I have bought many replacement filters and you must beware as many cheap Chinese fakes are half the width of the original foam part. I found this product and was thrilled it came on. However, the foam only tore a little after two months when rinsing. I've had the original filter for years, just replacing the accordion part with cheap fakes and reusing the foam. I had to as the new ones were twice as thin as the original foam. a bit disappointed but I haven't found a certified replacement filter that is as good as this one. To clean, I manually removed the hair and dust, then rinsed with water and air dried. I did this every 2 weeks.
