It must have been enough since his sperm count increased 4x, no?
Either the filter worked or microplastics don't effect sperm count much.

“Something changed, therefore this must be the reason” is a fallacy if there isn’t additional supporting evidence.
That said. If I lived in a village that was attacked by tigers regularly for 6 months, and I installed a tiger filter which stopped the attacks, I would gladly pay 30 bucks for that ($30 is what a faucet water filter costs).
Disclaimer: I don't own a water filter or a tiger filter.
