I live in an area with a high water table, and my basement gets quite
humid; it recently flooded when the sump pump failed. The basement
area is about 1300 to 1500 sq ft, and is divided into rooms, though
only two of those rooms (one of which is a store room that also houses
the sump) have doors. There is also a small room housing the gas
furnace and hot-water heater. I used to have a small, inadequate
dehumidifier (built into the partition between the main room and sump
room) that ran all the time and did little good. One satisified owner
in a similar locale has recommended the Wave Home Solutions
ventilation unit, which should certainly use less power than a large
dehumidifier, but I'd like other opinions. Anyone here have experience
with it? Any suggestions on what to look for in a regular dehumidifier?
All the Wave does is vent the basement, just put a fan in a basement
window and there is your expensive "wave". It wont do much, ive tried
my own homemade setup and it didnt help me. My Energy Star humidifier
uses about 4-5$ a month on a 600 sq ft basement and keeps my humididty
low, if its below around 68 in the basement when you plan on using it
get a low temp model, consumer reports has reviews online.
I have a damp basement split into three rooms. I used to run two
dehumidifiers down there, then learned that setting up a fan on a
timer in one of the rooms allowed me to get just as good results with
only one dehumidifier. I have the fan run three times a day for two
hours each time. It uses a lot less electricity than a second
dehumidifier, and moves the air well enough that one dehumidifier can
work efficiently. It'd be a cheap thing for you to try out and see if
it works for you. Note: I use a box fan set on the floor, because the
dampest air is down by the floor, and I figure anything smaller than a
box fan wouldn't cut the mustard.

I looked into the Humidex, which is essentially the same thing under a
different brand. It was expensive, so I ginned up a homemade version
using six-inch ductwork running up the wall from the floor and venting
out a basement window. I placed a six-inch fan on the floor right into
the duct, so it would draw the damp floor air up and out the window. I
turned off my usual dehumidifier/fan combo and gave this setup a
three-day test, allowing it to run constantly. I quit after three
days, because the increase in humidity in the basement was _very_
A couple things to note - a basement dehumidifier gets a big boost
when central a/c is running - but I'm in a climate where I run central
air only occasionally, so my basement dehumidifier usually doesn't get
that assist and does fine anyway. I did not have the central air on
when my DIY device was running, and frankly, just exhausting the
basement air (which is all it does) wasn't sufficient to keep down the
humidity. This concept probably works a lot better when central a/c is
running, because the central a/c ends up doing the dehumidifying. So
if you run a/c most of the summer, it might work out better for you. I
expect the commercial version probably works a bit more efficiently
than my DIY version, but given the results of my DIY version, I ended
up disconnecting it and going back to my usual dehumidifier/fan combo.
Frankly, I was disappointed. I'd hoped I'd be able to get away from
running the dehumidifier altogether. Nope.
In June I had a Wave system installed in my ranch home for $1500. I am not
handy so I didn't dare try to build the system detailed in this forum.
In installer thought our basement door was too nice to cut in a vent so we
just leave it open. The late June and July weather was like august. High
heat and humidity. The central air ran continuously.
My concern was the cost of electricity for this system and using the air
conditioned air. Well, I just received my electric bill and it was about
the same as last August where the AC was always on.
AND, my basement is dry and there is no mildew smell. Up until now I used
a dehumidifier but it never dried out the basement and there was always a
damp like smell. Also it cost about $35-45 a month to run.
So, the bottom line is that the Wave works. I know it was costly, but it
works much better than a dehumidifier and uses much, much less

My Wave System continues to do the job but I wanted to add something.
When it was first installed I noticed that it constantly cycled with the
fan turing on and off every few seconds.
I c contacted a service rep who was very helpful and assured me the unit
was operating properly and was getting itself adjusted.
A week or so ago he called me back and explained that because they had
received many calls similar to mine, they looked into the matter and
developed some better software to control the unit. He told me they were
sending me a new control panel unit, at no cost. I believe the man's name
is Ron and he was very friendly and helpful. He was wonderful to deal
The next day I received the unit. All I had to do was remove four screws,
unplug the circuit board and install the new one. A five minute task. I
then returned the old one in a Fedex mailer they provided.
The unit no longer goes through the constant cycling. It gets the
atmosphere to me desired setting (55%) and maintains it. When it drops
below my setting, it runs at a very low speed.
Now that is what I call great customer service. I just wanted to share
this info because it is nice dealing with a company like this.

