VGrow Vivosun has an awful filtration.

Hope you will find this model useful.

This model is designed for 2 mm sealing tape or foam rubber on each side.

Materials:
HEPA Paper - H10 up to H14
Active Charcoal - 1 kg
Sealing Tape or Rubber Foam 2mm - 1 - 2 meters?

Notes:
H14 Hepa Paper is probably too much
Active Charcoal should be small, diameter of the hexagons is 1 cm.
Termo Glue is probably best, don’t causing chemical smell.
