Query: Filters clog like nobodys business

Got it in early Oct, and about to replace the filter for the third time already.Water flows great for about 2 weeks then it drips slooooooooooowly, taking well over 36 hours to fill the pitcher.People are gonna say its because my water dirty, etc. and blame the victim, but come on, this is ridiculous.When the first filter clogged I called Pur and and they said its not normal. So I thought a original filter was defective and changed to a new one but same scenario repeats.I think these 2-stage filters are defective in design and no way is one going to last the recommended 3 months.Not sure what I'm going to do as its too late to return it now, but I would suggest getting another filter/pitcher combo. Pitcher is great, filter is terrible.
