Lastly, desiccant and houseplants can help reduce indoor dampness but the outcome is minimal.

Disadvantages of Owning a Dehumidifier

Let's start with the bad news first. The number one concerning factor in a dehumidifier is obviously the cost, follow closely by the maintenance. These 2 reasons itself will be enough to deter buyers and current owners from continue operating the machine. No matter if the dehumidifier is used in the basement, room, garage, or living hall, the issue remains.

A Surge in Electricity Bills

Dehumidifier is one of the biggest electric hoggers home appliances. On average, a full-sized 70-pint dehumidifier will cost you $10 a month or $120 a year. The cost could cut to half if you pick a smaller capacity unit like a 30-pint model, but could also double if the run time hour is twice as long. This is because there are condensation and heating processes involve to extract water from the air. The entire dehumidification uses a lot of watts of energy and will push your electric bill skyrocket on continuous operation. The only way you could save up on the operational cost is to pick an energy-efficient unit with Energy Star Rated.

Neverending Maintenance

Like an air purifier, dehumidifier requires schedule maintenance and cleaning or else it will not work. Depending on the drainage options you opt for, a person may have to routinely empty the water in the bucket every 1-3 days depending on the room dampness. Even if you rely on the convenience continuous pump or gravity drainage, you will still need to check on it every now and then in case of overflow. Then there is the permanent filter that requires cleaning every month or so. Without doing so, airborne contaminants will be redispersed back to the air instead of being trapped in the filter. All in all, the above tasks are repetitive, time-consuming, and annoying especially when you need to empty a reservoir filled with water.

Warm and Noisy

A running dehumidifier will generate a gentle humming noise at low speed. At high speed though, it can be very loud that will disrupt a person’s daily activity. No matter how silent the manufacturer advertises its unit, there is bound to be some background noise. You could position the dehumidifier further away to lessen the impact e.g. bedroom or living hall. Otherwise, operate it at the lowest speed and kept it on longer so the same amount of moisture can still be drawn.

A dehumidifier can get warm on long operation hours. It will generate excess heat that may affect the room temperature slightly. If you are on a hot day or summertime, the extra heat is not welcome even though the differences are neglectable.
