General UPS and power filtering question

Hello!

I live in a heavily populated and industrialized area. This results in the power I receive for my gaming station and peripherals being very dirty. This is noticeable through mostly my Speaker set (noise, pops and crackles e.g. when the neighbour's refrigerator starts compressing) but I'm worried for the longevity of my pc.

I spoke to an electrician who indicated I have two options:

1. Getting a socket strip with surge protection and noise filters
2. Getting a UPS

From what I understand the UPS helps deliver cleaner power as well. I was not particularly looking for a back-up battery since blackouts aren't the problem, but the prices for a socket strip with filter and a UPS are not that far apart.

But what kind of UPS would I need? As far as I can see both solutions use different ways of cleaning the power and I'm finding it hard to compare them. There's many different UPS with different features and I'm not sure which features I need for comparable (or better) cleaning and filtering of power to what the socket strip with filter would offer. In my case cleaning and filtering would be a larger priority than back-up battery capabilities.

System:
- 550w PC
- One 24" led monitor
- 2.1 Speaker set
- Cable modem
- Cable Router

Budget:
- up to 150 euro


In other words: would a line-interactive AVR UPS provide the same protection and filtering benefits as a socket strip with filters?

Thanks in advance!

Hi
If you are trying to remove noise generated from a faulty refrigerator suppression circuit then an RFI filtered socket strip would be the first option to try.
A UPS would only produce clean power when running off the batteries unless it is specifically designed to also act as a filter.

Thanks for your answer! Would an AVR feature on a UPS indicate it's specifically designed to act as filter? For example, on the APC website, the socket strips mention RFI/EMI filters, whereas their UPS units do not seem to contain this. Would the AVR feature on the high-end units mentioned there perform similarly to these filter?

Yes some AVR UPS do have RFI filtering but only if they explicitly state that in their specifications and most often the RFI filtering only works when the unit is running off the battery because the UPS itself can be a source of RFI.
If you are concerned about RFI then get a socket strip,if you are concerned about voltage fluctuations then get an AVR and if you want power when the electricity supply fails then get a UPS.
