## Features

- INCREASE WATER CLARITY & QUALITY: Felt filter bags are most commonly used to help collect and trap free floating debris, excess food and detritus, which in turn improves the water clarity and quality of your aquarium and the quality of life of your aquatic population, making them happier and healthier and contributing to longer lives.
- REMOVES EVEN THE SMALLEST OF PARTICLES: A micron is a unit of measure in the metric system equal to 1 millionth of a meter in length. The human eye cannot see anything smaller than 40 microns in size. Since this felt filter is 1 micron rated, it will capture particles and contaminants that are slightly smaller in size than bacteria. This is the smallest micron rating on felt filter bags.
- EASY TO CLEAN: You can wash your felt filter bag in a laundry tub using hot water and a little bleach. Simply wring it out, let it dry and reuse. These felt filter bags have the ability to be reused over and over again. Don’t feel like washing the felt filter sock? No problem. Simply throw it away after it has been clogged and purchase new ones. It is recommended to purchase multiples if you do not intend to reuse them.
- DURABLE MATERIALS: Our food grade felt is made out of polyester which is known to be a strong and flexible fabric that dries quickly. This felt filter bag has also been designed with a carbon steel support ring and hanging strap for extra strength, security and support. Using this type of high quality mechanical filtration device helps to increase the overall life of your filter.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good quality, great price
  

*by M***S on Reviewed in the United States on January 17, 2019*

This is actually an amazing value.  It is quite abut larger then some of the other filter bag I’ve looked at.  I am using these to remove impurities from home made tinctures, wines and as a rain water catchment filter.  I have tested how well it worked by checking the product after filtering it with a microscope and am glad to report that it works just a good as it should.  There is darn near nothing on the slide larger then a micron.

    Bigger is usually better but may not work for my needs
  

*by K***. on Reviewed in the United States on June 22, 2018*

i havent used this yet. it arrived on time. It seems way bigger than described but i will go back and check that. Bigger is usually better but may not work for my needs. I will update review after I used to filter my homemade wine. I am hoping to push it up to 5 stars (If it gets all the yeast out).
