PRODUCT IS WORTH THE MONEY, RUNS WITH 2 DISPOSABLE FILTERS WHICH ARE GOOD FOR MANY WORKING HOURS. UNIT IS QUIET. HAVE ONLY HAD TO USE IT ON LOW-MED AND DOES THE JOB QUITE WELL. HAS BUILT IN TIMER FOR 3 HOUR USE. HIGHLY RECOMMEND IF YOU NEED ONE.
I really love this air filter tower. It's helping with my allergies and it clearly neutralizes the air. I can't say whether it's quieter or not, I've never had another to compare it to. But I can sleep with it on most nights on low without it disturbing my rest. The price was right, and I believe I got more than my money's worth in this purchase. I've never had to clean it yet, but my husband can't believe how easy it will be. I've had it for almost a year, running it on low 4-hrs per night and the filter is still quite clean! I'll follow up with those details when it's time for a change... I am very happy and satisfied with this purchase.
