Please kindly be noted that per the manufacturer’s recommendation of the compounded filters replacement per year, the average annual replacement cost would be RMB 3,830, in lieu of RMB 1,300 – i.e. the difference of RMB 2, 530, which should be inclusive in the CR. Of course, if the indicative cost of RMB 1,300 can cover all filters after confirmed by the vendor, then this would be the incurred amount. Having said that the usual practice for total cost of drinking machines should include the replacement cost per the recommended frequencies for water quality assurance. Hope the above clarifies.
