Demonstration of the suppression against Moraxella bacterium Bacillus (causative agent of the laundry's damp odor)
Testing organization
Japan Food Research Laboratories
Test method
A sample containing 2 ml of the test bacterial solution in a petri dish (φ60 mm) was left to stand in the Streamer generator. The suppression effect was obtained from the results of measuring the number of bacteria after 1, 2, 3, 4, and 6 hours. The Streamer discharge device and test bacteria were provided by Daikin. This was measured 3 times
As a result of the test, it was confirmed that Moraxella bacterium (causative agent of the laundry's damp odor) was decomposed and suppressed by 99.8% in 2 hours after the Streamer irradiation.
* The results are obtained from demonstration of solely the Daikin Streamer discharge device in an experimental condition.
To eliminate musty smells from laundry, it's best to dry it within 5 hours.
The most important factor in preventing musty odors is the time between washing and drying. Moraxella bacteria grow exponentially after about 5 hours, so drying within that timeframe can significantly reduce the musty smell. Here's a trick for drying clothes indoors. First, it's important to hang them in a well-ventilated area. Many people hang their clothes on curtain rods, but this is the worst option because moisture can easily accumulate on the window, and it also harbors many germs.
And we've also come up with a way to dry them properly. Clothes can be dried quickly by hanging the longest garment on the outermost hanger, using the "arc drying" method by hanging the shortest garment in the middle, or the "ghost drying" method by placing only the sleeves of a shirt on another hanger. Considering the potential for bacterial growth, it's recommended to use a dehumidifier or an air conditioning system with an air purification function. If you're worried about odors, try this method, as the musty smell of laundry can be eliminated with a small effort like this.
