Wow! If they make this for your car BUY IT!
Style: HCC2122-X
I was surprised to see a reusable cabin air filter listing for my car. I didn't know such a thing existed. And they're the same price as a name brand disposable. I hate sending things off to the landfill, so being able to wash and re-use this, even if it breaks down after a few washings, is still saving the landfill and my pocket book. Quality feels excellent. Fit is tight, but with a bit of persistence it squeezes in. Sure, I realize this won't have the same micron level as a disposable, but, I routinely open doors and windows, and these filters area about catching the big stuff for me - not the molecules I can't see and get blown in as I enter/exit anyway. Super quality piece, I wish there was a fitment available for all my cars. I'm definitely keeping my eye out!

Size fit, well made and washable!!!
Style: HCC1017-X
After buying filters for ever, I came across this product. Well, why not? Washable? I got two so I can use the other after washing one. The filter fit inside the holder, it was a bit tight but fit for my 2006 Toyota Highlander. It is definitely more dense than regular filters, very well made. I will be looking now for a washable engine filter too.

2 piece filters but perfect fit
Style: HCC2143-X
It's a 2 piece filter, which seems strange but...the 2 filters fit perfectly side by side. Both filters have a loop to help with removal for cleaning. Just installed and haven't driven or used a/c yet. Hopefully the filters breath well.
