Maintenance and care for your boat dehumidifier

It is right to say that the efficiency of any equipment depends on its maintenance. Using a dehumidifier properly will impact its performance and efficiency. Here are a few pointers that you must remember when it comes to caring for and maintaining your dehumidifier.

Cleaning and replacing filters

The air filters are a crucial part of the unit. The moist air and dry air that circulate back and forth through boat dehumidifiers will contain several contaminants. These have to be removed thoroughly to prevent the spread of respiratory illness and to maintain the efficiency of the filters.

Dust, pollen, pet dander, mold spores and mildew, and other microscopic allergens can be removed from the air files in the dehumidifiers by cleaning. Remove the filters and clean them with soapy water and a gentle brush. You can use a vacuum to dry the filter or simply air dry it.

If the efficiency of the filters is poor you must consult with an expert to consult if they need a replacement. It is advised to replace the filters if necessary to prevent the further spread of allergies.

Proper storage and usage

If you are not using your dehumidifiers on the yacht anymore you must store them correctly without any access to moist air. The damp and moist air in the bay area can seep through to damage the unit when it isn’t stored in an airtight space. Follow the instruction manual to know how your dehumidifier can be stored when not in use.

Troubleshooting common issues

While advanced dehumidifiers come with features that can hint at the common issues with their solutions, other simpler models might have troubleshooting solutions in the manual. If there are any issues that persist and cannot be resolved by following the guidelines given in the manual, you must reach out for professional assistance at the earliest.

How to keep moisture out of boat cabin? [6 Tips & Tricks]

Ventilation: Open out the windows and vents in your cabin or boat to increase the chances of natural ventilation.

Cooking: If your boat has a stove and the heat from the cooking circulation is in a closed area, it is going to fill up the place with excess content of moisture and humidity. Make sure you have an exhaust when you cook.

Bathing: If you have a warm shower inside your cabin, make it a practice to turn on the exhaust fan or a portable moisture absorber. This will work to immediately remove the stagnant water and moisture.

Moisture control products: Simple and readily available moisture absorbers like silica gel and carbon pellets are choices to remove moisture from tight spaces like bags, cabinets, and lockers. These areas can also hold moisture and contribute to humidity.

Moisture absorbing: Repainting the cabin’s interiors and the walls can also be adequate to keep moisture build-up at bay.

Dehumidifiers: Last but not the least, investing in a dehumidifier is the best option to successfully exhibit humidity and moisture control.
