OMNIFilterPentair OM1 Reverse Osmosis Membrane, Replacement Membrane For Use with RO2050 Premium Reverse Osmosis Water Filter System, 15 GPD Flow Rate

worked fine for four months, no longer works what can you do?

I have a ten year old OMNIFilter reverse osmosis filtration system Model RO2000. I've pretty much kept up the maintenance faithfully. The trouble is that our local home improvement center stopped selling the OEM replacement filters. The information that they provided for the aftermarket filters was confusing and I wondered if I was ever getting what I needed. The salespeople were even less helpful (sound familiar?). I finally started buying the best replacements that Amazon had to offer and I was happy with the filters, but they were sold through a third party vendor that charged way too much for postage (no free postage with the 35 dollar order). I was searching on Amazon for the same replacements because I was due to replace these three, and I found this package, but I was skeptical because the model number was slightly different and no information available as to how compatible these would be with the older model. I even checked the OMNIFilter website to see if there was something that would indicate that these were compatible. Nothing there, so I just took a chance with this package and ordered it. I am relieved to say that these aren't only compatible with the older model, they are the exact ones that I needed. Thank you Amazon for carrying this affordable package of filters for my reverse osmosis system!

(1) The supplied faucet pretty much stinks. It gets tight but does not lock completely into the mount, and turning it on and off requires two hands so that it does not detach from the base. Also, it developed a big leak underneath after only a couple of weeks.(2) It gurgles loudly from both the air gap and the drain. I have re-routed the lines several times, and they have always been "downhill". The gurgling has not improved after a couple of weeks of regular use.(3) There is a small drip at the fitting on the end of the membrane cartridge. This came already assembled.(4) The source water is about 55 ppm TDS, and the best this has produced is 10 ppm. We did 6 full fill/drain cycles right after installation and it did not improve beyond that. The Zero Water filter we've been using outputs 0 ppm.

Clearly designed for my reverse osmosis system.I showed it to my plumber and she deleted it from my cart. She tried to say what they sell for twice the price was a better quality & would last longer.To the best of my knowledge this is a OEM product.Needless to say I bought it & am waiting to install.I would recommend buying this product especially through Amazon.

Very high quality system. This is the 2nd one we have had after the first lasted over 10 years. Supplies adequate quantity of mineral free water to our refrigerator door. Also supplies to ice maker. Replaces using city water directly into coffee maker such that it needs frequent cleaning. purchased a less expensive Chinese made system but quality and capacity were too poor so returned it.
