Question: How noisy is it , say 1 to 10. It is for a 1 bedroom condo, and I am concerned about the noise. Can an electric extension/cord be used ?
Document: This is my first dehumidifier. I'm really satisfied with it. Works pretty well the humidity indicator is very accurate.I really recommend this unit. In a few minuts 10 or less my room goes from 67% to 50% of humidity.
good unit, has three options to get rid of the water which is great depending on your situation of placement for the dehumidifier. I gave it 4 stars because the unit is a bit noisy if you have it where you congregate, but other than that the unit has been working quite well.
Works great! Love the auto-restart after power outages which we get a lot of. Not too noisy. Have hooked up to drain out through my AC and works great.
Had to replace a recalled dehumidifier of this volume. Ordered this one and the Whynter RPD-702WP Energy Star Portable Dehumidifier with Pump, 70-Pint because I needed 2, both were highly rated, and couldn't decide which to get. Ended up returning Whtnter because it was significantly louder and ran continuously to achieve the Energy Star rating, which also means that loud noise in 24/7.
Works well, pulls alot of moisture out very quickly. Pretty loud, but it is a big unit... not like it's for a bedroom or small space.
I'd give it four stars, but the first machine they sent me didn't work, so I had the hassle of returning it for a second one. The replacement machine removes humidity quickly, relatively quietly compared to other machines (still moderate noise of course), but removing the tray is not easy. If it was an empty tray, this would be less and issue, but the tray is usually full almost to the top so you'll need to be extra careful when removing.
My old unit did not get this hot although it was only rated at 45 pints/day. I would not place anything that would be damaged by this heat within 10 feet of the side. And I would not put it near anything that could combust if hit with so much hot air exhaust. From several feet away it feels like a hair dyer on max setting blowing on you!This unit has power outage restart which is nice for unattended use.
Bought this so that we could set it up to have continuous drainage. Still trying to figure out how the heck this can be used for continuous drainage! At our basement the receiver is full in 12 hours! Someone has to remember to empty the water twice a day every day!
Very versatile since it can drain directly into a floor drain, into the attached holding tank, or pump into a sink. I'm using the direct drain method which is the most convenient. I have a 1000 square foot basement and it is maintaining the humidity easily. I was concerned I might need 2 for that amount of area.
The drain hose is very narrow, but stiff and is easily concealed, unlike the large gravity drain hose my old unit used to have. The pump will only come on once there is sufficient water volume in the bucket. Hopefully this unit will remain reliable and not have to be replaced like most Chinese products that overflow our landfills.Hopefully this unit will not be recalled and the tremendous hot air it generates will not become a fire hazard.
Answer: Extremely quiet, mine is in crawl space below kitchen and I never hear it. I have mine powered by extension cord (heavy duty).
