A 5 micron filter bag has pores sized to
capture particles as small as 5 microns (5 micrometers). One micron equals
one-millionth of a meter, so 5 microns is about 1/14th the width of a human
hair. This makes 5 micron filters effective at removing fine sediment and rust
particles, while maintaining good flow rates.

Here's a helpful comparison:

• Human hair: 70-100 microns
• Fine dust and silt: 1-10 microns
• Large bacteria: 2-5 microns
• Red blood cells: 6-8 microns
• Pollen: 10-1000 microns
• White blood cells: 25 microns A 5 micron filter captures particles visible under a microscope but invisible to the naked eye.

5 micron filter socks effectively remove:

• Medium to fine sediment and silt
• Rust and scale particles
• Fine dirt and debris
• Sand particles
• Some algae
• Suspended solids in liquids
• Industrial particulates and contaminants

Nominal 5 micron rating means the filter
removes up to 95% of particles at 5 microns in size. Absolute 5
micron rating means 99.9% or more of 5-micron particles are removed. Most bag
filters use nominal ratings, so some particles smaller than 5 microns may pass
through, especially under varying flow conditions.

Yes, 5 micron filter bags are excellent for
sediment removal. They effectively capture fine sediment, silt, sand, and
suspended particles that cause water cloudiness. They're particularly effective
for general sediment control without excessive flow restriction.

5 micron filter socks do not remove chlorine, chemicals, or dissolved contaminants that cause taste and odor issues. They are purely mechanical filters for particulate removal. For taste and odour
improvement, you need activated carbon filters or specialised chemical removal
systems in addition to sediment filtration.

5 micron filter socks provide a good balance between filtration and flow rate. While they create more restriction than
larger micron filters (10-50 micron), they maintain much better flow rates than
finer filters (1 micron). Most systems can accommodate 5 micron bags without
significant pressure issues.

5 micron filter bags clog faster than 10-50
micron filters due to their smaller pore size, but much slower than 1 micron filters. Clogging rate depends on water quality - in moderately contaminated water, they typically last 2-4 times longer than 1 micron bags while providing significantly better filtration than 10+ micron options.

Pre-filtration is recommended when dealing with heavily contaminated water or high sediment loads. Use 25-50 micron
pre-filters to remove larger particles first, extending the life of your 5 micron bags and maintaining better flow rates. This staged approach is more cost-effective for challenging water conditions.

Replace when you notice:

• Decreased water flow or pressure
• Increased pressure differential across the filter (max dp 1 bar)
• Return of sediment or cloudiness in filtered water
• Visible contamination or discoloration of the bag
• Foul odors (indicating bacterial growth)
• Physical damage to the bag material
• Reaching recommended service interval – every 3 months

Change filter bags when differential pressure reaches 1 bar or every 3 months.

Some 5 micron filter bags made from materials like nylon mesh can be cleaned and reused. However:

• Cleaning effectiveness decreases with each use
• Filtration efficiency may be reduced after cleaning
• Felt bags are typically single-use only
• Cost of cleaning versus replacement should be considered Always follow guidelines for your specific bag type.

• Weekly: Check system pressure and flow rates
• Monthly: Visual inspection of housing and connections
• Every 3 months: Replace filter bags (or as needed based on pressure)
• During each change: Clean filter housing interior
• Annually: Inspect housing seals and system components
• Ongoing: Maintain spare bags and monitor water quality

Choose bag filters for:

• High flow rate requirements
• Cost-effective operation
• Easy maintenance and replacement

5 micron filter socks can improve drinking water quality by removing sediment and fine particles. However, they should be part of a comprehensive treatment system that may include:

• Pre-filtration for larger particles
• Carbon filtration for chlorine and taste
• UV or chemical disinfection for complete microbial safety
• Post-filtration for final polishing

All Polypropylene, Nylon and Polyester filter bags supplied by CLARIBag are food grade.

Yes, if your current system uses standard
4" or 7" diameter bag filters, you can typically retrofit with 5 micron bags. Consider:

• Current housing compatibility
• System pressure and pump capacity
• Expected increase in pressure drop
• More frequent maintenance requirements
• Possible need for pre-filtration Consult with your system manufacturer if unsure about compatibility.

Consider:

• Filter costs: Moderate, more than coarse filters but less than fine filters
• Replacement frequency
• Labor: Minimal, simple bag replacement
• Energy costs: Low pressure drop impact
• System protection: Reduced downstream maintenance
• Performance value: Good balance of quality and economy

Possible causes:

• Filter is already loaded and needs replacement
• Particles smaller than 5 microns causing turbidity
• Bypass around filter due to poor sealing
• Wrong filter type for your specific particles
• System flow rate too high for effective filtration
• Need for finer filtration (1 micron)
• Dissolved contaminants requiring different treatment

Immediate actions:

1. Stop system operation
2. Inspect installation for proper seating
