I am very satisfied with the purchase of a good product. I bought two units because the yellow dust has been so bad these days. I plan to use it for a few years without buying a filter and then repurchase it when it gets dirty.

It's good because you can use the air purifier and humidifier together. The humidifier is a heating type, so it's a bit noisy and the humidity isn't that strong, but it's good.

Don't expect too much and just buy it with the mindset of buying it.
