Eco 420 Personal Air Filter Kit
This personal air filter by Eco Four Twenty is so easy to use, simply exhale smoke through this device to reduce harmful second-hand smoke and odour that can affect your roommates, family and neighbours.
This device's casing is made of high-quality aircraft grade aluminium and 2 stage medical grade filter. It lasts up to 500 exhales, AND instead of buying a whole new filter you'll only have to replace it with another Eco Four Twenty filter cartridge.
Backed by Eco Four Twenty's Lifetime Warranty and their 100% satisfaction guarantee, you will not be disappointed.
