This is my honest review, I really do like the air purifier. As a matter of fact, I purchased a 2nd one for my son-in-law who has allergies. I also purchased a nother filter for my air purifier. I had read in the description about the filters that they will last 6 months or you get a new filter for free. Well, my filter lasted about 3 to 4 months. So I contacted the company & told them about it & asked for my free filter. Yeah, there was all kinds of excuses why they couldn't send me out my free air filter. So now I will have to purchase another air filter. That is my only complaint so far. Otherwise I do really like it.
