How to Select the Best 90 Pint Dehumidifiers

A dehumidifier, irrespective of where it will be used, will require that you consider some factors before making a choice. Some of the core factors include the following;

  • Moisture Level

The moisture level in the home determines whether you should get a dehumidifier or not. Once you are sure there is excess moisture, you want to be sure how much you have in excess. This knowledge will help you determine the capacity of the dehumidifier to choose for your home.

For very accurate measurements, you will need a hygrometer to get the measure of the level of excess humidity in the atmosphere.

You can also assess how bad the situation is using the visible effects caused by excess moisture in the home. These include musty smell, dampness, condensation on walls, and ceilings, among others.

  • Size of your room/space

The room size plays an essential part in the choice of dehumidifier you will choose. Dehumidifiers are majorly classed along the amount of moisture they can pull off the atmosphere in twenty-four hours and the size of the space they can cover.

Although, it is usually better to choose dehumidifiers with capacities and sizes that are higher than your current needs. This ensures that the device will be effective at getting rid of excess moisture in the home and keeps the air fresh.

  • User-Friendly Features

It is ideal to consider the moisture level present in the home and the space size when choosing a dehumidifier. However, all these will become unimportant if you end up with a dehumidifier that is not user-friendly.

Some features to watch out for in a dehumidifier that makes its use convenient include;

  • Filter Alert: This can also be referred to as a filter indicator, and it informs you when the filter in your dehumidifier needs to be cleaned.
  • Anti-frost setting: This feature prevents your device from freezing up in cold environments.
  • Auto-Start: Should a power loss occur, this setting makes sure the dehumidifier keeps running using the previous setting.
  • Automatic Humidistat: This feature sets your device to work in achieving the set humidity level. Once it does that, the device shuts off to conserve energy and resumes once the humidity increases.

These are a few features that will make using the dehumidifier convenient for you.

  • Water Disposal System

The dehumidifier will accumulate water extracted from the atmosphere into a water bucket. The bucket will need to be emptied regularly or once it is full to keep the device working optimally.

While this is common, some dehumidifiers also come with the option of direct draining. This allows the device to work continuously without the need to empty the water tank. It requires you to have a floor-level drain in place to use this feature.

In the absence of a floor drain and to avoid the inconvenience of having to empty the water bucket of your device regularly, you have to choose a dehumidifier with an internal pump.

The internal pump allows the dehumidifier to move water into a sink that’s not at floor level.

  • Energy Efficiency

Your dehumidifier will be running most of the time to keep the home’s moisture level at moderate amounts. To save the amount of money spent on utility bills, opt for energy star rated dehumidifiers.

You can enjoy ridding your home of excess moisture and saving on the amount of energy used at the same time.
