After formaldehyde-chamber-disinfection of respirators considerable quantities of formaldehyde deposit (presumably deep adsorption) within the devices. When the apparatuses are re-employed the respired air contains more than 1,000 (in individual cases more than 4,000) micrograms/m3. Thus all limits are exceeded by far. The liberation of the formaldehyde deposited in considerable amounts comes off according to an exponential equation dependent on the time of employment slowly, that with following chamber disinfections the quantities of formaldehyde in the apparatuses are still increased and still higher loadings of the respired gas occur. Even after employing them for a long time either non-stop or intermittently "saturated" respirators can not be used again. The disinfection according to the principle of the Aseptor-chamber or its imitations has to be refused for respirators and similar medical technical devices, e.g. incubators.
对呼吸器进行甲醛箱式消毒后，大量甲醛沉积在设备内部（可能是深度吸附）。当再次使用这些设备时，呼出的空气中甲醛含量超过1000微克/立方米（个别情况下超过4000微克/立方米）。因此，远远超出了所有限值。大量沉积的甲醛会按照指数方程缓慢释放，这取决于使用时间，随着后续的箱式消毒，设备中的甲醛量仍会增加，呼出气体的负荷也会更高。即使长时间不间断或间歇性使用后，“饱和”的呼吸器也不能再次使用。对于呼吸器和类似的医疗技术设备，如孵化器，必须拒绝采用Aseptor箱式原理或其仿制品进行消毒。
