We have 100 Series Landcruiser, we are considering purchasing a Unifilter (an airfilter that you can wash and re use). Has anyone out there used one, are they happy with it or had any problems??????

Sandy and
Ross,
I had an RV 100 in '98 and got a TD 100 in '02. The turbo filter is a different part number than the standard, is quite a bit larger but still fits in the standard air filter housing. I have used the original Toyota air cleaner all the time for the following reasons:
If you read the sticker on the original air filter you will see it has instructions for washing it. I have two filters and just alternate between them. I clean them by giving them a spray of diluted CT-18 and water and giving them a blat with the hose from the inside first and then the outside. They usually take a couple of days to dry out.
I used a finer filter on my '92 GQ and went to the trouble of having it dyno'd with and without the finer filter and original filter and a properly oiled finer filter had an adverse effect on power output. That's why I'm staying with unoiled paper filters, regularly washed and changed out.
Please email to franjays@tpg.com.au if you wish to disuss any further.
Cheers
Jayson

I used a Uni filter for a few years on my Diahatsu Rocky until a diesel mechanic recommended I go back to paper airfilters to see if an oil weep around the turbo stopped before spending major dollars. It was a few years ago now but from memory I think his line of thought was it restricted airflow, I went back to paper filters and the weeping stopped .(Maybe I was using to much liquid)
Just my 2 bobs worth , I would stay with the paper filters, and its a messy job cleaning and re-oiling the U/filter.
Regards
Alanc

I ran one on my rocky for years without a problem, and yeah the most common problem with them is that people are too heavy handed with the oil on them, two teaspoons is all you need.

Used a Unifilter on a 60 series we used to have. Found a fine film of dust in intake hose most times. Living in a hot dry climate made the water based oil I used, dry out, as vehicle wasn't used regularly.
Have just bought a K& N filter, though I 'll probably only use it for trips on bitumen. K & N even make a comment about using such filters in "fine" dust conditions.
Heavy earthmoving equipment, such as Caterpillar, use paper elements. 'Nuff said.
From a few years working with such equipment, and comments on this
forum, feel some people clean their elements too much, often introducing dust into the system when the element is removed. Paper elements can take huge amounts of dust, before becoming restrictive.
Hooroo...

Yeah, you're right, the instructions say that you should rotate it reguarly if the vehicle is not being used much, otherwise the oil can seep to the bottom of the filter and that would probally explain you getting dust in there.

I think the problems associated with these types of filters are generally caused by people's lack of maintenance, understanding or of reading the instructions.
The main points I belive are:
1. Not rotating when the vehicle is seldom used causing dryness and lack of filter performance. (why would you use one in a vehicle that doesn't do many ks???)
2. Over oiling, not reading the instructions as to the cleaning and re oiling procedures.
I don't belive that these filters offer much more in performance, but they do deffinatally serve a purpose and they are good at filtering dust.
I think if you are the type of person who puts a filter in and forgets about it, then they are not for you. But if you are the type of person who
check's the filter reguarly I think they can work very
well.
Each to their own though, I love
mine.

Thanks people for the time you have taken with our query.
We will take all the advice on board before we make a decision to purchase or not, though the general concenous is that if you live in dusty conditions (we travel on dirt roads daily) then stick to paper filters!!!!!!!!!!
