RX400h Posted March 23, 2008 Share Posted March 23, 2008 Yes, it was time to check out that cabin filter. Apparently, the dealership had mis-installed one of the quarter-turn glovebox travel-limiting pins, making it extremely hard for me to twist, but it weren't for that, removal and installation would've been a 3 minute job. I've attached a picture of what the old one looked like. I guess 15,000 miles is the LONGEST I will ever wait before changing the new one! Oh, the engine intake filter was also dirty, but not nearly as much as was the cabin filter. Dave Quote Link to comment Share on other sites More sharing options...

Gryphon Posted March 23, 2008 Share Posted March 23, 2008 I suspect that the longevity of cabin air filter is related to climate. Mine was merely dusty at 10,000 miles, but I live in a Arizona which is obviously quite dry. Tom Quote Link to comment Share on other sites More sharing options...
RX400h Posted March 23, 2008 Author Share Posted March 23, 2008 thats not too bad just changed my moms cabin filter on her RX and i looked like i scooped a pile of dirt off a forest floor. How many miles has the filter seen? I suspect that the longevity of cabin air filter is related to climate. Mine was merely dusty at 10,000 miles, but I live in a Arizona which is obviously quite dry. I would expect that dry weather would allow more dust and dirt to fly around and end up in the filter. It is relatively dry here in San Diego, but when it does rain, airborn dust and other particulates are temporaily vanquished. Quote Link to comment Share on other sites More sharing options...

Dave I personally have made it a practice to clean/replace the cabin air filter every 5,000 miles regardless of dealer/service locations functions at that time. I find checking and cleaning is pretty simple for the benefits gained. I keep a new one on hand in case the installed one is too dirty. If it is a 'little grey', that's okay after using vacuum cleaner and compressed air! Quote Link to comment Share on other sites More sharing options...
RX400h Posted March 25, 2008 Author Share Posted March 25, 2008 That's a good idea, although from what I recall, that small filter is certainly not inexpensive. This was the first time I changed it, myself and it was a lesson well learned! I will check the filter more often. Quote Link to comment Share on other sites More sharing options...
GDixon Posted March 25, 2008 Share Posted March 25, 2008 After reading this topic, I decided to check the cabin air filter in my RX350 - now at 10K miles. It was not horrible but was plenty dirty and so was replaced. It will be done every 10K miles from now on. At least the filter is doing its job by getting dirty so it can be viewed as a plus. Instead of running around your cabin area and getting into everyone's lungs, the gunk is getting caught up in the filter. I may try the suggestion on another post of buying a HVAC filter from Lowe's or Home Depot and cutting it to size. A bit of duct tape may be needed to seal the edges. If a large enough filter is purchased then several cut-outs can be made for even greater economy. It appears that the thickness of the filter will be the deciding factor. Taking in the old stock filter to compare is recommended. The little locking tabs on the sides of the glove box door were hard to turn the first time and pliers had to be used. Maybe they will loosen up the more they are used. For those of you who haven't done it before. There are two black plastic tabs that hold the glove box from opening too far that need to be rotated a quarter turn toward the passenger and then backed out a bit - a screwdriver may be needed to slide the tabs toward the center of the glove box. The glove box then drops down and a white drawer can be seen behind the glove box. It just pulls out to reveal the filter. The filter pops out and the new one pops in but look for the "UP" indicator on the new filter and the drawer. Replacement of the whole assembly is the opposite of removal. At least that is the procedure for the 08 RX350. Quote Link to comment Share on other sites More sharing options...

This was the first time I changed it, myself and it was a lesson well learned! I will check the filter more often. I failed to make another suggestion... I looked at the MAINT option on my display and found where to 'update' Cabin Air Filter maintenance and have set it to 5,000 miles and/or 6 months. This will cause you to get a message when that distance/time approaches! Nice to have a little 'support' for the maintenance effort! Quote Link to comment Share on other sites More sharing options...

One of the pastic screws is unmovable by hand and was afraid to use pliers.. guess that's next.. thanks again! Quote Link to comment Share on other sites More sharing options...
Gryphon Posted March 29, 2009 Share Posted March 29, 2009 The fasteners do come out pretty easily with flat-nose pliers. If you lube them with silicone grease they will come out by hand the next time. Tom Quote Link to comment Share on other sites More sharing options...
RX400h Posted April 1, 2009 Author Share Posted April 1, 2009 By the way, I was at Walmart the other day and noticed a new line of cabin filters that contain "odor-absorbing baking soda" . There was one listed for the RX400h so I opened the box and looked at it. Around the edge was a black foam strip that had shed small fragments into the clear plastic bag into which it was enclosed. When I saw that, I put the whole thing back on the shelf. It's price was about $17, but until something better comes along, I'll stick with the Lexus filter.

lenore Posted April 1, 2009 Share Posted April 1, 2009 I wash mine. Take them out clean with a vacuum and then wash with simple green. Rinse, let dry. Mine is 10years old on my RX and is still functioning. Quote Link to comment Share on other sites More sharing options...

Mine is 10years old on my RX and is still functioning. Are you sure there is no paper in it? Most disposable filters cannot be washed, as the paper media would break down. My cabin filter looks somewhat like certain home filters. I might vacuum one once, but would never think to wash it. Maybe you're on to something!

EDV Posted July 10, 2009 Share Posted July 10, 2009 Help Please!! Is the cabin filter the same thing as the Airconditioner filter the dealer wants to change for $80. Any help would be great. Thanks. Have a great weekend. Quote Link to comment Share on other sites More sharing options...
RX400h Posted July 12, 2009 Author Share Posted July 12, 2009 I believe that it IS the same. I suggest you replace it and the intake filter, yourself. Dave Quote Link to comment Share on other sites More sharing options...
Gryphon Posted July 13, 2009 Share Posted July 13, 2009 The OEM cabin air filter is definitely paper and does not wash well. There are several aftermarket brands, none of which I have seen in person, namely: Beck/Arnley WIX Fram ATP AC/Delco Bosch Tom Quote Link to comment Share on other sites More sharing options...

RX400h Posted July 16, 2009 Author Share Posted July 16, 2009 I buy mine from the dealer, since the aftermarket ones I examined were very lacking, qualitywise. The front of your RX has a cold air intake slot built-in from the factory. That slot allows cold outside air to be ingested by the engine's intake - a definite power advantage, since colder air is more dense, which means more air molecules can be crammed into the combustion chamber. When you open your hood, you'll see where this cold air path leads - straight to the filter. It is very easy to change. I'll be changing mine, shortly and can take a picture or two. dave Quote Link to comment Share on other sites More sharing options...
riwyle Posted July 16, 2009 Share Posted July 16, 2009 The cabin air filter is located behind the glove box. Remove the plastic stops which allows the glove box door to fully drop, providing access. I bought the filter at the local NAPA auto parts store. Cheaper than Lexus or Toyota. Could see no difference in quality from the O.E.M.
