18 x 24 Custom Built Laminar Flow Hood (2-3 weeks to ship)

$900.00

If you're tight on space, our custom built-to-order 18"x24" laminar flow hood may be exactly the right size. This flow hood features an 18” x 24” x 6” 99.99 to .3 microns HEPA filter and is powered by a Dayton or comparable centrifugal blower and includes a pre-filter. The unit is constructed from half-inch cabinet-grade birch plywood (no formaldehyde or VOC) cut using lapped miter routers that create self-indexing joints. This improved construction process provides more surface area for adhesion resulting in a superior bond and airtight construction. The cabinet has two coats of low VOC water-based polyurethane finish creating a low maintenance surface. The HEPA filter is protected by an aluminum grill. The grill can be removed for easy replacement of the HEPA filter when the time comes, typically after five years of average use. Overall dimensions are 25"x20"x32", weighing in at 70 pounds. Comes fully assembled, ready to plug and play thanks to the top-mounted switch.

PLEASE NOTE: Due to the size and weight of the cabinet, the shipping cost listed is an estimate to ship from North Carolina to Chicago and is for comparison only. ACTUAL SHIPPING COSTS WILL DEPEND ON PURCHASER’S LOCATION.

Ideal for mycology/mushroom hobbyists, plant cultivators, and small-scale production. This size works well for jar cultivation and working with cultures.

Top quality product. Love the design with metal grate in the front to prevent damage. Came highly recommended and for good reason!


Cougar makes an amazingly high quality product that is both functional and aesthetically appealing. I would absolutely recommend any one of his products to someone who would like to step up their mycological game.


Cougar built me a high quality flow hood that puts out laminar flow (tested with a lighter). At first I was planning on building one myself but the components were fairly expensive and didn't want to risk building it wrong. I put my trust (and money) in Cougar and was not disappointed! Very good customer service and an extremely well made product.


Well crafted and clean finish. Perfect


Shipping was delayed but to be expected with everything going on. Fast responses from customer service and high quality product. Would purchase again.
