What to Consider When Choosing a Dehumidifier for Crawl Space

High-performance machine
A basement and crawl space dehumidifier should be effective in removing the humidity and prevent allergens, mold, and musty smell in crawl spaces. With controlled humidity, you can protect your carpeting, furnishings, valuables, and other stored items from warpage, damage, and rot. Therefore, the dehumidifier should function efficiently to remove optimum level of humidity and keep the space dry and clean. A device with automatic defrost is always a preference.

Desired humidity level
A dehumidifier functioning in the crawl space area should be equipped with the provision to change the humidity level as per the environmental conditions. Also, the machine should be able to measure the humidity of the outside air to the current setting of the humidity level. If the humidity outside is higher than the current settings the device can start the dehumidification process automatically.

Compact and handy
A compact machine is a boon in modern-day living where spaces are an issue. Crawl spaces, basements, and storage areas are usually small and your dehumidifier should be compact and handy enough to be shifted, maneuvered easily, and stacked if needed. If you want to shift or transport your crawl space dehumidifier, it should be handy enough to be stacked and carried easily in transportation.

Robust
Since purchasing a dehumidifier involves a cost they should be durable and long-lasting. Dehumidifiers with corrosion-resistant aluminum coils, leak proofing and strong outer bodies will last a long time. ?Also, since they are kept in spaces where humidity levels are high, they should be sturdy to withstand the moisture and humid environmental conditions.

Proper water drainage
As a dehumidifier removes large quantities of moisture uninterruptedly; it should have adequate drainage facilities. Place your dehumidifier or the hose near the drain and all the water will flow into the outlet without causing any hassle of emptying the water tray. The dehumidifiers should have no leakage issues or will create a problem of dirty water puddles below the machine and need for frequent servicing.

Low maintenance and easy operation
A dehumidifier with low maintenance is well-suited for modern-day living where people do not want the hassle of everyday servicing of appliances. Select a dehumidifier with an interactive control panel that clearly shows all readings and is easy to use. The humidity level, the one/off button, and the other settings should be displayed clearly and prominently. Just a glance at the control panel and you are aware of all settings in the machine. The installation and setup should be easy and a lightweight dehumidifier is preferable as it can be shifted manually when needed. The air filter should be easy to clean.

Conclusion

So we have a clear winner. The Aprilaire 1820 Pro Crawlspace Dehumidifier emerges on top based on all the above parameters. It is a sturdy, durable, efficient and compact machine that effectively draws out moisture from your crawl spaces.
