I will never buy these air filters from Amazon again. I have bought this brand from various stores and have had no problems. This batch, which I recently bought from Amazon, is of terrible quality. The filter lasted 2.5 weeks and is so cheap and flimsy that every time the air/heater is turned on the filter sucks and bulges into the vent. It's so loud and woke me up every time it got hot at night. I asked my husband to change the filter because of this and when I took another filter out of the box I noticed that the filter didn't even have a permanent fiber coating and I could see through some parts! meaning it doesn't filter anything and the dust keeps blowing all over my house and into our faces. These filters are garbage. money thrown away. And he explains that there's been a lot of dust in the air lately and why everyone in my house has been coughing for the past few weeks and so on.
