Your cart is empty.Made in USA. This fiber screen + carbon filter fits perfectly into 6 inch diameter air ducts with an outer diameter of 5.92 inches. It will prevent small objects and particles from entering your duct system. Carbon filter layer has an estimated MERV 4 rating and will also reduce some odors. Rigid polymer frame is weather resistant. Works well with greenhouses, small shops, and other light duty filtering applications where small objects, particles, and odors are a nuisance. Easily secured at intake with duct tape or hose clamp (not included). Disclaimer: This product is not intended for use with hazardous gases. Max Temperature 180 F. Product works best in duct systems located near the fan/blower and may not allow sufficient airflow if used in conjunction with very low powered fans/blowers. Actual filter MERV rating may vary. A portion of this product is 3D printed and may show layer lines or cosmetic imperfections that will not affect product function.

seal with duct tape, not awful, somewhat reduces light leaks aswell. I like it i just think it needs some innovative designs, like circular clampswith and added drawstring for secure attachment. Will cause backdraft so yup

They work well and they fit right inside the ducting and they weren't expensive and you can replace the filter.#perfect

I bought this to help clean the air in my grow tent. I first looked at the reviews an see photos of the filter hooked right to the tent . I didn’t like this because the filter has no light blocking capabilitys . The air restriction is a bit much but not over board sure it will get worse as the filter I accumulates dust and debris a more reusable feature an b maybe actually hooked to a hose would be better than threw the wall . For light penetration

I purchased these filters for the fresh air intakes for my furnace. My hope is they will decrease the smoke, skunk and other smells from entering our basement. The intakes still have good air flow, so the gas appliances should be fine. The quality seems good, and they are sturdy. I put these filters on the ends of the 6 inch intakes. I could have added screws to keep them in place, but I chose to rape the ends with duck tape to keep them from falling out, and that worked great.

This filter would work great on the end of a duct, recessed into a wall etc. I ended up returning it, because I thought it could be used in-line with ducting on either end. It has a lip on one end, and is more fitted for an "end" application.Still a great filter and product matched the description. This was my mistake, would purchase again when needed

I must admit these things work very well. The build is perfect and was exactly what I was looking for. Perfect for grow tents. They fit the ducts perfectly. I had no issues putting them on and clamping them together.Now the cons…… The price could come down some. These aren’t going to last for years. On that not, last thing is I think they should’ve made these so you can replace the filter instead of eventually throwing it away and buying a new one.Other than that, they’re perfect.

This 4 inch filter worked perfect for me with my 4 inch fan with low Watt LED.I upgraded my lighting and it runs a little hotter so I am now running a 6 inch fan .So I ordered the 6in filter for my intake for my grow tent.It's going to be here tomorrow. When I am done with this run I will take it to my back yard and hose it off and let dry for the next run.
