How To Prevent Mold

How To Prevent Mold

The best mold prevention method is to keep your home clean and dry. One way to do this is to get an air purifier or dehumidifier

Air purifiers and dehumidifiers can prevent mold and reduce the musty smell that comes with mold. An air purifier cleans the air better than air conditioning system. HVAC ducts, where mold is found, can be a health hazard.   

Dehumidifiers, on the other hand, keep your indoor air dry in humid climates and reduce mold exposure. If you already have a mold problem, a humidifier will not help.

The devices are great in dry climates because dry climates are immune to mold. Another option would be to install exhaust fans next to any water damage in your home. 

DIY Mold Removal Methods 

How To Get Rid Of Mold

The process to get rid of mold involves donning protective gear, washing the area down, and keeping it dry. The good news is, there are many household products you can use to help reduce mold growth or wipe it out entirely.

When washing, we recommend that you use one of the following substances: 


Of all DIY household products, bleach is the strongest and most effective solution to remove mold. Bleach is strong, so it can’t be used on every surface. When using a bleach solution, your first step should be to dilute it before applying it to a surface, especially on wood products and furniture.

When using bleach, wear gloves and a face mask. If you can’t get rid of the mold with diluted bleach then call a professional because you have a serious problem.

Hydrogen Peroxide

Hydrogen peroxide is a non toxic remedy that doesn’t require protective clothing when you use it. The substance has the same tendencies as mold but is safer.

You can use hydrogen peroxide on your skin to fight serious infections, so if it gets on your skin you won’t have any problems.

Over all, it’s an effective way to kill mold and you won’t have to worry about having severe reactions after you use it.


Vinegar doesn’t always work, but it’s non toxic and the safest way to get rid of mold in your home. It can damage some surfaces but if you take it slowly and test it first then you won’t have any problems with vinegar. 

Not only does vinegar attack mold but it also works as a disinfectant. If you have a moisture problem, then pathogenic molds and toxigenic molds will be a concern if you have wet areas that go unprotected.

Baking Soda And Borax

This may not be the most effective way to remove mold in your home, but if you mix baking soda and borax with water and scrub you’ll be surprised. The solution can work with small problems but won’t be effective when fighting other molds. 

The substance scrubs the mold while lifting it and then cleaning the underside. 

When To Hire A Professional

When To Hire A Professional

It is almost better to hire a professional to get rid of mold. While some problems are safe to take care of alone, mold can be a serious problem and with serious problems, professionals are necessary. 

While bleach can help remove mold, you won’t know if you’ve taken care of the problem or delayed it

Possible routes of exposure are inhalation, if the contaminant is present in the air, ingestion, through food, drinking, or hand-to-mouth behavior, and dermal absorption, if the contaminant can be absorbed through the skin.

What Is The Main Objective Of Exposure Assessment?

The major objective of exposure assessment is to estimate the risk caused by exposure of a chemical contaminant to an individual and ecosystem. In office buildings, an exposure assessment test will be performed after it has suffered water damage.
