The optimal mask selection for the correct application is critical for the wearer's overall protection and necessitates significant caution. There is a contrast to be established between the various different mask options in terms of certifications and product attributes.
Our masks meet the requirements of the European standard EN 149:2001+A1:2009 for filtering half masks to protect against particles. This explicit standard closely examines and accurately judges different performance tests: filter penetration, flammability, breathing resistance, and total internal leakage.
Our masks have also been put through a stress test according to EN 1327, 4-7, which is a paraffin oil test technique. The national standardizing organization can always provide a full extract of the EN149:2001+A1:2009 standard. In addition, our DODO mask passes the dolomite dust storage test. Furthermore, the DODO model is completely CE-certified and complies with DIN EN 149:2001+A1:2009 as well as the PPE regulation EU 2016/425. The certification was completed by Gepteszt (Budapest), an officially certified EU test center with the identification number 2233.
Overview of FFP2 model DODO
To preserve our normal level of transparency, we will go into the product characteristics of our FFP2 mask DODO below and present basic information in a brief overview:
Each of our FFP2 filter masks model DODO offers effective and reliable respiratory protection in industries where workers are exposed to fine dust particles.
Our DODO model has been tested and approved with the official CE mark, according to the European standard EN149:2001+A1:2009.
Our flat design enables space-saving storage of the product.
The shape of the front increases the dimensional stability of the mask.
Our DODO mask can also be used in warm, humid environments
Manufactured in 4 layers.
The ear loops of the FFP2 mask DODO allow an effortless adjustment to the face and head.
The nose clip supports the optimal fit.
In addition to the general nature of an FFP2 mask, the respective work areas for protective use and the choice of the right mask to be derived from this play a decisive role.
The selection of the most appropriate personal protective equipment (PPE) depends on the situation and should be made by a competent person who understands the risks, working conditions, and limitations of the PPE. More detailed information on performance features and limitations can be found on each of our product packaging for easy reference. If in doubt, please get in touch with the relevant specialist department in your company or with a contact person at PPE Germany.
Areas of Application
Our DODO model can be used in many industries where workers are exposed to particulate matter and/or non-volatile liquids.
Examples of practical use are:
Pest Control (Water-Based)
Plant and Equipment Maintenance
Our DODO respirators are suitable for use with solid and non-volatile liquid particles up to the following concentrations: 10 times the limit value. Only if the respirator is properly selected, fitted, and worn for the entire time the wearer is exposed to a toxin will it be effective.
Structure of the DODO mask
Filter material or four layers of polypropylene are generally used to make the masks. Spunbonded and melt-blown nonwovens make up this category.
Melt-blown non-woven fabric is currently used in the majority of protective masks on the market. Meltblown material is the technical term for this melt-blown nonwoven. Electrostatic adsorption is the process that filters PM2.5 particles and viruses in this melt-blown substance. The collection of chemicals from gases or liquids on the surface of a solid, or more broadly on the interface between two phases, is referred to as adsorption.
The particle diameter of particles in the air (= air pollution of any kind) that should be filtered out by the proper respirator is referred to as PM2.5. Respirable fine dust particles with an aerodynamic diameter of less than 2.5 m (Particulate Matter 2.5 m, where 1 m = 1 micrometer = 1 millionth of a meter) are more clearly characterized. Without an FFP2 or FFP3 respirator, PM10 (particulate matter smaller than 10 microns) reaches the top of the lungs. For reliable protection against poisonous dust or other hazardous compounds, such as mold, use a mask of class FFP2 or a higher protection class, such as the FFP3 respirator. Absorption is different from electrostatic adsorption in that it involves chemicals penetrating the interior of a solid or liquid.
After unpacking, any material odor from the masks is natural, innocuous, and goes away in a short time. There are no natural rubber components in the products. The ear loops are made of a safe thermoplastic elastomer, whereas the nose clip is made of steel or plastic. The overall weight of all protective components adds up to 4.5 g per mask.
Restrictions on filter performance
The filtration function of simpler respirators is drastically decreased when they are exposed to water or moisture. Viruses are invisible to the naked eye. The virus is between 60 and 140 nanometers in size, according to electron microscope tests, and is mainly transmitted through droplets and aerosols. When the viral carrier coughs or sneezes, aerosols are simply inhaled by persons without airway protection. As a result, infections can spread through the air we breathe. This indicates that infection mainly arises as a result of close human contact or inhalation of virus-infected respiratory air aerosols transmitted through the respiratory system from other sick persons to healthy people. As a result, the virus enters the body through the nose, mouth, and throat.
These viruses are not free in the air we breathe but are intimately integrated into it (in so-called aerosols). These viral particles, which escape in the form of aerosols when transmitted through respiratory secretions or breathing air, are on average less than five micrometers in size.
Breathable and waterproof are two words that come to mind when describing our protective mask. It traps PM 2.5 particles (2.5 m = 0.0025 mm), which have an aerodynamic diameter of fewer than 2.5 microns. Secondary aerosols and combustion make up the majority of these particles. Such little particles easily pass through the respiratory system and into the alveoli. In addition to the conventional droplet transmission into the human body, our DODO mask prevents germs, microbes, bacteria, and an aerosol-bound concentration of viruses from penetrating us, humans.
After using the mask
On the product packaging, the expiration date is always clearly visible. Always check whether the current product is still durable before using it. The mask must be stored and carried in its original packaging, clean and dry, between 5°C and +25°C, with a maximum humidity of 60%. In principle, it is impossible to make a broad statement on the service life of breathing masks. Disposable masks should only be worn for one work shift at most (eight hours).
If the breathing resistance rises quickly, the mask should be replaced sooner rather than later. Reusable mask filters can be used for several work shifts. The following applies regardless of the type of filter: The filter must be replaced as soon as breathing resistance increases, or as soon as a gas taste or smell is detected. The same is true once the filter's minimum durability has been exceeded. Please follow the regional disposal requirements when discarding used DODO respirators.
When it comes to picking the ideal respiratory protection, it's also crucial to wear the mask correctly. The amount of overall leakage determines the protective effect. This consists of the filter passage and "missed leakage," which is produced by leaks between the mask's sealing line and the wearer's face. Both qualities of the FFP masks are tested by DIN EN 149.
