Effective room air filtration for a high level of safety!

Air purifier SilentCare with HEPA filter


Clean air free of viruses, bacteria and other pollutants significantly promotes our health. Especially in rooms with a high number of people, the number of airborne pollutants increases rapidly, thus greatly increasing the risk of infection with pathogens.

The SilentCare air purifier with HEPA-filter function from Filtration Group Industrial is the perfect solution, especially for rooms where the supply of fresh air cannot be guaranteed to the optimum extent. This filters the ambient air regularly and, above all, very quietly. The noise level of SilentCare is well below the average noise level of an office of approx. 50 – 60 dB(A) and guarantees trouble-free working.


HEPA filter element

The air purifier SilentCare is equipped with a HEPA filter.

HEPA filter in separation class H14 according to EN1822

(filters at least 99.995 % of pollutant particles in the range 0.1 – 0.3 µm)

The three-layer filter medium, certified according to the European standard EN1822, ensures efficient filtration of almost all aerosols present in the ambient air of closed rooms. This allows pollutants to be reduced to a minimum. The filtering micro glass fiber layer is embedded between two polyester non-wovens. This prevents contact with the filter layer.



Activated carbon filter element

Add an activated carbon element to your SilentCare room air filter and remove unpleasant odors from your room air.


  • Element type: 852 series
  • Part-number: 72495489
  • Height (mm): 200
  • Outer diameter (mm): 500
  • Element design: cylindrical



Quiet and draft-free operation

The SilentCare air purifier with HEPA filter guarantees extremely quiet and draught-free operation (43 dB(A)) with optimal air circulation compared to devies on the market due to large filter surface.

Multi-stage operation enables individual adaptation to room use, provided that intermittent ventilation is not possible between two changes of use. It is possible to achieve higher air exchange rates via the boost function and thus specifically filter out possible pollutants from the air.


Air circulation and purification

The SilentCare air purifier with HEPA filter function scores with the following details:

  • 360° air circulation and cleaning
  • Airflow from 600 m³/h +/- 50 m³/h (max. 900 m³/h +/- 50 m³/h)
  • 5-fold air exchange per hour for rooms up to max. 70 m²


The SilentCare room air filter with HEPA filter function is a product manufactured in Germany – “made in Germany”. Thanks to a simple design, the device is mobile and flexible due to rollers and scores with a small footprint. The room air filter convinces with a very low energy consumption.

Also suitable for allergy sufferers?

Many people are affected by allergies nowadays. The triger can be a biogenic, chemical and particulate pollutant.

The VDI Guideline 6022 Sheet 5 describes requirements for the testing and assessment of technical equipment provided to prevent allergenic exposure. Among other things, portable air cleaners are also dealt with.

Due to extremely good separation of the filter element, it can be assumed that almost no allergy-causing aerosols (particles) are present in the filtered air.

The filter material is a three-layer structure and consists of polyester fibres on the outside and glass fibres in the actual filter layer. There are predominantly water-repellent, so that fungi and other organisms can grow poorly or not at all on the material. The adhesive of the filter element has been approved for use with foodstuffs and can therefore be considered harmless.

Notice: The SilentCare has not been tested by an independent testing institute according to the guideline VDI 6022 part 5. The suitability of the SilentCare for the separation of allergenic aerosols was derived from existing data of other standards.

What does the SilentCare have that other air purifiers do not?

The FG SilentCare has a volume flow of 600 m³ per hour or 900 m³ per hour in the second stage, this ensures the required air exchange of 5 to 6 times per hour for very many rooms. The low noise level, which corresponds to a printer at most, is much quieter than the noise level in a normal office.

The SilentCare convinces with many advantages and has a price/performance optimum in the categories

  • Technology
  • Handling
  • Noise level
  • Separation efficiency, service life
  • Energy consumption and design

The SilentCare can be mounted with a wall bracket for additional stability. In addition, it can still be equipped with a motion detector, which can be used to automatically switch the mobile device on and off.

Support programs for air purifiers


To protect the health of children and young people, the German government is providing a total of 200 million euros for the purchase of mobile air purification devices. The devices are intended to help reduce the risk of infection as far as possible and protect the health of school and daycare children. The funding share is up to 50 percent. Applications for funding and implementation are handled by the federal states.


Companies receive financial support from the federal government through Bridging Assistance III and can thus compensate to some extent for financial losses from the Corona pandemic.

Acquisition costs for air purifiers purchased for business purposes as of September 1, 2020 may also be covered by this grant, among others. The following reimbursements for bridging assistance (2nd phase) apply:

  • For ≥ 30 to
  • For ≥ 50 to ≤ 70 percent decrease in sales, 40 percent of eligible fixed costs are reimbursed
  • If > 70 percent decrease in sales, 90 percent of eligible fixed costs are reimbursed

Current information as of July 14, 2021: The federal government is providing 200 million euros for mobile air filters in schools and daycare centers.


The Bavarian state government provides funding for the procurement of mobile air purification units and decentralized ventilation systems. The subsidy program is valid for mobile air purification devices with filter technology, UV-C technology, ionization and plasma technology or for a combination of these technologies. Up to 50% of the purchase costs can be subsidized, up to a maximum of €1,750 per room. The program is valid from 01 May 2021.

Efficient methodology

For clean air

Ventilation versus room air filter

  • Room air filters ensure continuously adequate room air quality. Manual regulation by means of windows is no longer necessary.
  • To prevent indirect infections, an adequate supply of fresh air or very good filtration of the room air is required.
  • With shock ventilation, the existing concentration of pollutants in the room can be greatly reduced within a very short time under suitable wind conditions or temperature differences. After closing the windows, the concentration gradually increases again.
  • In order to keep the concentration of pollutants at a low level, it is therefore necessary to provide frequent shock ventilation or, better, continuous ventilation.
