Most sediment filters in aquarium RO systems are inexpensive surface filters that quickly lose their effectiveness when the surface becomes clogged. Purtrex Depth Sediment filters are true graded density filters that capture larger particles at the surface and smaller particles towards the center. This means the Purtrex Depth Sediment Filter will trap particles throughout the entire thickness of the filter.

  • 0.6 or 5 Micron nominal filtration
  • Fits all standard 10" RO units
  • True Graded Density
  • We recommend changing sediment filters when they visually become dirty or a noticeable drop in pressure is noticed.


Many cartridges claim to be depth filters. But to be a true depth filter, a cartridge must be able to retain contaminants throughout the entire cross section of the filter.


A graded density allows larger particles to be trapped near the surface while smaller particles penetrate the larger open areas to be trapped nearer the center of the filter in the smaller openings. Without graded density, a so-called "depth" filter will operate in practice only as a surface filter. The Purtrex filter has the graded density that is required to be a real depth filter.


The Purtrex depth filter is an exceptional value for general applications where long life, high purity and low change-out frequency are required. Produced through GE Osmonics patented melt blown micro fiber technology, Purtrex is a 100% pure polypropylene depth filter with exceptional dirt-holding capacity. Purtrex true-graded density filter matrix (lower density at the surface of the filter with progressively higher density toward the center) captures particles throughout the entire filter depth. This translates to longer life and fewer change-outs than existing string-wound or resin-bonded filters.


Purtrex contains no wetting agents, solvents, anti static agents or binders, and meets the requirements of the FDA for food and beverage contact. The filter incinerates to trace ash for easy disposal.

Product Questions

Does this fit the BRS RO/DI systems? I don't see a BRS-branded sediment filter.
Question by: Adam Carheden on Dec 17, 2021, 3:58 PM
Hey there,

Yes that will fit our RODI systems just fine. All of our systems will accept the standard 10"x2.5" filters.

How often should I replace my sediment filter?
Question by: Walter Davis on Nov 29, 2021, 1:43 AM
The lifespan of a sediment filter depends a lot on the source water and amount of use the system gets but you can expect them to last about 6 months on average. You will know it is time to replace it when it gets dirty or you start to see the pressure on the system drop.

What is the diameter of these filters? Will they fit older OMNI household RO filter systems?
Question by: R D Iverson on Jun 5, 2017, 3:12 PM
These are standard 10"x 2.5" filter cartridges and are designed to work in industry standard 10" RO canister housings.

Have a great day!

What is the difference between the universal carbon cartridge and the CTO cartridge. Can the CTO be used for city water
Question by: carl rode on Feb 17, 2017, 6:02 PM
Hey there! There is a difference in the quality between those two blocks and what they are able to remove from your city's municipal water. Since every municipality is different, you would need to check with your town as to what they use to treat your water. Here are a couple of videos that help you learn why we need carbon blocks, as well as which ones are the best. :-)

What's the difference between the 1 and 5 Microns?
Question by: Christy on Apr 3, 2014, 4:41 PM
Hi Christy,
The microns rating is how small of particles the filter will remove, so a 1 micron filter will remove particles larger then 1 micron. The 1 micron will technically remove a bit more sediment but in most circumstances that isn't a major benefit. The 5 micron is the better choice more often then not because it won't clog as fast.
