- Hi, I'm Parris and last year I did
a product review of a cleaner for getting
mold and mildew out of bathtubs, showers
and off the tiles.
After that video, I was contacted by this company, Eva-Dry.
They said, "Have you got humidity problems?"
"We can fix those."
They offered to send me out their new
air dry 365 dehumidifying system
that uses these cartridges.
It goes on the base that gets
the humidity out of them.
So you can put them back into use.
I said, "Sure, send me one out,
"I'd love to try it."
Plus I really like the name Eva-Dry.
It reminds me when you're at the peak
of diaper changing frustration
with a baby and you ask them,
"Are you eva dry?"

You can buy these components separately.
I think the cartridges go for about $20
and the base is about $30.
This set, if you buy it from their web site is $59
with everything you see here.
And I'll link to that down below the video.
I did see, at Target, they have this,
if you are in need of it right away
and want to run to the store and get it.
At Target, it looks like they sell you
the base plus one cartridge for about $50.
The advantage to having two cartridges
is that when you have one of them
on the base unit, with the humidity
being taken out of it,
the other one can be in place
absorbing humidity out of a closet
or out of a room.
Something else I liked about reviewing
a dehumidifier is that is was an excuse
to go out and buy a humidity gauge.
Used to have one of these that was
built into a weather station that gave you
outside temperature and humidity,
inside temperature and humidity.
All that cool stuff but it stopped working.
This is just an inside the house unit
but it does tell you the lowest point
the humidity has reached in the last 24 hours
and the highest point.
So I think with this, I'll be able to test
this out pretty well.
Eva-Dry makes a number of dehumidifying products.
So I'd seen their name before.
And everything seems to be based on
the silica dehumidifying gel capsules.
So I think that's what these cartridges are full of.
And there are little windows on them
that change color when they are
saturated with moisture so you know
it's time to put them on the base
somewhere else and put a new cartridge in
to keep up the humidifier.
Here's what comes with this package.
This is the blower unit with the switch on the back.
And you do have to plug it in to blow air
up through the cartridge.
Now it does have a warning in the instructions
not to cover the top and that the sides
may become warm or hot.
So I'm thinking this must have a heating element
in it as well.
Because if I remember correctly,
endothermic, exothermic, if you take liquid water
and you turn it back into gaseous water,
that should absorb heat.
That's why it cools down after it rains
and everything evaporates, right?
Yeah, so with that being the case,
I'm thinking that this has to be providing
some of it's own heat, that would speed up
the drying out of these cartridges.
I've never used something like this before
but, apparently, one of the great,
new features of this design is,
this can be ready to go again.
To use from completely saturated with water
to completely dry and ready to absorb
in two hours and, apparently,
it used to take a lot longer to have
these ready to use again.
Which brings me to the cartridges.
This is the top where you can see the window.
The crystals inside are closer to yellow than green.
They're not really bright yellow
but I believe that means they
can still collect a lot more humidity.
Probably weighs about a pound.
That's where the dryer unit will blow
the air up through this to remove
the humidity from it.
And then there are all the ventilation holes.
Now it rained here last night.
It rained and rained and rained.
So there's lots of humidity.
I'll get this fired up and see
what the humidity is in the house right now.
The air conditioner hasn't been running.
I've turned that off.
So that won't be a variable.
We've got central heating and cooling
so that would change the humidity in the rooms.
I'm, actually, going to test this out
in a closet rather than the bathroom
because the bathroom, I have the window open
when showering and then the air conditioning unit
and the door is open, people coming and going.
So, to test it and see the exact amount
of humidity it can remove from a small room,
a medium size closet.
That seemed like the best way to test it out
under controlled circumstances.
This Acurite temperature and humidity gauge was about $10.
I got it over at Fries.
You can also find it at Home Depot.
I'll put a link to it down below this video.
Does exactly what I want and doesn't have
any other fancy features.
I, basically, want to know what the high point
and low point of the humidity is
in a given room over a 24 hour period.
This takes one double A battery.
I put that in.
As soon as it came on, it showed 53% humidity
and where are we at?
75, 77 degrees.
Now the humidity has gone up
in the two minutes since.
Which, of course, it hasn't really
but as some air has circulated though this,
it's showing the humidity to be
a little on the high side in the house.
I was expecting it would be a little higher
but 60% is good.
If we can get it down to 45% in that closet,
I think this device will be working pretty well.
In normal humidity ranges,
from about 20% to 80%, this is accurate
to within about 3%.
Just in the few seconds since I changed
the zoom on the camera, it went down to 59.
Now it's up to 62.
So we're gonna average that out.
The cylinders come with hangers,
so you can attach this here
and hang it on the clothes rod
or some kind of hook in the room.
