I was expecting a reduction in odour. However, I was actually shocked and very pleasantly surprised to find absolutely ZERO odour coming out of this filter. It has literally 100% eliminated a stinky problem. I have it at the end of an exhaust pipe, with the pre filter bag inside the unit. A 12 volt 80mm fan has no trouble pushing air through it ### ⭐⭐⭐⭐⭐ It’s a filter! *by on Reviewed in the United States 11 March 2026* Well it’s a filter and it does its job but it’s AC infinity so it looks pretty too.This thing is sturdy and easy to clean or swap out the filter material so it’s a huge plus over my last one.It has a good seal against my AC infinity fan and they’re both super quiet together.Helps keep the stank in the grow room to an acceptable level - solid product from AC infinity as always! ## Frequently Bought Together - AC Infinity Air Carbon Filter 4" with Premium Australian Virgin Charcoal, for Inline Duct Fan, Odor Control, Hydroponics, Grow Rooms - AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust - AC Infinity CLOUDLINE PRO T4, Quiet 4” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/259547231-ac-infinity-air-carbon-filter-4-with-premium-australian-virgin](https://www.desertcart.pt/products/259547231-ac-infinity-air-carbon-filter-4-with-premium-australian-virgin) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-18*
