Aspen Snow-Cool Evaporative Cooler Fresher Air Deodorizer Cake

No odors from my evaporative cooler. I can't sy there was odor before, but they're cheap and fit in the reservoir easily. After I discovered they dissolve I started securing them in a mesh basket so the water stayed particle free.

This really helped with the smells that my swamp cooler. We don't have a reason as to what causing the smell since it was the beginning of summer and we had new filters, and the machine was clean. Super happy I found this.

This worked well for me to keep odors down.

This product was not usable when it arrived. It was discolored - moldy - on the top, and broken into several pieces. We were told it contains hazardous substances - afterward. We cannot use it in this condition.

Used to be less money

This is really good stuff, if you have let your swamp cooler get a little off doing maintenance, this really helps. If you regularly servicing your unit this is great, really effects the smell not perfume, just clean neutral, not noticeable, that's why I like it. I don't write stuff about products unless they stand out and do what they say they do; that's unusual now a days; used to be a law, things about false advertising and enforcement of laws; now we are on our own. Now a days you can say anything, and shoot for the moon; these guys did not over state this product, I have it in repeating during the summer, my swamp coolers pretty much runs from sun up till a few hours hours after sunset, I live in the Mojave Desert my big unit is over 20 years old, but in great condition I keep it that way. My smaller unit is all automatic witch is a bummer, both units this makes a big difference. I don't photograph stuff like a swamp cooler, so no pic!

The smell coming out of our rooftop evap cooler was nauseating it was horrible I couldn't even turn it on because it smelled so bad so after changing the pads rinsing out the pan we added this block and it really actually made a huge difference because we've cleaned the pads changed the pads cleaned out the pan before and it's still stunk now it smells normal I'm actually pretty impressed.

As promised the product helped with the smell of the swamp cooler
