Assuming you have a detection limit (lowest activity you can measure to a predetermined confidence level) of 20 Bq on you filter measuring system, how much air would you have to sample through your filter to be able to detect the naturally occurring concentration of Po-210 (assuming UNSCEAR values)? Assume that your filter has 100% sampling efficiency for Po-210, and that your sampling system can discriminate perfectly between Po-210 alphas and other radionuclide decay emissions.
