Aprilaire 1852 Dehumidifier

The AprilAire 1852 Dehumidifier is Made in the USAFollowing in the footsteps of our most popular crawlspace dehumidifier is no easy task, but the lighter, more compact and newly redesigned AprilAire 1852 (formerly the 1850F) 95-pint basement dehumidifier keeps all of the features that made the 1710A so great and improves on them! Instead of the rotary dial humidistat, the 1852 features a digital display with push button controls and an integrated humidistat. Every six months, the control panel will even remind you to clean or replace the MERV 8 air filter. This new AprilAire crawlspace dehumidifier removes five more pints of moisture per day, for a total of 95 pints, and still uses less power than comparable models. Best of all, with its lighter weight and slimmer profile, the Aprilaire 1852 95-pint basement dehumidifier is now thin enough to fit snugly between most floor joists. The new 1852 model now includes an inlet duct collar and outlet duct collar for horizontal or vertical discharge and can be ducted in mechanical closets to HVAC system, to whole home, or in basements to pull air from and return dehumidified air to the HVAC return duct or to discharge to the supply duct. Casters allow for easy mobility in basements, and the included five feet of drain line can be used to drain the unit directly into a floor drain or into a condensate pump for situations where gravity isn't on your side.


  • Removes 95 pints/11.88 gallons per day (@ 60%RH, 80° F), that's FIVE MORE pints per day than the popular 1710A dehumidifier
  • Provides three times the moisture removing capacity compared to standard portable dehumidifiers
  • Lighter and more compact than the 1710A, the new slim profile allows it to fit between floor joists and studs
  • Easy to use simply run the drain line, plug it in, set the humidity level and let the unit do all the work
  • Can be ducted in basements, to HVAC system in mechanical closet, or to whole home without an air handler
  • Designed for horizontal or vertical discharge
  • Easy to read digital control display w/ integrated humidistat
  • Automatically senses moisture levels by sampling the air every hour and runs only when needed to maintain humidity set point
  • Powerful 245 CFM fan combined with the water removal rate means the new Aprilaire 1852 dehumidifier can cover 2200 - 5000 sq. ft.
  • Half inch, cabinet insulation for increased efficiency and quiet operation, just 60 dBa on high
  • No messy tanks or buckets to empty and clean. Optional water drainage:Includes drain adapters and five feet of drain tube or can routed to a condensate pump for a more versatile drain option

Works really well and would recommend.
It really does the job in our 1500 sq ft unfinished basement. I just hope it lasts for the 25 year design life. All the other DH's are made in China and don't last. Had one go bad, manufacture replaced under warranty then that one failed, both Freon leaks. It would be to noisy if the basement was finished. I had one minor issue with the drain hose leaking where the hose adapter goes into the side. A small dimple caused the problem. I wrapped it in Teflon tape. then reinserted all is well. Living in SE Pa with a kilowatt meter attached it will run $13-$15 a month at 55%. Achoo had the lowest price and it was delivered in 2 days from the factory. Locals told me this was lower than there cost. They wanted $1600.

Aprilaire 1850 F Crawlspace Dehumidifier Reviews
Aprilaire 1852 (formerly the 1850F) Dehumidifier

As the first part of redesigning the entire Aprilaire line of home dehumidifiers, the new AprilAire 1850F dehumidifier borrows much of what worked so well with its predecessor, the 1710A, but improves upon a few key points. As the last several years have shown, the 1710A was an ideal unit for drying out your basement or crawlspace, and 1850F retains the critical features while offering a better control panel and display, higher water removal capacity, and a slimmer profile. Let's dig a little deeper and see what makes the new Aprilaire 1850F dehumidifier an excellent fit for any home or basement.

