I just saw a crazy review here. They said the Terminox Filter at BudgetWater.com did not work well, but everything they say is incorrect. Budget Water CLEARLY states on their website the the pH of water needs to be ABOVE 7.5. This person says Budget Water said it was too high at 6.8. That is ridiculous. Their website clearly states the opposite. 6.8 would be TOO LOW for ANY good iron filter. pH of 6.8 is NOT acceptable for good iron filters. Period. This malicious post must either be a competitor, a TROLL, or both. Or they are maybe the most uniformed and unintelligent person on the planet. Not to mention it is just plain sleazy to lie about any company this way. I have installed more than 15 Terminox filters for my customers. All are perfectly happy and refer business to me constantly. Of course I follow the instructions. The idea that no plumber would install it is just plain incorrect. A blatant lie. They are so easy to install that many of people who buy them install them themselves. Many are housewives. Why would any plumber or handyman refuse the money for such a simple install? That’s just silly. Not odd at all that someone would post it on this RUSSIAN site. Just look at the WHOIS directory. This site is originated in Russia!
