K&N LIFETIME Cabin Air Filter: Premium, Washable, Clean Air for your Cabin: Compatible with Select 1997-2009 TOYOTA/LEXUS (Aristo, Altezza, Kluger, Highlander, IS 200, IS 300) VF2008

I have quite bad nasal allergies. So my home and my car are the only sanctuaries I have where I can breath clean filtered air in peace. I change my filters often because I run my air non-stop. The cheap paper replacement filters I've been buying all these years are flimsy and don't seem quite up to the task. Plus at $15 a piece, they quickly add up.Behold, this high performance reusable filter; my prayer has been answered. I have had numerous other K&N performance filter products in every vehicle that I own. So naturally I had high expectations for this filter. I've only had this installed for a few days. But here are what my first impressions of this product.This filter is the EXACT shape of the plastic tray that came out of my Lexus' blower unit. The slight taper on the rubber sides even clears those little hooks formerly used to secure the paper filters in place. This filter fits snug. I expect no blow-by's, which is good.When I first turned on the air, there was a funky plastic smell. It was probably the smell from the rubber, but it quickly dissipated and did not bother me after that. My nose has been happy so far. That is a clear indicator that this filter is doing its job. This alone is worth the money.But just out of curiosity, I measured the airflow from the air vents with my anemometer. Indeed, I recorded a 1.2ft/s to 1.7ft/s increase in air velocity coming out of every vent vs. the old paper filter that I ditched. This is great because now I can move more air faster on those hot days requiring MAX AC. Or turn the fan way down for some quiet cruising when I don't need all that air.One thing however, is that I can not find any indication of the MERV rating on this filter, either on the packaging or K&N's website. Anyone with allergies will want to know if a certain filter will screen out the specific types of allergens he or she is allergic to. The MERV rating is perhaps the single most important spec for any filter, which will tell the user that information. Numerous of my email inquiries to K&N's customer service and PR department over a period of a month had been ignored. And that's the most frustrating part. This product may receive a 5-star rating from me, but K&N's customer service department receives a big fat zero.So I took a $40 gamble and bought this filter anyway without knowing it's efficiency. It has been working out for me so far. I'll buy the cleaning kit also to clean this filter in 6 months, then update this review if anything changes.Update 10/19/15:Still 5 stars!On several occasions, I purposefully followed some smelly diesel trucks with my vent open to the outside air. And I'm happy to report that this K&N filter is able to filter out the stink of diesel exhaust. I used to drive my car with my air on recirculate all the time because I hate the smell of diesel exhaust. Nothing is worse than having to endure the fumes while I'm already pissed off sitting in traffic. Now at least I have the option to swap out the air in my car if I want to. This product may actually help to preserve my ZEN and curb road rage.This leads me to deduce, that this filter probably has a MERV rating of at least 10; because that how fine a filter needs to be in order to filter out automotive emissions. Having made this new observation, I feel even better about my purchase, and I can now breath a lot easier. Pun intended.

Replaced my paper filter own wit this. Be sure to buy the K&N cabin air cleaner kit to clean this filter.

Have you seen the price of most cabin filters? They are outrageously priced. They are more expensive than an engine filter by a good measure. If I am to pay $27 for a disposable filter; good for 6-9 months, why would I not buy a washable/reusable filter for $40 good for ... well forever??Additionally, I am more likely to service a reusable filter more regularly than replacing a disposal filter.

Fit my 2002 Lexus is300 perfect.

Bought 2pcs at once same model. Came different packages (may old and new batch ? )In description written 10year/million mile, the other package written 10year 100.000mile.Can see 2nd photo i put near each otherPackages was damaged from under side, opened, one was opened from up also, can see 3rd photo show with finger, black color plumb damaged cuted...There is video , can upload all.How this understand??

I liked the fact that I have a filter that is supposed to last the lifetime of my vehicle.At a higher initial cost it will make up for the cost of replacing one each year.

I would think that just about everyone know about K&N filters well now, they make automobile cabin filters that do a fantastic job and they are reusable. No more buying a new filter from your local dealer or automobile store at whatever the going rate is.

Well structured and put together product
