It’s now May 2011 and PUR still has the same problem. I’m on a well with about 40-50psi and didn’t make it through one filter before it sprung a leak out the small, clear window. I bought a set of 3 filters thinking it was only a stopped up filter. WRONG!! it leaked with the new filter. I guess I’ll drink my well water. The water taste is great but I hope the extra limb I’m gonna grow will come in handy:)

Looks like you have bad luck with filters… maybe you should just drink the tap water and hope you don’t grow extra limbs

The new PUR filters as of Oct 2010 are redesigned, and do not develop stress cracks due to new material resins. I agree the old ones lasted 12 months at best.

Well we’ve been using the dupont filters for about 2 years now. They last longer than the other brands. And make our nasty tasting city water actually enjoyable. They’re cheaper too. Our daughter gave us her pur when ours sprung a leak (about every 6 mos) she said it only needed a filter $17!!! Right next to it dupont faucet mount filter with 100 gal filter $18. It may only be one stage of dupont magic – but it works.

Yeah! Pur is bad, they fall apart, so does britta I did finally buy DUPONT WF-FM100, the mechanism seems better with the water pressure inside the filter instead of outside as said above, but also i cut one of their FM100 filters open and also found not 2, not 3, not 4 but only ONE carbon filter as well (again as said above). BUT the good news is that it may be alot easier to CLEAN and resuse the filter than we think: What if we “backwash” the long used filter with Hydrogen peroxide (harmless in low quantities to humans), then clean again forward washing with clean water to remove any residual HPeroxide? In other words you can unscrew the housing as if you are replacing the filter, then by trial and error you will realize that the intake is the outer nozzle on the filter, so just force water (or HPeroxide) in thru the center nozzle to backwash the contaminates (mostly minerals i would think) out the other nozzle, then reassemble and run for 5 minutes to make sure its clean enough again. SO NOW you have a working system again that is still uncut, undamaged, and should output water at a higher rate than it was (more like it was like new). I may try this next time the filter gets too clogged up to get a descent flow (its pretty slow even when new but liveable for drinking water which is all we want).
DOES ANYONE KNOW OF ANY FAUCET MOUNTED CHEAP SYSTEMS THAT WORK RIGHT AND HAVE THE CHEAP REPLACEMENT FILTERS TOO?

I bought the Aquasana 4000 filter system. I found this type of drinking water filter far superior to any others. Check out the comparrison chart on the website http://www.bestfaucetfilter.com.I have owned mine now for over 3 years and all i do is replace the filters. Why buy a cheap tap filter that doesn’t remove contaminants?

The other brands of filters are typically at Menards, Home Depot, True Value, Ace Hardware (all hardware/building materials) stores, the Brita brand has been merchandised into the big box chain stores like Walmart more successfully so you see their brand much more often.

I am curious, where do you find filtration systems like this? The only ones I have seen around are the Brita brands.

Scott –

I agree that water pressure surges when the filter is rotate are likely to blame for why the plastic PUR filters fail over time. The inside of the filter was just spider webbed like the outside.

With regard to water pressure, I’m a student and have moved to 3 different houses in the last 3 years, so I’m not sure what the pressure is, the plastic PUR filter failed on the 2nd floor of an apartment complex. The replacement metal one started bleeding water out all of the seams in the next house I lived in. Finally, I’ve had 2 Omnifilters die and Menards appears to be closing them out so I won’t have a chance to try another. The first one is pictured in the post, the second one had the filter shatter when pressure was applied to it.

I’d love to sweat in a filter under sink and just plumb it up to the faucet but I can’t in rental properties. You’re absolutely right that it’s the only way to assure good performance out of these filters.

What is your water pressure? I’d be interested in seeing the inside of your cracked filter housing. Did you have a practice of swiveling the filter on and off with the faucet at maximum flow? That would probably add a lot of stress to the filter assembly.

My PUR aerator self destructed after 1 year of service. There was a threaded PVC collar that fit around the aerator assembly (for the unfiltered water). It cracked in half, releasing a bonus stream of water. Attaching the original chrome threaded aerator (an item in every American kitchen and hardware store) fixed the problem immediately. Couldn’t they save money by not including their low-quality aerator? Add one more instruction that says, “screw your aerator back in place right here.”

The filter assembly is a great design. I wouldn’t have bought it if I didn’t see its value. However, if I worked at P&G, I’d identify these deficiencies:
1) You don’t want the filter to be attached to the hot water line (bad defensive design).
2) The swivel valve can subject the filter cartridge/housing to quick pressure changes.
3) The filter’s positioning on top of the kitchen faucet takes up valuable kitchen real estate. The filter housing is something of a 50-70 PSI pressure vessel that makes a great target for dishes and pots and pans to clank into.
4) The faucet assembly is sold under a razor blade model. It needs to last a handful of filter lives before failure to ensure profitability. Regular kitchen fixtures usually cost $100 and up and are installed by a plumber or a homeowner who knows some plumbing. It’s an inevitability that soccer moms will be upset when they see that their PUR filters cannot hold up the way their designer Kohler fixtures do.

Simple solution:
1) Sweat a cold water line up from under the sink to about eye level against the backsplash area. Include a ball valve for control and a union for easy access.
2) Buy a filter housing with no moving parts. Find good filters.
3) Enjoy.
