Universal filter for aspirator 47 x 57 cm, carbon wool, with indicator, A03

Universal filter for aspirator A03 of the NITEC brand, made of carbon wool. The product contains more than 40% activated carbon and perfectly absorbs fats and odors. Special impregnation makes it non-flammable and chemically neutral (pH = 7).
The aspirator filter has a saturation indicator: when saturated and soaked with fat, the gray stripes change color to red/brown and thus indicate the time when it is necessary to change it.
The filter measures 47 x 57 cm and is suitable for all aspirators up to 60 cm wide.
