Design and Size
The Aprilaire 1850 is not pretty. The older review called it a large gray metal box with visible bolts. It is about 14.5 by 12.5 by 27.5 inches and weighs 75 pounds. Air goes in on one side and out the other, and the control screen sits on top. It is made in the U.S.A., and the listing says it has corrosion-resistant aluminum coils.
Looking ahead, big American-made dehumidifiers like the Aprilaire 1850 keep their value because the market around them keeps changing. Smaller brands vanish, ratings shift to the new test and prices climb. A 95-pint Aprilaire is a ten-year purchase for many homes, and makers now add Wi-Fi and duct kits to the same box.
Features That Matter
- Controls. Built-in digital controls with a display, which can face the front or the top.
- Filter. A washable MERV 8 filter that catches dust and mold spores.
- Outlet. You can discharge air from the side or the top, so it fits tight spots.
- Drain. No tray to empty. Run a hose to a drain, or place the unit over one.
- Defrost. An automatic defrost control for cold rooms.
- Leveling feet. Four feet keep it level for proper draining.
- Warranty. 5 years, per the older review.
The older review put the output at 95 pints a day under AHAM test conditions (80 degrees and 60 percent humidity). That matches the listing’s 12 gallons.
The risk to watch is the coverage number. The older review put the 1850 at 1,900 to 3,000 square feet, while the Amazon listing says up to 5,200. Both cannot guide a purchase. A wet basement and a whole home are not the same job, and an oversized unit costs more to run. Expect more listings that stretch coverage to match a bigger number. Size by moisture load and local humidity, not by the largest figure.
Noise and Upkeep
The older review measured 47 to 54 dB, which is fair for a unit this size, but it still belongs in a basement or a crawl space. Clean the filter and flush the drain port and hose once a year. Compare it with the smaller Aprilaire 1820 Pro and the AlorAir 198PPD if you are weighing options.
Coverage: What to Trust
The older page said 1,900 to 3,000 square feet. The Amazon listing says up to 5,200. Use the lower range if your basement is damp or the house has heavy moisture sources. Use the higher one only for a dry house with a light load. Our how to choose the right size dehumidifier guide shows how to size by room conditions.

FAQ
How many pints does the Aprilaire 1850 remove?
The listing says up to 95 pints a day. The older review tied that to AHAM conditions of 80 degrees and 60 percent humidity.
How much space does it cover?
The older review said 1,900 to 3,000 square feet. The listing says up to 5,200. Plan on the lower figure for a damp home.
Does it have a bucket?
No. It drains through a hose or over a drain.
Is it loud?
The older review measured 47 to 54 dB. It is a basement or crawl space machine.
Final Word
The Aprilaire 1850 is a strong, long-lived machine for a large, damp space. For a normal damp basement, a smaller unit is enough and costs far less.
What happens next: expect more ducted units with smart controls and service plans, sold at four-figure prices. If your home has a real moisture problem, this class of machine is a sound investment.
