Understanding Micron Bag Size Charts for Better Filtration Results
When selecting a bubble bag filtration system, one of the most important factors is understanding the micron bag size chart. Different micron ratings determine how particles are separated, collected, and filtered during the extraction process. Choosing the correct micron size can significantly improve filtration efficiency, product consistency, and overall process performance.

Whether you’re purchasing a complete bubble bag kit, replacing individual filter bags, or designing a custom filtration setup, understanding micron sizes is essential for achieving reliable results.
As a professional manufacturer and supplier, ExtractLab specializes in producing high-quality custom bubble bags with precise mesh specifications, durable materials, and OEM customization options for distributors, brands, and industrial users worldwide.
What Is a Micron in Bubble Bag Filtration?
A micron (μm) is a unit of measurement equal to one-millionth of a meter. In bubble bag filtration systems, the micron rating refers to the size of the mesh openings that allow particles of certain sizes to pass through while retaining larger materials.
The smaller the micron number:
- The finer the filtration
- The smaller the particles retained
- The slower the flow rate
The larger the micron number:
- The faster the drainage
- The larger the particles filtered
- The higher the throughput
Understanding these differences helps users optimize separation efficiency and achieve more consistent filtration results.
Standard Micron Bag Size Chart
The following micron bag size chart represents the most commonly used bubble bag filtration sizes available on the market.

| Micron Size | Mesh Opening Size | Typical Function |
|---|---|---|
| 220 Micron | Extra Coarse | Initial filtration, removes large contaminants |
| 190 Micron | Coarse | Pre-filtering large particles |
| 160 Micron | Medium-Coarse | Intermediate separation |
| 120 Micron | Medium | General filtration stage |
| 90 Micron | Medium-Fine | Fine particle collection |
| 73 Micron | Fine | Precision separation |
| 45 Micron | Very Fine | Captures smaller particles |
| 25 Micron | Ultra Fine | Finest filtration stage |
Many commercial bubble bag kits use combinations of these sizes to create a multi-stage filtration process.
Why Micron Size Matters
Selecting the wrong micron size can lead to several problems:
Reduced Filtration Efficiency
If the mesh opening is too large, unwanted particles may pass through the filter.
Lower Product Quality
Improper separation can result in inconsistent filtration performance and reduced purity.
Slower Workflow
Using excessively fine bags in early filtration stages may cause clogging and reduce throughput.
Increased Operating Costs
Incorrect bag selection often leads to more frequent cleaning, replacement, or process adjustments.
For optimal results, many professionals use multiple micron sizes in sequence rather than relying on a single filter bag.
Common Bubble Bag Configurations
5-Bag Filtration System
A 5-bag setup is one of the most popular configurations due to its balance between efficiency and affordability.
Typical micron sizes include:
- 220μm
- 160μm
- 120μm
- 73μm
- 25μm
Benefits:
- Easy to operate
- Cost-effective
- Suitable for most filtration applications
- Faster setup and cleaning
8-Bag Filtration System
For users seeking more precise particle separation, an 8-bag configuration offers greater control.
Typical micron sizes include:
- 220μm
- 190μm
- 160μm
- 120μm
- 90μm
- 73μm
- 45μm
- 25μm
Benefits:
- Improved separation accuracy
- Better consistency
- Enhanced filtration flexibility
- Greater process control

How to Read a Micron Bag Size Chart
When reviewing a micron bag size chart, keep the following principles in mind:
Larger Micron Numbers = Larger Openings
Examples:
- 220μm
- 190μm
- 160μm
These bags act as pre-filters and allow faster drainage.
Smaller Micron Numbers = Smaller Openings
Examples:
- 73μm
- 45μm
- 25μm
These bags provide finer filtration and retain smaller particles.
Filtration Progresses from Large to Small
A standard filtration sequence generally starts with the largest micron bag and moves progressively toward finer mesh sizes.
This staged approach improves filtration efficiency while reducing clogging.
Key Technical Parameters to Consider
While micron rating is important, several other technical specifications also influence filtration performance.
Mesh Material
Common materials include:
Nylon Mesh

Advantages:
- Excellent tensile strength
- High durability
- Precise mesh openings
- Long service life
Nylon Canvas + Mesh

Advantages:
- Enhanced structural support
- Improved seam durability
- Better handling during operation
At ExtractLab, we offer both configurations depending on customer requirements.
Mesh Accuracy
High-quality bubble bags should maintain consistent mesh openings across the entire filtration surface.
Benefits include:
- Uniform filtration
- Reliable performance
- Reduced variability
Seam Construction
Professional manufacturing methods include:
- Double stitching
- Reinforced seams
- Industrial-grade thread
These features significantly improve product lifespan.
Material Safety
Premium filtration bags should feature:
- Food-grade materials
- Chemical-resistant fabrics
- Washable and reusable construction
Applications of Bubble Bags
Bubble bags are widely used in industries requiring precise particle separation and filtration.
