I have no idea. I have my car for 3 years now. this is the first time i replace it because the dealer said it was dirty. they where going to charge me and arm and leg so i went and bouth this replacement and did it myself. I would say everytime you change your engine oil check this filter and change it when it looks dirty.

The manuel says 15,000 miles or 18 months. If you have a Toyota Sienna you can google how to replace it and you should find short videos to instruct you. Not that difficult and saves a bunch of money compared to the dealer. They quoted me $120.00 to do the cabin and engine filters. The engine filter took about a minute and the cabin on about 5 (its in the glove box) again google it how to.

Well, that all depends on your usage... I have used one of these weekly for about 5 yrs and it shows no sign of wearing out.

No I have not had to replace it. It still works well. Also purchased one for a friend.

Depends on the conditions to your particular environment. Mine can make it to about 6 months, but I change every 3-6, depending how dirty it looks when I check it periodically.

I change mine about every 6 months, but I only use it at work. It doesn't get everyday or all day use.

I've had it over a year. I use it at least once a day, usually more. Have not changed them yet.

I replace mine once a year. A lot depends on how clean your house is and if you have pets that shed hair. I have two cats.

It depends on how much you use it. Mine lasted a lot longer than 2 years. But I used it even after they become somewhat worn. The replacements were very easy to install and work great.

We change ours once a year. Not sure if that is what is recommended though...

It can last 4+ years if properly maintained which is clear that you are doing. Great Job. We do recommend that after 10 yrs you do replace it proactively. You can call our customer support line at 800.9910.0466 ext 3 if you are in need of further assistance

I really depends on how much you use it obviously. My 1st one made it 5 years and I used it at least once a week

You are better off just getting a new one when needed because you have to be careful on how and where you store them. Best rule of thumb is to change them every 3 years with a fresh new battery.

A few weeks, I think they suggest replacing it every two weeks, but I've used it for six weeks with no complaints from my pup. Depends on weather and usage I would guess also.

Sorry to say I don't know because I've never had to replace mine. 5 months later & mine still works like new.

Sure, you can clean and reuse...in the manual it states that you must replace them every two months
