Branch Basics on Instagram: "The Easiest, Most Affordable DIY Air Purifier!⁠ ⁠ 1. Get a 20 x 20 box fan⁠ 2. Get a 20 x 20 @Filtrete Filter*⁠ 3. Start the fan⁠ 4. Suction the filter to the back of the fan⁠. (Tape on if you want filter to stay on when fan is off.) ⁠ * Look for Merv 11, 12, 13, or 14 on the filter. You want a high Merv rating that will still allow air to flow through.⁠ ⁠ Have any questions? Ask away! 🤗"
