I purchased this cartridge to replace the original cartridge in my Omni CBF3 undersink filter unit. The new filter assembly is 0.0125" taller than the original assembly. The new filter uses thicker gaskets on the top and bottom surfaces. The taller filter will not allow the top and bottom halves of the canister to screw together sufficiently to compress the filter unit sealing o-ring.

As a result the canister now leaks.

Several emails to Omnifilter prompted a half-hearted response from a lady named Linda. The conversation follows:

Me: Explanation of the problem...

Linda: Please remove the gasket on the cartridge and re-insert the cartridge. This should stop the leaking.

Me: If I remove the gaskets there will be no sealing surface to force the water through the filter. The water will bypass the filter.

Linda: The water will still go through the filter without the gasket.

Me: Are you indicating that, without the use of the gaskets, the filter will make a WATERTIGHT seal with the upper and lower halves of the filter housing?

Linda: Yes.

The less-than-enthusiastic response led me to keep the old, thinner washers in the unit. So far, no leaks.

P.S. If my research is correct, this filter removes particles larger than 0.5 micron, whereas Brita filter pitchers only remove particles larger than 30 micron...60 times larger. My old socks filter water better than a Brita pitcher.

The Omni CB3 is an under sink filter replacement cartridge. I use it as the second stage of a dual filter system, a generic carbon filter is used in stage one. My experience over several years of use with this setup has been outstanding. I rely on surface water coarse filtered through a swimming pool sand filter as my only source of water. From a cistern it is pumped to a whole house system. A bar tap faucet at the kitchen sink is connected to the under sink filters and provides all my drinking water. The CB3 provides safe drinking water for 4 to 5 months. The flow rate drops as the filter reaches capacity. The CB3 takes out volatile chemicals, lead, chlorine, sediment, and its 0.5 micron rating traps cysts from animal waste. My wife tells me daily that we have the best drinking water she has ever tasted. I agree. I highly recommend this filter for safe and tasty water.

An Omnifilter CB3 Series A weighs 635 gms. These weigh 520 grams. Looks very similar to a CB3 but how do you explain the 115 gram difference? Great price but exactly what did I just buy?
