Dehumidifier Tubs 500ml Pack of 20 Moisture Absorber – Blue
Product description
What it is
These are 500ml dehumidifier tubs designed to absorb excess moisture from the air. Packaged as a set of 20 in a blue finish, they are a simple, no‑fuss solution to damp, mould, and musty odours in confined spaces around the home.
How it works

The tubs use unique hydrophilic crystals that draw water from the air. They require no power, batteries or setup — just remove the foil seal, clip the lid back on, and place where damp tends to gather. They’re designed to be leak‑proof and quiet, so they won’t disturb daily activities.
Where they’re useful
They’re presented as versatile moisture absorbers for bathrooms, kitchens, wardrobes, garages, basements, caravans, boats and other damp‑prone areas. The compact design means they can sit neatly in cupboards or corners, protecting multiple spaces without clutter.



What to like about them
On the page they promise weeks of damp protection: each tub lasts around 1–3 weeks, depending on humidity. The high‑capacity crystals can absorb up to three times the tub’s own weight in water, offering a longer interval between replacements. The pack of 20 supports broader coverage across a home, office or vehicle, without frequent restocking.
Things to consider

If your environment experiences very high humidity or you need continuous, heavy moisture control, you may find you need to swap tubs more often than every 3 weeks. Some users may prefer a model with a visible moisture indicator or a fixed replacement schedule. Also, the fixed blue colour and generic design mean they blend in rather than make a feature of damp control.
Who it’s for
They’re well suited to short‑to‑mid term damp control in smaller spaces or in areas where mains powered dehumidifiers aren’t practical. They work well in bathrooms, wardrobes, caravans or cars where moisture tends to accumulate but a plug‑in unit isn’t convenient.



Who it isn’t for
If you need near‑continuous moisture management in a very damp environment, or if you want real‑time feedback on when to replace the units, these tubs may feel lacking compared with more active solutions.
When it makes sense to buy

Opt for this pack if you’re looking for affordable, low‑effort moisture control across several rooms or spaces over a period of weeks, without any power consumption or noise. They’re a straightforward solution for occasional damp issues and for keeping multiple small spaces drier with minimal effort.
Before you buy
Check the humidity levels where you plan to place them and estimate how many spaces need damp control. Consider where you’ll store the tubs when not in use and how often you’ll need to replace each tub over time. Remember they’re best used as part of a broader plan to manage damp rather than as a cure for severe damp problems.



Practical use example
Imagine placing a tub in a damp wardrobe and another in a bathroom alcove. Over the course of a couple of weeks you’ll notice less condensation on surfaces and a reduction in musty smells. When a tub reaches the end of its life, you’ll simply swap it for a fresh one from the pack.
Quick comparison context
If you’re weighing options, consider a non‑electrical moisture absorber that gives you spread across several rooms but requires regular replacement. For ongoing damp environments, a more powerful or noticeable solution might be preferable, for modest, occasional damp needs, this 20‑pack offers tangible value per space.

Final verdict
Final verdict: Worth considering if you want cost‑effective, low‑effort moisture control across multiple small spaces, without noise or batteries. It’s a practical fit for casual damp issues and for users who value simplicity and portability. If you’re after real‑time indicators or heavy‑duty damp management, you might want to explore other options, but for steady, low‑maintenance relief in several spots, this pack offers clear utility.
