The newest line of innovative Elima-Draft products is here! Our Commercial Filtration Cover provides a last line of defense against harmful particles coming through commercial diffusers. The cover attaches magnetically to drop-ceiling tracks (or the diffuser itself if no tracks) for ease of installation and filter changing. The cover is ideal for office spaces, medical settings, restaurants and boutiques, in that it virtually eliminates harmful dust, pollen and even mold spores! Breathe easier! Your customers and coworkers will thank you for it!
