The reason I buy all my CPAP supplies from EasyBreathe instead of getting them from my HMO here in California is that my HMO's facilities, and therefore everything in them, are permeated with fragrance, and everything I've bought from EasyBreathe to date has been responsibly handled and warehoused and thus fragrance free.
This shipment of two ESON replacement head straps was different. Each of the two units had a fragrance smell, the two subtly different from each other, as if they'd been stored in an Amazon warehouse, but in separate locations.
By the time I realized it was the straps themselves and not the bags, the packing materials were gone and the straps had been laundered, so not returnable. Sigh. I'll just keep laundering until usable, probably costing half the useful life. Being super fragrance sensitive (asthma and other) gets old.
EasyBreathe is better than sending shopworn product, and I trust it will never happen again.
