General guidelines
Based on network equipment environmental criteria, telecommunications industry standards, thermal management concerns,
and fiscal assessments, it is recommended air filters are to be replaced every three to six months, or within the recommended
preventive maintenance schedule.
Storing air filters for more than 6 months is not recommended. Instead, purchase cost-effective quantities and keep sufficient
inventories based on your replacement cycle. Telecom air filters have improved permanence (service life) in an operating
situation with air movement and ventilation.
NOTE: To maintain optimal system health, Dell Technologies recommends checking and changing the filter every three
months. Filters can be ordered from Dell.
