ok 1 plant you should be able to take care of.
mites thrive in HOT, DRY environment. so you need to make your environment cool and moist.
if you could take your plant outside and hose down the entire plant including underside of EVERY leaf you can knock the mites off. Repeat for 3 days keeping your plant watered and moist. Get a spray bottle, put 1 inch of liquid soap in the bottom, then 2 inches of vinegar, then fill the rest of the way with water. Spray down the entire plant with this concoction after your 3 day wash off period. Repeat with this spray every 3 days. Good luck this should work.
