Water sustains life, yet invisible contaminants may lurk within. Selecting an appropriate filtration system is crucial for safeguarding household water quality. Among various options, Rusco filters stand out for their exceptional performance. However, understanding key specifications—particularly micron and mesh ratings—is essential before purchase.
Key Considerations for Rusco Filter Selection
Before integrating a Rusco filter into your residential water system, evaluate these critical factors to ensure optimal performance:
1. Inlet/Outlet Dimensions:
Verify compatibility with existing plumbing. Mismatched sizes may complicate installation or impair functionality.
2. Flow Rate (GPM):
Assess household water consumption in gallons per minute. Select a filter that maintains adequate flow without restricting usage.
3. Temperature Application:
Filters have specific material requirements for hot or cold water systems. Choosing appropriately extends service life and maintains efficiency.
4. Installation Position:
System placement determines structural needs. Certain locations may require L-shaped or combination-body filters rather than standard T-shaped units.
5. Filtration Fineness:
The micron or mesh rating determines particulate removal capacity. This article examines these measurements in detail to guide selection.
Microns: The Standard Measurement
A micron (μm) equals one-millionth of a meter (1/1,000,000m), serving as the universal metric for microscopic particles. In filtration, the micron rating indicates the smallest particles a filter can capture.
For example, a 150-micron filter traps all particles larger than 150μm while permitting smaller substances to pass. Thus, lower micron values indicate finer filtration.
For perspective:
-
Coarse sand measures approximately 2000μm
-
Dust mites average 20μm in size
Higher micron ratings allow more particulate passage, while lower values restrict smaller contaminants.
Mesh: Rusco's Distinctive Measurement
Unlike industry-standard micron ratings, Rusco primarily uses mesh counts—the number of openings per square inch. For instance:
-
24 mesh = 24 openings/sq.in.
-
1000 mesh = 1000 openings/sq.in.
Contrary to micron ratings, higher mesh numbers indicate finer filtration. For example:
-
Pollen (≈370 mesh) would pass through lower mesh filters
-
Coffee grounds (≈50 mesh) require coarser filtration

Selection Guidelines
24-40 mesh:
Optimal for large particulates (sand, debris, pipe scale). Ideal for pre-filtration protecting downstream systems.
60-140 mesh:
Effective for fine sand and coarse silt. Balances filtration with water flow.
250-1000 mesh:
Designed for ultra-fine particles. Provides maximum filtration but may reduce flow rate.
