I have all 3 Ionic, soft and the HEPA filter. they are by far the most effective air purifiers I ever own. I live in an older house that was built in the 1960s, and dust is a big problem. Finally Solved. 

I used my oven a lot as a barbecue, and smoke is a big trouble. I usually light candles, open windows, and turn on fans to blow off smokes but they don't work well. This air purifier works amazingly well for smoke removing in kitchen.

This thing is great for removing particles from the air! It reduced a visible amount of dust that would usually accumulate on my furniture. It also filters out odours in my room pretty well.

I give it a 5 star. It was delivered next day. I can tell the different already. thanks for the quality.