I have had the Wave now for 4 years. It has not done what it was intended to do.
Dry out the basement. I was told that the unit needs to be installed in the
furthest corner of the basement (2500 sqft) and the draw will large enough to
pull the humidity for the entire area. I also asked if it mattered that the
basement was finished and they said no sweat. My basement has been as wet as
ever along with mildew. It was essentially junk. I am now looking for a true
dehumidifier system, even if I have to pay more money per month to run the
system. What am I saving? More dollars for a problem never solved? I believe I
was mislead by sales on the capacity the unit could handle, along with the
knowledge of a finished basement. Stay away from this product! Do more research
for a dehumidifier vs. Wave. Trust me.

IMO, the big problem with Wave is that they only tell you part of the
equation. They tell you that it works by drawing fresh air into the
basement, while exhausting the air that's there. And that it costs
a lot less to run than a dehumidifier. That last part apparently is
based on how much it costs to run the Wave fan. What they ignore is
the rest of the story. As it blows air out of the basement, the make
up air is brought in from upstairs, from the conditioned house air.
So, in summer, you're pulling AC cooled air into the basement, then
pumping it outside. The makeup air for upstairs comes from outside.
So, you're paying to cool that air with your AC unit, it just doesn't
show up in the electricity number for the Wave unit.
In principle, it seems like is should work. Essentially, AFAIK, it's
just an exhaust fan on a humidistat. I could make up similar from
off the shelf parts for not much money. IDK what they charge for a
Wave, they won't tell you on the website, which IMO, is never a good
thing. The real question is how efficient is it versus a dehumidifier
and how much it costs versus one.

That seems to be the concept, just an exhaust fan with a humidity sensor
controlling when it turns on. If the humidity is above a threshold, it switches
the fan on, otherwise, it's not needed and turns off.
If you don't have an AC in the house, it'd actually end up pulling outside air
into the house, and if it's humid outside, makes things worse in regard to
humidity. The radon and pollutants would be helped, but if humidity is the main
purpose, the dehumidification has to be done either by the separate AC system,
or if it's dryer outside to get a benefit.

Maybe we're missing something, but I haven't seen anyone explain

One benefit for sure is you're getting fresh air into the basement,
so I don't doubt it will make it smell better, reduce typical
basement odor, etc.
i find that simply opening the basement windows ONLY on those days that the sky is blue and the outside humidity is low and running a circulating fan 24/7 works pretty well.
I do run a standard dehumidifier if there is a long spell of humid days.

it does not work and then no resonse after the installation . No answered
emails or return follow up . a scam and I fell for it and did not trust my
intuition . They say to set it on 30 percent. after three days nothing but a
basement still at 70percent humidity which I bought a meter at the hardware
store . No response back from DALE.

Is it only drawing air from upstairs in the house? What's the temp and
humidity there? It won't be lower humidity than that and if it's say
78F temp upstairs and 60F in the basement, then the humidity in the
basement will be higher than that upstairs as the air cools. The system
relies on pulling conditioned air from upstairs into the basement while
pushing basement air outside. It also depends on how it's installed.
I would think that if you had the exhaust on one end of the basement,
the air coming from upstairs at the opposite end, it would work well.
If you have the exhaust at one end and the air from upstairs coming
down close by, it will just be sucking air from upstairs and pushing it
outside, not doing much to change the humidity in the rest of the basement.
