Frameless storm drain filter

Great product. Holds up really well compared to some of the other brands. Pulled some out that have been installed for a couple of years and they are still intact and working.

Works Great

I use these on several properties and they make clean up and maintenance times reduce by more than half. Will be getting more when I need them.

We have purchased this product for years and have been very happy with them. You only have to change once a year. We change every spring after cleanup.

By Matt


Great Product

Talk about ending all your concerns about what is going down your storm drain. This product does the trick easy to install and one less thing to worry about.

By Russell


Couldnt be easier!

I always wondered what the fabric was doing around the storm drains I see on the freeways & now I know! Great product, super easy to install & the best thing is the city inspector can see we are doing what we can to keep stuff out of the storm drains....after all, the only thing meant to go down a storm drain is rain water! Did I mention they showed up in record time? I love New Pig, I wish all my vendors took care of me as well as they do.

Excellent across the board!

We've been looking into water drain filtration systems, water separators, etc for about a year. Someone in our local government recommended the product & New Pig as supplier. After looking at other products & suppliers we went with New Pig. Product was as advertised, CSR interaction was excellent, delivery was quicker than stated. We will use them again!

By Brock


Good Value

I have searched for quite awhile to find drain inserts and found these to be the best value and quality. Easy to install.

By Amy


Easy installation

We've been using these drain inserts for a few years to help catch sediment in parking lot catch basins. They work great.

By Scott


Drain Insert

Performs great and is easy to install. Best part is it usally ships the same day I place the order so I don't have to keep this item in my inventory.

By Lynnann


Long Lasting Fast delivery

These drain insert are very durable and long lasting. We have about 19 storm drain holes on our grounds and have to replace in stages. We only have to order about once a stage every two years or so. These inserts have saved us numberous times from transmission fluid and oil leaks on the grounds. I would recommend these to anyone concerned with chemicals or anything getting down storm drains. Great Product!

By Steve


Drain Insert

I use these drain inserts at a petroleum truck rack loading facilities spill collection system. They are easy to install and keep solids out of my spill tank and oil water seperator.
