Well, he went as far as confirming he was getting the same particle counts.
He confirmed that the homemade filter reduced particle counts. But I don't see that he compared its effectiveness to filters costing "up to $1000".

Compares Blue Air 203/270E (3,600 RMB) and a Philips AC4072 (3, 000 RMB) to both of his setups. Those are only about $550 filters, but I think that is sufficient to cover the "up to" in "up to $1000". If you want to donate a $1000 one to him, it looks like he'd be happy to test it.
