I am trying to select a filter for my vehicles. I would appreciate an input from those who are more experienced than I. Below I have the flow and filtration data I have received through emails and through the archives.
Purolator sent me the following on their filters in an email:
The flow rate of the L20123 is 3 gallons per hour according to the catalog.
The flow rate of the L20033 is 4 gallons per hour according to the catalog.
The flow rate of the L30005 is 5 gallons per hour according to the catalog.
Purolator Premium Plus filters are rated at 10 to 40 microns with
efficiencies varying from above 90 per cent at 40 microns to above 50 per
cent at 10 microns.
Baldwin said the following about their filters:
The B39 and B9 use cellulose filter media. The filters are 22 micron and are flow tested at 3 GPM. The gasket and anti-drainback valve are made out of nitrile rubber.
I also found in the archives the beta numbers for a Baldwin filter.
22 micron nominal ( Beta @ 2 = 2) and 45 absolute (Beta @ 45 = 75)
From Patman's post a little while ago I found the beta numbers for Wix filters:
Beta: 2 =10, 20 = 25, 75 = 31. Average micron is 19
I also got the flow numbers: "Our filters will flow 7-9 GPM under normal operation"
Now the problem with the Wix is I can't get the largest filter, the 51049, with the ADBV. But I figure that the Purolator and the Baldwin aren't even close to the Wix numbers. The Baldwin seems to have really poor filtration numbers(only 50% at 22 microns) compared to the Wix. Since the Wix also has the highest flow numbers as well, I see no benefits to using the Purolator or the Baldwin.
Now, the only bad thing about the Wix are the fact that I can't get the large 51049 with the ADBV. But I figure that since the smaller filter already flows better than the biggest filter by Baldwin or Purolator, then there are no benefits to having the large filter other than extra capacity. And since I don't run my car on long intervals, wouldn't this make the Wix 51258 my best choice, even though smaller??
Pricewise (CDN $), I can get the Wix for $8 each in a case, or about $5 each for the other two (in largest form). If the Wix is significantly better, then I would pay the extra for the Wix.
Any input on my conclusion would be appreciated. I am I missing something in these numbers? I am a novice at this, so experts please comment!
