00:00Alright, let's talk about something that drives me absolutely nuts in my own house,
00:04that cold draft and funky smell creeping back through your exhaust vent when the fan's off.
00:08I went down a rabbit hole looking for the best fix, and I found the top 5 duct check valves
00:13stopping backdraft air. These are the actual best sellers, real reviews, real prices,
00:18so stick around because number 2 is stupid cheap. First up, the 1PC Durable Plastic Pipe Check
00:25Valve and honestly, this one's popular for a reason. It comes in 80, 100, 110, 150,
00:32and even 200mm sizes, so it'll fit pretty much any standard kitchen duct setup you've got.
00:38The flap seals up tight when your fan stops, which means no cold air, no bugs,
00:42no neighbors cooking smell drifting back in. It's sitting at $5.37 with almost 4,900 sold
00:50and a 4.8 rating, that's a solid track record for something you'll install once and forget about.
00:55Now, coming in at just $2.07, the Pipe Draft Blocker Backdraft Damper,
01:00this is the budget champion of the list, and it still holds a perfect 5-star rating with nearly
01:054,700 sold. It's built for inline extractor fans, so if you've got a booster fan in your
01:11duct run, this drops right in and does exactly what it says. Lightweight, simple, and for $2?
01:18If you're not sure about your sizing, just grab this one first. Honestly, at that price,
01:24you could buy two and not even feel it. Next, the PVC check valve for bathroom and
01:29kitchen ventilation fans at $4.33, this one's a 5-star favorite with over 4,300 sold, and I get
01:36why. It's specifically designed for exhaust fans, so the round backdraft damper is sized to sit
01:42flush against the fan housing and swing open with barely any airflow resistance.
01:47Translation? Your fan pushes air out just as easily as before, but nothing gets back in.
01:53If your bathroom fan's been letting in that musty outdoor air, this is the direct fix.
01:58Fourth on the list, the 80-150mm PVC Round Pipe Draft Blocker, $3.56, 4.8 stars, over 4,300
02:07sold.
02:09What I like here is the ventilation-grill combo, it's not just the one-way valve,
02:13you're getting a finished look for the wall or ceiling side too. So you're covering both the
02:18function and the appearance in one go, which saves you buying a separate grill. It's a really practical
02:24pick if you're finishing a renovation and want it to actually look clean. And last but definitely not
02:29least, the fan check valve with the widest size range on the list 80, 100, 110, 120, 150,
02:36and 200mm. That's the most options out of all 5, and it's only $4.52 with a perfect 5-star
02:44rating and
02:454,371 sold. It's designed for exhaust hose setups too, so if your ducting is flexible hose rather
02:52than rigid pipe, this is the one that'll actually fit properly. Great pick if you've measured twice
02:58and want zero guesswork. So there you go 5 solid options, all under 6 bucks, all doing the same
03:04important job, keeping that backdraft out of your home. All the links are down in the description
03:09below, so check your duct size before you order. If this helped you out, do me a favor,
