How to remove moisture: effective solutions

How to remove moisture? Discover condensation and adsorption solutions and our advice for choosing the right method for your space.

The two methods for removing moisture

To extract the humidity present in the air, two technical approaches exist: Condensation and adsorption. The choice depends mainly on the volume of air to be treated and the constraints of the place.

Condensation dehumidification

This technique consists in bringing the air into contact with a cold surface.
The water it contains then condenses into droplets that flow into a tank to be emptied regularly.

How it works

  • The air passes through a cold exchanger.

  • Water vapor is transformed into liquid.

  • The collected water is evacuated via a tray or pipe.

This is the principle used by electric dehumidifiers, suitable for spaces such as cellars, garages or humid rooms, provided there is an electrical supply.

Dehumidification by adsorption

In this method, adsorbent materials are placed directly in the space to be protected. They capture water thanks to their internal pores.

Examples of adsorbent materials

  • Silica gel : present in the small bags of electronic boxes.

  • Salt tablets : they liquefy and form a brine to be evacuated.

  • Air Sponge : durable adsorbent solution based on mesoporous material.

As the adsorption capacity is limited, some products require regular replacement or regeneration.

How do you choose the right solution?

For an entire room

If you need to treat a large volume (cellar, garage, container...), a condensation dehumidifier can be used when an electrical outlet is available.
However, This type of device consumes energy, which can be a constraint in prolonged use.

On the other hand, Air Sponge works without electricity thanks to its adsorbent mesoporous material. It regulates humidity passively, without noise, without maintenance and without energy costs, unlike electrical systems or salts that become saturated and must be replaced.

For storage containers

Humidity in containers often comes from Condensation on the ceiling, which generates drops, runoff and risks of corrosion.
Thanks to its patented mesoporous material, Air Sponge adsorbs moisture as soon as the level exceeds about 60%, then releases it naturally when the air dries out, thus avoiding saturation.

Its flexible format (tape, adhesive or magnetic application depending on the model) allows it to adapt to the container wall, where moisture forms. This adaptability makes it a particularly effective solution compared to conventional desiccants.

For a box or a small volume

In small storage boxes, silica gel may work, but it needs to be replaced as soon as it is saturated. Air Sponge offers a more sustainable alternative, because it regenerates naturally without intervention and continues to adsorb moisture without creating waste. Its installation is simple and allows continuous action over time.

Air Sponge: a more sustainable solution than conventional desiccants

Unlike salt tablets that liquefy or silica gel bags that need to be replaced, Air Sponge uses mesoporous material capable of adsorbing and then naturally releasing moisture when the air dries up. It works without electricity, produces no waste and remains effective over time, making it a powerful alternative for containers, garages or closed storage spaces.
