This filter does a great job of keeping my bedroom air clean and removes the allergens that are bothersome to me. With no pets or smokers in our home, one of these filters usually lasts for 10 to 12 months.
From the online reviews I read I had high hopes for this humidifier, but so far, it's just average. I've had it less than a week, but the tank is much smaller than I thought and so needs to be filled at least once a day on the lowest setting, and much more often if it's running on the higher setting. But the loud noise it makes on the highest setting means I won't run it on high often. And while the instructions tell you to not aim the mist at walls, furniture, curtains, you can't adjust the flow so the entire unit may have to be moved or turned. I have a smaller Homedics humidifier that I purchased last year and am using in another room, and I like it much more than this one - you can adjust the flow, the tank holds much more water, and it takes up much less space (and it cost less).
