Why there is musty smell from library books

Release time:2020-12-18 09:27:26    


One day while walking around the library, you spot a book that you used to love 20 years ago. Memories come back to you; you smile, your eyes shine... A strong desire to read it all over again builds up. You take it out of the shelf and flip through the pages. Then, all of a sudden you feel repelled as if someone had put it under a magic spell to prevent you from reading it. Your strong desire goes away… you take a step back with your head down. It’s that musty smell. Yes, smells can affect our mood and experiences.

The mysterious books had some strange colors on their pages and we couldn't stand their smell: that musty smell. Somehow, it was a warning of potential danger. Not wanting to, we were forced to throw all of them away. They’d probably be worth thousands of dollars nowadays, or they could’ve meant unforgettable moments glancing through their pages. But odor won the battle. Why do books smell musty? 

According to the Centers for Disease Control and Prevention (CDC), “Mold grows well on paper products, cardboard, ceiling tiles, and wood products. Mold can also grow in dust, paints, wallpaper, insulation, drywall, carpet, fabric, and upholstery.”  So, there’s the answer: Paper and fabrics (some book covers have fabrics) are one of mold’s favorite foods!

That could be one of the reasons why your books smell musty. That funky smell comes from mold. And why do mold colonies tend to grow more in some libraries than in others?

These are some factors that can increase the chances of mold showing up in yours:

Darkness: Mold colonies are afraid of sunlight.

Warm temperatures: They love heat and grow better when it’s warm around.

High moisture: They need high indoor relative humidity levels to survive.

Food supplies: Mold colonies grow where they find food. Some of their favorite foods are leather, cloth, paper, wallpaper, and wood. 

Calm still air: Mold loves it when the air is still and calm.

Dusty surfaces: Mold finds dusty surfaces very attractive. 


LIVA book sterilizer-Protecting readers and staff from health issues

Library is a treasure of history and knowledge. We all like to visit libraries in our school days. However, the musty smell from the books is unbearable. Libraries have come up with various ways to deal with the dust on the surface. But the simple cleaning is hardly sastifactory.

In order to create a better reading environment, Evertree developed LIVA self-service book sterilizer. LIVA book sterilizer applies UV-C lamps and a fan to remove the dust and other pathogens on books. As UV-C has extremely low penetration, the pages have to be exposed to the UV-C radiation. LIVA book sterilizer opens the books gently with the air stream and the inner parts of the books can also be disinfected. Meanwhile, the dust and other residues can also be eliminated. With ten years efforts, the researchers have extended the lifespan of the book sterilizer to 30,000 times on/off. We guarantee that the lifetime can at least reach 15000 times on/off.
