Air cleanliness is classified according to the number and size of particles within a sample of air, measured in particles per cubic foot or cubic meter of air. The European Union Tissues and Cells Directive has now made a requirement for IVF laboratories to ensure that certain air quality standards are met. Esco Medical IVF workstation, Fertilisafe or biosafety cabinet which embryologist work with gametes or embryos meet an air quality of the highest standard.
High efficiency particulate air (HEPA) filters remove particles smaller than 0.3 µm. Filters to remove volatile organic compounds (VOC – large group of carbon-based chemicals that easily evaporate at room temperature), which could potentially jeopardize embryo culture procedure. It has been known that the air quality in IVF laboratory can have higher levels of VOCs than outdoor environment air. The impact of VOC on embryo culture will significantly affect on embryo cleavage rate, embryo development and blastocyst formation rate.
