Article from Baldwin - "Understanding Beta Ratios"

[Bookmaker]

Based on the article from Baldwin Filters at the link below, which states that Beta Ratios can be expressed as Bx=nn (where x is the particle size in microns and nn is the efficiency), how should I then interpret Wix' published Beta spec of B2=20 for the 51372XP filters I just purchased?

Would that be 2 microns at 95%?

B2=20 means 50% efficient at 20 microns. Horrible beta ratio.

Not according to the article I linked.

"filter beta ratio can be shown as Bx=20 where "x" is the particle size in microns, or, it can be said that this filter is 95% efficient at removing "x" size particles"

Not worried about using my Wix XPs now. B2=20 means 95% efficient at 2 microns.

Post up a link to an official WIX beta spec on their XP filter.

Typically, WIX writes beta ratios in the following format example:

http://www.wixfilters.com/Lookup/PartDetails.aspx?Part=51042

Beta Ratio: 2/20=6/20

This means,
Beta 2=6, which equals 50% @ 6 microns and
Beta 20=20, which equals 95% @ 20 microns

Unless WIX has changed their beta ratio format, I'm assuming it's in the same format as they have always used in the past.

Many people have called WIX tech department about the beta ratio of the XP, and they keep saying it's 50% @ 20 microns. Nobody can believe it, but that's what WIX advertises. Personally, I don't think they really know what they are talking about.

Give WIX tech department a call yourself, and let us know what they say about the XP.

Wix is using the Bx=nn format for beta ratio on their XP filters. The following is cut/pasted from the Wix website. Beta ratio is near the bottom.

http://www.wixfilters.com/Lookup/InterchangeMultiSearch.aspx?q=xg2&o=me (This page provides links to the 51372 and 51372XP filters. Normal filter beta is listed using the old format. XP filter is listed using the Bx=nn format.)

Here's the only "technical" info that WIX shows on their XP. All fluff, a joke IMO.

Really, my previous post isn't "technical"? You linked to a marketing brochure.

By publishing a beta ratio of B2=20 for the XP, Wix is clearly stating that it is 95% at 2 microns. Follow the link from my previous post and see for yourself.

I was linking to WIX's own info on their XP filter. It is NOT very technical. Do you see any beta ratio of any kind of efficiency listed there? I don't.

If you think that beta ratio format really means 95% @ 2 microns, then that would be an absolute miracle. A full synthetic media filter in the passenger car application isn't capable of such an efficiency.

There is NO way it is that efficient. Like I said, it really means 50% @ 20 microns, which goes in step with the beta ratio format WIX has used all along.

Like I suggested ... call WIX Tech Dept and see what they say.

 

[Bookmaker]

I don't need to call them. I am convinced it is a very good filter. Wix published B2=20. Baldwin's technical paper explains that means that at 2 microns it is 95 percent efficient. Getting ready to put one on my Challenger. I'll do a UOA next October to see how the insolvable a come out.

Done going back and forth on this.

Have a nice day.

 

[ZeeOSix]

If the WIX XP was actually 95% @ 2 microns, the whole internet would be on fire with the news. It's not.

Call them ... you will see. Others here have had long drawn out discussions about it with the WIX Tech Department. It's been discussed in a number of threads over the last couple months.

 

[ZeeOSix]

Chew on dnewton's post linked below for a bit. I'm sure he might chime in and tell you all about his long drawn out discussions with WIX about the efficiency specs on the XP filter.

dnewton's take on XP beta ratio

 

[ZeeOSix]

Read this thread ... you see, WIX has their own format for beta ratios.

WIX Beta Ratio Format

Notice the quote in the first post, which is directly from WIX when asked how to read their beta ratio numbers.

 

[ZeeOSix]

Filter Council TSB on Beta Ratio

Note this statement in the TSB above - which is how WIX formats their beta numbers:

"This same ratio information can also be stated as B 2/20/75 = 5/10/20. Both equations state the same information in two different ways and are both accepted by the industry."

Just want to make sure others don't make the same mistake the OP did when reading WIX beta ratio numbers.

 

[KCJeep]

He clearly wants to believe he found a miracle filter with an efficiency rating light years ahead of all other available filters. You'd think Wix would want to promote that fact instead of telling people it'll catch small rocks.

Modest they are!

Leave him to his delusions he's happy with it.

 

[Bookmaker]

I spoke with a knowledgeable person from Wix this morning and he stated that for the XP filter, the B2=20 does indeed indicate 50% efficiency at 20 microns. So they do state the efficiency backwards. I stand corrected.

He said their most efficient filter is their premium filter, so I will be running that.

The XP is intended for the combination of extended drains and severe use. Wix marketing does not spell this out clearly. No doubt there are a lot of people using this who think that they are getting a better filter for average use when they are not.

Glad to have the official word on it.

 

[ZeeOSix]

Like I said ... it's a horrible efficiency based on word right from the WIX Tech Department themselves.

Some here think it's a mis-print since other full synthetic filters (like the Ultra) run at 99% @ 20 microns. If the XP is indeed 50% @ 20 microns, I wonder why they made it so inefficient.

I'm sure if WIX got enough phone calls about the XP and were surprised on how inefficient it was, WIX would look into the beta ratio they are specifying to ensure it wasn't a mis-print. One would think anyway.

I was impressed at how knowledgable and friendly the Wix tech rep was. He spent a lot of time explaining things.

Did he say anything about why the efficiency rating is so bad for a full synthetic oil filter?
