## Overview

The Pentek Bag Filter, model 155384, is a high-performance filtration solution designed for ultrafiltration at 1 micron. Made from durable polypropylene, it is compatible with a wide range of corrosive fluids and can withstand high temperatures, making it ideal for various industrial applications. Its felt media construction ensures a high dirt-holding capacity, providing reliable and efficient filtration.

## Description

The Pentek BP-420-1 Filter Bag provides higher productivity with faster bag "change-outs." The bags are manufactured from felt because it can take on a heavy load of solids, in comparison to similar mesh fabrics. The manufacturing process involves multiple steps: layering together the felt material on a screen for support, then finishing it with a glaze for a secure bond. This is a product that can certainly hold its own as it filters dirt and debris.

Review: Worked great to remove dead mustard algae / pollen / dust (not sure what I was dealing with) from above ground pool that cartridge filter was missing. Zip tied it onto a return hose and ran the pump for a few hours. Pool is finally back to normal :).
Review: I have a 18' Intex swimming pool that had a major attack of algae at the end of last season. I was thinking I was going to have to empty it. I then found these mentioned on a YouTube video, and decided to give it a try. Man, these guys are the real deal. The amount of junk it catches that the filter misses is phenomenal. They can be used by simply throwing them in the wash. I am thinking I will continue to use these throughout this season as it works better than the paper filters, and they are reusable. Inexpensive too. Thank you whoever makes these. If you have a dirty swimming pool, get these.

## Questions & Answers

**Q: Has anybody tried using this with a Venturi style pool vacuum? If so, how well did it work?**
A: I found that these bags work every bit as well as the more expensive ones that our plumbing sub sold us. I will definitely reorder them.

**Q: if you pour water into this how long does it take to drain with just gravity?**
A: Don't know, we pump the water thru it with a pump. I think it would flow right it, with just gravity. A great filter.

**Q: Is this bag "food grade"**
A: Yes it is by definition of “Food Grade”

**Q: Can this be used to filter cold brew coffee?**
A: Not sure. Its ised to filter sediments from water so I'm mot sire why not. But I would think it is for cold water only.
