Store in a cool and dry place away from direct sunlight. Ambient temperature should be kept between 5℃ and 35℃; avoid direct sunlight, dampness and frost.

Keep original factory packaging intact. Do not stack filter elements under heavy pressure or pile them too high; avoid long-term bare exposure without packaging.

For rubber sealing gaskets and filter cartridges, follow the FIFO rule (First In First Out) based on production dates. Do not stock parts for excessively long periods beyond their shelf life.
