Aprilaire Dehumidifier 1830 - 70 Pints Per Day with Automatic Digital Control (Ducted)

The Aprilaire 1830 dehumidifier will keep your family comfortable during humid days. This dehumidifier is designed to dehumidify conditioned spaces up to 3,800 square feet.

The redesigned 1830 dehumidifier by Aprilaire is engineered to install directly onto the duct work of your heating and cooling system, allowing you to efficiently dehumidify the living space. With the ability to dehumidify up to 3,800 square feet this is a perfect unit for your home or business, and with its compact size it will fit almost anywhere. This model replaces the Aprilaire 1730A.


By pulling air throughout the house via the return ductwork the 1830 dehumidifier will dehumidify the air and return the dry comfortable air back into the home by disposing of the excess water via a drain hose.  It works with or without the air conditioner operating so it works when you need it, not just when your air conditioner running. The unit comes standard with a built in controller to sense humidity and activate the dehumidifier.


Proudly manufacturing products in the USA, Aprilaire is known in the industry for manufacturing reliable, high quality products that are thoroughly tested before entered into the market.  Aprilaire proves this once again by coating their units with a protective layer to increase the reliability and life of the unit.  From a design standpoint, Aprilaire took extra measures to ensure quiet operation so you will not hear it operating throughout your home. 


The manufacturer recommends replacing or cleaning the 5443 filter every season or 12 months.

      I purchased a dehumidifier a few weeks ago and so far I am happy with the product and the price was good but I was more impressed with the free overnight shipping. I have yet to see another company match that!!

      I purchased this item about a month ago and so far it is doing excellent. The high humidity is soon to come but I think this product is gonna do the trick.

      My intentions are to install the AprilAire 1830 in my crawlspace once I finish the encapsulation process. Despite it not making it into the crawlspace yet, I did run it (ductless) inside the living area of my home. It appears to be sturdy and nicely made in all of it's aspects. It too; performs very well. Unlike portable Dehums - when it reaches it's set point - it shuts completely off, fan and all. Portable Dehums, the compressor may shut off when it reaches the set point but the fan continues to run, that equates to energy use and my peeve "noise". The ApilAire comes on every hour in an "air sampling" mode. It measures the R/H if there is the need - it turns the compressor on - if there is no need - it's shuts down. I am most certain it will work out in my crawl space encapsulation application - quietly.
