After 60+ hours of research & testing, we’re comfortable recommending the Fresh Wave Odor Remover as the best cigarette smoke eliminator spray on the market (as of summer 2019) due to its activation speed, scent options & EPA approved ingredients. With that said, for those looking for a more permanent & on-going solution, we highly recommend the Pure Enrichment PureZone HEPA Air Purifier for its effectiveness (99.97% capture rate held up in our tests), quietness & versatility.
