What is PAPR (Powered Air Purifying Respirator)?
PAPRs, known as electric air-purifying devices, can be defined as breathing devices that protect the user by filtering pollutants in the air and use a tight-fitting respirator, a loose-fitting hood, or a battery-powered blower to provide clean air to the user through a helmet.
- An electric air-purifying respirator (PAPR) is a battery-powered respirator that cleans the incoming air before a person breathes.
- A fan passes air through the filters in the cartridges. The purified air then flows into a mask, headgear, or face mask that covers the person’s nose and mouth.
- PAPRs are used in industrial and commercial environments and by emergency responders and healthcare professionals.
- Although the word “respirator” is already part of the abbreviation PAPR, the device is often referred to as a PAPR respirator.

Armour PAPR Components
The N95 breathing mask is a breathing mask that is classified as N95 in the air filtering standard of the US National Institute of Occupational Safety and Health and has the ability to filter at least 95% of inhaled air particles of 5 microns and above.
PAPRs are devices operating under positive pressure.
Unlike N95 type face masks operating under negative pressure (vacuum), it provides filtered clean air to the environment with the fresh air flow, which is pre-filtered and directly presented to the user by the airflow channels in the hose and the nozzle. It also prevents the entry of unwanted particles or pollutions.
It is suitable for the use of all healthcare professionals who are in the first-degree contact with patients in the sector such as hospitals, private practices, dental polyclinics, ambulances, dermatology, and aesthetic clinics.
The HEPA 13 Medical Grade special filter, which is preferred in the filtering apparatus, can filter bacteria and viruses and save the user from seriously disturbing protection equipment such as face masks, goggles, and visors for long hours.
- HEPA filters, defined by the United States Department of Energy (DOE) standard adopted by most American industries, remove at least 99.97% of airborne particles with a diameter of 0.3 micrometers (μm).
- Hepa filters, (High-Efficiency Particulate Arresting), absorb particles suspended in the air. Hepa filter usage is preferred to minimize the damage caused by the particles in the air to the environment or to the environment.
Sealing features (Leakage) are the most critical feature of PAPR type respirators and actually determines the performance and reliability.
For exactly this reason, when designing the filtering apparatus of Armour PAPR, it was aimed to achieve the highest sealing performance.
It is positioned in 3 different regions within the filtering apparatus.
Central Screwing System
The sealing has been brought to an extremely high level with the screws centered on the four corners extending to the front and rear molds of the filtering mold and including the filter casing.
Unlike surgical masks or n95 mouth masks, PAPRs are devices that work under positive pressure. In the device designed with this working principle, there is a continuous filtered clean airflow into the head and the ambient internal pressure is higher than the external pressure. In this case, it is not possible to enter any air through the neck collar and overalls.
From the parts of Armour PAPR, hood, hose, filter, battery, charger, and overalls can be sold individually. You can access these parts by specifying the product code if you need them or want to back them up.
The lifetime of the listed spare parts; Although it varies according to the ambient conditions for the header and filter, it is as follows.
No! Since Armour PAPR filters the ambient air with a HEPA filter with superior filtering power and provides clean air to the user with the help of a flexible hose and a special air duct in the nozzle, there is no need to wear a mouth mask.
N95 type masks are called with this name because they show 95% success at 5-micron particle size as filtration performance efficiency. However, Armour PAPR works with a 0.3-micron particle size HEPA filter with 99.97% filtration efficiency, superior to any N95 mask. Thanks to its HEPA filter, Armour PAPR provides its user with superior protection than any N95 mask, and its sealing performance is much higher since it operates under positive pressure.
You can wipe all spare parts with a disinfectant containing 70-80% alcohol and sterilize all parts in the UVC ray cabinet.
N95 mask and Armour PAPR differences
|1. It shows 95% efficiency at 5-micron particle size.||1. It shows 99.95% efficiency at 0.3-micron particle size.|
|2. It works under negative pressure.||2. It works under positive pressure.|
|3. It should be checked initially whether it is sitting properly on the user.||3. The sealing feature is maximized thanks to the screwing and sealing gaskets specially designed for the Armour filtering apparatus.|
|4. It may cause leakage and not fitting to the face due to reasons such as beard and hair.||4. It does not give a feeling of sweating, humidification, or temperature increase in long-term use. It provides comfortable use.|
|5. In prolonged use, it causes severe deformation of the face and can become painful.||5. Since it is not a mask that fits directly on the face, it does not cause injury and discomfort problems.|
|6. It feels moist and uncomfortable over time.||6. It can be used for many years when it is disinfected and the filter is changed at appropriate intervals.|
|7. They are disposable masks.|
