Alva Baby Insert Absorbency Test

In the past, I’ve indicated that I do have a bit of a bias against “China Cheapies.”  Sure, they come in some cute prints, but they’re cheap for a reason.  Some people have sworn by the wonders of an Alva Baby insert… but I wasn’t convinced.  I decided that the best way to determine how good or not good Alva Baby inserts are is to do an absorbency test.

FuzziBunz Inserts Absorbency Test

I really do enjoy doing the occasional cloth diaper absorbency test post.  If nothing else, they’re always quite educational and can sometimes be surprising.  Recently, I put my FuzziBunz inserts to the test.  I’m a big fan of FuzziBunz cloth diapers.  In fact, that was the first diaper I ever bought.  I decided to put them to the test after noticing the size differences when comparing FuzziBunz One Size diapers to the new FuzziBunz Elite one size diapers.

All-in-Two Insert Absorbency Test

One of the questions that people have when they realize that “which diaper is the best” is outrageously subjective is “well, then which diaper holds the most?”  I’ve been going through and testing insert absorbency on some of my diapers.  This time, I’m going to do some all-in-two insert absorbency tests.  I’ll test the all-in-two insert absorbency of Flip Organic, Flip Stay Dry, and Swaddlebees Capri.

Prefold Cloth Diapers Absorbency Test – Bummis vs. GroVia

GroVia and Bummis prefold cloth diapers

GroVia and Bummis prefold cloth diapers

I like prefold cloth diapers.  They’re versatile.  They’re generally natural fibers.  They’re generally pretty cheap, even for premium cloth diapers.  Plus, prefold cloth diapers are really nowhere near as scary as they seem.  You can even fold them in a variety of ways without using pins or Snappis.

I’ve got two different types of prefold cloth diapers in my stash, and I wondered how they differed.  I have some Bummis prefolds, plus a GroVia bamboo prefold that I received for testing.

My testing method is sort of pseudo-scientific.  I did my best to manage it scientifically, but there are some flaws in my experimental process.  First, I weighed the diapers on my kitchen scale so that I could get a baseline.  After weighing, I soaked the diapers in one liter of water for two minutes.  I then gave each diaper one minute to drip out the excess and then weighed for absorbency. Weighing is effective, as one gram of weight is the same as one milliliter of water.  (No worries, my fellow Americans.  I’ll convert back to imperial measurements for you!)  Finally, I gently wrung each diaper to test for compression loss and weighed again.  My wringing out process is where the scientific aspect breaks down a bit: I tried to wring each diaper out evenly, but since I was doing it by hand, there’s no way to measure or calibrate the exact amount of effort in squeezing out the water.

Bummis:  Bummis prefold cloth diapers are 100% organic cotton.  I have the medium size, which are for babies up to twenty pounds.  At a dry weight, they were 89g.  During the two minute soak, they managed to absorb 336mL of water, which is 1.4 cups.  (Whoa.  That’s a ton!)  After compressing, the Bummis prefold still held 270mL, or 1.14 cups of water.  They hold nearly three times their weight in water!

GroVia: GroVia prefold cloth diapers are 55% bamboo and 45% organic cotton.  I have the size two, which is the infant size.  At a dry weight, they were 95g.  During the two minute soak, the GroVia absorbed 358mL of water, which is a little over a cup and a half of water.  After compressing, the diaper held 283mL of water, or 1.19 cups of water.  That’s just a little bit less than three times the weight.

The bottom line is both prefold cloth diapers are amazing at absorbing and surviving compression.  Give them a try and let me know what you think!

Cloth Diaper Insert Absorbency Test #1

A couple of days ago, my friend Heather over at The Parenting Patch did a great cloth diaper insert absorbency test on some of her inserts.  She tested out Fuzzi Bunz minky, Best Bottom Hemp, Sunbaby Bamboo, and Alva Baby bamboo.  When I shared it on my Facebook page, one of my readers asked about BumGenius diaper inserts.  With that in mind, I figured I’d pick up where Heather left off and test some of my own inserts.

Testing Jamtots, BumGenius, large Blueberry, and small Blueberry inserts

Testing Jamtots, BumGenius, large Blueberry, and small Blueberry inserts

I tested four inserts: a BumGenius 4.0 large microfiber insert, a Blueberry large microfiber insert, a Blueberry small microfiber insert, and a Jamtots hemp insert.

My testing method was a bit different than Heather’s method.  (This was just the easiest, most scientific way for me to be exact.)  I started out with my four inserts.  I weighed each insert dry.  After that, I soaked each insert in a liter of water for two minutes, then allowed the insert to dip for one minute.  I then weighed the wet insert.  To test how compression would impact each insert, I gently squeezed out the extra moisture from each insert and again weighed it.

Some metric conversion stuff for you: one liter of water is approximately a quart.  I used the scale to weigh the wet inserts because one milliliter of water weighs one gram, so it was just the most simplistic method I could think of.  Oh, and a cup of water is roughly 250 milliliters.

Jamtots:
dry weight: 58 g
soaked weight: 219 g
wrung out weight: 164 g

So the Jamtots absorbed 161 mL of water, which is roughly 2/3 of a cup.  After I squeezed out the extra water, there was 106 mL remaining, which is just under 1/2 a cup.  The Jamtots insert held roughly twice its weight in water after compressing!  For the compression test, the Jamtots lost 34% of the moisture.  I believe I squeezed the Jamtots most vigorously since it’s harder to tell by feel with the Jamtots insert.

BumGenius 4.0:
dry weight: 63 g
soaked weight: 311 g
wrung out weight: 221 g

The BumGenius 4.0 insert absorbed 248 mL of water in two minutes, which is just short of a full cup of water!  However, it’s microfiber, so it is more prone to compression than the hemp insert tested above.  After wringing out the extra water, it was down to 158 mL remaining, which is roughly 2/3 of a cup.  Had I been more vigourous with squeezing out the water, I probably would have lost more water.  What this demonstrated is that while microfiber is extremely efficient at absorbing moisture very quickly, it’s quite prone to compression.  After compression, there was a 37% reduction in absorbed moisture.

Small Blueberry:
dry weight: 41 g
soaked weight: 255 g
wrung out weight: 128 g

The small Blueberry insert absorbed 214 mL of water in two minutes, which is essentially 9/10 of a cup of water.  Again, it’s also microfiber, so the same details after wringing out apply.  After wringing out, I was left with 87 mL of water, which is just over 1/3 of a cup.  That amount of compression was more in line with a baby truly compressing the diaper.  After compression, there was a 60% reduction in the absorbed moisture.

Large Blueberry:
dry weight: 73 g
soaked weight: 377 g
rung out weight: 241 g

In two minutes, the large Blueberry insert absorbed 304 mL of water, which translates out to over 1 and 1/4 cups!  Again, it’s microfiber, which makes for a super fast absorption rate, but the same compression issues still apply.  After wringing out (again, more vigourously than the BumGenius wring out), 168 mL (or just under 3/4 of a cup) remained.  That’s a compression loss of 45%.

Ultimately, the winners for most absorbed after compression were:

1st: Large Blueberry
2nd: BumGenius 4.0
3rd: Jamtots
4th: Small Blueberry
