The usage of Andreae filters
The Andreae filter is a great disposable filter designed to capture wet solids or liquid particles such as glues, paint, oils, fat, tar, etc.
The andreae filter can be used 3-5 times longer than e.g. glass fiber mats, and it can be a great advantage to use a prefilter in front of the andreae filter to expand the lifespan of the andreae filter.
The construction of the Andreae filter
The Andreae filter is constructed from a two ply, heavy duty cardboard. The V-shape of the filter ensures that particles are being filtrated.
