How to ensure the best performances on the Andreae® Filters Original?

The Andreae®Filters Original is designed with two extension limiters which guarantee the correct opening of the filter, to maximise its loading capacity.

The extension limiters should be correctly positioned & glued between the 2 paper layers: it stretches when the filter is opened to guarantee its recommended opening to reach the best performances.

If the limiters are not stretched when the filter is opened, neither properly fixed, they are useless!
