Will plugging in a filter reduce the readings on other outlets on the same circuit, and/or on other circuits?

Yes and this is why the meter is valuable. I have plugged the filter in different locations to test for the best suppression.

Can i use my trifield 100xe instead of this?

No. You need a plug in meter. Like the Greenwave meter or an Oscilloscope thx!

Why do I need this device, if all it does is measure dirty electricity?

This meter is necessary to determine if you have dirty electricity in your home. Per Greenwave, if this meter measures over 50mv (to me 50mv is acceptable) it is considered to be dirty electricity putting out fields that are unhealthy. If you detect dirty electricity, then you purchase the filters from Greenwave. We had excessive dirty E when measured. Some rooms measured over 600mv. Keep in mind the measurements can vary throughout the day (and appliances operating). We measured one outlet in the bedroom that was approx 600mv, when we plugged in the filter and measured the outlet above it, it dropped below 50mv. Since we now have 2 filters in the bedroom and in other rooms, we are now sleeping better than ever - yes the dirty electricity was indeed interfering with our sleep and thus we are feeling better during waking hours. I hope this helps.

Is there an adapter to be able to check 220V lines i.e. furnace, dryer, water heater?

There is a way to do it...but you will have to ignore some electrical safety protocols. A 220 line is simply two 110 lines. Open up the receptacle and use jumpers from one hot line (110) and attach other jumper to ground. Then repeat for the other 110 line. Warning...live electricity...need I say more...careful.
