You can't beat BRS on the price of these filters shipped (trust me, I checked). These are quality products that have helped me maintain great RO/DI water (never above 1 TDS, ever).

We don't keep fish & coral.... we keep water! The fish & coral are just renting space :) Quality water is the life-blood of any system and should be traeted as such. BRS makes this task easily attainable & affordable. Thanks BRS.

Has everything I need to change out my filters every 6 months, and keeps my membrane running clean. I like that it comes with the 2 different sized pores for carbon blocks.

The carbon blocks and Sediment are the highest quality. I strongly recommend this BRS 4 Stage RO Replacement Filter Kit.

I order these, but I haven't had the chance to try them since the original filters on my RO/DI unit that I got from BRS is still producing zero TDS water.

High Quality Filters at A Great Price By Calvin on 10/26/12

Title says it all. These are high quality filters at a great price. The low price of these pre-filters means i can replace them more often thus prolonging the life of the more expensive RO membrane.

Recieved the filters quickly. I purchased this kit to replace filters in my RO/DI system. Replaced filters for 21.00. These filters are high quality and at a fraction of the price compared to other places.

In addition upadte my system to a 5 stage with other BRS products and could not be happier with the results.

If you have a RO/DI system currently or are just looking to replace your filter media. Look no further. BRS has it all and at a great price.

You will not be disappointed!

$21 to changed all my ro filters, pretty good deal. Usually order them when placing a order.

Best Value ANYWHERE By lordofthereef on 2/12/12

These filters are so cheap (in price, not quality) that you would be a fool not to swap them at least every 6 months, as recommended. I like to alternate between this pack and the pack with the DI resin. Both are a great value.

After being out of the hobby almost a year and my old filters sitting for as long, I figured it was best to replace, so BRS hooked me up with the correct filters, and come on, look at these prices!!

So its been 5 1/2 months since I replaced my filters. Before this change the pressure in the meter would read almost 0. As soon as I replaced the filters and reconnected the ROunit, this awesome and cash saving product was up and running and the needle in the meter is registering correctly. Crystal Clear Clean H20

I purchased a 5 stage RO\DI system from a friend. I'd been searching all over the place for replacement filters and couldn't find this set for less than about $40 online and my LFS couldn't get anything below $50. I ordered these filters along with the 75gpd Filmtec membrane and color changing DI resin and I couldn't be happier. I let the unit run for 24 hours to ensure everything was clean and my TDS reading has been at 0 ever since. The tank water looks great and the corals look much better now!

After 8 months of use, the TDS in my unit starte to creep up. I replaced the old filters with the 4 stage filter package and immediately my TDS went back to zero.
