Seem to be authentic
Items ordered were Sold by CPAP Miami and Fulfilled by Amazon.<br /><br />Items seem to be authentic. I cannot test at this time since I just installed my last remaining "pollen filter", so I ordered these. Thus, I cannot feasibly waste that one in order to test these. But if there is a problem, I will certainly update this review. Arrived in the time listed by Amazon.
