Which Filter For acoustic 12" 4250 m3/hr

Hi Everyone well i am currently confused regarding filter size to go with my fan i have got..

I have an acoustic 12" box fan 4250m3/hr but every filter i look at is rated approx 1500m3/hr

bearing in mind i have 1 inlet & 1 outlet, should i get a splitter to say 2 x 10" & attach them to 2 10" carbon filters approx 2000m3/hr each to give it the same airflow.

I do not want to have a more powerful fan than what the filters can take...

and if i was to have 2 filters i can mount them in 2 different locations in the room.

What do you think?

thanks in advance.
