Done! You've created an effective DIY dehumidifier. It's simple, fast, and proven to work in real homes.
Combat bedroom humidity naturally, or use it in closets and verandas. It traps moisture, cleans the air, and prevents wall dampness—all with natural, budget-friendly materials.
No need for expensive store-bought options from Boulanger, Leroy Merlin, or Walmart like Delonghi, Dyson, or Rubson. This version is silent, compact, portable, and ideal for small apartments.
If you're out of lavender oil, you can find some here.
Coarse salt is a powerful natural desiccant, absorbing humidity from the air just like in commercial units. Moisture collects on the salt, drips through to the cotton below, which holds the water.
Lavender essential oil adds purifying and calming benefits with a fresh scent.
- Empty collected water regularly.
- Replace salt every 15 days.
- Ventilate your home twice daily for 20 minutes.
- Inspect walls for damage.
