Walter Replacement Foam Pre-Filters 10-Pack

Protect Your Lungs and Your Equipment

As a welder, you know that a good fume extractor is your best friend when it comes to long-term health. The Walter Foam Pre-Filter (10 Pack) is designed to keep that equipment running smoothly so you can focus on laying perfect beads. These pre-filters sit at the intake of your extraction unit, catching the heavy stuff—grinding dust, large soot particles, and stray sparks—before they get deep into the machine.

Why is this important? Your fume extractor likely uses a high-efficiency main filter to trap dangerous microscopic fumes. If that main filter gets clogged with big chunks of dust, it loses suction and burns out faster, costing you money. By swapping out these affordable foam pre-filters regularly, you protect the expensive heart of your machine and ensure it keeps pulling fumes away from your face effectively.

This 10-pack is perfect for busy shops. You can keep a stack on the shelf and swap them out whenever they look dirty, ensuring you never experience downtime due to a clogged system. They are easy to install and fit perfectly into compatible Walter extraction units. Don't let a clogged filter ruin your airflow; keep your shop air clean and your equipment happy with these essential replacements.

Why Welders Need This

• Better Suction: Keeps airflow strong by preventing clogs.
• Easy Maintenance: Quick to swap out in seconds.
• Value: A small investment that saves your expensive main filter.
