What are the benefits of a dehumidifier?
Dehumidifiers do more than manage indoor moisture. They actively reduce dampness, which prevents mould growth, musty odours, and potential health issues. By minimising allergens like dust mites and mould spores, a dehumidifier can help create a healthier living space. They also protect furnishings, clothing, and electronics from excess humidity, ensuring they last longer.
While they can’t eliminate existing mould, a dehumidifier prevents future growth by keeping the environment less hospitable for moisture-related issues. You should also ensure your home is properly ventilated for maximum effectiveness, particularly in damp-prone areas like bathrooms.
Additionally, modern dehumidifiers include features like laundry-drying modes and dual air purification, making them versatile tools for fresher, dryer homes.
Can you sleep with a dehumidifier on?
Yes, dehumidifiers are safe to use overnight and can improve sleep quality. Modern dehumidifiers operate quietly so that they won’t disturb your rest.
Do dehumidifiers use a lot of electricity?
Dehumidifiers are generally energy-efficient, and their benefits often outweigh their running costs. Modern models optimise energy use, and their power consumption varies depending on their size, capacity and use. According to andoo.co.nz, running a medium-sized dehumidifier for eight hours daily costs around $0.88.
Which is better: Desiccant or compressor dehumidifiers?
When shopping for a dehumidifier, you’ll encounter two main types. Here’s a quick breakdown to help you decide:
Desiccant dehumidifiers
These models use a rotor with desiccant material to absorb moisture from the air. They excel in cooler climates as they work efficiently at low temperatures, warming the room slightly in the process. While desiccant units tend to consume more energy, they’re ideal for cold, damp areas.
Compressor dehumidifiers
Sometimes called refrigerator dehumidifiers, these models cool the air to remove moisture and release it back at room temperature. They’re highly energy-efficient and work best in warmer climates. While compressor dehumidifiers perform well across various temperatures, they may require defrost or antifreeze cycles to handle icy coils in colder settings.
Each type offers unique benefits, so consider your home’s climate and specific needs when choosing between them.
