Ventilaider Vent Filter Set 20" x 84" Electrostatic Media + 126" of Tape

Good filter, already changed few times.

Very cheap material, Velcro tape does not hold. For the price of this product does not meet expectations, quality is very poor

Although a bit expensive, it does a good job at protecting the rooms from dirt coming out of the AC ducts that is easily visible as the sheets start to turn black on the inside. The velcro tape is not that long so you may need to purchase additional. I recommend to put velcro tape all around the vent without any spacing to ensure that no air is escaping around the sheet.

It’s effective for the AC filters, make sure you replace it each month ... keeps the air clean

It does not hold as it should but we managed to use it somewhat.

its very good way to filter dust

I have installed it on my air vents for the past 2 months and it is effective in stopping dust from entering my room from the AC vents but at the cost of a roughly 50% reduction in the airflow. How did I conclude this? because it got a lot hotter when it was attached. And just today I removed the 2 month old filter and was going to attach a clean one. Whilst installing the clean one; I used my palm to check how much air flow was passing through with and without the filter. I was shocked that about 50% of the air was also being blocked. So I would accept some dust to enter as long as I can get 100% of the cold air from the AC vents. btw, I also ready have the fan speed turned to the maximum.Overall you can use it if you have intense dust coming our of the vents; but if this was the case I'd look for a AC duct cleaning service instead.I will not be using this filter anymore and I will repurpose this filter for maybe something else.

Easy to apply on the vents
