While you might think a five-star hotel would have the cleanest rooms, that’s not necessarily the case.
Trip calculator site Travelmath recently teamed up with air-quality experts EmLab P&K to analyse 36 different samples that were taken from nine different hotels varying in quality from three stars to five stars.
The team at EmLab P&K counted the total number of Colony Forming Unit (CFU), which are essentially units used to estimate the number of bacteria, yeast, and mould cultures from a given sample, per square inch of each hotel room.
The results showed that the average hotel room is dirtier than a typical home, school, or aeroplane, and that for some tested surfaces, five-star hotels had a much higher CFU count than three-star or four-star hotels.
It’s important to note that results could vary between hotels, and Travelmath didn’t disclose the names of the nine hotels they visited.
