Default Clearvue Cyclone is BEST

Wood Magazine march2014 page 74
After they tested it they stated it returned 20 times more dust than the Oneida tested a year ago.
Clear Vue returned more dust to particles then five single stage collectors tested last year.

ClearVue came out with the mini-cyclone CV06 for ShopVaC based on Bill Penz’s research FIRST.
But Oneida filed a patent for their dust-deputy first and then wanted Clearvue to “cease and desist”.

Lawyers should not decide that a lousier Oneida Dust Deputy had been copied by a superior design.

Buy Clearvue (the Chief) or the Oneida (the Deputy)
Both are Made in USA

The 2 inch Clearview is about $150. FYI

The more I do, the less I accomplish.

Great reviews and comparisons, Mike. There is nothing better than first-hand information from an actual user. Thank for taking the time to test and report.

The Comparisons are too superficial. Sorry.
1. Standard vacuum bags or filters cartridges will only catch dust >5 microns in size only.
So fine dust that are harmful to health if they pass though a bad cyclone or separator would also have pass though the filter bags or cartridge too.
To really compare, all separators must be connected to the same VAC with SAME brand & model of HEPA filter.
High Efficiency Particulate Air (HEPA) Filter. By definition a HEPA filter shall exhibit a
minimum efficiency of 99.97% when tested with an aerosol of 0.3 micrometer diameter. But NOT all claimed to be HEPA are the same.
2. Dust Deputy is not the best. They claim ONLY 99% - same level as what a $4 (Made in China) Cyclone claims.
"The award-winning design of the Dust Deputy cyclone uses centrifugal force to cyclonically separate and remove over 99% of dust and debris from the air-stream before it ever reaches your vacuum's filter, eliminating clogged filters and suction loss! "
A ClearVue Cyclone claims >99.9%

read Bill Pentz SCIENTICIC cyclone and dust collection research
Dust Collection Research - Home
and be educated more SCIENTIFICALLY.

That's not actually their relevant claim on their current website. This was just taken from the ClearVue website:

Separation of airborne dust is six times better than competing models. Independent medical school testing recorded separation rates at 99.9% of dust particles larger than 5-microns and 80% of fine dust particles sized to 0.5-microns. So little dust gets into the shop vacuum resulting in less filter cleaning or need for replacement filters. Continuous full airflow is uncompromised. The Mini CV06 is a great addition to any workshop. Used in conjunction with a shop vacuum, it is ideal for hand tool workstations and general dust clean up.

This is the claim from Oneida about their Dust Deputy:

The Dust Deputy will separate out over 99.7% of nearly any type of dust and debris, with less than 1% making it into the vacuum – significantly extending the life of your vacuum and saving you countless time and money on expensive replacement filters and dust bags!

These claims do not allow head-to-head comparison (funny how competitive companies always manage to do that). ClearVue claims 99.9% of larger than 5-micron dust particles, but only 80% of fine dust down to .5 microns. Oneida, on the other hand, claims 99.7% of all dust. Which is better? No clue.

I agree that both of these marketing claims are just that: marketing claims. They may be based on scientific findings about their units, but a marketing claim should always be read with a healthy skepticism.

I realize it is the micron-level dust that is injurious to health, but my reason for owning a Dust Deputy is to catch the big chunks and heavier sawdust created by my planer, CNC, and table saw, without clogging up my shop vac filter. Although I may have to empty the Dust Deputy bucket frequently, little or no noticeable dust makes it to the shop vac, so it can keep it running for a more extended period.

Regardless of the <5-micron filtering issues, I think a Dust Deputy or similar device is a helpful addition to any shop. My ceiling-mounted air cleaner filters out airborne dust to the 1-micron level.

Dust Deputy's design is very simple and made in China is $4 because it is original (=GENERATION 1) design.
In China they already have Generation 3 and Generation 5 design ($25) already.

DD's claim that does not specify 99% of what size of the dust so it is a misleading claim.

Bill Penz who did research said:
"My professor and engineer friends tested most brands and sizes of small shop vacuums, dust collectors, cyclone separators and air cleaners and I shared the results of those tests here on this page but within a week all had to be taken down. Two of the biggest small shop cyclone vendors and one dust collector vendor tied me up with litigation demanding that I remove these test results and also remove every instance of those vendor names from all of my web pages. I spent thousands on attorneys who all assured me we would win eventually, but at too high of a cost. All said that the courts almost never award damages or attorney fees in these kinds of business suits, so this all had to be out of my pocket. Worse, if I did not remove these test results and vendor names immediately, these vendors would be granted a court order to force me to pull down not just the results shared on this page, but all of my web pages for the years they could drag out these nuisance suits. Regardless, each of these suits would cost me at least $25,000 to defend and I do not have a spare $75,000 or more to throw away. Three different woodworking magazine editors shared they had the same problem where the big name vendors forced them to omit negative test results and to change their testing to make certain equipment appear to perform far better than it does in real use. I apologize in advance for not being able to share all our detailed test results."

ClearVue did not design their products. They just implemented Bill Pentz's design which was designed because no other vendors's design was effective.
