   We can use `dplyr::filter` with `dplyr::across` for this use case.
   
   ``` r
   df <- data.frame(a = 1:3, b = c("a", NA, "c"))
   
   df |>
     arrow::as_arrow_table() |>
     dplyr::filter(dplyr::across(everything(), ~ !is.na(.))) |>
     dplyr::collect()
   #>   a b
   #> 1 1 a
   #> 2 3 c
   ```

   Note that this is why dbplyr does not implement drop_na either. tidyverse/dbplyr#999
