Cleanxa was conceived to not only keep you safe and secure, but as a way to reach out and say "thank you" to the real heroes serving us all and risking their own health and safety while in the course of their duties. If you work in the law enforcement community or firehouse, work as a first responder or serve others in the health care industries and nursing homes, we are recognizing your efforts by giving you a free mask. Simply add your 'free mask' to your shopping cart - continue shopping for other items of need (like extra filter refills), and then enter your discount code (free-msk-deal) during the checkout process. The only thing we ask you to pay for is shipping & handling. THANK YOU FROM CLEANXA!
