The importance of replacing filters in plant machinery

24th October 2023 Holm Education

Most plant machinery comes with manufacturers guidance on when and why the different filters will need replacing. With much experience, that knowledge is second nature to a lot of plant engineers that have been in the trade for years. But we want to be sure that you can get the most out of your machines as you use them now and when you come to sell them.


Here's a quick list of reasons replacing filters is so important:

  • Improved efficiency. Put simply, when filters are clean and new, they keep machines running smoothly. On the other hand, clogged filters slow things down, reducing power and productivity.
  • Save on fuel. Dirty filters make engines work harder, burning more fuel and costing you money.
  • Engine longevity. Engines are the heart of your machines, neglecting filters can damage them. Think of it as giving your machine a healthy heart.
  • Longer machine life. Regular filter changes mean a longer life for your machinery.
  • Cost-effective maintenance. Ignoring filters leads to expensive repairs. It's cheaper to keep maintenance up to date..
  • Prevent downtime. Breakdowns are costly. Changing filters helps avoid extra or unexpected downtime.
  • Regulatory compliance. Compliance with emissions regulations is a must. Keep filters fresh to stay on the right side of the law.
  • Clean air inside. Operator comfort matters. Fresh cabin filters ensure clean cabin air.
  • Maintain resale value. Changing filters is an investment. It keeps your machinery's value high.
  • Don't forget the Hydraulic filters. These are often overlooked. If they fail, they can cause the pump to fail - a very expensive part to replace.


In engineering terms, filters are a machine's lifeline. Keep them fresh, and your equipment will run more efficiently, last longer, and stay compliant with regulations. It's all about efficiency, cost savings, and taking good care of your machines.