Or you can, I guess, set it flat somewhere.
I'll try one each.
I was going to use just one in the closet,
cause after all, it is a closet.
I'll show you the size of it.
But then I was reading how much water,
actually, is removed by one of these cylinders
going from completely dry to filling up
with as much water as it can hold.
It's 120 to 150 cc's.
Is that a lot?
Is that not a lot?
It's about four 1/2 to five ounces of water.
So that's all the water that's going
to be removed from the air in the closet.
Will that really make a difference in the humidity?
A measurable difference in humidity?
I'm not sure so I decided I'll just
go ahead and open the second one up,
hang them both in there,
give it a couple of hours and then,
have the initial check of the humidity,
see the follow up check if the humidity
has dropped and by how much.
I pulled the battery out of the humidity gauge
so it could start over with the high/low.
And it's been in the closet for a couple of minutes now.
Looks like low to mid 50's is the humidity percentage here.
Let me hang up the two cylinders
and then I'll close the door
and leave it closed for two hours
and see what it is when I come back.
As soon as I brought the two Eva-Dry
cylinders in here, the humidity started dropping.
But I think that's probably a coincidence.
I've put one like this up on the shelf
next to Tracy Island, the play set.
And the other one is over here,
past all the magic shirts and it's hanging
right on the clothing rod.
Well it's, actually, five hours later.
I'm gonna open the door quickly,
turn on the light and see what
the humidity gauge shows.
Here we go.
53%?
It got down as low as 49.
Back up as high as 55.
Hmmm, now the temperature has dropped
from 77 to 70 and there's something about relative humidity.
The warmer the air is, the more moisture it can hold.
So is it possible that at 77,
the humidity here might be 40%?
But at 70, it's 53%.
Let's take a look at the canister here.
It still seems to be about the same
shade of yellowish/orange.
This one also.
Well it's after 9 o'clock at night
which is not the best time for my brain
to try to understand sight Crometric charts
which are related to humidity
and air volume and temperature and enthalpy.
I downloaded them on here and I downloaded
this big program that allows me to interact
with the chart and adjust the different variables.
I think, as I understand it,
putting in my different numbers here
from what I experienced in the closet.
I believe that when I started out,
my dew point in there was about 15 degrees Celsius
or around 60 Fahrenheit.
If the temperature dropped below that,
I could get some condensation.
Whereas, when I was done,
when I had the 49% humidity at 70 degrees,
I think this is dew point,
was 10 degrees Celsius which is about
50 degrees Fahrenheit.
So, in order to get the water to condense
on objects in the closet,
originally, it would have had to just
drop to 60 degrees.
Whereas, after those canisters had been in there
absorbing some moisture, it would have had
to, actually, drop down to 50 degrees
in order to get some condensation on objects.
That's how I understand this.
So I think that means it, actually,
removed some of the humidity.
Again, I showed you the cup which
how much is the maximum amount
of liquid that can be removed
with one canister before it's completely saturated.
Is that a lot compared to the volume of air?
This is the kind of stuff you learn about
at nine in the morning, not at 9 o'clock at night.
So I don't really feel like I'm doing this justice.
I do believe it is taking some moisture
out of the air in the closet.
Maybe it needs more time to do that.
They do say you can, usually,
leave these a couple of weeks.
Maybe, it doesn't do that much
when you're humidity is around 50%.
Maybe it's when your humidity is 70%,
then you'll really see a big reduction.
I'm not sure on those things so I feel like
I may not be doing justice to the product.
But it's about all I can do right now.
I, actually, have jury duty to go to tomorrow.
So, I'm going to show you one more thing about this product
which I really think is working.
Then I got to go to sleep.
I've taken one of the canisters
out of the closet.
Still looks pretty yellowish/orange to me
but I want to show you how this works.
I'm gonna turn this on.
I did notice that the air coming up
through the little piece here, is definitely warm.
(air blows)
So there is a heating element in it.
I'm gonna put this on here.
And I feel a little bit of air
coming out all around it.
So it's doing it's job.
It's gonna heat the crystals up
and that will force the humidity out of them
and after a couple of hours of this,
they'll be ready to go absorb
another 150 cc's of water.
Now you, obviously, don't want to do this
in the same area of where you're
trying to dehumidify, cause this just takes
all the moisture you removed
and puts it right back into the air.
So, I imagine I would, probably,
do this in the garage or somewhere that
I really don't care about
the temperature and humidity there.
Now if I get empaneled on a case tomorrow
and it has anything to do with humidity,
I'm going to tell them, send me over to UT
for a couple of weeks, let me sit in on a class
to really understand this and then I'll be
glad to come back and be on your jury.
