This is the absolute best air filter I have ever used. It's well done by the most famous air filter experts in the world and I don't expect too much from this great company. I have been using their filters in my cars and motorcycles for over 30 years. So, getting them for my home is a dream come true. The filter is a little heavy compared to cheap paper filters, so turn on the suction fan to hold it in place during installation or it will fall on your head while you're desperately trying to close the air intake cover levers. I washed it and it's very easy to do with soap and water. Initially the fit was a bit loose so I added rubber padding for weather protection. I think it will capture all kinds of dust, dirt and pollen for years. As an added benefit, fan and compressor noise coming from the air conditioning has been significantly reduced. Now, after all these years, rest! Air filter costs are out of control and it's just money well made that goes in the trash every 3-4 months. The money I saved with this filter will be back in 2 years! I will repeat it again. These are the BEST home air filters in the world! My size was 12x24. K&N Please make them in 14x14 and 16x30 and I'll give you 10 stars!
