Power Filters Necessary?

[NaOH]

I feel like home theater equipment should only really need a surge protector but should be fine other than that. I would think that most equipment has some minimal power filtering built in. What do you guys think?

It probably depends on how clean/dirty your power is.

I got a UPS after becoming worried about the quality of the power at my apartment

Everything seems to be working fine so I guess I won't blow my money on one.

That's awesome... Check out this projector install in the airport bar at Dutch Harbor, Ak. I took these about 7-8 years ago.

I saw your thread title and wondered what an aquarium question was doing in the Audio/Video forum 😀

To respond to the intended question (and admittedly repeating what others already have said), it depends on how clean and dependable your mains supply is.

I will also repeat the warning to ensure that any UPS you obtain for A/V equipment is rated for Home Theater use; most computer-market UPSs have a "stepped" output rather than a clean sine-wave output. This funky voltage wave is no problem for a PC's switching-regulator power supply, but it has tons of high-frequency harmonics in it that a simple transformer/rectifier/pi-filter supply like that in a lot of A/V equipment is not designed to handle.

Where I live I have horrible dirty AC power. I basically could not safely use any of my HT equipment or even my LCD HDTVS without using some kind of power filtering. I can see a HUGE difference between using regular unfiltered AC power and a high quality filtered power strip or power filtering component. If you don't have a problem with noisy transformers or people nearby using electric power tools that cause constant AC line interference, then you likely don't need it.
