Product review (2 stars): false advertisement
I purchased this filter on June 10th. I received it a week later.  It says it is suppose to last 6 months or 200 gallons whichever comes first. The filter ran out on August 20th. I did not use 200 gallons of water in 2 months. This product was falsely advertised. I am requesting that the length of time stated on the box be corrected.
