Personal Air Filter

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 odor that can affect your roommates, family, and neighbors. This device's casing is made of high-quality aircraft-grade aluminum and 2 stages 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. ***You will not be disappointed if you are backed by Eco Four Twenty's Lifetime Warranty and their 100% satisfaction guarantee***
