Top 10 Foundation VENT Covers
for December 2023

The Crawl Space Recessed Foundation Vent Cover is an attractive, functional, and reasonably priced option that's perfect for installing in your crawl space. The 9" x 17" size ensures it will fit most crawl space openings, and it has a 1" recessed depth, so it won't protrude too far into your space. The Crawl Space Recessed Foundation Vent Cover is easy to install and use; it attaches with screws or adhesive, and it only takes a few minutes to install. The 7" x 15" size makes it an attractive choice, as it's small enough not to take up too much space in your crawl space, but large enough that it captures enough air to ventilate the crawl space effectively. The Crawl Space Recessed Foundation Vent Cover is a good choice if you don't want an open vent in your crawl space, and it's a good alternative if you already have an open crawl space vent, but want to replace and insulate it.

The RazAir Foundation Vent and Damper has a number of advantages over the generic home vents that are sold everywhere, including Home Depot and Lowes. First, the RazAir has a layer of mesh screen between its upper opening and the air that enters it. The mesh screen acts not only as an ember inhibitor, but also keeps insects out. The mesh screen is also made of UV-resistant ABS plastic, so it won't fade when exposed to sunlight. The RazAir is also made in America, and is backed by a lifetime guarantee against defects, so it's extremely reliable. The vent cover is made of the same material as the vent, and it's also paintable, so you'll be able to match it easily to your home's exterior. The RazAir is made of two plastic layers, which make it more durable than the generic home vents, which are made of just one layer of plastic. The RazAir is also much less expensive than the generic home vents, so it's a great choice for anyone on a budget. The RazAir not only makes your home more comfortable, but it also helps keep insects out of your home and reduces moisture in your crawl space, basement, and garage. The RazAir vent and damper comes with a 3-year warranty.

The EZRvent FV100-8H is one of our favorite vent covers. It's well made, comes in several finishes, and is easy to install. Like other vent covers, it gets rid of pesky pests like bees and wasps. But it's also a better option than other vent covers because it has a more professional, finished look. The frame is made from galvanized steel, rather than aluminum or vinyl, so it offers a heavier, more professional look. It also has higher-grade mesh that's thicker and more resistant to tearing and splitting. The frame is recessed, so it won't interfere with doors or windows. It's also more durable, since it can withstand severe weather and pests. The FV100-8H vent cover is 5 1/2 inches high and 14 inches wide, and it covers a range of rough opening sizes from 4-7/8 x 13- to 6 x 14- inches. We also like that it can be installed with screws or nails, so it's easy to install. The EZRvent FV100-8H vent cover costs $30, which is a bit more than vent covers from other brands, but it's the second most expensive vent cover we tested, so it's worth the money.

This crawl space vent cover is easy to install, and it's stylish as well. The vent cover is made of black, heavy-duty plastic, and has a metal support bracket that attaches to the exterior of the crawl space wall. The vent cover has a removable baffle that insulates the vent and makes it quieter. The vent cover is paintable, so it's a great choice for covering up an older vent that no longer functions. The vent cover is also easy to install: Simply remove the baffle, position the vent cover over the opening, and fasten it into place with the four screws provided. The vent cover also mounts with adhesive, so if your crawl space walls are uneven, you can mount it directly to the wall. The vent cover is vented on both sides, so it works well as a return vent as well.

The Vermin Screen Crawl Space Vent from The Vent Shop is a high-quality, well-made, and effective vent cover. It's mounted with screws, so it should last for years, and the included hardware is adequate for installation. The vent has a flat front, which prevents it from blocking airflow, and it also provides better sealing against weather. The design also doesn't interfere with the space underneath. The vent's 95 sq inch net free airflow is twice as much as other vents we tested, and although the vent's total dimensions are the same as other vents, it protrudes 2 inches further into the crawl space, which improves its ability to encapsulate the opening. The Vermin Screen Crawl Space Vent is priced right, and it's easy to install and remove, so it can fit most crawl spaces.

The EZRvent FV100-SS8H is a sturdy, attractive venting solution that's easy to install. Its 316-Marine-grade stainless steel mesh screen is stronger than the 304-grade stainless steel mesh used in most other venting systems. The 316 mesh screen is also much heavier, making it less likely to break or bend. The FV100-SS8H also comes in several colors, including white, black, green, and brown. The Xtreme fierceness edge of the screen is sharp and is designed to keep pests from passing through the vent. The FV100-SS8H comes with a 5 x 14-inch rough opening, but you can modify it to fit openings of 4-7/8 x 13- to 6 x 14- inches. The EZRvent FV100-SS8H has a 120-inch long vent pipe that exhausts air through the top of the vent. It's designed to be installed into the ceiling or floor, but we found that it vents air more efficiently if it's installed horizontally. The vent pipe has eight holes, so you can easily cut it to a custom length. The FV100-SS8H comes with a 10-foot long vent cap that has a 3-inch diameter hole. The vent cap also has a metal ring that you can tighten the cap onto, which keeps the opening in the ceiling or floor from getting clogged with debris. The FV100-SS8H comes with a 40-inch long fan, which is powered by an 8-watt CFL bulb. The fan has a 6-inch diameter, and it blows air out through the top of the vent at a rate of 0.5 cubic feet per minute. The FV100-SS8H comes with a 3-inch diameter air return that vents air back into the room at a rate of 0.5 cubic feet per minute. The FV100-SS8H runs at about $130, which is more expensive than other vented garage systems, but it's well worth the extra cost if you want a vent system that's sturdy, attractive, and won't bend or break.
