In cases of water damage, mold occurs as early as a couple of days after the damage begins. When drying microbial growth structures, so many microbial cells and other substances / ingredients that are hazardous to human health are released into the air that living or working continuously in rooms to be dried is not desirable for health reasons. As a result of irreparable moisture damage, microbial growth can form in the structures, from which microbial cells such as spores can detach. These spores travel to the indoor air with air currents. People indoors can be exposed to these spores. Typical symptoms caused by exposure include eye, skin and respiratory symptoms, recurrent respiratory infections and allergic diseases. The health risk of exposure is high, for example, in hospitals where the consequences can be very severe in immunocompromised patients or otherwise debilitated individuals. Children are also at particular risk when they are exposed to high levels of microbes, for example in connection with moisture and mold damage repairs in residential buildings and kindergartens, which can result in very serious respiratory diseases. During repair work on moisture and mold damage, the microbial concentrations in the indoor air increase considerably. A LIFA DRY & CLEAN unit has been developed for water damage drying and safe repair of moisture and mold damage, which simultaneously dries the air and cleans it of particulate contaminants (such as microbes) and gaseous contaminants (such as microbial metabolites (MVOC)). Numerous scientific research results have been published on the device and its functionality, together with the material published at the HB2000 Healthy Building Conference. The technical data of the device are attached.
In Finland, the Tekes Terve Talo program includes a "Clean and functional ventilation" technology project, in which measurements were made of the dust content of ventilation ducts before and after the cleaning work, both in practical conditions and in the laboratory. The studies have objectively compared different cleaning methods, machines and equipment, as well as tools needed at work, such as cleaning brushes. From the studies, it is easy to conclude that Lifa Air’s duct cleaning equipment was overwhelmingly efficient. Numerous scientific research results have been published on the devices and their functionality, e.g. Timo Jalonen: Efficiency of air duct cleaning methods. In addition, material on "Cleaning and Inspection of Air Conditioning Equipment" has been published at the HB2000 Healthy Building Conference.
Yes. Lifa Air has developed a method for inspecting a ventilation duct with a robotic camera. If a visual cleaning method is used, a separate review of quality control is not required. Lifa Air has developed and patented the Hydmaster cleaning device, which records the entire cleaning work process. During the cleaning work, the contractor is able to control the quality of his work and, if necessary, immediately clean the poorly cleaned area. This avoids a bad work pattern and is able to record the entire cleaning work process without a separate quality control recording. In addition to cost savings, increased customer satisfaction must be taken into account, in which case the person who ordered the work will receive a video describing the entire cleaning work and the post-work in connection with the invoice. In this case, the customer can trust the result and pay the agreed compensation to the contractor.
Machine and equipment manufacturers should always ensure that equipment users receive the necessary training package for cleaning ventilation ducts. It is easy to suspect the spread of dust accumulated above the ventilation ducts during cleaning work, primarily as a reason for the spread of dust. The ducts to be cleaned should therefore be cleaned first on the outside and only then on the inside. The use of compressors indoors should refer to the use of equipment solutions where the force rotated by the brush or other cleaning tool is compressed air. Compressors should be selected according to the application so that they do not unnecessarily disturb outsiders. The best compressor option in terms of sound and power ratio is the lamella compressor. Alternatively, the cleaning work can be carried out efficiently and almost silently with Lifa Air's patented Hydmaster, which will be the number one choice for contractors performing professional IV cleaning work.
