Bolaseca Dehumidifier Refill Tabs 3 x 450 g - Calcium Chloride Tablets 100 mm for Non-Electric Moisture Absorbers, for Motorhome, Caravan, Boat and Home

Bolaseca tabs are a refill for moisture absorbers that work without power or batteries. Each tab is 450 g of pressed calcium chloride, 100 mm in diameter and 39 mm high. The pack contains three tabs, each sealed in its own foil bag, so you open only the one you need. You place the tab in the basket of the absorber, where it draws excess moisture from the air and turns it into liquid that drips into the lower container. One tab looks after a room of approx. 20 m2 for 1-3 months, depending on humidity and temperature. It works well in a parked motorhome or caravan, on a boat, in a wardrobe, in a basement and in a holiday home.

How a calcium chloride tab works

Calcium chloride is a hygroscopic salt, which means it readily binds water from its surroundings. When the air is humid, the crystals absorb water vapour and slowly dissolve. This produces a brine that drips from the basket into the lower container of the absorber. As a result the humidity in the room drops to approx. 40-60%. Once the air is dry, the reaction slows down noticeably, so the tab is not used up for nothing. A pressed tab is compact, which is why it starts releasing liquid sooner than loose granules or granules in a fleece bag, which hold the water inside like a sponge for the first few days.

Which absorber the tabs fit

The tabs are designed for Bolaseca moisture absorbers and for many other absorbers whose basket or grid takes a tab of 100 mm in diameter and 39 mm in height. Measure the basket of your absorber before you buy. The tab has to lie flat and must not block the lid or the ventilation openings. There should be a sealed container for the liquid below the basket, because all the collected water ends up there. The tabs are not suitable for fleece bags or for containers without a section for the brine.

How long one tab lasts

How long a tab works depends on the amount of moisture in the air, the temperature and the size of the room. In a room of approx. 20 m2 one tab usually lasts 1 to 3 months. In the cold months it can last as long as 3 months, while in a hot and humid summer it may be used up in about 2 weeks. In the manufacturer's test at 25 degrees C and a constant humidity of 70%, a tab worked for 408 hours, which is 17 days. With three tabs in the pack you have enough for a whole winter storage season of a motorhome or for several changes in a wardrobe or basement.

Where they are useful

• motorhomes and caravans during winter storage and longer stays parked
• boats and yachts, especially in a closed cabin out of season
• wardrobes, closets and storage spaces where clothes pick up a musty smell
• basements, garages, attics and sheds
• holiday homes and second flats that stand empty for weeks

How to use the tabs

• take the tab out of its foil bag just before you put it into the absorber
• lay the tab flat in the basket and close the lid
• place the absorber on a level surface, out of reach of children and pets
• do not empty the liquid from the lower container too early, as it also binds moisture
• when the tab has dissolved completely, pour the liquid into the toilet or down the drain
• rinse the container with water and insert a new tab
• keep the remaining tabs in their sealed bags in a dry place

What is normal during use

Over time a tab may harden or swell. This happens mainly at low temperatures, when the salt dissolves less easily and crystallises on the surface. It is a normal stage of the process, and once it gets warmer or the humidity rises, the tab works at its usual pace again. If there is no liquid in the lower container for the first few hours, the tab is usually just getting started. Sometimes the refill turns brownish, orange or pink. These are traces of natural minerals or dust settling on the surface, and they do not affect performance.

Safety and protecting surfaces

• calcium chloride causes serious eye irritation (H319), avoid contact with the eyes
• if it gets into the eyes, rinse them carefully with water for several minutes
• follow the instructions for use to avoid risks to human health and the environment (EUH401)
• keep the tabs and the absorber out of reach of children and pets
• the brine can damage leather and metal, which starts to rust, so do not place the absorber directly on such surfaces
• in a motorhome, place the absorber so that it cannot tip over when the vehicle is moved, and take it out before driving
