Baldwin filters opinions

[dgc76]

I ran Motorcraft & NAPA gold for years because of the base plate end bypass. Neither have them now. My car, my wife’s car, my son’s Bronco, my daughter’s Bronco and my two mowers use the same filter. I have run a bunch of FL-910S the last few years. The glue problem with the FL-910S reported here concerned me. I cut the last few take offs open and the glue problem was present in all. I put a SuperTech on on my Focus the last oil change. Seems Mann Hummel is getting pretty inconsistent with their quality.

Thinking of switching to Baldwin, since most are USA made. Opinions?

This and Micro Guard Select from O'Reilly's I suppose.
The Baldwin P40134 isn't going to filter better than the MG/O'Reilly's MSL10241...and the MG will be $9.99

Baldwin's website lists a nearby, fairly serious parts shop. I'll see what one of my cartridges (w 2 O-ring kit) costs in person.

Many here frown on the whole company but they make good filters. The Boss line is a very well built filter as an example. Many more readily available options than Baldwin. Go down to you local auto parts stores and check out what the filters look like for your individual applications.

Yeah, the Motorcrafts have went down the tubes with the glue issue. They will never be used on my Coyote again.

I have some information about Baldwin filters. Yesterday, on 3/7/2025 I went to pick up an entire case (12 filters) of Baldwin B33 filters to fit my new 2025 Toyota Rav4 SUV. I have gone down a rabbit hole on filters lately looking for a filter to use other than the Toyota OEM filter. The way the Toyota (Denso) filter is built inside I don't agree with. Many others are built the same way with the high-pressure (plugged filter) bypass valve built into the leaf spring that puts pressure on the filter internally, holding it together. It is not just Toyota, there are many designed like that on the market. Anyhow, I was looking at the Mobil 1, Wix XP, Bosch, Purolator Boss, and many others. I watched most of them being dissected on YouTube by the Whip City Wrencher site. There are many filters that are more money with their fiberglass media and quality designs. Toyota allows a 10,000-mile oil and filter change interval with their filters. I like Baldwin filters. They are manufactured in Kearney, Nebraska and Yankton, South Dakota. They are owned by Parker Hannifin Corporation, with offices all over the world. They may manufacture filters in other countries too, I don't know. My Baldwin B33 filters were made in Kearney, Nebraska. I talked to a technical rep at Baldwin about the B33 Baldwin filters. I made fun of the filter media "keeping the bird nests and small stones" filtered out. The B33 is rated at 23 nominal and 45 absolute. The guy lets me know that the Baldwin B33 matches the Toyota 90915-YZZN1 OEM filter very closely on paper and with actual testing of the Toyota filters in their engineering dept. Anyhow, I decided to go with the Baldwin filters since they are made in USA and evidently if sifting out the bird nests and small stones Toyota oil filters do still allow for a 2 to 3 hundred-thousand-mile engine life that is good enough for me. I will change my oil and filter every 5000 miles or six months, whichever comes first, anyhow. Now, to what they cost. If you order Baldwin Filters online, they are much more expensive. There are a few parts stores here in town that carry Baldwin filters. Arnold Motor Supply (Auto Value) store is running a sale on Baldwin Filters right now. The list price is $18.63 which nobody would ever pay or need to, even on the internet. My net sale price was $5.07. The bill came to $60.84 plus $4.56 tax with a grand total of $65.40 for 12 B33 Baldwin oil filters. To get a decent price, go to the Baldwin Filter website and find out who sells them in your area. They are sold worldwide. You will get a better price on Baldwin Filters at a local parts store. Baldwin is big into Heavy Duty and industrial. You may have to go to a Peterbuilt shop or something. Well, that was more information about Baldwin filters than most people would ever want to know.

This gives current information showing that the Toyota OEM filters haven't increased in efficiency ever since Amsoil showed the independent ISO 4548-12 efficiency comparison graph back in 2011 of various OEM filters. The Toyota filter was shown as 51% efficient at 20u, which pretty much matches the 23u nominal efficiency (50% @ 23u) relayed by the Baldwin tech rep.

Is there somewhere to find this data, but updated?

The highest claims I'm seeing presently in my limited time to research this stuff is the Donaldson Blue filters which claim something like 99% at 15 microns.

