The filters appear fine. I have not actually used them. The annoying thing about this purchase is the amount of emails and online advertisements I have received from this company since I bought these filters. I feel that I am constantly bombarded. Give it a rest. I have already bought the filters.
The filters and the buying process was five stars. The incessant badgering after the sale ruined the whole experience. I don't need to get an e-mail every day reminding me to buy more filters when I just bought a six-month supply.
