The porous material is evenly saturated with water and traps large and small particles of dirt. After a short initial period, cleaning bacteria provide intense biological decomposition of harmful substances, colonizing the specially structured foam. The fine and coarse filters can be reused many times. To clean them, simply rinse and squeeze out, so the bacterial cultures are not completely destroyed.
