Dehumidifier Size Categories

Medium-Capacity

Large Capacity

These types can remove as much as 60 to 70 pints per day. Furthermore, they are also suitable for working on a wide range of humidity levels, with no added functionality required. You may also be able to run the machines on a lower and quieter setting. If you have a large and wet grow room, go for the largest model you can afford. Even if it’s available at an extra cost, the performance makes it worth it.

Small Capacity

For midsized or large spaces that aren’t quite as damp, these models are typically claimed to remove up to 50 pints of moisture per day. While medium-capacity dehumidifiers can sometimes cost as much as large models, you’ll usually pay less.

Whole-House

These units are available as portable machines or can be used as the main add-ons to the existing central heating system. Most brands say these machines can handle large areas of as much as 5,000 square feet in size. These units tend to be less expensive but might have high energy consumption costs.

Best Dehumidifier Features

  • Auto-restart/ shut down – available on most dehumidifiers, this unit turns on the unit after a power outage. Furthermore, it also lets you set when the unit should no longer operate, and it’s useful for when you have blackouts. 
  • Hose connection – All the dehumidifiers in this category let you connect a hose for removing air from the dehumidifier. This function makes it easy to divert condensed air to the floor drain. This way, you don’t have to empty a bucket. If you have a grow room in the basement with a floor drain, then a dehumidifier with pump can direct water out through a slop sink or drain.
  • Timer – A timer is vital because it lets you program the unit to turn on and off when it’s not in use – which makes it a critical energy-saving function. To make the most of a timer, consider going for a dehumidifier that has LCD controls
  • Front control sensor – all the high-end dehumidifiers come with a sensor that turns of the unit if frost develops on the coils. This is a common occurrence in cold areas, and it helps reduce energy wastage.

  • Easy to empty bucket – this unit should also feature ergonomic handles, and cover that makes it easy to remove or carry when full

  • Silent operation – this unit also features advanced technology, without any compressor to make it quiet in operation. The ideal noise level should average at 60db per day, for convenient operation results.

Changes in the Dehumidifier Aisle

Most dehumidifier boxes come with indications of the pint rating, which refers to the amount of water the unit can remove in 24 hours. It’s an important factor to consider when you want to invest in the best dehumidifier for your needs. A good unit can remove an average 30 to 70 pints of moisture from the air, and deliver exceptional results.

Factors to Consider Before You Shop

Consider Where You Will Install the Machine

Noise is of significant concern in living areas. The measurements range from 3 feet away and can average at 50 decibels, which is the sound of a running fridge. Furthermore, you also have to consider factors such as the energy bills, and whether the machine will fit in the given space.

Large or Wet Spaces

On average, the level of dampness in your space is directly proportional to the size of the dehumidifier you can choose. The best large capacity brands can remove moisture fast and efficiently in a grow room.

Fix Existing Problems

Even the best dehumidifier will not work effectively if you grow room is not well sealed off, and moisture gets in. Consider downspouts work correctly, and the gutters close by don’t have any clogs.
