How much dust is your filter letting through? Filtration isn’t just about stopping dirt, it’s about stopping as much of it as possible. Even a small difference in efficiency has a massive impact on equipment protection. Take a look at the image. This test puts 1kg of dust into an air system. Here’s what gets through: - 99% efficiency 👉 10 grams of dust passed through - 99.9% efficiency 👉 1 gram of dust passed through - 99.99% efficiency 👉 Just 0.1 grams got through Now think about that over thousands of operating hours. A filter that isn’t truly efficient is letting contaminants eat away at your engine, causing premature wear, costly repairs, and downtime. That’s why Donaldson Blue filters deliver real protection, proven 99.99% efficiency, so your engine breathes the cleanest air possible. Small differences in efficiency = huge differences in protection. What are you trusting to protect your equipment? 📸 Credits: Jatinder Singh #Donaldson #Filtration #Educational
