Great Filter for the tabletop model.

I have several of these tabletop models and they work well. Low noise and I usually find that 6 months is about the max of time on the filters. I have them in closets and pantry, one in my office. The only negative is that I can't tell if the UV is on, off, or burnt out.

Game changer

These air purifiers are great. They've helped improve the air quality in my bedroom and have made breathing much easier. You can visibly see the difference on the filters at the end of their lifespan - it collects so much gunk! I'm really happy I purchased this and will continue to use it.
