Title: filter for vaiable speed pump
Review: This filter was recommended by Hayward and x-10 as a fix for the electronic noise the Hayward ecostar pool pump produces that interferes with x-10 wireless modules. Even though the filter is advertised as 220v, it only filters one leg (110v). If you need to filter both 220v legs you have to buy two filters with no guarantee that it would work. Never-the-less, it would only provide sporatic filtering capabilities when the pump ran at low speeds and none at higher speeds. Essentaily useless for this application.
