OdorStop Flexible Duct in Various Sizes and Lengths with Connecting Belt, 4-in by 25-ft

Well we gassed our selves out of the whse running a crane indoors, even with large overhead doors and man doors open. So we found an 16" exhaust fan and needed some extensions. So we bought these. Priced cheaper than others, but the quality is there! Made of pvc plastic and the coupling collars act as storage for the collapsed duct hose, nice feature. Handle all the air that fan could put out. We placed fan at crane exhaust and ran 75 feet of duct to the man door. Wow, what a difference! We didn't kill everyone by gassing them. They compact easily and almost to the same size as when they were shipped. Would definitely buy again!

This hose seems to be made well & very sturdy. It’s nice to have the bag feature & the 8” hose fits right inside this 16” one.I bought these hoses to work with the Alorair air scrubber & they attach decent. The latching belt system used to attach the hoses to the unit could have been engineered better. If the latches fail you can still use hose clamps.

As far as air hoses go, what can I say. This is pretty decent. There is a fairly nice tightening strap to clamp it on to the air cleaner exhaust. It seems a bit light weight and I'm wondering how long it will last.Recommendation to designer/mfger: Add loops to the hose so it can be hung and tied at the end outside a window for example.

Works great. Second one I have bought.

These ducts are a life saver, with many uses. If you are a contractor - it’s obvious. Clean air means clean home for home owners. I use them for grinding concrete before applying epoxy coatings. They work great for pushing dust out, as well as placing outside to bring fresh air in. I have the 12” and a couple 14” models. They both fit on a rigid air handler without problems (although the 12” is a little tight, it works with some patience).They rinse off with a garden hose and fold nicely to use again. Be careful with the ropes on the bag, they tear the vinyl easy if you pull to hard!

Sturdy, well built and work as advertised

This is a great product. Do not let the complaints about the built in bag in many of the reviews make you consider another duct system. The bag is big enough and it is not hard to get the duct back into the built in bag. That said, the rope tie does not work because the vinyl is too thick and stiff to close with a rope. I just purchased two Velcro straps to hold the duct in the bag, works great This is a great product, especially for the money.As noted in a number of the reviews, purchase the duct which is one size larger than your fan. I have a 14 inch fan and the 14 inch duct would not fit on my fan. The 16 inch fit perfect.

Easy to use and hook up to our air scrubber to create a negative pressure area in the space during remodeling.
