These filter out electrical noise but do not protect against prolonged voltage dips or power outages. Multi-Stage Series Filters utilise surge diverters and LC networks in combination.
It is best to choose a filter with a high surge rating as they offer excellent protection from lightning induced spikes & surges. Both plug-in (plugs into a normal GPO) and hardwired (installed into an electrical switchboard) power filters are available. Many "budget priced" power line filters provide little or no actual filtering, however the Novaris brand of power line filters (such as the plug-in PP10 series, or the hardwired SF series) are fully functional low pass filters designed to effectively filter low and high frequency noise that may be caused by lightning strikes and other electrical disturbances as well as radio frequency interference.
Novaris filters remove noise that may appear between active and neutral, active and earth and neutral and earth. This is called all mode filtering. Novaris power line filters contain high-energy metal oxide varistors in an all mode configuration on both the line and load sides. These two stages plus the filter circuit ensure effective protection for even the most sensitive equipment.
