Safe Air Systems, Inc. has been a dealer for Lawrence Factor for nearly two decades.  We stock a wide variety of  X-pendable Purification Cartridges in our warehouse and can generally ship to you same day.

We provide Air Quality Testing that is simple to administer, through Lawrence Factor’s X-zam Laboratories, with results returning within a week.  Many testing programs are available to suit your needs.  All components of the test are shipped to you via UPS and return labels are supplied with each kit to facilitate easy return to the lab.  If at anytime, your sample does not pass, we will ship you a retest kit immediately at no extra charge and have one of our service technicians call to troubleshoot the cause of the failed test.
