  • 3-PACK DUCT AID HVAC AIR DEODORIZER FOGGER This bundle includes 3 cans of Duct Aid HVAC air deodorizer mold treatment fogger plus 3 scented O-ring wool pads for continued odor management. Designed for use through HVAC return vents or as a targeted fogger in problem areas, it supports fresh-smelling air in homes, offices, RVs, vehicles, and commercial spaces.

Description

Duct Aid’s 3-pack HVAC air deodorizer mold treatment fogger with scented O-ring pads is a complete air-freshening system designed for use in air ducts, vents, and living spaces. Rather than masking odors, this plant-based fogger with thymol is formulated to address odor-causing elements present in the air and on surfaces inside HVAC systems and rooms. Each can releases a water-based fog that slowly settles through the air instead of dropping straight to the floor. As it moves, it comes into contact with microscopic airborne particles associated with musty odors, smoke residue, damp environments, pets, trash areas, basements, closets, cooking smells, and vehicle interiors. This process supports a cleaner, fresher indoor air experience across homes, offices, RVs, and commercial spaces. Designed for use as both an air duct freshener and HVAC air deodorizer, Duct Aid can be applied through the HVAC return vent for whole-home treatment. With the optional stay-on switch and stick-to-the-wall applicator, the can may be positioned near or inside the return vent, allowing the fog to circulate naturally through the duct system. Each can treats up to 3,000 square feet, making this 3-pack suitable for ongoing maintenance over several months. This bundle also includes 3 scented O-ring wool pads infused with natural oils. The pads fit securely into the green cap of the Duct Aid canister and release a subtle fragrance as air flows through the vents. Lavender offers a calming note, Pine provides a crisp outdoor feel, and Lemon Verbena adds a bright, fresh finish. The resealable packaging helps maintain fragrance strength between uses, allowing you to rotate scents as desired. For best results, use Duct Aid every 1–3 months, ideally when changing your HVAC air filter, and refresh the scented O-rings as needed. Whether maintaining everyday freshness or managing persistent household and vehicle odors, Duct Aid HVAC air deodorizer fogger 3-pack with scented pads provides a simple, plant-based approach to cleaner-smelling air.

    • DuctAid REALLY WORKS
Color: Green
This product is really amazing. Nothing like air fresheners that you buy at the grocery store that only last a few hours at best. It is easy to use. I just put my HVAC on auto, closing the vents where the air comes out and sprayed about half a can in the intake vent of my HVAC. Five days later and my place still smells terrific! ... show more

    • Great Scent, Works, Horrible Spray!
Color: Green
Update: 9/28/23 Below will be the original review. I wanted to give an update. The manufacturer reached out to me which was great and amazing customer service, they offered an apology and also offered a refund and in stead I asked for them to send me a new one. Which they did, and I was excited to see if there was going to be a difference in what was my complaint and issue with it and there was. The trigger was fixed and there was no leak when I sprayed it. Now, my new issue is the scent was weaker than the first one I had purchased. It sprayed better, but this new can felt lighter then the original. The first can that I recieved which had issues had a stronger scent that really filled the room and also filled the AC vents. The new one barley did the same. I'm still not giving up on this company, they have an amazing product, they just need to really focus on fixing the consistency of it. _----_--------------------------------------------------- Original review: I see many people complaining about the price, and I will never understand why anyone complains about price after paying the price! This product works, but there are issues. I bought a house that is a hundred years old, although renovated, it still has that old house smell. I became tired of using plug in fresheners and decided to give this a try. First, read the instructions carefully. When using in the HVAC system, you must have the fan on and not the heat or AC on. I used a little in the HVAC system and the scent spread through the entire system. Although the scent didn't last long, it did make the air coming from the HVAC system seem fresher and cleaner. I then used it in the rooms that had the strongest scent of old house, I sprayed the corners of the walls, I sprayed the center of the room including the light fixtures. Now, the second I started spraying it, it was dripping liquid. And when you turn it to the side to spray it at an angle, the air escapes more than the liquid. So this can is best to be used upright. Now, I only got to use half of the can and all of the air was used and there was a lot of liquid left in the can and it just stopped spraying. I believe in this product because it really did work, a week later and the smell of old house was much lighter, makes me think what would have happened if I was able to use the entire can. So with that said, the sprayer is the issue completely, there is no durability in the scent as it dissipated in less than an hour, but for some reason I don't think it's meant to last long. This product does indeed work, they just need to fix the flaw that the can and sprayer has. I would give them a chance when they have a new and improved sprayer. ... show more

    • Ductaid: Because Who Doesn’t Want Their House to Smell Like a Perfume Store on Fire?"
Color: Green
If you’ve ever thought, “You know what my house needs? A nauseatingly strong perfume scent that makes me question my life choices,” then boy, do I have the product for you! I bought Ductaid thinking it would freshen up my HVAC system and make my house smell nice. Instead, it launched an olfactory assault so potent that even my dog refused to come inside. Imagine someone broke into your house and sprayed every bad perfume from a discount rack—then cranked up the heat to bake the scent into every fiber of your being. That’s Ductaid in a nutshell. The smell is like a mix between a floral candle factory explosion and cheap cologne from a gas station. It doesn’t fade, oh no, it intensifies—as if it feeds off your despair. My house now smells like it’s constantly hosting a middle school dance mixed with martial arts exposition. Nice - right? To make matters worse, this wasn’t just a scent problem. Whatever Ductaid did to my ducts actually made my HVAC system less efficient. Now my vents are a superhighway of misery, spreading the stench room by room. Save yourself, your family, your pets, your nose, and possibly your neighbors nose. Ductaid isn’t a product—it’s a cruel prank disguised as home improvement. I would give it zero stars if I could, but here we are. I guess I’ll just go live outside now. Final verdict: 1 star for sheer audacity to make a product so awful! ... show more

    • It works, glad I ignored bad reviews!
Color: Green
Does what it says it does. And for the cry babies complaining about the scent. It basically smells like a floral perfume. Small price to pay for eliminating nasty odors and mold while improving your air health. Stop being giant toddlers.

    • Excellent product
Color: Pack 4
We bought a 4 pack Duct Aid for my 2900 square foot home. Not to mention that this is a 2 story residence. I have 2 kids that think there are professional cooks. The constant burning of food is a tradition in this home. I use to buy room Fresheners by the box, no kidding. Not to mentioned the extra exercise I am getting from waking to the second floor to deodorize the entire house. I use the product in my HVAC according to the instructions. It got rid of the smell with one can. What a game changer. No more walking up and down to get rid of the burning smells. The only thing I miss is my exercise. So I joined the gym. I definitely recommend Duct Aid. From a happy customer. ... show more

    • Very Strong Scent, But Doesn’t Last Long
Color: Green
This Air Freshener for HVAC Systems definitely has a very stout, powerful smell right out of the box. The thyme extract gives it a natural, herbal scent that quickly fills the space, which may be too strong for some people at first. While the initial fragrance is noticeable, it didn’t last nearly as long as I expected. After a short time, the scent faded significantly, especially when used in an HVAC system. It works fine for a quick refresh but doesn’t provide long-lasting freshness. Overall, it’s an okay product if you want an immediate, natural-smelling burst of fragrance, but it may not be the best choice if you’re looking for something that lasts. ... show more