What I like about the Aprilaire 1852

AprilAire dehumidifiers have long been know for being powerful units, and the 1850F is no exception. With a strong motor and superior airflow, this newly redesigned crawlspace dehumidifier surpasses the 1710A by 5 pints per day, removing a total of 95 pints in a 24 hour period. That's nearly 12 gallons of water removed! Though it is a powerful unit, it is not as loud as other crawlspace and basement dehumidifiers. This is because of an upgraded fan assembly and silence insulation, and it's so quiet that you'll likely never hear it operate from the living spaces in your home.

An integrated humidistat has always been a feature of Aprilaire dehumidifiers, but in lieu of the rotary dial, the 1850F has a digital display. No longer do you need to refer to the user manual to determine what "dryer" equates to, nor do you have to use a separate humidity gauge to get an accurate reading. The LCD display will also flash a reminder every six months to wash or replace the MERV 8 air filter. This filter keeps the motor free of debris while improving the air quality in the space where the 1850F is operating. Washing it once after six months of use then reset the display, and six month later when it appear again, simply replace the filter to keep your drying at its best.

The only significant complaint with the 1710A dehumidifier (aside from the lack of a digital humidistat) was the size. Both the old and new models do have casters but the weight and dimensions of the 1710A made it difficult for some to use in their crawlspace. No more. The Aprilaire 1850F dehumidifier is trimmed down. Not only did it shed nearly 20lbs. in weight, but it now has a more rectangular profile instead of a square one. It is actually thin enough to fit between most floor joists or studs, and this will make installation a lot easier for most folks.

This model is does NOT significantly add to your monthly power bill. It doesn't quite reach Energy Star qualifications but uses less power than many comparable models. How does it do this? When you initially start the machine, set it to 55%. It will likely run a during the first day or two as, like with many things in life, it's harder to get something than to maintain it. So while it pulls moisture from the air, the air will then in turn pull excess moisture from the surroundings. After this initial run, you should then set the humidity to your desired level. Once every hour the 1850F should kick on and run, sampling the air to check the current relative humidity. When it senses the humidity is higher then your set point, the condenser will operate and begin extracting moisture. If the humidity level is still below your desired level, it will shut back down and remain quiet for another hour until it samples the air again. This type of operation is efficient in that it uses significant power only when it needs to and will sit idle when not needed.

On a personal note, I was glad they dropped the P-trap with the new model. For most people, it wasn't a necessary component and caused more confusion than anything. You still do get a couple adapters if there is a specific way you want to drain the condensate, and there is 5' of included drain hose that you can use in conjunction with a condensate pump or simply run to a nearby floor drain.

Like all AprilAire dehumidifiers and unlike most you'll find on the market today, the 1850F is proudly made in the USA.

Lastly, the 5 year warranty is among the best of all dehumidifier manufacturers.

What I did not like about the Aprilaire 1852

For crawlspace, and even some basement applications, a condensate pump is handy to have. With the AprilAire 1850F dehumidifier, it can easily be used with a condensate pump, but one does not come standard.

In the past, I was hard pressed to find many drawbacks with the popular 1710A dehumidifier, other than size and the manual humidistat. The new AprilAire 1850F dehumidifier eliminates both of those concerns and improves in a couple other areas to make a good machine better. For damp basements or musty crawlspaces, the 1850F is looking to pick up right where the 1710A left off, as one of the most reliable, efficient and durable home dehumidifiers available today.

Product Questions

I have a crawl space of about 2500-2800 square feet. Will your larger unit work in my crawl space? I am going to have my heating and air company put this in for me. Thanks.
I have a very wet 600 sq ft basement and was considering an Aprilaire 1850f. The furnace and electrical panel are starting to rust and altho I have a couple portable dehumidifiers going when it is wet down there they arent doing the job. It seems like the 1850f might help alot. Is it easy to unload and hook up just plug into a normal outlet or does there have to be a special/exclusive outlet? I tried to do Live Chat but couldn&#39t get it to stay up for me. Need an answer asap please. Thanks K
Does the drain have to be hard piped on gravity fall or does the unit pump out the condesation?
