AG25: 30.9 kWh/p.a. at €0.77/month; 2 cents/day AG300: 37.8 kWh/p.a. at €0.95/month; 4 cents/day AG600: 74.5 kWh/p.a. at €1.86/month; 7 cents/day AG900: 188.8 kWh/p.a. at €4.72/month; 18 cents/day In direct comparison, an energy-saving lamp (13 watts) requires 44.6 kWh. The AG25 and AG300 are therefore even below the power consumption of an energy-saving lamp. 1) Assumption: 6 days per week / 11 hours of use per day / 52 weeks / power level 2 / kWh = 30 cents

The filters must be changed every 8 - 24 months depending on use.

AG25 & AG300: along with the filters AG600 & AG900: after 6000 - 7000 hours, the filter change is indicated separately (flashing lamp) at approx. 2 years1) All devices indicate a corresponding change of filters and modules in the display or by flashing.

The type of disposal for the filter elements is essentially related to their use. If the use takes place in a normal public area (e.g. a classroom, office etc.) we can assume that the contamination of the filters is relatively harmless. The filters can be considered as industrial waste and are available as residue /commercial waste, e.g. to be disposed of in an industrial waste incineration plant. Use PSA2) yourself when replacing the filter. Contaminated filters due to contamination by pathogens and toxins (e.g. when used in hospitals, doctors, laboratories, ...) are disposed of as hazardous waste in accordance with the environmental protection regulations in force there. In accordance with the applicable legal framework for hazardous waste, the permitted disposal route must be documented by means of the required disposal certificate. The Titanium Pro modules and UVC/UVA lamps count as "mercury-containing illuminants" when disposed of and are electronic scrap within the meaning of the Electrical and Electronic Equipment Act (ElektroG). Private and commercial consumers are obliged to dispose of the products mentioned separately from household waste. Appropriate collection points have been set up by the municipalities and districts (recycling depots). 2) Depending on the assumed type and intensity of the contamination of the filters, there is a different risk / hazard potential in the sense of a hazard assessment. The PPE must be selected and used accordingly. The basic recommendation for maintenance work such as filter changes relating to air conditioning devices and systems is the use of (Disposable) gloves Respiratory protection such as a face mask (FFP2, FFP3) U Safety goggles (... e.g. when working overhead) Dirty and spent filters should be carefully packed in a resealable airtight bag to prevent further contaminants from escaping

The great advantage here is the neutralization of bacteria, mold, viruses and allergens. HEPA filters only filter out these components, but do not neutralize them.

The hydroxyl radical plays an important role in summer smog and in the breakdown of many trace gases and is therefore also called Labeled "detergent of the atmosphere". The half-life of this molecule is far less than 1 second3), which means that it disintegrates in a very short time. Due to the high responsiveness and rapid decay, the reaction already takes place in the device. Further information can also be found at https://kenternext.de/airgle/ 3) *Half-life 10-9 seconds (Sies, Helmut (March 1993). "Strategies of antioxidant defense". European Journal of Biochemistry. 215 (2): 213–219)

Airgle devices use a patented (US 8,557,188 B2) technology that is used in addition to classic air filtration. This module uses a UV photocatalyst (PCO). The main principle is that the first nano titanium dioxide carrier is coated on the substrate surface with TiO2, which forms strongly oxidizing hydroxyl radicals with UV irradiation. These hydroxyl radicals oxidize pollutants in the air and break them down into simple molecules like carbon dioxide and water. They neutralize living spores in the air, bacteria, mold, viruses and allergens.

The c in cHEPA stands for Cleanroom. In fact, Airgle cHEPA filter technology removes pollutants down to 0.003 microns with an efficiency of 99.999%, putting it between H14 and U15. A cHEPA filter is 100 times finer than an H14 filter, which has a pore size of 0.3 µm. A crucial detail, because corona viruses with a size of approx. 100 - 120 nm cannot pass through the cHEPA filter, but under certain circumstances they can penetrate the H14 filter.

The fine dust content (PM) is measured on the Airgle devices. In automatic mode, the device does not react to a higher VOC / CO2 load -> a higher level should be selected manually if necessary. In addition to the fine dust content, the i-Air Pro also measures the VOC content - so it also reacts to a corresponding increase in the room air. The CO2 content is also not taken into account with this device.

A wavelength of around 185 nm is required to generate ozone. However, Airgle devices use a wavelength of 200-280 nm to excite the TiO2. Since the UV light has the "wrong" wavelength, so to speak, no ozone4) can be produced in the Airgle devices. 4) Independent verification by ARB (California Air Resource Board)

Airgle's AG600/AG900 devices are available with and without a UV module. The devices without a UV module comply with the Bavarian funding guidelines, but can easily be retrofitted with the Titanium-Pro module at any time.

Yes, UVC light is harmful when it comes in direct contact with the skin or eyes. BUT: The UV light sources are securely installed inside the Airgle devices and are therefore considered harmless according to the Environmental Protection Agency (see also statement UV light harmlessness). In addition, the device switches off as soon as the housing is opened. This prevents damage to the skin and eyes from the UV light. In addition, Airgle has passed safety tests that verify UV safety; such as: ETL/UL 507/867 standard, CE/CB, the Japanese PSE, the Korean KC/CA and "China Safety". A current study by Prof. Dr. Plischke from the Munich University of Applied Sciences, who confirms the effectiveness of UV-C rays with regard to the inactivation of corona viruses (https://www.br.de/nachrichten/bayern/professor-beckt-uv-c-geraet-vernichtet-coronaviren ,SHNvcKJ).

What are the benefits of air purifiers? Even after the corona pandemic, air purifiers offer a wide range of advantages:Filter allergens from the air and are therefore ideal for allergy sufferersSickness rate is reduced because a large number of germs in the air are significantly reducedLess (fine) dust in the airWell BeingIncreased performance through better room air climatePrevention of sick building syndromeAdded value for employees and customersReduced VOC pollutiono Further information on VOCs can be found at: https://www.bmu.de/themen/gesundheit-chemikalien/gesundheit-und- welt/innenraumluft/fluechtige-organische-verbindungen/
