Monsoons, dampness, and the quest for moisture absorbents

I'm going to be away from home for a fortnight. Like any Mumbai resident, I'm less worried about missing home than what those two weeks in the monsoon will do to my closets.

I'm already imagining coming back to mold-laden clothes, the smell of dampness from every corner, the creeping horror of discovering one odd item after another has caught the bug. The inevitable ritual of washing everything, only for it to refuse to dry because of the very monsoon that caused the problem in the first place.

As a preventive measure, I've been hunting for moisture absorbents across e- and q-commerce apps, only to find them unavailable or out of stock everywhere. The strange thing about this scarcity is that nobody seems to be complaining about it. Moisture absorbents don't occupy the same prestige mindspace as Diet Coke, I reckon.

I don't remember who first introduced me to moisture absorbents, but I've been using them for roughly a decade. I grew up in north India, where dampness wasn't really something you planned your life around. When I first moved to Mumbai 16 years ago, I tackled moisture the only way I knew: naphthalene balls, tucked into cupboards the way we'd store winter woollens back home to keep insects away.

Sublimation vs Fusion

Moisture absorbent products work on an entirely different principle. Instead of sublimation—the solid slowly disappearing into gas—they rely on fusion. The silica gel beads slowly melt into liquid over the course of the monsoon. You can actually see them working, protecting your belongings.

It’s a product category that’s evolved. First came bulky plastic boxes that looked like miniature two-storeyed houses, with silica crystals upstairs and the liquid collecting below a month later. Then came compact pouches, almost like ice packs, whose beads transformed into a gelatinous mass. I stopped trusting those after a friend said one had burst in her bedroom, ruining her upholstery more effectively than moisture ever could. Eventually I found hanging pouches that borrowed the old two-compartment design in a more compact format.

These products have also steadily become pricier, with brands that make living-room air purifiers selling dehumidifier machines costing upwards of ₹50,000. Most people still rely on naphthalene balls and camphor-based cupboard fresheners that are cheaper and easier to find. Yet somewhere along the way, I seem to have caved to the placebo of fusion over sublimation.

I now want to see the liquid trickle into the bottom compartment for me to believe it's working.
