Makes a huge difference in air quality. You can tell the breathing difference between rooms if one is used and another is not equipped with these filters.
We have 2 boxer dogs and I run my purifier for about 5-6 hours a day. I have been able to use the same filter for the 7 months before needing a new one. I love the ease of changing these filter out. They are thick and really hold a lot of impurities. I will never use another filter for my air purifier.
I like this item. It does a great job of filtering the air in my 600 sq ft studio. I often light incense. As a test, turned on the air purifier and placed near the source as instructed. Air was fresh in a matter of minutes, and the entire room in no more than 10. Easy to clean. Wipe down some parts, vacuum others. No filters to replace. Manufacturer recommends replacing UV bulb once a year, but aside from the minimal electricity it uses, that is the only expense you should incur. Minimal price, maximal benefit. I highly recommend.
