It was quite easy to install and came with all the hardware needed, including four thin foam strips with sticky tape on one side that made the installation more professional and allowed for a nice, tight fit. Following the instructions, it was quite easy to connect the device to my home Wi-Fi and the app set up was quick and easy. Once the device is added to the app, you can turn it on/off and change the percentage of humidity at which you want the fan to automatically turn on. The CFM's are great for my purpose. Since we live in the desert, our garage gets quite hot when parking two cars in it (engine heat and ambient temperature). This fan has helped pull the hot air out, blowing it outside of our house, bringing fresh air into the garage as long as I have the fan turned on and it's working great. The installation took all of 10 minutes and the app set up took another five minutes. Quick and easy! Review: Great Radon Removal Solution - 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 desertcart, 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 .673 November 2025 update: The living area of the house now reads under .50pCiL 24/7 I 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. ## Features - ▼ WHY USE A VENTILATION FAN: A ventilation fan benefits your home in several ways: ▼ Reducing radon level in lower areas.▼Keeping your crawl space and foundation dry, guards against condensation, and vents harmful gases and odors. ▼Enhancing indoor and outdoor air quality, controls humidity.

The fans do 220 cfm or 13,200 cubic feet per hour, 13200/5 = 2640 cf so that's about 30'x30'x3' cubic feet of crawl space. Don't forget you need air intakes on the opposite side to allow fresh air to enter. If your space is a lot bigger than 2640 cf then you need two fans. I recommend putting the fan on a timer so that it turns off at night when the outside air tends to be higher humidity which you don't want to be pulled into your crawl space. Better yet a dawn to dusk timer would be very convenient. Also place the fan on the side opposite to the prevailing winds in your area;.that way nature will assist the fan most of the time to move more air. **Q: Water proof?** A: I don’t know if it’s completely waterproof, but it seems to be moisture proof. Mine gets wet and I haven’t had any problems. **Q: Are the fan grills stainless steel?** A: Real #304 Stainless Steel. Welcome test it with magnet. **Q: Would this be appropriate for use in a small utility room that houses a pottery kiln? I am concerned about chemical offgassing.** A: Dear Amazon Customer, First, this is a ventilator with Built-in Dehumidistat. But, I think it is suitable for your project/application, since it equips stainless steel #304 back panel / control board housing, and full aluminum blower frame for being corrosion resistant. For your use, please set a lower humidity level to keep power ON. Hope this helps. Thank you for your question and interest.

In our 1950s house with uninsulated walls and floors and heating kept around 68 F, this means indoor humidity can approach the ~75% range, enough that clothes in the closet can start to develop a musty smell and condensation begins to occur on the windows overnight. A dehumidifier is one way to deal with this, but uses a lot of electricity. Just as bothersome, poor crawlspace ventilation results in stagnant, moist air and quickly produces a musty smell which can permeate the house and makes a comfortable environment for spiders and insects. Crawlspace encapsulation is expensive and/or labor intensive, from what I can tell, pretty rare around here. Thus, we looked to this crawlspace fan to resolve some of the stagnant air issues in the crawlspace, which would also hopefully reduce some of the indoor humidity issues in the process more economically than relying purely on a dehumidifier. Install wasn't fun in our 2' crawlspace, but built character (or something). I had to make a plywood frame to get this flush with the crawlspace vent, and also cut out some of the metal sheeting. After initial installation below our master bedroom, we were getting noticeable noise coming through the (uninsulated hardwood) floor. This wasn't really noticeable from the crawlspace, because the noise of rushing air was masking it, but we were getting a tone of ~800 Hz peaks at 35 dBA or so, enough to be annoying without a fan to provide white noise. The next day I went back in, taking some advice from the reviews here to add D-style weather stripping around the perimeter of the metal sheet, and also added rubber washers to all the screws. I also added a timer outlet with a remote so I wouldn't have to crawl back in if we had a power outage or something else that threw off the timing. The weather stripping/rubber washers reduced the sound in the bedroom to 300 Hz peaks at around 30 dBA... a much less annoying tone and perceived at about half as loud, easy to mask with a fan running on low. So, I would recommend that modification if you are noise-sensitive. The fan itself moves a good amount of air and appears to be of very solid construction. I have no doubt about its durability. As to the effectiveness of the additional crawlspace ventilation in resolving our issues, time will tell. I have a humidity datalogger in both the house and the crawlspace, so over time I hope to get some good data about its effectiveness. ## Frequently Bought Together - Durablow 220 CFM Air-Out Stainless Steel Crawl Space Vent Fan, Dual Fans with Dehumidistat & Thermostat, Foundation Vent, Radon Mitigation, for Crawl Space, Basement (Stainless steel, M2D) - 8" x 16" Automatic Foundation Vent for Ventilating Crawl Space Replacement Auto Air Vent, Black, 2 Pack - CrawlSpace-DIY - Vapor Barrier Tape, 4" x 180' PE 12mm Polyethylene Tape, Moisture Barrier Seal and Seam, Insulation Tape for Crawl Space Vapor Barrier, Marine & More --- ## 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.vu/products/16971834-220-cfm-air-out-stainless-steel-crawl-space-vent-fan](https://www.desertcart.vu/products/16971834-220-cfm-air-out-stainless-steel-crawl-space-vent-fan) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-04*
