Some do, some do it to a grester extent than others.

If you run an "on-line" UPS (big $$) then they are very effective zap-catchers, as the PC is always running from the battery supply, and the mains is aways charging the battery. Low impedance of batteries helps to increase the filtering effect.

Most cheaper UPS simply change over to battery, often after the zap has gone thru, typical changeover time is < 20 mSecs, so it depends on the rise time of the transient (spike, or surge) and duration as to the effectiveness.

Generally "zap catcher" type devices are only effective for small spikes, you get exactly what you pay for.
