Filters can be divided into different types depending on their application, function and medium. Below are a list of common filter types and typical application scenarios from different angles:
I. By media
Air Filters
Efficacy: Removes dust, pollen, bacteria, odors and other harmful substances from the air.
Classification:
By Filtration Efficiency: thick (≥5μm), medium (≥ 1 m), high efficiency (≥ 0.3 m), Ultra-High Efficiency (≥ 0.1 m) filters.
By structure: flat filter, bag filter, pleated skirt filter, electrostatic filter, honeycomb filter, etc.
Application Scenarios: Air conditioning system, cleaning room, industrial dust removal.
Liquid Filters
Function: Filter impurities, particles or microorganisms in liquid.
Classification:
Hydraulic Oil Filters: Suction oil filters, oil return filter, pipeline filters.
Food Filters: dust filters, air conditioning filters.
Pharmaceutical Filters: Drug filters, respiratory filters, blood filters.
Application Scenarios: Hydraulic systems, food processing, pharmaceutical production. Web Filters
Function: Filter or control network data flow (e.g., content filtering, security).
Typical tool: filtering in SEO keyword analysis tools such as Ahrefs, Semrush, allowing keyword filtering based on search volume, difficulty, intent, etc.
Application Scenarios: SEO optimization, content marketing.
II. By function
Self-Cleaning Filters
Function: Automatic removal of impurities on filter screen, reduce manual maintenance.
Application Scenarios: Industrial water recycling system, municipal water supply.
Fully Automatic Filters
Function: Automatic filtering through sensor and control system.
Application Scenarios: Large Industrial Equipment, Commercial building air conditioning systems.
Brush Filters
Function: Use brush to clean impurities on filter surface.
Application Scenarios: Cooling water systems, irrigation systems.
III. By Driving Force
Gravity Filters
How it works: Relying on gravity to move liquids through filtered media.
Application Scenarios: Small laboratory filtration, simple liquid purification.
Vacuum Filters
Principle: The vacuum pump produces negative pressure to accelerate the filtration process.
Application Scenarios: Chemical Experiment, pharmaceutical industry.
Pressure Filters
How it works: Liquid passes through a filtration medium under external pressure.
Uses: Industrial high-viscosity liquid filtration, wastewater treatment.
IV. INTRODUCTION By Industry
Industrial Filters
Type: Pipeline filter, doublecylinder filter, high pressure filter.
Application field: petrochemical industry, power industries.
Food and Pharmaceutical Filters
Type: Bacterial filters, sterile filter.
Purpose: Beverage production, drug injection filtration.
