## Overview

The Nu-Calgon Residential Odor Neutralizer is a powerful, self-feeding odor eliminator designed for HVAC systems. Unlike air fresheners that mask smells, it chemically neutralizes a wide range of indoor odors including mold, pets, smoke, and musty dampness. Easy to install in air handlers or return ducts, each block lasts 6-8 months, delivering continuous fresh air and improved indoor air quality for homes up to 1800 sq ft.

## Description

This product has a unique clean air formula capable of eliminating indoor pollutants and odor-causing components. It eliminates odors caused by mold, mildew, bacteria, pets, smoke, musty odors, water damage, fire damage, paints, chemicals, animal decay, stale air, garbage areas, sewer gases, skunks, and more. Buy it and use it in A/C units, furnaces, rooftop units, fan coil units, and air handlers.

Review: STILL Eliminates Lingering Musty Odors - 2024 UPDATE: We had a mysterious chlorine-like smell outside an upstairs bedroom. We checked the upper zone air unit and the trunk line, but couldn’t locate a source. We changed the ceiling registers and thoroughly cleaned the room and hallway. We were renovating the bathroom and checked its walls and subfloor (the bathroom is right next to the bedroom with the odor). The smell lingered. In desperation, we used half (because of limited space) of a Nucalgon block in the upstairs ceiling cold air return compartment. Within 24 hours, the mysterious smell was gone. I’m always surprised at the bad reviews that complain the product doesn’t leave a scent. It’s an odor ELIMINATOR, not an air freshener. There are plenty of other things that will mask odors. This actually gets rid of them. Nothing compares to it. 2016 UPDATE: We have now used these in both our home, our rental property, and my daughter's home. She has a large breed dog and says that it is the only thing that will keep her house free of doggie odors. One block will clear the average 1600-1800 SF home for about 6-8 months. The powder "evaporates" (dissipates) over time. We use it primarily in the summer, when damp smells seem to be at their worst and humidity increases musty smells. We buy them every year and place them in the cold air return vents. REMEMBER TO DUMP THE CONTENTS IN THE BOX AND THROW AWAY THE PLASTIC. If you keep the powder in the plastic packaging (as one of our tenants did), it will not work. Wishing you all fresh smelling homes! ORIGINAL REVIEW IN 2013: We have had an extremely rainy spring and summer in the southeast this year. Every time I went downstairs there was a lingering musty smell in the downstairs hallway, which is where our cold air return opening is located. We replaced the filter, vacuumed out the entire area, ensured the vapor barrier under the house was intact, and tried various air fresheners to get rid of the musty, moldy smell. We tried this product figuring we had nothing to lose (I was considering calling one of the companies that come in to restore an area after a fire or flood to see if they could determine the cause and fix it). When this arrived in the mail, I was underwhelmed, and didn't think it would work. It is just compressed powder in a thin cardboard box, wrapped in plastic. First of all, you have to open the plastic bag it comes in and dump all of the material back into the box. Perhaps the reviewers who gave it a low score didn't follow this step. Personally, I found it to be a strange way to prepare the product for use, but we followed directions, put it in the cold air return, replaced the grille, and figured we would be greatly disappointed. Within hours, I went down the stairs and didn't notice anything. Nothing. Then it hit me. The lingering, musty smell that had plagued us for months had disappeared. Completely. Totally. If you are looking for something that has a "throw", or smells like fabric softener, fruit, vanilla, or flowers, this is not for you. All this leaves behind is odorless fresh air. A side benefit is that shortly after you cook something like fish, or fried food that normally leaves an odor behind, the smell is gone within an hour. Like it never even happened. I don't know what is in it...but it works. If you have an odor issue in the entire house and you have a dual zone HVAC, you will need to get two of these. We are considering getting a second one for our upstairs unit, just so the upstairs smells as outdoor fresh as the downstairs. Great product so far! The carton says it will last in a 5 ton system for two months. I'll write a follow-on to let you know how long it lasts.
Review: It works - When you get this the smell is very very strong. Don't worry about that. Once it's attached within your blower unit (we have a heat pump) you don't smell anything (or at least I didn't) in the home. Might take some skills to securely mount the unit so it is in the air flow but doesn't come loose. I find it lasts around a year. Kitchen smells, dog smells, etc. are quickly gone after a few minutes of air movement. Works well!

### ⭐⭐⭐⭐ Works great long term
*by A***Y on August 12, 2025*

Works great for units that have issues with smoking in them. I’ve bought this block about 8 times and stick them in the furnace to guarantee the smoke smell disappears.
