Yes. During its Halloween Scary Good Deals, which the shop dates 23 October to 1 November, Airthereal shows two codes on its sale page. One gives 20% off selected purifiers and vacuums, taking the Zephyr AZH200 from $99.99 to $79.99 and the T1 Touchless Vacuum from $159.99 to $127.99. The other gives 10% off selected ozone generators, so the MA10K-PRO falls from $109.99 to $98.99. Other items carry sale prices, such as the DA25 Desktop Ozone Generator at $59.99 instead of $79.99. Ozone generators cannot be shipped to California.
