I have used their Aroma Beam and Aroma One, and both provide highly effective odor control and air freshening in smaller or larger spaces. They only use the highest quality essential oils in their fragrance refills and their products contain a true odor neutralizing additive, Metazene. Most other scenting companies in the South FL area claim they have odor controlling properties, but they only mask odors. Air-Scent Services; products kill the vaporous odors at their molecular level, so there is no masking. Highly recommend their products for any condominium or commercial interior space.
