Review on 🌬️ SimpleAir Duct Fresh Gel - Non Toxic HVAC Air Freshener, Cleaner, Deodorizer for Odor Blocking in Small Spaces by Tammy Thomas

This product WORKS! FOLLOW THE INSTRUCTIONS! Worked wonders on a moldy, abandoned HVAC system in our new Florida home! Start with new filters. ALWAYS use the same manufacturer's spray FIRST on the air intake with the fan running to distribute it through the air ducts, then use over the air intake filter. Follow the directions and pour the gel block into a larger plastic container so all sides are exposed, otherwise it won't work properly! A bit pricey but nothing else worked, sewer cleaning is a bait and a racket, especially here in Florida! Try it!
