I purchased a K&N 33-2238 Air Filter for my Toro SR4 Super Recycler Mower 21 inch. So I don't have to keep buying paper filters. Wash it let it dry & reinstall. Have K&N Air Filters in everything I own. It's a no brainer better performance and never have to buy a filter again.

I ordered a No.33-2238 hybrid filter for my Toro Recycler Personal Pace walk behind lawn mower because the OEM paper filters were getting so dirty that I was replacing them about 3 times per season. I use the mower for mulching leaves as well as mowing the grass, so it gets a lot of use. The K&N filter fit perfectly, and the engine ran like new. I'm looking forward to cleaning the filter as necessary and just reinstalling it again instead of spending $10 for a new one about three times each season.

I've been using K&N filters on my 4 vehicles for a number of years. The cars breathe more easily with K&N filters installed. This one is for equipment I use in the woods under dusty conditions. The original filter needed replacement and hopefully I'll get the same or better performance out of the K&N replacement. The filter arrived quickly and fit perfectly.

Outstanding service in receiving the new filter for my small engine lawnmower. Superb quality and great replacement for my other filter. Love these K&N filters.

Aside from the superiority of K&N air filters, putting one in my mower just makes financial sense. Each disposable filter costs around $10 and I use no fewer than three of them each Summer and sometimes more than that. It's a no brainer to buy the K&N filter for less than one Summer's worth of air filters and never have to buy another. I use your filters in my motorcycles on and off the track and in my truck, and wouldn't consider any other product. What do I think about K&N air filters? I think you should keep up the good work.
