economical filters to high-end systems, guaranteeing optimal water quality while controlling overall costs.

3.5 Certifications and standards

All DIMM filters comply with strict European standards (CE, ACS), guaranteeing safety, effectiveness and durability.

Maintenance and monitoring: the key to high-performance filtration over time

• Replace cartridges according to recommendations, generally between 6 and 12 months.
• Regularly check UV sterilizer operation and clean the lamp if needed.
• Perform a new water analysis each year to adjust your system.
• Take advantage of DIMM after-sales service for personalized and fast follow-up.
