When its clean it works great. The built in wire cleaning device doesn't work well on either of my purifiers. I find that about once a month you have to remove the plated, and using a wet towel, wipe down the wire to stop it from crackling. When they are clean and quiet, I love them.
Works great in a 910 Sq. Ft Apartment to take pollen and all sorts of other particulates out of the air. I don't smoke in my apartment so I can't speak to how it works in that regard - but certainly a HUGE difference in the allergies from pollen and dust. Plus - quiet as can be. Without the blue light on the top you would barely know it is on.
I have a very old Ionic purifier that is over 20 years old and it works much better. The new one is always shutting off to be cleaned. It seems I have to clean it every week and I live in a brand new house and have heap filters on my furnace and I'm a clean freak so not a good buy.
This is working after quite some time since the purchase. Follow the directions for care and your success will be terrific. I love it when things do what they are suppose to do!! (By the way---when you clean it, be prepared for alot of gunk it's pulled from your air---it is shocking!)
This is my third Ionic pro that I've purchased. All of them work, they're quiet and good for large rooms. I've noticed that we sneeze and sniffle a lot less and the ionic bars pickup so much filth, its amazing!!. I'm always amazed at how much pollutants there are indoors. Glad I bought these!!!
This has not worked since day one. I cannot return to Overstock. I tried contacting the number in the box it says to contact for damaged returns and have gotten no word back. So I'm just out $120 and have a box that is taking up space. Not happy.
