answer is both yes and a no.

Yes if your power factor is around 0.80
- based on the zone and location pero nowadays all Pf is around 0.93~0.99
- most likely effective in condominium units that have their electricity bill being billed by Admin and not by Meralco (old school)
- might be effective for condominium units that have their electricity being billed directly by Meralco (note might be)
- most likely effective if your zone is within industrial parks like Imus, Batangas, Laguna and et.al.
*** the best way is to check the power factor, if you do not have power quality analizer (which is mahal) pwede din i-try bumili nito sa ace at around 1500 petot then bili ka clamp meter. dapat pagsaksak mo bumaba ung ampere reading. paghinde you probably have a good power factor. ibigay mo na alng sa ibang nangangailangan.

No - most if not all residential complex old or new is already on a separate circuit therefore power quality already improved, like me in cavite "Camella" i bought one to try and to no avail it wont change my ampere reading so it means no effect on my consumption.

Hope this will help.
