The Small Bathroom Fix That Improves Air Quality

Following a bath, moisture collects on tiles, mirrors, and other surfaces, sometimes even hours after the bathing area has been left untouched. The presence of moisture makes for a perfect environment for molds to grow, especially since bathrooms usually have low air circulation. Solving the issue involves not just cleaning up the mess.

According to the studies published by PubMed, substances like calcium chloride and silica gel absorb the moisture from the atmosphere to minimize the level of humidity in the surrounding air. As such, they contribute significantly to preventing the development of molds since they reduce the moisture content in the air immediately.

How does absorption change indoor conditions?

Water-attracting substances act by pulling and retaining water vapor present in the air. Scientific literature accessed via ScienceDirect demonstrates that lower relative humidity indoors directly impacts the growth of microorganisms and prevents the occurrence of surface condensation.


This becomes significant in bathrooms because the repetitive presence of steam ensures continuous moisture accumulation. Absorbers prevent the creation of a favorable environment for fungi and molds to grow by decreasing humidity levels. The success of this strategy hinges on positioning, which becomes highly effective when used close to shower stalls and other confined locations.

Despite their limitations, absorbers are a supplementary measure that can help enhance the performance of ventilation systems.

Can you combine methods for better results?

Humidity management is highly effective when different approaches are combined. The ventilation process helps get rid of the moisture in the atmosphere, whereas absorption is applied to manage any excess humidity remaining in the room even after the atmosphere becomes steady. Studies indicate that this combination leads to a much better state inside the room than when applied separately.

Absorption media also have certain weaknesses since they cannot be used in extremely humid rooms. Minor changes in moisture control could make a huge difference for your room's atmosphere.
