SC-3200 Duct Fresh Spray Air Freshener, Deodorizer, Professional HVAC Odor Remover for House, Automotive, 32 fl oz, Clear

I bought this to eliminate a strong curry smell that we noticed when we moved into a new home. The smell was clearly embedded within the HVAC vents. I sprayed this into each return as well as the air filter on the HVAC unit and within an hour the smell was completely gone. I’ve since used the product in my cars and found it to be extremely effective. It leaves a very fresh smell that is not overpowering and instead neutralizes mold, mildew, and other unsavory smells. Highly recommend.

Excellent product. It isn't a "spray and fix forever" type of thing, but we noticed an immediate difference. Musty smell coming from the airhandler/through the vents turned into a very pleasant smell for a day or 2, neutral smell for 3 days, and then only slightly "off" for the next week or so before the original smell returned but at a lower strength.

This does have a strong scent - one other reviewer described it as "like a face full of baby powder". I don't use baby powder but to me it smells like the scent of the Febreze floor cleaner scent my wife uses. I'm hoping it smells the same way to her because otherwise when she gets home I'm in trouble since now the entire house smells of it and in general she has a low tolerance for scents especially anything floral. For whatever reason the Febreze stuff doesn't seem to bother her so I'm hoping I'm okay. Fingers crossed!That said it does seem extremely effective - we had a persistent "attic dust" smell every time we came home and I just had our ducts cleaned which reduced it maybe 90%. I squirted a small amount of this inside the main return duct and on the filter and the whole house smells of the scent. There's definitely no chance I could smell the residual "attic" smell. Applying scent to the filter is so effective I think even if I used it every single day I'd have more than a year supply but I somehow doubt that will be necessary. My $20 may have just bought me years of fresh duct smell.My bottle was shipped unsealed - there was tape around the neck of the bottle though - so you will be able to discern the scent without even using it. I suggest you let the most scent sensitive member of your household sniff it before applying and return unused if they find it unacceptable. I see other "no scent" odor eliminators but none say they are good for ducts. However I would imagine there's not really anything special about a duct freshener vs. any other. If you mist (as fine as possible) this or any product into the return duct while the A/C is running it's going to be distributed through the system, rinse and repeat. If you have any standalone air purifiers I think the same applies.If my wife does not freak out over the scent when she gets home I will spray it into my other return and report back in a week or so on how the scent and odor situation is. After all the idea is this neutralizes not masks odor. If there is no report back from me please call the authorities because I'm probably still locked up in the basement as punishment for stinking up the house :-)

It took away the musty smell almost instantly. It may be an acquired smell for some, but I like it! Wish I got this a long time ago! Much better than the musty smell from before. And seems to remove and not just mask. Let see how it performs a few days from now. Also like that it says it’s not toxic. It is a bit strong at first, so maybe do it at a time that you may leave the house for a little bit. Recommend!!

I have issues with a lot of scents and was hoping this would eliminate odors without adding some sort of annoying scent that would bug my sensitive self. I've got chemical sensitivity so I'm really sensitive and this does not smell horrible but smells sort of like baby powder and it gives me the feeling in my mouth like someone just squeezed a bottle of baby powder.It's possible that it's just me and everyone else thinks this smells great. Maybe it will dissipate in a few days and leave the house smelling just cleaner but so far I won't be spraying this in my vents again. We have two systems and I just sprayed it into the intake for the downstairs first because I did not want to get it in the one where I sleep until I knew how I would like it. I think I will pass on doing it in the upstairs based on my experience with the downstairs.Also an aerosol would make better sense rather than a spray bottle if you want this to trully travel through your air vents.I still gave it 3 stars because I realize a big part of my reaction could be my chemical sensitivities. It's too bad they do not make a sample size spray to send out so people could try first before buying a huge bottleThanks for reading my reviewBecky Brooks

Do you own a vacuum cleaner with replaceable filters???Vacuuming and freshening the air at the same time is a great idea.But, Febreze vacuum filters are expensive$$$.The knock-offs don't fit as well and their Febreze-like scent fades fast.** Try this idea. **Get SimpleAir's Duct Fresh Spray and put a few squirts into the air hose of your vacuum.The air freshening effect is *immediate* and lasts 2 vacuuming sessions.It works better than Febreze and is certainly more cost effective.My family likes the scent. It is more fresh than floral and I like it that way.BTW, I find it satisfying and more productive to freshen the air with the vacuum rather than the A/C.My A/C air handlers are in the attic so getting to those air filters is a chore especially in the summer.Hope you find this helpful.
