3-Pack, Nu Calgon/Clean Air 61060 Residential Odor Neutralizer/Block

I have had a dusty musty smell coming from my vents since we moved in 8 months ago. It's gotten so bad that I can't even relax without being partially disgusted. After buying an air purifier, every fragrance in the book, and bombing the whole house numerous times, I was absolutely sure nothing was going to work. THESE ACTUALLY WORK. I was super apprehensive about the price but after installing 2 days ago, I can finally say I just came home to a house without a bad smell. These have a very light pleasant odor but mostly they just seem to have obliterated the bad smell. Here's hoping they kill it over the next couple of months so I don't have to spend the money again.

Had a musty mildew issue when the A/C was running full blast in humid south Texas. Placed two of these in the air handler and the house smells like bliss! These will freshen up your ducts and deodorize as well! Very impressed and will buy again!!

I love this product! I purchased an older home that had sat empty for 5 years. I tried everything to get rid of the weird smell. I did some research and this product popped up. This product is easy to use and works great!! No more weird smell!!! I will continue to purchase Highly recommend

This actually worked for my 1 bedroom apartment. Scent lasted for a couple of weeks. It's been 2 months since installing this and most of the musty apartment smell hasn't returned yet. Highly recommend.

Smoke odor

This product has not done a thing!! It is like we didn’t have it at all. I keep my home extremely clean and was hoping this product would clean the air Don’t waste your time or money!!

This does not eliminate odor. It kind of blocks your nose from smelling anything. Nevertheless, I’ve had a hose full of animals and it has always kept the place from smelling like dog; it works really well.
