great! By wentom on 2/2/2014wentom would recommend this product to a friendSuper great! Between coupon for free shipping, speed of shipping and great price, wish I'd have stocked up! Thought very reasonable when I had to replace all three before though. Yep, wish I'd have stocked up!
Love These By Andrew on 1/28/2014Andrew would recommend this product to a friendI have been using these on my RO unit for about 4 months now. They have really been pulling a lot of rust out of the water and saving my membrane!
High quality reasonable price By James on 1/27/2014James would recommend this product to a friendI've been using the 5 micron filter for about a year. The 1 micron filter is well worth the extra dollar. I get way more out of my membrane now between having to flush out the membrane.
Fits Coralife RO system By Bill on 1/24/2014Bill would recommend this product to a friendI picked up a used Coralife RO system that needed new filters. BRS filters fit and work well with this system.
Great product thats inexpensive! By Nik on 1/22/2014Nik would recommend this product to a friendGreat filter thats easy to change! Buy several at once and change them when you notice a change in color
Cheap N' Easy By Brian on 12/15/2013Brian would recommend this product to a friendI run the 5 Micron filter on my RO/DI drinking system that I use for about 75 gallons a week. In Eastern Minnesota the ground (well) water has an incoming TDS of about 175. The filter usually lasts me about 2-3 months and I swap it out. It does a good job, so I'd recommend ordering a bunch at one time, or just a few that way you have an excuse to buy something else from BRS when you need another filter.
Great product By Susan on 12/2/2013Susan would recommend this product to a friendGreat quality and works as well as the more expensive filters

Great VAlue By Bob on 7/8/2013Bob would recommend this product to a friendThis product is the cheapest i have found it for the best quality. I use only these for my water filtration.
Sediment filter By Adam on 6/14/2013Adam would recommend this product to a friendWho knew there was this much junk in the water we drink?
Love the filter, hate the shipping By Peredhil on 4/9/2013Peredhil would recommend this product to a friendThese filters are great. I stock up on them and change them very regularly since my tap is pretty dirty. My only complaint is that the USPS shipping rates BRS uses must be based on price, not weight. Almost ten bucks to ship ten filters is more than what USPS charges. I understand "and handling" and the box, etc. Just saying their shipping rates are padded.

What's the difference between the 1 and 5 Microns?
Bulk Reef Supply 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.
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.
