When people smoke in cars, tar residue sticks to surfaces like the windows, which builds up over time, leaving a brown film
A unit with True HEPA and substantial activated carbon (at least 12 lbs pelletized) will capture smoke particles and adsorb many of the VOCs and odors
No, a regular filter is not effective for smoke
Prices vary by material, finish, and order size, but heres a simple starting picture: Basic kraft or cardboard boxes: lowest cost, great for testing Printed paperboard with lamination: mid-range, the most popular choice Rigid boxes with embossing and foil: highest cost, highest perceived value Bigger orders always lower the price per box
We appreciate every donation
The small flip-top boxes are used by regular brands
