Ideal Replacement for Nutri-Flow units
Bruce - Henderson/Las Vegas, NV (Thursday, January 31, 2008)
Original filters for the NutriFlow systems cost $75, but NFLI went out of business. I ordered two of the CB3's, and was blown-away by the quality of the water! If you still have any Nutrition For Life HL-250 or HL-300 filtration units, you can now replace the old blue KDF filters for half the original cost of replacement when NFLI was in their heyday, and get the most-amazing water quality that would've made both Bertram and Mitcham green with envy!! THANK YOU!

Stenn from Baltimore is right when he says to not wait for the flow rate to decrease before changing the filter, but you shouldn't use the same filter for 3 years! Carbon block filters remove chlorine taste and odor far longer than they remove lead, chemicals, MTBE, and other nasty contaminants. After several years, the filter may still be removing 95% of the chlorine, but little or none of the other contaminants, most of which you can't taste or smell.
Also, after 6 months, no matter how many gallons have gone through the filter, 'bacteria farming' starts to occur. Before 6 months, the cartridge looks relatively clean, but after 6 months, pink stuff starts to grow on it. So, carbon block filters should be changed every 6 months or sooner, period.
By the way, I've never used this particular filter cartridge, but based on the performance data, it's one of the best carbon blocks on the market.

The filters received are original Omni filters. Delivery was excellent and the filters were the best price found anywhere.
Excellent, and lasts

I've used these for years, and wouldn't consider being without it, after moving up from the 1-micron powdered carbon filter (which was fine too) when I found these carbon-blocks on sale for $27!!..I bought 3 of them. But you can't listen to the '3-6 months' estimate, and on city water don't wait for the flow to slow down as the sign you need to change it, I've been using the same one for almost 3 years, and the taste is just now starting to change, telling it needs to be changed, but flow is still full-strength. So even at $36 it's well worth it, considering how long they last. The difference making coffee with and without carbon filtering is like gourmet and military coffee! :)
