How does this air purifier work?
The ALUDO 6 series air purifiers are designed to suck in the air above the floor, remove dust, pet hair and coarse dirt from it through a pre-filter, and then pass it through special filters before returning it to the environment cleaned through three discharge openings.
This model has a HEPA 13 particle filter that filters out 99.95% of the smallest airborne particles, ranging in size from 0.1 microns to 10 microns.
What particles are filtered?
The HEPA particle filter filters the following substances from the air, among others:
- Fine dust
- aerosol particles exhaled by people (relevant for the transmission of viruses indoors)
- toner dust
For which application scenarios is this air purifier suitable?
Harmful health effects of particulate and gaseous air pollutants are well studied and documented both in the general population and in patients with various underlying diseases. These pollutants have effects on lung function and health, mortality, the cardiovascular system, metabolic processes, and fetal development. In addition, especially indoors, aerosol particles exhaled by humans pose a risk of contagion with diseases such as Covid-19.
Pollution prevention should always be the first priority. However, it is not possible to completely eliminate the causes of pollution everywhere.
ALUDO Series 6 air purifiers are the solution for all indoor spaces where it is impossible to exclude exposure to suspended particles. The modularly configurable filters of the ALUDO Series 6 can quickly and effectively reduce these substances in the air that are hazardous to health.
Can I reduce the risk of Covid 19 infection indoors with this device?
With this air purifier it is possible to keep the aerosol concentration in small and medium size rooms at a low level. This can greatly reduce the indirect risk of infection, even when windows are temporarily closed and there is no suitable ventilation system (as shown, for example, in this preprint from a Yale University research team). It is therefore very suitable for ensuring a low virus load on a permanent basis, for example in classrooms, stores, offices, waiting or treatment rooms. The air exchange rate is a decisive factor here.
It should be noted, however, that the direct risk of infection, which can occur through direct coughing or during long conversations over short distances, cannot be reduced by air purifiers. It is therefore important to continue to maintain sufficient distances from other people and to wear protective masks to avoid direct infection.
What air exchange rate is recommended?
The Federal Environmental Agency recommends that an air purifier as a ventilation support measure at schools during the Covid 19 pandemic should achieve at least five times the room volume in air flow rate. Other research suggests an air exchange rate of at least four times the room volume to effectively reduce hazardous aerosols (Kähler et al. 2020). For use in minimizing Sars-CoV-2 viral loads indoors, we assume an air exchange rate of 5 in the following.
For all other uses beyond Covid-19, an air exchange rate of at least 3 per hour is recommended.
Please note that a room in which people are present for long periods of time requires a supply of fresh air in addition to air purification solely for reasons of CO2 enrichment.
How large should the room be?
Our ALUDO air purifiers of series 6 can be operated in 9 different stages, with an air flow rate of up to 800 m³ per hour (the air flow rate values of all stages can be found under Technical Data/Delivery Volume). Assuming an air exchange rate of 5, you can operate this air purifier at its highest level in a room with a volume of up to 160 m³. If an air exchange rate of 3 is aimed at, ALUDO air purifiers can be used in rooms with a volume of up to 260 m³. For operation at lower levels, correspondingly smaller rooms are suitable.
To determine the air flow rate required for your room, first calculate the room volume. To do this, multiply the room area by the ceiling height. Now multiply the room volume by the targeted air exchange rate. The result is the required air flow rate (delivery volume) that your air purifier should provide in order to maintain the air quality in this room at the desired level on a permanent basis.
Where should I place the air purifier?
The device has outflow openings on three sides. To enable the most effective filtration of the room air, the air purifier should ideally be positioned on the longest side of the room in the middle. Practical tests (Kähler et al. 2020) have shown that the outflows towards the ceiling should not be interrupted by objects such as lamps as far as possible, as otherwise unfavorable vortex currents may become established in the room. It is recommended to operate the device in continuous mode and not only intermittently, so that no increased virus concentration can develop in the room.
How loud is the unit?
With dampening sound elements and an efficient motor, ALUDO Series 6 air purifiers are designed to be no louder than your breath at the lowest power level and remain below the level of common background noise in a living space even at higher power levels. At maximum power levels, the unit is about as loud as a refrigerator or a downpour. The exact decibel values can be found in the technical data.
How much power does the device consume?
With their efficient motor and three-dimensional fan geometry, the ALUDO Series 6 air purifiers are very power efficient. The power consumption depends on the program and power level with which you operate the device. You can find the respective values in the technical data.
Can I put anything on the unit?
Of course you can. The cover plate is durable and scratch-resistant.
How long will the device and its components last?
An ALUDO air purifier is a durable device. We offer a 10-year warranty on a product that, with proper care, will continue to make your life easier for many years to come.
The filters are consumable parts and must be replaced or cleaned at regular intervals. The pre-filter of the ALUDO 6 Life must be changed every 3 months on average. The HEPA particle filter has an average life of 18 months.
All filter modules can be easily removed and reinserted and combined as desired.
