Importance of Using Fleece Bags in a Dust Extractor

Fleece Bags vs Filter Replacement: What’s the REAL COST?

Dust Extractor Fleece Bags are less expensive to use and replace than the vacuum pleated filters. Using fleece filter bags drastically improves the lifespan of both standard and HEPA filters, and protects the vacuum motor. Using them provides you with a massive cost savings over the course of a year, or lifespan of the vacuum unit.

The table below shows the cost of fleece bags is more economical than the cost for a standard filter [2 pack] replacement for the vacuum.

Importance of Using Fleece Bags in a Dust Extractor: 4 Reasons

Below are four reasons to use dust extractor fleece bags. Probably the BIGGEST and most important reason to use fleece filter bags is to keep Silica, lead dust and other harmful dust exposure to a minimum when emptying the vacuum.

Durability

Fleece filter bags are more durable than their paper counterparts. If you are a painter or drywall finisher and using your dust extractor exclusively for sanding dust you might be OK with paper filter bags. But with general use and cleanup we find the durability of fleece bags to be necessary.

Exposure / Safety

Emptying a vacuum canister exposes the user to dust inhalation but Fleece bags unhook from the vacuum inlet and can be closed off, thrown away, minimizing and eliminating exposure to silica, lead paint or other  harmful agents.

Performance

Fleece bags provide a redundant protection the the vacuum meter and bearings. Even with auto filter clean, present on all of these extractors, the filters eventually will get clogged up or could develop a tear. Experience has shown that insulation, coarse sawdust and fine particulate matter can ruin the filter over time. Fleece filters help maintain suction, and protect the main, more expensive filters, and vacuum motor.

Annual Cost Filter vs Fleece Bags

Assuming remodeling jobsite use and using the Bosch dust extractor I will go through a pack of bags on a kitchen and powder room remodel. This is an occupied space so I am cleaning up the whole site with this dust extractor every day. If I were not using filter bags I would replace the filter at the end of this job. Total job duration will be approximately 4 months (frame to high end finish). So for the estimated cost of use, I am assuming 4 packs of filter bags or 4 filters annually.
