Fine dust filter for laser printers

Extensive testing has proven that laser printers emit particulate matter. That’s why the air quality in some offices is worse than the air in the immediate area of a freeway with average traffic levels.

Why is fine dust so dangerous?

Fine dust is an air pollutant and poses a risk to health - and the earth's climate. The fine dust particles can enter the human body through respiration and cause a wide variety of negative reactions.
Depending on the size of the particles, high levels of particulate matter promote the development of asthma, allergies, cardiovascular disease and even cancer. Smaller dust particles, e.g. from laser printers, settle much more easily in the body.
The biggest sources of particulate matter outdoors include combustion engines, coal-fired power plants, industrial facilities, brake and tire abrasion from vehicles, and agriculture.
Indoors, laser printers are among the most important sources of particulate matter, along with toasters, candles and gas stoves. In offices, therefore, widely used laser printers are a potential risk. Many workers spend their entire working hours not far from them, unknowingly exposing themselves to health hazards.
Fine dust filters for laser printers significantly reduce the contamination of office air. Furthermore, if the office rooms are ventilated regularly, the air quality is improved even further.

70 percent of German workers potentially affected

Fine dust emissions from laser printers pose a health risk to German workers, according to recent research. More than 70% of the printing devices used in German offices are laser printers, which release dust particles that are invisible to the eye with every printout and can enter the lungs and even the bloodstream through inhalation. The fine dust pollution in office rooms caused by some printer models even equals that of a main traffic road.

Health risk fine dust

Health effects of particulate matter emissions depend on the size of the particles. Larger fine dust particles, which are emitted by cars, for example, settle more heavily in the body than very small fine dust from laser printers. The smaller the particles, the more frequently health impairments of the entire organ system are observed. Ultra-fine dusts are among the highly carcinogenic particles and are therefore particularly harmful. According to studies, particles with an average size of less than 10 micrometers can worsen lung function, while particles smaller than 2.5 micrometers can already trigger systemic disease effects such as tumors or cardiovascular failure.[3]

How the fine dust filter for laser printer works

The new particulate filter consists of environmentally compatible, completely recyclable nonwoven fabrics. Thanks to its three-layer structure and the electrostatically charged microfibers in the middle layer, even the smallest particles, which can enter the lungs, are permanently absorbed – regardless of the specific chemical composition of the particulates emitted.

Each of the three layers performs an important task:

  • The first layer filters larger dust particles.
  • The second layer binds smaller particles thanks to electrostatically charged microfibers.
  • The third layer is extremely fine-pored and filters even the smallest fine dust particles

tesa Clean Air is available in three sizes

S: 100 x 80 mm, M: 140 x 70 mm and L: 140 x 100mm

Effective protection against fine dust from laser printers. Extensive tests have shown that laser printers emit fine dust. Some models emit so much fine dust that the air in some offices is more polluting than in the immediate vicinity of an average motorway. This was found by Australian physicists from the Queensland University of Technology1. The tesa Clean Air fine dust filter creates a clean working atmosphere.
  • Thorough effect: tesa Clean Air filters up to 94 percent 2 of all fine dust particles.
  • Excellent performance: The way tesa Clean Air works was certified by the TÜV North certified. The European Foundation for Allergy Research (ECARF) has awarded the filter material from tesa Clean Air® with the ECARF seal of approval for allergy-friendly products.
  • Easy to use: tesa Clean Air® can be attached quickly and easily, available in three Sizes S, M, L
  • Long-term protection: optimal filter performance from tesa Clean Air is supported for 70,000 prints or up to 12 months.
  • tesa Clean Air is made using a high-quality and self-adhesive hook-and-loop system simply attached to the ventilation duct of the printer. This does not affect the ventilation of the printer. The fine dust filter from tesa Clean Air consists of a three-layer special fleece that filters even the finest dust particles. The innovative high-performance fleece is extremely absorbent and can be disposed of with household waste.
  • Size S: 140x100mm
