I would have returned them but I bought them 1 year ago but just installed them 2 months ago. ### ⭐⭐⭐⭐⭐ Great Radon Removal Solution *by on Reviewed in the United States 15 June 2025* When we were about to sell our house, the buyer insisted on having a Radon test performed. We have never had any testing, nor an inkling that Radon was even present in our location, as no-one around here tests for Radon. When the readings, over a 4-day period, revealed radon in the 3 range, we were amazed, although not alarmed, as under 4 is not even guaranteed by the removal companies. Being proactive, we bought from Amazon, a Hound 3699 Radon detector and placed it in numerous rooms of the house. All rooms tested under 4, but the crawl space readings meandered between 3 & 6. I read the reviews regarding this fan and decided to give it a try, exhausting crawlspace air with all other vents closed, WOW! After only one day, readings in the crawlspace now are consistently under 2. Upon first plugging in, the unit produced a sound just like a drone taking off. I was concerned that the sound would/could be annoying, but once installed, in the crawlspace, under the insulated floor, the fan cannot be heard. If you are within 2-3 feet of the outside vent, the sound produced is akin to a clothes dryer. I am extremely pleased with this purchase!UPDATE: upon moving the radon measuring unit from the crawlspace to the living area, the Radon reading is coming in around .78 *WOW*!! This fan does its job!!One week update: Readings now sub-1, measuring between .20 and .673November 2025 update: The living area of the house now reads under .50pCiL 24/7I let the fan run continuously with a temperature reading of 60/61 with relative humidity averaging 45%I have radiant floor heating (boiler operated) and I detect no additional increase in energy usage and no effect on the tile floors. The crawlspace floor is covered with visqueen and the floor is insulated with fiberglass batting.Winters can be brutal here, so I will update if I run into any issues. So far, is it in the 30's. ### ⭐⭐⭐⭐⭐ Foundation twin fan vent *by on Reviewed in the United States 9 August 2025* Appears to be well made, quiet operation, installed in vent, in garage, went to opposite end of house, can feel it pulling air in, 52 ft, from fans ## Frequently Bought Together - Durablow 220 CFM Air-Out Stainless Steel Crawl Space Vent Fan, Dual Fans, Foundation Vent, Radon Mitigation, for Crawl Space, Basement, with Freeze Protection Thermostat (Stainless steel, M2) - AC Infinity Flexible 6-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust - Amico 12 Pack 7 Inch 5CCT Ultra-Thin LED Canless Recessed Ceiling Light with Junction Box, 2700K/3000K/3500K/4000K/5000K Selectable, 15W=100W, 1300LM High Brightness, Dimmable Wafer Downlight-ETL&FCC --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/649634088-durablow-stainless-steel-crawl-space-foundation-fan-ventilator-built-in](https://www.desertcart.sn/products/649634088-durablow-stainless-steel-crawl-space-foundation-fan-ventilator-built-in) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-11*
