Assembly Options

Choose the option that works best for you:

Pre-Assembled Fan Panel – Fans arrive installed, so you only need to assemble the Brisk Box with your filters.

DIY Fan Assembly Kit – Save $20 by assembling the fan panel yourself using the included hardware.

Assembly typically takes less than 10 minutes using the included instructions.

Filter Options

The Brisk Box uses four 1-inch filters, which are sold separately.

 Choose the compatible filter size that works best for your setup.

For a more compact square configuration, the Brisk Box can also be assembled using two 10 × 20 × 1 filters and two 12 × 20 × 1 filters by trimming the included coroplast panel.
