Ventilaider Complete Air Vent Register Filter Set Cut To Fit Any Size 16" x 60" & 50" Velcro Tape, Electrostatic Fabric. Purifies Air, Helps Reduce Allergies From Dusty Ducts, AC Furnace System (2)

I originally bought this for a hotel stay during Covid-19, I needed something easy to put on and remove when I checked out and it worked great. Now I'm using it to cover the vents in my house to keep the smoke from wildfires out as much as I can. I might keep a package of this at home always, just in case.

I use this item to cover a vented door that is in front of my A/C to add a little more filtering. It works great but I just found out, I can't buy it anymore as it's not listed on Amazon anymore. Bummer.

I didn’t realize these would be so big and need to e cut down to size but fairly easy to go. I bought two packs but could have definitely gotten away with just one. Seems to keep the dust at a minimum.

I added the filter to my handler return door to trap more dust and prevent it from entering the unit. It was very easy to install with the included velcro straps. I cut the pieces to cover the entire door, very easy. I created a pocket to place a camphor tablet and the air in the house smells really fresh.

this product didnt work as expected for us. I tore it in half so that it continued to allow air flow, but caught anything (hair, dust, dirt, etc) from circulating through the home. We applied it to a couple vents and replaced a month later, but we couldnt see anything on the filter. we tried to use it on the return air vents but it tore from the force of the air in the duct within the first day. oh well.

I’m not even going to try to use this. It’s not breathable at all and literally feels looks like felt you use for crafting. Return window got away from me so out of money and time. DONT BUY if you want your vent to be able to breath.

Cut this to fit and covered our ceiling air vents with it. We were having major dust issues but weren't ready to replace them. We needed to buy more adhesive than this came with but otherwise this stuff is amazing. No more dust.

I moved to Tx in 2011 and let me tell ya, I never had a dust problem in Fla. Mine is a home built in the 70's and I thought there might be a duct issue. I could dust one day and two days later, I could write my name on a table. This product is amazing !!!!!!
