DESCRIPTION OF THE STUDY: Title: EVALUATION OF BIOCIDAL ACTIVITY OF THE AIR PURIFYING DEVICE: AIRLIFE (AirLife Swiss) Internal reference: AIRLIFE SWISS AG Dorfstrasse 38, 6340, Baar, Switzerland Contact: Kharis MUSALEEV Test period: Study manager: Inès BEAUGELIN Anna BEHR and Meryl JOANINA Test laboratory : Laboratoire EUROFINS BIOTECH – GERMANDE 505 rue Louis Berton Bâtiment 2 13290 Aix en Provence, FRANCE II. OBJECTIVE OF THE STUDY: Evaluate, according to an internal protocol, the capacity of the Photocatalytic Air Purifier SA-100 (Airlife Swiss AG) to reduce...

EUROFINS BIOTECH-GERMANDE IV. METHOD: a) Tested strain: Staphylococcus aureus ATCC 6538 Micrococcus luteus ATCC 10240 Aspergillus brasiliensis ATCC 16404 The conditions of preservation and control of the microbial strains used for the determination of the bactericidal activity are those described in the European standard NF EN 12353(1) (internal protocol: T-DM-S-WO37879). b) Neutralizing solution: Composition of the neutralizing solution: Tween 80:.……………………………………….… Sodium thiosulfate:……………………………. Tryptone soya broth:………………………….. Steam sterilized (121°C, 21 minutes). Internal reference:...

EUROFINS BIOTECH-GERMANDE Two devices were used in order to assess the bactericidal and fungidical activities of the Photocatalytic Air Purifier SA-100. The “negative control” device contains the air flow system without the photocatalytic and the filter unit. In comparison, the assay device required both the photocatalytic and filter unit. A comparison between the two devices will allow to calculate a microbial charge reduction. f) Conditions of use of the device : The two devices where placed in two separted laminar flow (85HOT003 and 85HOT004 for Aspergillus brasiliensis and 85HOT008 and...

EUROFINS BIOTECH-GERMANDE V. RESULTS: Table 1: Results. Evaluation of bactericidal activity of PHOTOCATALYTIC AIR PURIFIER SA-100 process against Staphylococcus aureus. N.A: non applicable. Logarithmic and percentage reduction are obtained by subtract the number of viable and countable microorganisms to the number of microbes recovered in the negative control test. Negative control (level Microbial of contamination on the test output) Nb suspension CFU/sampled area (Log (Nb. CFU/ml) value) 1.8 104 (4.2) Logarithmic Percentage reduction reduction Filter area 3 Mean values of filter areas...

EUROFINS BIOTECH-GERMANDE VI. CONCLUSIONS: In the test conditions described, the process PHOTOCATALYTIC AIR PURIFIER SA-100 induces a reduction of the number of viable cells of Staphylococcus aureus ATCC 6538 spread inside and passed through the air purifying column of 99.98%. It also induces a mean reduction of the number of viable and cultivable cells of Staphylococcus aureus ATCC 6538 of 99.98% trapped inside the photocatalytic and filter device. In the test conditions described, the process PHOTOCATALYTIC AIR PURIFIER SA-100 induces a reduction of the number of viable cells of...
