Hi all, first time poster. Found this filter finally on offer after almost a year. Not historically cheapest of $540 (Ozbargain history), but $589 is not too far off considering the surge in demand in the last 8 months. Same price is also listed on Kogan and appliance online.

Prices on ebay was the same $589 delivered last night (28th June), but prices went up to mid $600s this morning (29th June).
What's the cost for replacement filter?
