How to Find the Right Filter

There are several ways to identify the best filter for your system:

1. Ask a Specialist

If your system was installed by a technician or distributor, ask them what filter types and micron ratings you need. Common options include:

• Particulate filters – trap dust and solid particles

• Coalescing filters – remove oil and water aerosols

• Activated carbon filters – eliminate odors and vapors

2. Check the System Specs

Most compressors and filter housings list the compatible filter element part numbers. Always follow the manufacturer’s guidelines instead of guessing.

3. Use the Current Filter as a Reference

If you’re replacing a filter, remove the old element and note any part numbers or specifications on the casing. You can also take a photo and show it to your supplier to ensure you get the right match.

4. Consider Micron Ratings & ISO Standards

Unlike HVAC filters that use MERV ratings, compressed air filters are classified by micron size (e.g., 1 μm, 0.01 μm) and ISO 8573-1 air quality standards.

• General shop air: 1–5 μm filters work well

• Paint/food/medical use: 0.01 μm + activated carbon may be required
