Mini Circle Collar Air Vent Grille Door Ventilation Cover White Color 4pcs

The hole size is a little bigger than the 1 1/2” it says. I would say more like 1 9/16” But we all know hole drills don’t come in this size, so I had to rem it out a little. This is ok because it doesn’t show when you are finished. Hopefully this will move air in a musky smelling closet.Very easy to install when hole is done. Sturdiness is remarkable considering it’s hard plastic. I will buy more if it works as good as it looks.

Not bad, an interesting idea. They do allow more air to vent. I am on the fence as to whether or not I will purchase more. The problem is I could just drill the holes and install rubber grommets from my local hardware store instead. The only difference would be the color and the lack of a mesh "filter". The filter seems unnecessary unless you have lots of pet hair. Even then you would need to clean them out from time to time.If you install them cleanly on a white door they look good and blend in.

These are perfect for a closet we have under our stairs where we have some media equipment running. The closet is not ventilated and was getting very hot. These helped to ventilate the room and keep it warm vs hot. These were easy to install and look great. I used a 1-3/4 drill bit which is slightly larger than needed... maybe 1-5/8 would be the right size (I wish the description gave better details).

They work! They are a bit smaller than I thought. About and inch -an inch an a half around.

Used them to provide air flow to my utility room in the basement. Easy to install and blends in well with the doors when installed.

These help bring fresh air into my heating room. Heating man wanted to charge me thousands to bring fresh air in these did it no problem...

It was on point for the purpose I wanted. However, did not fit the door I had as it was not standard thickness. So, I shimmed on the side that did not show and wala works great.

I installed these on my bathroom door. The exhaust fan pulled more air than the door allowed, these made for an easy fix!

These little vents have been working surprisingly well. We were having trouble with lack of air flow and mould in a room where we need to keep the door closed and the vents have made a huge difference so far.

Its OK. 20 dollar seems just too expensive for what it is.

Looks absolutely fine but the dimensions are no way near for the drill bit required. It’s states 28mm but actually looks 40mm - we shall see when the 40mm bit arrives! Anyone want a 28mm bit - only used once!!!

Used these to creat air circulation in our bedrooms. Return vent is in the hallway. Worked great.

It does not fit the size of an imperial 1 - 5/16 inch door. This is for thicker doors. It leaves a gap after complete assembly (pressed) on the door. I have to use silicone to hold it. Losing money on such materials. The shipping cost exceeds the value of the product. I will never buy again. Very disappointed.
