I had purchased a AquaGuard Protect Plus water filter in November 2019. 6 months later, in May 2020, I had called the technician home to check the filer. Upon checking he mentioned the filter inside needs to be changed but the water filter is obsolete. How can the water filter with 1 year warranty be obsolete in 6 months. I again called the company's technician last week who promised to change the filter today, 11/05/2021, on calling him today he said he has no idea when he would receive a filter from the company. THIS COMPANY IS NOT ONLY DISGUSTING BUT ALSO A MONEY MAKING RACKET WHO OBSOLETE THEIR WATER FILTER 6 MONTHS AFTER SALE.
