Thoughts on Air Filters

Hi All, I hope everyone had a nice Christmas and a Happy New Year. I want to ask if anyone has had had experience with or has thoughts on 1) The Walmart SuperTech Air Filters and 2) The Fram Air Filters.

The local Toyota Dealership here where I live has gotten completely out of control in some of their pricing. I called a few days ago and they want $30 for a basic Air Filter. I was in Walmart today buying Windshield Wipers for my Camry and on a lark I decided to look for Air Filters. Walmart has their Supertech Air Filter ($12) for my car and also they carry the Fram Air Filter ($14) for my car.

How about it everyone? Yes? No? Undecided. Thanks all and have a nice weekend.

Doesn't really matter, find one that seems like it is good.

If you compare a new OEM air filter vs WrongMart, Fram, Purolator, etc, you’ ll see how thin the element is.
Use the filter to look at a light source (ie indirect sunlight), and the thinness really shines through (no pun intended).

There are many Toyota dealers who sell parts online or brokers who sell genuine Toyota parts via dealers.
You can search “Toyota OEM parts” and a lot of these dealers show up.
‘You can also search “Toyota (insert part number)” and a lot of links to discounted OEM sellers will show.

I think I have used exclusively Fram from Wal Mart ever since I bought my car when it had 113,000 miles on it. I run the air filter about 20,000 - 30,000 miles depending on the conditions. Car has 591,000 miles on it now and no major engine work and doesn't smoke but looses about 2 quarts in 5,000 miles. Maybe I would only be loosing one quart if I had paid more and got a better filter but no complaints here.

The importance of air filter is often overstated. As I see it, any filter, except K&N, is fine. I just picked whatever cheapest at the time and I often ended up with EP Auto. There's nothing wrong with it.

I just watched the video Stillrunning shared and it looks like the EPAuto filter has the best balance of cost and performance. Also interesting that the filter I use performed quite poorly in the particle removal test in the video. Even so, it has apparently done at least a good job of protecting my engine from airborne dirt damage.

Any filter is always a balance between flow and particle filtration. Want to trap more dirt and maintain flow, double the surface area - not practical in cars.

What the video fails to test is how the filters perform throughout their life. The Wix has good numbers but what if it then becomes totally clogged at 1/2 its life? What if the middle filters maintain their numbers throughout their whole rated life? These tests show how the filters perform out of the box only. If you replace your air filter every week these test numbers may hold true. If you keep your air filter in for 12,000MI, well the test doesn't address how they will perform.
What he should do is put the filters in his test box and let the 55MPH fan run 24/7 for a week then redo these tests. Better filtration means the filter medium will become saturated faster and that may be a design consideration that isn't addressed here.

The only way to extend filter flow life is to make it less capable of filtration. How dirty is the air it's filtering over what time period. Taking a vacuum reading when a new filter is installed and compare that to the vacuum with a totally dirty filter would give you a range to monitor.

Since I need an air filter too. So I looked around. It is a no brainer to me that buying Denso from Amazon is the best option for this one today.

You can even subscribe and save and there is no shipping.

The weather here has been fluctuation between cold to warm and I wanted to wait for a warmer day to replace the air filter in my Camry and I got a warmer day today so I did it. It was more difficult that I remembered but I got it done. I didn't take loose the hold down bolt for the cruise control cable and I cut the daylights out of my forearm trying to pull the old filter out and work the new filter in. My arm right now is coated in Bacitracin and wrapped in a couple of 4 x 4's. Again, the last time I changed the air filter was 2 years ago and I do not remember it being such a struggle even with not removing the cruise cable hold down bolt. Next time I will know better.

Interestingly the old air filter was not all that dirty. Just a light coating of dirt on the peaks of the filter media. I thought about putting the old filter back in but I bought a new filter, so I decided to put that one in. I paid for it, I was in the job bleeding and all, and I wanted to get my money's worth for the filter, so I put the new one in. I bought a Walmart air filter and saved $12 over the Purolators I have been using but I don't think I will be going back to the Walmart air filters. The rubber gasketing that surrounds the filter media is very cheap and squishy and I had a heck of a time getting it to seat into the channel in the air box but I finally got it. Interestingly when I opened the air box there was a shredded paper towel in there. I am guessing that I left it under the hood from a project and somehow it got sucked in so I just pulled the remnants out as best I could.

Even with the old air filter being in the car for 2 years I only drove approx, 12,000 miles so I think this filter I will leave in for 4 years or so. I was very surprised that it was as clean as it was but I guess I live in a clean-ish area. That's a win for me. :)

The Toyota air filter is expensive but its really much more substantial than say a fram.


I just buy a toyota one, and blow it out every so often with compressed air from the engine side out...... been doing that for years. Only replace it when it gets really brown / stained looking. Even then you probably don;t need to unless its torn.


Back in high school a teacher brought her cressida to the shop to get fixed. It would drive, but would bog horribly once you got above 20mph.

It had the original Toyota air filter form 1985. The air suction side literally looked like a crammed vacuum cleaner bag filled with dirt,/ dust leaves, roaches......you name it. the shop vac couldn;t suck it up and I had to grab and DIG it out.....The engine side looked brand new. In fact, you couldn;t tel lthe other side f the filter was crammed packed with garbage / dirt if you didn;t look......

I once had a 68' Mercedes 300sl 6.3 Liter, and I had it's factory service manual which was three inches thick or so. In that manual Mercedes said to clean the paper filters by tapping the dirt out of them and blowing air through them backwards, and that you could do this a number of times before having to buy a new paper filter for the car. I figure if this is okay with Mercedes, who back then was hand-building the highest quality cars and engines on Earth, it is okay for any vehicle, and that most likely the only reason it is not common knowledge and known today is that in a Capitalist society, they prefer it if you use up as many natural resources and throw as much money at them as is possible. Always remember, the USA will never do anything for it's citizens unless it makes a billionaire more wealthy.

Blowing air through an air filter to "clean" it is poor economy. The likelihood of making the pores larger is high (note the pores are microscopic, so your naked eye won't be able to the difference, but over time your engine can).

Air filters from reputable brands (Toyota OEM is good for me) are not expensive, and don't require replacing all that often. Makes it a non-issue.

I'll just post this again.
