DIY dehumidifier: instructions for preparing anatural dehumidifier do-it-yourselfto be used in rooms up to 50 square meters. All advice.
Those who live in a coastal area, in a country house or in a rainy area will certainly have to deal with humidity, especially in autumn and winter. Even those who have a home with problems of infiltration, condensation, thermal bridges and bad insulation can easily be a victim of humidity. In these circumstances it is advisable to do a building intervention in order to improve the thermal performance of the building and home comfort.
Let's assume that aDIY dehumidifierit can only be effective in small rooms such as closets, wardrobes and bedrooms with a maximum surface area of 50 square meters where a salt solution of at least one kg is used.
To prepare a DIY dehumitifier for closets or closets you will need the following material. As the environment givesdehumidifygets bigger, increase the dosage ofcalcium chlorideor, even better, prepare several DIY devices to place in the corners of the da areadehumidify. Here's what it takes to prepare anatural dehumidifier do it yourself:
- A sock
- 300 gr of calcium chloride
- Large enough plastic bowl or saucepan
- Wooden batten
Thecalcium chlorideit is a high power salthygroscopic, this means that it is able to capture the water found in the environment in the form ofhumidity. It is very soluble in water therefore, gradually as yoursdiy dehumifierit will capture the water present in the room air, it will be consumed by dissolving in the same humidity it has collected.
Calcium chloride is not expensive at all, one kg is offered on Amazon at a price of 7.99 euros with free shipping. For more information on how the product looks or how to purchase, please refer to the official page: Calcium chloride for DIY dehumidifier.
To regenerate theDIY dehumidifier, do not come to mind the brilliant idea of recovering the salt by evaporation of the water. In theory this idea is feasible but in practical terms it is not: calcium chloride, at high temperatures, becomes corrosive ... in other words, you cannot put it in the oven as you do to recycle the "dehumidifying balls" in silica gel (for insights:how to reuse silicon sachets).
DIY dehumidifier - How to proceed
- Take a men's sock and fill it with calcium chloride (if you bought calcium chloride in the form of a bar, break it as well, taking care to use dry gloves to handle the calcium chloride).
- The sock must be filled with calcium chloride but must allow it to close. Knot the end of the sock to close the calcium salt inside.
- Take a piece of wood that is long enough to stick to the edges of the pot or plastic container.
- Hook the sock to the wooden strip and keep it suspended in the pot.
DIY dehumidifier for drawers, sideboards and cabinets
Fordehumidify drawers, shoe racks, bedside tables or sideboards, we recommend purchasing the most practical (and original) sachets of silica gel. As mentioned above, these sachets are reusable. The sachets remove moisture from the air but one is not enough. To fully exploit the power of silica gel it will be necessary to buy a small batch and use them in groups of 3 - 5 or 10, depending on the size of the drawer to be dehumidify. Silica gel prices vary a lot based on quantity, quality and manufacturer's warranty. What makes the difference is the wrapping, in fact this is what allows you to reuse the same sachets over and over again. A sealed bottle of100 sachets of silica gel(2 gram micro bag, as well as the size of the classic sachets that we find among newly bought sweatshirts and shoes) is offered on Amazon at a price of 38 euros. Those who want to save on the purchase can choose 100 sachets of 1 gram at a price of about 12 euros. To regenerate the anti-humidity power of the silica-gel sachets, just put them in a ventilated oven at 110 ° C over the time and in the manner prescribed by the manufacturer.
