Title: Very poor quality
Review: Bought these based off some of the reviews thinking I was making a good choice. My vent is right outside my bedroom door and it whistles now. Luckily I have a hole BOX of these to get through...probably will toss them. Look for a better quality filter. It's worth the $ and hassle. The filter is thin, see through and not sure it's actually filtering much except the whistling sound.
