Honeywell is one of the biggest brands in dehumidifiers so it was natural to choose the Honeywell TP30WKN dehumidifier as one of the best dehumidifier for crawl spaces.

It is energy star qualified which will save energy and money on lower power bills.

It has a washable air filter which prevents white dust from being dispersed, something that many other dehumidifiers have problems with. And there’s no need to replace the filter- simply hand wash it and then put it back inside the dehumidifier.

You will know when to clean the filter because there’s a filter clean alert on the dehumidifier.

The water tank is detachable making it easy for you to empty it when it is full. It holds up to 30 pints per day before needing to be emptied.

If you prefer the automatic method, there is a drain hose included with the dehumidifier so that it empties the water for you using gravity. This is the method we recommend since the dehumidifier will be used in a crawl space.

The Honeywell 30 pint dehumidifier has a 24 hour on/off timer which will save you energy and money and there’s an auto restart function in case of a power surge. This saves you worrying about switching it back on if there is a power surge- it will automatically happen!

What Causes Mold Growth In Crawl Spaces?

If you have an older home, you may have noticed something furry-looking growing on the wood in your crawl space. This is most likely mold, and the reason it’s growing in your crawl space is because of three things.

Moisture: There is moisture in your crawl space, and if this moisture level reaches over 60%, you have the perfect breeding ground for mold.

Temperature: Mold has an ideal temperature for growing. But don’t start thinking that a colder temperature will stop mold growth: if mold can grow on food in your fridge, mold can grow in your crawl space in the middle of winter.

Food: Every living thing needs food, and mold is no different. Mold feeds off wood, and certain types of wood provide more nutrients for mold to grow.

Mold is a big problem for those suffering from asthma or other respiratory problems. Mold spores that are in the air can be inhaled by a person. This can trigger an asthma attack or other symptoms of an allergic reaction.

The best way to combat an allergic reaction to mold or to prevent an asthma attack caused by mold spores, is to eliminate the mold.

How To Eliminate Mold In A Crawl Space

Firstly, it’s important to check whether there is water present in your crawl space due to leakages or other plumbing issues. These issues need to be fixed immediately.

It’s also important to make sure you have proper drainage around your home, to stop any rainwater from entering your crawl space.

If your crawl space is damp, then the best way to eliminate the dampness is by using a dehumidifier.

In Conclusion

Your crawl space doesn’t have to be a breeding ground for problems- dehumidifiers help remove the moisture from the air to create an optimal humidity level. By choosing the best dehumidifier for crawl spaces, you will notice reduced incidence of mold and the associated respiratory problems. And a stronger and safer foundation for your home!