Baldwin makes high quality USA manufactured filters. Mostly in Kearney Nebraska and at their "Hastings Filter" plant in Yankton South Dakota. I am sold on them myself. There is none of that constant leakage around the leaf-spring stye bypass valve as you see in the Toyota, certain Fram and other brand filters of that design. Baldwin is a good solid design. They are owned by Parker Hannafin Corporation, a worldwide company. Get on the Baldwin Filter website, https://www.baldwinfilters.com/us/en.html and look up your filter part number for your application. There is almost always a local parts house or class 8 truck dealership that offers Baldwin filters. You can find them on their website. I ordered a case at a reduced sales price. Once a year Baldwin puts on a sale for one month nationwide, I just don't remember which month it is. Do not order Baldwin filters online, as their online price seems to ALWAYS be jacked up. Anyhow, that is my .02 cents on Baldwin Filters.

The info given in post 5 seems to correspond to the old ISO 4548-12 efficiency info I was referencing in post 6, so sounds like it hasn't really changed. Toyota will never give out the efficiency data on their filters.

The B33 has applications besides Toyota. Ask the rep to send the Toyota test results. It’s only talking so far, then someone latches onto to it and creates a story based on hearsay. Then that story is posed as fact when it is speculation. Then others start to believe the story. That’s fine, it is only an oil filter chat board.
I would love to see a full Toyota N1 test result from a trusted professional source.

My thoughts on Baldwin: Good old brand that makes your typical run of the mill filters, its what every old guy out there swears by due to their build quality. The reality: Their standard cellulose media products are nothing special unless its the MPG line with synthetic media which some are unobtainable and have very little applications due to short number of size offerings. Baldwin makes filters for some OEMs. I think they're owned by Parker now.

 

[Bighorn2500]

I’ve used them in the past off & on. Been happy with them, just do your homework as some have better efficiency ratings them others ex. 27 micron absolute on the B7491 with silicone anti drain back which is the direct cross to the FL910S. Others are in the 40 micron range absolute.

You can cough up the cost of an official ISO 4548-12 test if you're that curious. The old ISO 4548-12 efficiency info shown by Amsoil is believable because they aren't going to show data like that if they can't back it up in case Toyota lawyers knocked on the door. If the efficiency was made better today, I'd think Toyota would elude to that in some way.

Me too. I am just going by what I was told by a technical employee in the customer service dept. at the factory where the Baldwin B33 is manufactured in Kearney Nebraska. I guess there is no reason to believe me, and for that matter, there is no reason for anybody to believe you. I am not a "trusted professional source". Nobody has to believe me, or as far as that goes the tech guys answering the phone at the Baldwin filter plant don't have to be believed either. I have to assume they have the technical papers on all the filters they manufacture. The key here in
the statement I just wrote is the word "assume". I do know Baldwin makes decent filters, but nobody has to believe what I write or say. I am quite aware of that.

I believe you. I like Baldwin oil filters and Zoro is another place to get them as an add on to other goods to get free shipping. Phone guy. I don’t know, it doesn’t make sense unless the B33 was made specific for Toyota only.

I stopped using Toyota OEM filters on my Tacoma after BITOG member river_rat did some bench testing ... the Toyota filter didn't do very well compared to others. Then the Amsoil ISO 4548-12 efficiency info showed up that pretty much corresponded with the bench test. That's when I went to Purolator PureOnes, then to OG Ultra after Purolators started tearing media.

Here's the summary he made: https://filtrationcomparisons.weebly.com

Here's a shot of how much debris the Toyota let through compared to some of the others he tested the same way.

In case you missed it, some guys on YouTube tested Baldwin and its efficiency was horrible. Literally only beat Toyota.

The things it did well in I suspect were because it's letting so much particulate through the media just doesn't fill up.

Brand Ranks: Wix, Napa Gold, Autozone, & Baldwin

 

[ZeeOSix]

^^^ Except the Boss really isn't the "clear winner" (it's ISO 4548-12 is 99% >46u per Purolator/M+H). That's all been hashed out in a number of threads since that BR testing was done.

Baldwin Filter's purpose in life is to match the efficiency of the OEM specs of the filter they are making. They don't try to filter out more, or less, they try to match the specs. They are well constructed and made in USA. So, if that particular OEM wants playground pebbles and bird nest to go through their filter, that is how Baldwin will build it, on purpose. They try to match the efficiency of the actual Motorcraft or Honda filter you would carry out of their dealership. You can buy filters from other filter makers that have 20 micron or smaller absolute ratings out there. Some of those don't match the OEM efficiency. In other words, the car makers own filters allow the bird nests to come through, that is what they want. Baldwin is not competing to make a filter that simply fits and takes out the tiniest micron of debris. Some industrial hydraulic filters OEM's require the 20 micron absolute or smaller ratings. Baldwin makes those filters to spec. for those companies also.
