Dehumidifier Buying Guide

A dehumidifier achieves this by employing a fan that rushes the air over refrigerated coils that cool down the air and sucks in the moisture from the air, disposes of it in a tank and disperses fresh air into the room. Certain Dehumidifier Features make it an ideal dehumidifier. A good dehumidifier should be able to remove a substantial amount of moisture from the air in the room. They need to run quietly as their presence in the room should be discreet and not disturbing.

Tips to Choose the Best Dehumidifier

The dehumidifiers also need to be very efficient, portable and easy to maintain. Following are the features that a dehumidifier should possess to be worth buying-

  1. Humidity control

Look for a dehumidifier that comes with automated controls to monitor and set the relative humidity level you want in your room. The optimum level of humidity in a house should be in a 40- 50% range in the summers and 30- 50% range in the winters. Dehumidifiers possess a default hygrometer that measures the RH in the room and displays it on a screen. A good dehumidifier should have an adjustable humidistat, which sets your desired level of humidity in the room, whichever you prefer and will maintain it all along. 

  1. Size of the dehumidifier

When purchasing a dehumidifier, it is essential to know about the right sized dehumidifier that will suit the size of the room you want to put it in. For a large room, a small-sized dehumidifier will remain mostly ineffective. The dehumidifier should fit properly wherever it is kept. To find yourself a right-sized dehumidifier, you will have to know about the size of your room in square feet. 

The drying capacity of a dehumidifier is measured in terms of the pints of water/ moisture that can be removed by it from the air in twenty-four hours. The majority of dehumidifier manufacturers offer a very easy to understand the sizing chart placed on the packaging of the dehumidifier. You can follow these charts to pick the right size dehumidifier for your desired room. 

  1. Water capacity

The water capacity of a dehumidifier means the capacity of the drip pans of the dehumidifier. Bucket size of the dehumidifier implies the amount of water it can collect at once. When the bucket size of the dehumidifier is small, you would need to empty it again and again. With a large bucket, you will have to pay more, it is obvious, but you would be spared from having to empty the bucket again and again. A few dehumidifiers also use the evaporation technology, which does not require any drain hose. 

  1. Washable filters

The dehumidifier should be easy to clean and maintain. Few models of dehumidifiers have certain filters that protect the coils from dust and dirt. The dehumidifier’s filters should be easily washable. Filters that can be removed and washed have a longer life- span as compared to those that cannot be washed and cleaned. 

  1. Noise Attenuation

Any electrical appliances tend to emit some sort of disturbing noise, so would the dehumidifier. The dehumidifier should not be a nuisance with its constant emission of noise as it would be placed in areas like bedrooms, living rooms, etc. where people tend to rest, work and relax. The dehumidifiers that have 2-speed fans work rather quietly at lower relative humidity. It is highly suggested to test out the noise emissions of a dehumidifier before buying it. 

  1. Automatic- shutdown

The automatic shutoff of a dehumidifier is shutting down of the dehumidifier when the water bucket of the dehumidifier is filled and has to be emptied. This is one of the essential features that a dehumidifier should have. Few dehumidifiers also have an indicator light that lights up when the bucket of the dehumidifier is full. 

  1. Energy efficient

A dehumidifier is an electrical appliance and an ideal dehumidifier should have the Energy Star certification on it, which saves money on electricity bills. The dehumidifiers that have government-sponsored label certification are guaranteed to consume less energy and even run efficiently.


It is better to buy a high capacity dehumidifier than purchasing a dehumidifier that has low capacity. The problem with small units is that they may run for very long durations of time. That too without really affecting the level of relative humidity and bringing it close to optimal levels. The right size dehumidifiers are the best option for moisture intense spaces like basements, dishwashers, clothes dryers, etc. also, if you live in an area where the humidity levels are soaring. You should opt for a dehumidifier that has a higher capacity than the square footage of the room suggests.
