All Natural Thymol Duct Aid - Organic HVAC Air Freshener & Odor Eliminator for Air Ducts & AC Vents | Pack of 4 | Perfect for Home, Office & Car Air Purification

I bought this product because there was an unpleasant odor emitting from my air duct system. It was easy to do and for the most part, the house was fresh. My only issue really is the price and the misguidance of the picture. I didn't read very clearly and expected two cans; why because it looked like 2 cans shown in the advertisement, but it's really 1, but turned around to show the label contents. Misguiding. So I paid 34 dollars for a small can of solution that really should've been 2 to cover a proper air duct system. Lysol might have done the same thing. I figuring now at 7.99 can. I might buy another because I do like the no-toxic fragrance and the push-down button, but the price will make me pause and reconsider, but give it a try; I did.I first heard about this product from a friend that recommended it so I decided to give it a try. I used it in my car‘s air-conditioning system and then at my home's air dock system and the change was unbelievable it worked fantastically. I recommend this product to whoever would like to sanitize and deodorize their air ducks!!I am very pleased with this product. I like the fresh scent and the fact that it kills germs and bacteria. Very simple to use and great packaging.My husband and I dislike fragrances. When I researched this product, the FAQs stated this product smelled like thyme. It does not. Any thyme is completely covered up and overpowered by a fragrance that is now everywhere in our house. It is horrible.I own a VRBO and was looking for something to refresh the ducts between professional cleaning, which usually occurs around every 3-5 years depending on whether or not one has pets. I like it! The house smells great, my only complaint is the scent, while pleasant, is a bit strong but does weaken as time goes by; I have severe asthma do wish they would make a scent free one but do understand that Thymol does have a scent. I will keep using this as it does what I need it to do, refresh, kills mold, germs, and bacteria. Off to buy the four pack! :-)
