Purolator Boss PBL14476

[Fair enough]

Good. No chemical smell, no excess glue which is a cream color. Not much to show wrong. Older 2023, louvers not near as good as the filters just received made in 2025. Got new one for $4 so cut this one. Feels heavy.

Don't you just love that cream colored glue.
Very nice filter. I use these on my John Deere garden tractor. Thanks for cutting up this Boss PBL14476

My biggest fear was the media would look like an older Mann cartridge filter I looked at for light spots against a bright led lamp. Old showed many, the worst I had seen of the ten or so different types looked at. The old media looks just like this one by normal viewing, same backing, full synthetic. This new media showed none. Very tough to cut media with the backing. Pretty happy with this filter, not sending the new ones back.

EDIT: I misspoke, I went to look at my sheets & seen the same model number but I use the Purolator One PL14476 for my JD which is 99%@40.

Thread 'L14476, PL14476, & PBL14476 Purolator Classic, One, & Boss Oil Filter Specification Sheets'

Oct 15, 2023

Just want to add more info for these particular model filters from Purolator.

Boss 20K
One 15K
Classic ? The boxes I recently purchased show 5k but I've sent an email to tech support for clarification on this one since I know that some of these are now rated at 10K and I may of purchased old stock from Menards.

Also, This is a fairly small filter & it's interesting that the Classic L version gets premium filter media (Cellulose+Synthetic Fiber+Glass Fiber). You can see the rock catcher performance of this one & 3 grams holding capacity.

This again. When were those tests done, and why send media to Germany to be tested? Two questions.
It probably was the old stuff from Germany like I saw was full of light spots. The new stuff is guaranteed not the same. Pleasantly surprised at that since they were dirt cheap.

Purolator Tech line confirms the same efficiency that Mann-Hummel does (I called them not long ago). M+H controls what Purolator does, so if M+H says what efficiency their Purolator filter are then why would you think it's wrong. Call Purolator and confirm efficiency claims. They even now removed the efficiency claim for the Boss off their website after is was changed to 99% >46u like the M+H Spec Sheet showed.

If these are indeed some kind of Mercedes media the Germans would 100% know the efficiency. But you know what they say about those who assume….I believe the spec sheets and also have talked in-depth with tech line.

No “if” they are some kind of German media, it’s been around for decades. When MH bought Puro they started putting it in a filter called Boss. I think it has been upgraded as I explained. Anyway I will use them, have skin in the game, and not sure why PG dedicated users are so interested, but it’s a free country.

Maybe the Boss was more efficient than the current 99% @ 45u per Purolator Tech Line and the Spec Sheet before Mann-Hummel got hold of them. At one time, the Purolator website showed the Boss PBL30001 being 99% @ 25u ... but there is zero info from Purolator or Mann-Hummel that the Boss it that now. If it was more efficient than the current claim of 99% @ 45u then you can bet Purolator and Mann-Hummel would advertise it as such.

I’m interested in all oil filters and currently use two different manufacturers. This was your question.

“When were those tests done, and why send media to Germany to be tested?”

My answer was if it’s a German media they would absolutely know the efficiency. Spec sheets are updated with changes and are accurate per my in-depth conversation with tech line.

I don’t care what oil filters you use. But I enjoy passing on information about oil filters that help others. Baseless assumptions help no one. If Purolator officially announces a new media I’ll be the first to say you were right. I suspect something is going on as deep discounts and clearance sales are everywhere on these and on the One.

It’s originally German media, decades ago they started with it and Mercedes used it. I am not making baseless assumptions by asking when was this sheet done. That’s why I cut this one to see if the media was the same holey stuff they used in Germany. It’s not the same. You can’t go by what the phone people say over there, I talked to them too. It’s just talking. The baseless assumption is that these sheets are new. Yeah Im sure they send media to Germany to update the spec sheets WHEN THEY ALREADY STATED THE MEDIA IS 99+%@25 microns, and they have a test lab in the USA.
But you don’t use these anyway, so I don’t know why the deep interest but it’s a free country.

Let me repeat I’m interested in ALL filters as it’s one of my hobbies. THE OFFICIAL EFFICIENCY IS 99%@46 microns. Germany and USA agree on that….Purolator got caught with their pants down and corrected the website. Your conspiracy theory is beyond tiring.

This was a good thread….ruined by the OP.

Looks good

Still would like to see larger louver openings. Why not just go small hole openings and call it a day.

 

[Fair enough]

I looked at the louvers with a light, look fine. I thought they werea bit subpar looking in the hole. The newer filters I got are opened better. Since I posted I looked more at the media, there really were no light spots except I found one,

but just using a magnifying glass. To compare I looked at the Puro red I just cut open and found a number of light spots.
I also pulled apart the media, each half has many light spots but together they go away, for what it’s worth which isn’t a lot.

The louvers on the filter posted don't look bad ... seen a lot worse than these. It's pretty easy to judge the louvers by looking down the center tube at the right angle. Doing a "light test" on them IMO after cutting it open isn't as good as just looking down the center tube with a good strong LED flashlight and looking at the size of the openings. Besides, if someone is buying a filter with louvers they need to be able to look at them down the center tube and make a judgment call if they looked opened enough for them or not.

Doesn't mean it's the same media today, nor that the media efficiency has been the same for decades.

What filter "in Germany" are you comparing it to? And how are you making that comparison? What's the published ISO 4548-12 efficiency of the German holey media?

So you really think that Purolator in the US (who's owned and ran by Mann-Hummel) doesn't know what they are talking about wrt their own Purolator products?

If the Boss really was 99% @ 25u today, why did Purolator remove that from their website and then put 99% >46u for awhile, and not nothing is shown. Purolator Tech Dept told me on the phone a few weeks ago that the Boss and also the new Purolator gold "20K" are both 99% @ 45u. You can't find any info on the efficiency of the "20K" filter on Purolator's website or on the filter box.

Don't you think if the efficiency was really 99% @ 25u or 20u that they would be showing that all over the place. Just like with the WIX XP, it was shown to be 50% @ 20u on the WIX website, then the efficiency info disappeared. When I called WIX after that the told me the WIX XP efficiency was "proprietary". Hummm, wonder why.

But you don’t use these anyway, so I don’t know why the deep interest but it’s a free country.

Probably due to the interest in technical facts, not fiction or theories.

The desire by some posters for self-made delusion on this topic is bordering on humorous.

Left over old spec info. That's an Amazon ad that does not correlate with the current info directly from Purolator and Mann-Hummel.

That use to be on Purolator's website ... but they show zero efficiency info now for the Boss on their website. It was changed to 99% >46u for awhile before it disappeared.
