I only received one filter, but paid for two.  Please reimburse me for the other or credit my debit card.

When I finally got around to replacing the filter, long after the return window closed, I discovered that I had ordered the wrong filter. It turns out that there is a 211+, not a 211, that takes a different filter than the 211, my version. This is an expensive mistake as the 211 is a product that works. Why in the hell the company doesn't label a different product differently in number is beyond my pay grade.

Ordered these filters and they came from the supplier in a timely fashion. Good price for 2 filters.  Did order the MERV 11 size and received a MERV 13.  Got upset at first and then did some research on what a "MERV" actually means.  The higher the MERV the better the filter.  The higher the number the more restrictive the filter is trapping all and extra airborn crud.  Have to replace more often, but hey ya feel better.  So it's a win win in my book, will always order a 13 MERV FROM NOW ON. SO WHAT I THOUGHT WAS A SCREW UP ACTUALLY TAUGHT ME SOMETHING NEW.  The screw up was better than what was originally purchased...when does that happen!!!

These filters are very nice, and look sharp on my GS750. This would have been a 5 star review, except for 2 small issues I had with the shipped product. 1st, one of the 4 filters was different than the others. The chrome cap on the end with the K&N logo was upside down. This isn't a huge issue, I just used it as one of the middle filters. I would just have assumed that for the money I was paying, quality control should have been a little tighter. The other issue I had was the return/replace policy. I didn't open these up right away, because I wasn't going to need them right away. This turned out to be a mistake given the issue with the single filter. By the time I noticed the issue, the short time frame for returning or replacing them had lapsed. So unless K&N is willing to replace them, I may be stuck with it. Neither of these issues are really that big of a deal, but i did feel that in my case it was enough to deduct a star. Regardless, i highly recommend these filters as a replacement for stock air boxes or as an alternative to the dime a dozen pods you see on every other bike. Be warned, you absolutely will have to rejet your carbs with these filters.

I wish you could order the filters individually, but nevertheless these work like a champ. I have pets so I have to replace mine more often.

I ordered this product and upon arrival I discovered it was a 46mm filter when I ordered a 49mm filter. I immediately contacted Amazon about the situation. They apologized about the error and began to fix the problem. I had to pay out of pocket for a new filter, but was refunded full price including shipping and handling when Amazon sent UPS to picked the incorrect product(46mm filter). They then offered one day shipping for free on my new order. I just received it and I am very pleased with the customer service and how they handled everything. It arrived on time, packaged nicely, and clean filter. Now I am ready to go out and take pictures on the brightest days with my new filter.

One of the two filters leaked badly the first time I installed it.  I had to remove it and re-install it 3 times before it sealed up properly.  The second filter fit fine.

I really have not had a chance to use all of them but I am happy with  the two that I did try. This is my first try with filters and it will probably take multiple attempts before I start getting really good results.

These are the filters I normally use. The filters are great. The fact that it was a pack of 6 that didn't have each filter individually wrapped was a bad idea. Now I have 5 unwrapped filters that I have to find a clean and dry place to keep them

Filters work well and are a more inexpensive alternative to the ones that the heating/cooling companies want to sell you.  Enough filters to last a year or more.  When the product delivered I couldn't find it so I contacted the company.  They determined it must have been stolen off the doorstep.  They were great and sent a replacement.  The product and company are great and I would order again.

I thought I ordered the newer filters but I received the old filters.  On the box it looked like the new filters.

One of the filters I received was defective and of course I couldn't return it because I didn't know of the defect until I had to replace the second (defective) filter until six months later!

Last time I ordered filters they were a perfect replacement. This time they were incorrect. I made them work for now but will be more careful next time.
