For those asking what the price is for ionic smokeless ashtray at Walmart, I regretly inform you that Walmart does not seem to carry any smokeless ashtrays, at least not on their online store. I’m not sure if they’re selling it on their actual stores but I couldn’t find any on the one near my place. Walmart is, however, selling replacement filters for the Holmes Smokeless Ashtray but NOT ionic smokeless ashtray filters. You’ll probably need to go order them at Amazon.
Here is a picture of the filter they’re selling at Walmart.
