main types of filters used in the pharmaceutical industry 👇
🧪 1. Depth Filters
- Used for clarification and pre-filtration.
- Trap particles throughout the filter media (not just on the surface).
- Examples: Cartridge filters, sintered filters, filter pads.
💧 2. Surface Filters
- Capture particles on the surface of the filter medium.
- Provide precise filtration with defined pore size.
- Examples: Membrane filters, sparkler filters, filter paper.
⚗️ 3. Membrane Filters
- Used for sterile filtration and microbial removal.
- Common pore sizes: 0.2 µm for sterilizing, 0.45 µm for clarification.
- Applications: Water, air, and injectable liquid filtration.
🧫 4. HEPA Filters (High-Efficiency Particulate Air)
- Used in cleanrooms, HVAC systems, and laminar airflow units.
- Removes 99.97% of particles ≥ 0.3 µm.
- Ensures contamination-free air environment.
⚙️ 5. Cartridge Filters
- Cylindrical filters used for liquids and gases.
- Easy to replace and clean; available in various micron ratings.
- Used in water purification, solvents, and process gases.
🌡️ 6. Sparkler Filter Press
- Used for polishing and fine filtration of liquids.
- Provides crystal-clear filtrate with uniform pressure distribution.
- Suitable for syrups, oils, and liquid formulations.
🌬️ 7. Sintered Filters
- Made from sintered stainless steel or bronze.
- Used for gas filtration and high-temperature applications.
💨 8. Activated Carbon Filters
- Used for decolorization, odor removal, and purification of liquids.
