Nonwoven microfibre effectively reduces fine dust

May '08
The German Federal Institute for Risk Assessment (BfR) does not rule out the possibility of adverse effects on health caused by emissions from laser printers and copiers - and recommends individual preventative measures.

This statement is based on a recently completed pilot study project, the result of which was that a significant increase in the number of fine and ultra-fine particles in room air during printing and copying procedures can now be measured.

In its now-published evaluation of the project, the BfR sees the next step as being an examination of the physical and chemical composition of the measured particles.

Proof that a filter can perform properly is the voluntary test by the TÜV Nord and the presence of TÜV test seal which states "Effective protection against fine dust and toner dust". The micronAir Office Filter is the very first Fine Dust Filter to have received this official test seal.

The micronAir office Fine Dust Filter consists of environmentally-neutral, fully recyclable nonwovens in a triple-layer construction, one layer of which contains microfibers that are electrostatically-charged - and together, these layers permanently bind even the finest breathable ultra-fine particles, irrespective of their specific chemical composition.

The micronAir office Fine Dust Filter gets right down to its task - it's the most efficient fine and ultrafine printer dust filter you can buy.

With a filtering performance of well over 94%, the micronAir office printer filter captures even the smallest respirable particles - from a microscopic 100 nanometers to 2.0 µm - that's protection pure! Four separate filter effects work to protect you in every micronAir office Fine Dust Filter: the gravity, diffusion, electrostatic and "sieve" effects.

The micronAir office Fine Dust Filter profits from over 30 years of priceless know-how gained by Freudenberg Nonwovens in the development of innovative filter solutions.

Examples of the company's products are filters for clean rooms in the semiconductor industry, applications in the medical sector and automotive cabin air filters - two out of every three new vehicles in the world are fitted with micronAir cabin air filters.

"Now the real issue is to show consumers how they can already protect themselves effectively from fine dust emissions", said Harald von Schischka, Product Manager Human Protection Filtration at Freudenberg Nonwovens.

"A large proportion of these emissions consist of breathable, fine and ultra-fine dust particles. These can accumulate in the lungs - and are suspected of causing tumors.

The micronAir office Fine Dust Filter offers effective protection from these emissions - irrespective of the particles' chemical composition.

Oher additional measures can be taken too, like the regular maintenance of appliances, frequent room ventilation and having a room set aside for laser printers and copiers."

Whoever decides on a filter solution as protection from fine dust emissions must ensure that it is capable of filtering out even ultra-fine particles from the appliance's vented airflow.
