Yle News – Use of air purifiers at two daycare centres in Helsinki led to a reduction in illnesses and absences among children and staff, according to preliminary findings of a new study led by E3 Pandemic Response.
Air purifiers of various sizes and types were placed in two of the city’s daycare centres during cold and flu seasons. The initial results from the first year of research are promising, according to researcher Enni Sanmark, from HUS Helsinki University Hospital.
“Children were clearly less sick in daycare centres where air purification devices were used — down by around 30 percent,” Sanmark explained.
The air purifiers were changed at two daycare centres serving as a control in the experiment, in order to rule out the effect that possible epidemic fluctuations could have on the results. The study’s next phase will continue until April.
“We will be able to analyse whether there were only decreases in flu-type illnesses or whether the use of air purification could also help reduce stomach ailments,” Sanmark said. On average, daycare centre-aged children suffer 10-13 infectious illnesses every year, with each illness lasting from one to three weeks, according to the research …
“It would be a big savings if we could get rid of 30 percent of sick days spread by children, as well as the illnesses that go home to parents.”
Water-bath filtration
A water-bath filtration system uses water as an air filter, trapping dirt, dust, and allergens in the water. The system forces the air through a water-bath. A specially designed separator separates the air from water so only clean, fresh, water-washed air is returned.
This design ensures superior air flow consistency and filtration efficiency.
In comparison: Conventional filters, micro filters, and electrically charged filters used in most air purifiers or vacuum cleaners allow small particles to pass right through the filter and re-circulate back into the air we breathe.
Furthermore, filters become clogged with the particles trapped after a short period of usage, causing restricted airflow, and consequently a loss of performance.
What nature does outside – self-purification of air with water – water-bath filtration can accomplish inside your home.
