The main reason why I bought this product for my family was to clean the air in our home from the odors that seemed really hard to eliminate with traditional cleaning. Right away we noticed that the dog smell in the air was practically eliminated when we leave the unit running. When we return from being away from home for a few days or turn the unit off, we really notice a difference in the quality of the air. It has also really helped with our allergies. I will say we leave it running all the time and have recently done renovations to our home, so that may be the reason we need a new filter already.

This really works to clean the air of smells and allergens. I honestly was surprised by how clean the air smelled when we first bought the unit. It really does the job we wanted it to. Though I wouldn't say it's whisper quiet at the lowest level, we leave it running all the time and we really don't notice the noise. Though it's not inexpensive, compared with similar high-end products on the market it's priced reasonably. I can't imagine something more expensive being more efficient. We've found this product to be worth the money that was paid for it, and it's much better than having bought something at even half the price that didn't work as well.

The filter needs replacing after a year of use, but as I mentioned, we leave it running all the time and have done renovations in our home that probably contributed to the lack of longevity in the life of the filter.

If you're looking for an air-purifier that will rid your home of smells and allergens, you won't be disappointed by this purifier.
