PUREONE BETA RATES!

[SHAMUS]

If your math/their beta claims are correct, how/why the differencies with what they say are their filtering efficiencies, i.e.:

10um - 92.8% / beta - 98.7
15um - 99.2% / beta - 99.9

If we go by their beta ratios, the PureONE is even better than Purolator claims (micron efficiency).

 

[Gary Allan]

like I said, magic filters.

 

[Jim Allen]

I've nothing against PureONE fitlers. Those numbers are just so much better than they have any right to be that you just have to be skeptical of them until proven true.

 

[SHAMUS]

For anyone who like to call and speak directly to the man who provided the beta data:

Brian Crawford
Purolator Senior Production Engineer
910-426-4279 (North Carolina)

Just think about something - IF these beta numbers are correct, do you think I will leave any on the shelf for the rest of you guys? Good Luck!

I really don't see where or how you're getting the info you posted in your quote above (red text).

Among the questions I have is where they got the idea and maybe particle size for those numbers. There is no procedure that would give you 6.69 microns or 11.42 microns.

99.5% efficiency is normally written as something like B4(c)=200, meaning there are 200 times more particles 4 microns and larger upstream than downstream. So they are saying: B11.42(c)=100

I think Purolator is using interpolation of their data, and therefore you get strange particle sizes for against the uniform beta ratios.

That's what it looks like if written in the format you're using.

In summary:

50% = B2 = below 5 µm
90% = B10 = 6.69 µm
95% = B20 = >8 µm
98.7% = B75 = >11 µm
99% = B100 = 11.42 µm
99.5% = B200 = >13 µm
99.9% = B1000 = >15 µm

Danged if I know. I said at the beginning I have no clue how to figure this stuff out. I rely on guys like you and Gary to explain it to me! Basically, I used a S-W-A-G! I am still waiting for those of you who emailed Purolator for clarification to explain it to me.

 

[SuperBusa]

My "in summary" info a couple of posts above is what it boils down to according to the info from Purolator.

Based on the Beta Ratio data, they are saying the PureONE is actually 99.9% (Beta Ratio 1000) at 15 microns and above, even though they advertise it as 99.9% at 20+ microns.

 

[SHAMUS]

Then, if I understand you, they are 90% efficent at

Yes, I'm happy!

Yep ... That's what the data from the Purolator Tech indicates.

Note - it should actually be 90% for anything >7um (greater than 7 microns).

 

[SHAMUS]

In summary:

50% = B2 = below 5 µm
90% = B10 = 6.69 µm
95% = B20 = >8 µm
98.7% = B75 = >11 µm
99% = B100 = 11.42 µm
99.5% = B200 = >13 µm
99.9% = B1000 = >15 µm


Just for giggles, Royal Purple gives the following beta ratios for their filter:

B25 = 100 - 99%
B20 = 75 - 98%
B10 = 5 - 80%

Can't get anything out of Mobil 1 or Amsoil (tight lipped!)

 

[Gary Allan]

Amsoil Beta15=75 ..that's the spec they list. That is considered the "absolute" level of filtration nomenclature.

 

[SHAMUS]

GARY, SUPERBUSA, ANYONE ELSE WHO CALLED/EMAILED PUROLATOR:

Anybody heard back yet on clarification of the beta figures?

 

[Gary Allan]

Nope

 

[SuperBusa]

Nope ... no word back from my inquiry.

SHAMUS - the data Purolator gave you (passed on via Katrina from the Tech Dept) is pretty clear. If it's accurate, then the PureONE is a very efficiency filter.

They probably know this thread exists, and figure the data has been given to the masses.

Ain't the RP the same filter as an M1?

 

[SHAMUS]

Then, until someone can provide evidence that what Purolator provided on their PureONE (both filtering efficency and beta ratio) is wrong/false - IT STANDS, for me. Naysayers: don't just say they've got to be wrong - show us the evidence! (Sorry, Gary, I know you believe in the product you sell, but making snide remarks about the Purolator engineer is not disproving him).

No. Same manufacturer, but very different media in the RP.

The RP filter is much more like the AMSOIL EaO, Donaldson Synteq and Fleetguard Stratapore filters, because it has a synthetic glass fibre media.
