5-Stage Compact Domestic UF System

n

The 5-Stage Compact Domestic UF System from Puritech is a user-friendly ultrafiltration setup designed for reliable household water filtration. It delivers clean, safe water using a five-stage filtration process, ideal for drinking, cooking, and everyday domestic use. Because it’s chemical-free and operates without power (UF only), it’s especially suited to homes looking for simplicity and effectiveness.

Filter Stages & Water Treatment

n

This system includes five filter stages to improve water quality:

n
n

n
1. PP (5 Micron Sediment Pre-Filter) – removes visible particles such as sand, rust, and dirt.

n

2. GAC (Granular Activated Carbon) – absorbs chlorine, odors, and organics to improve taste.

n

3. CTO (Chlorine, Taste & Odor Carbon Block) – further refines water, removing residual chemicals and improving clarity.

n

4. UF Membrane – a hollow fiber ultrafiltration membrane with ~0.01 µm pores; removes bacteria, suspended solids, and many pathogens.

n

5. T33 Polishing Carbon Filter – final stage to polish taste and odor before water reaches the tap.

Benefits & Applications

n

n
• Clean & Safe Water: Removes bacteria, suspended solids, and improves taste.

n

• Low Maintenance: No power, simpler parts, and easy filter replacement.

n

• Improves Health and Safety: Good for households with municipal water that may still contain impurities.

n

• Domestic Use: Best suited for homes, small cottages, or places where plug-in power is limited.

n

• Filter Longevity: Since there’s no RO stage, membrane lifespan tends to be good in moderate use.

Usage Notes & Water Analysis

n

n
• This system is designed for municipal water or well water that’s already treated or of reasonable quality.

n

• If water has high sediment, turbidity, or chemical load, use a proper pre-filter or improved source to prevent frequent clogging of pre-filters and UF membrane.

n

• Because there is no RO stage, dissolved salts won’t be removed—if your water requires salt reduction, consider an RO system instead.

Installation & Maintenance Tips

n

n
• Mount the unit where it’s easy to access for filter changes (every few months, depending on water quality).

n

• Flush pre-filters regularly.

n

• Ensure input water pressure is within the specified range (0.1-0.4 MPa), because too low or too high pressure may reduce performance or damage filters.

n

• Maintain the system dry when not in use for extended periods to avoid the growth of algae or biofilm.
