What causes mold?

Indoor mold is caused due to increased moisture content. It can be in the air or inadequate drying of clothes or flooring. This moisture content, coupled with high humidity, is the breeding grounds for mold. It is natural that the common building materials used can sustain the growth of mold and mold spores, they tend to absorb water. This is where dehumidifiers come to the rescue of extracting moisture from the environment, keeping it dry and free from the growth of mold and mildew.

What are the cheap ways to prevent mold?

Keeping mold away from every room in your house, no matter how big the size is simple with the help of the right dehumidifier. However, dehumidifiers do require a good investment, especially if you are looking at a big area to be covered.

There are cheap ways that can help to prevent mold from growing in your home, which you can follow. Remember, if your household is deep into the mold problem, dehumidifiers are the only way out. These are just some tips to prevent the problem from getting worse or from starting off.

Ventilate: Natural ventilation is a great source of keeping mold away. Letting sunlight and natural airflow into the home whenever possible is an ideal step. However, not all climatic conditions permit this. If there are natural ventilators in your home (windows and doors) or vents from the HVAC system or dehumidifiers, ensure they are cleaned periodically.

Keep humidity under check: Monitor the humidity level in your home at all times and intervene if you think it is going to cause a mold outbreak.

Mold resistant products: Another good step would be to install mold-resistant products. Mold-resistant drywall or mold-resistant Sheetrock, and mold inhibitors for paints, etc. These products do not leave place for moisture to linger or get trapped. Installing mold-resistant products will save you from unforeseen mold damage to property and your pocket!

Improve care for indoor plants: A common aspect many homeowners miss when it comes to mold damage is their indoor plants. Most of us love having them for aesthetic reasons and to purify indoor air.
What we often tend to forget is that the moist soil is breeding ground for mold, and it could become a reason mold creeps into other parts of your home.

Adding Taheebo tea to the water you use for the indoor plants can prevent the issue altogether. The oil from the Taheebo tree is popular for withstanding the growth of mold even in the rain forest soil.

How does a dehumidifier help with mold?

Just because your house does not have mold at the moment, it does not mean it will never happen. Mold is dormant in the air and on surfaces at all times. Even when these surfaces do not have EXCESS moisture to support mold growth, it is still dormant. A dehumidifier’s role is not to kill the mold, instead, keep the space dry and free from humidity. This will prevent the growth of mold and mildew.
