Marko carries a variety of hospital/commercial grade deodorizers and disinfectants. In general, they outlast household products many times over, plus cover larger areas. This means savings! “Nasal fatigue” is a term used when a fragrance can no longer be noticed by a person, yet the fragrance is still present in the air. It happens to everyone, to differing degrees and is why the air freshener and fragrance industry is so subjective. To reduce the effect of nasal fatigue, we recommend changing the fragrances of the air fresheners and deodorizers you’re using every month.
