Custom Solutions for Every Need
Your Source for All Types of Filter Bags
Discover the perfect filter bag for any application. Custom sizes and nine micron ratings, from a single bag to factory orders, we offer tailored solutions to meet your exact needs across all industries. We use only Food Safe FDA materials
With nine micron ratings to choose from you’ll be able to meet production schedules and ensure quality of the product. If you need strength and fine filtering, using two bags allows fast outflow through the higher micron and then fine particulate removal with a smaller micron. An example would be filtering ground cinnamon from a batch of kombucha by first using a 400 micron bag and then draining it into a 40 micron bag. We will send sample material to you on request for testing your flow through rate, residual sediment, or any other criteria to meet your final product specifications.
Exact Fit
We manufacture kettle and barrel bags using the vessel outer diameter and height - not bag size - so your measurements are critical to our manufacturing. We then add about 4” to the height for overhang and 0.75” or so to the diameter. You can order direct from our site using those dimensions or call us for special sizing. We will make samples at 50% of the cost to ensure the right size, product saturation and outflow rate.
Options
We are the only company in the world that processes orders in 5-7 days and allows the customer to choose from 9 different micron ratings with no minimum order. Our manufacturing process allows you to choose - Any Size - Any Quantity - Any Micron. We make filter bags from 1” to 55” diameter and height up to 72”. Need a liner for an IBC tank? We make those too. You can add a marine grade zipper or drawstring to any bag for easy bottom dumping or submerging. If you don’t need strength we can eliminate the strapping and reduce the cost.
Pre-Filtering
Are your paper filters expensive to replace? We can make a filter bag of any size to pre-filter the particulates and save you hundreds of dollars in primary filter cost replacements. The clogged paper filter is on the right and the pre-filter bag is on the left. This customer now simply removes the fabric filter, gives it a shake and reinstals.
Quality and Reliability
Food safe
All products are manufactured using micron rated FDA (food grade) approved polyester or nylon. Be sure to reference your cleaning and sanitizing chemicals before using them to ensure compatibility.
Warranty
Our filters are guaranteed against manufacturing defects for life. if a seam or stitching ever fails we will replace the bag free. The fabric does not “run”, so if it’s damaged during use it can be easily patched without sacrificing strength or filtering capability.
Durability
Customers have reported using our filters over 500 times! Your cost per use can be calculated at pennies. But, we do make single use bags as well that eliminate FDA requirements for sanitization and eliminate cleaning labor and chemical cost.
Fast Turnaround
We manufacture and ship most orders within 5-7 days. Ship time on orders of 100 pieces or more will need to be estimated. You can expect shipping on 1,000 pieces or less in 10-14 days.
Packaging
Our products can be packed to your specifications whether bundled, bagged, or boxed. All products are labeled regardless of packaging.
No Minimum Order
You can order - any quantity-any micron - any size - and get the same fast service and quality.

Strength Durability
The filters are purposely designed to allow lifting with a pulley or any other device that works in your production room. An electric winch on a rafter or a pulley attached to anything stable makes draining the bags hassle free and eliminates straining to lift the bags. Unless damaged in use the bags can be used in excess of 50 times. Some customers have reported over 500 uses from their bags.
400 and 800 micron bags can lift and hold 400 pounds while all others can lift and hold 200 pounds. If you need fine filtering and strength, double bag the product with a 400 and a 55 or 40 micron. The 400 carries the weight and the finer filter removes the particulates.
The set up in the photo is a 55 gallon kettle with roughly 118 pounds of grain. Wet weight is about 236 pounds but initial water weight lift is over 275.
J. Harms just left a new 5-star review of brewinabag.com:
As always, quality products, made to my specs and arrived quickly. Besides the occasional muslin sack, there are no other bags we use in our brewery.
Brad W., left the following 5 star review for the product The Brew Bag®- Mash Tun Filter for Round Coolers
Been brewing on different setups since 2016. Found the brew bag a few years ago and i just ordered my 3rd one in a new size. BIAB is great and the brewbag makes it even easier. Current setup only cost me about $50 in materials and I’m making beer just as good as thousand dollar setups I’ve run before. Can’t sing their praises enough, I’ll always have one in my brewery.
I've been brewing for about 4 years, 3 1/2 years with an Anvil Foundry with a brew bag. I love the equipment and processes, and I wouldn't brew without by Brew Bag. I've been able to brew great award winning beer with my setup. Thank you Brew Bag! Scott Steenburg - 8/27/23
