Honeywell 17000 Permanent Pure HEPA QuietCare
We bought this air purifier back in October 2008 and since then it is totally new air in out home. We bought this basically because I have lot of allergies including dust and dust mites. This particular model I liked because it has permanent HEPA filter so no need to worry about changing filters and their cost. And then it comes from a reputed company Honeywell and its unique design. It pulls air from ground level and then after filtering throws it up in the air. It has three different settings and indicator to clean the filter.
Although it is not that quite on higher levels its pretty good on low level. And for the kind of bedroom we have we usually run it on low. And above all its our personal experience that since the day we got this the air is fresh inside our home. I don't wake up congested in the morning.
We use it all the day and night; while watching TV, working and sleeping. Its very easy to carry and place anywhere like tabletop or on the ground. The cleaning instructions for filter are very easy to follow and you generally need to clean it often only if you have pets at home which we don't. So its the best one for medium size rooms.
Pros: Very good design, Permanent filter, works very effectively in medium size rooms
Cons: Although it says quietcare technology its not that quiet at medium or high settings. Little expensive for personal use. Rating: 5/5
