Как профессиональный завод по производству очистителей воды обеспечивает стабильность и высокое качество продукции
29 октября 2025 г.With growing awareness of health and safe drinking water, a whole house water filtration system has become a must-have for modern households.
This system combines multiple filtration devices, including: pre-filter, central water filter, water softener, RO (reverse osmosis) water purifier, and point-of-use drinking water appliances.
Each device performs a specific function, ensuring comprehensive, multi-level water purification for your home and keeping every drop of water safe and healthy.
Pre-Filter — The First Line of Defense for Your Home Water
The pre-filter is installed at the main water inlet, providing coarse filtration for the entire household. It mainly removes sand, rust, and large particles.
Common types include:
- Copper Pre-Filter
- Stainless steel mesh with 40μm precision
- No replacement needed, only regular backwashing
- Durable and low-maintenance
- PP Cotton Filter
- Higher filtration precision (5μm)
- Requires regular filter replacement
- Provides better water quality for households with higher standards
💡 Installation Tips: Avoid direct sunlight and ensure insulation in winter to prevent freezing and potential cracking.
Central Water Filter — Removing Odors and Heavy Metals
Installed after the pre-filter, the central water filter contains activated carbon and KDF media, effectively removing chlorine, odors, and heavy metals.
It is usually fully automated, requiring only a power supply. Filter replacement depends on water quality and usage, generally every 1–3 years.
Neglecting filter replacement may reduce effectiveness and even cause secondary contamination.
Water Softener — Enhancing Water Quality for Everyday Life
Water from the central filter splits into two lines, one going to the water softener.
Using ion exchange technology, it removes calcium and magnesium ions, reducing water hardness. This protects household appliances such as water heaters and washing machines.
🧂 Maintenance Tips:
- Keep the salt tank filled with soft water salt
- Replace the softening resin every 3–5 years
RO (Reverse Osmosis) Water Purifier — Providing Safe Drinking Water
The other line goes to the RO water purifier, which has a filtration precision of 0,0001 мкм, effectively removing bacteria, viruses, and heavy metals, leaving only water molecules.
RO systems typically include:
- Pre-filters (PP cotton or activated carbon): replace every 3–6 months
- RO membrane: replace every 1–2 years
- Post-activated carbon: replace every 1 year
This ensures high-purity drinking water, suitable for cooking and daily consumption.
Point-of-Use Drinking Appliances — The Final Step for Healthy Water
RO water can be delivered via food-grade PE pipes to wall-mounted or built-in drinking water dispensers.
These dispensers require no additional filter and provide various water temperatures (hot, warm, or cold), meeting the diverse needs of your household.
✅ How to Choose a High-Quality Whole House Water Filtration System
Assess Your Needs: Consider family size, water quality, and water usage.
Check Materials and Brands: Choose food-grade materials and reputable brands to ensure safe and stable performance.
Installation & After-Sales Service: Opt for manufacturers providing installation guidance and filter replacement services.
Energy & Maintenance Costs: Evaluate energy consumption, ease of maintenance, and replacement costs.
Conclusion
A high-quality whole house water filtration system not only ensures safe drinking water but also improves overall quality of life.
Professional manufacturers recommend customized solutions based on water quality and household needs, making sure every drop of water in your home is pure, safe, and healthy.
