Very good air purifier

Since I'm allergic to dust, I've had various air purifier at my house in operation.
Mostly these are devices with ionizer which although also work very well, but produce ozone, with the typical odor which can be annoying.
Therefore, I wanted a device with no ozone production and have ordered the Honeywell after a long intensive internet research.
I am very satisfied with the device.

Benefits:
+ Very good cleaning of the air - both dust and odors are very well removed from the air (eg smoke escapes when you open our stove)
+ Solid design of the device - affects functional and robust.
+ Easy to use - filter change is simple, control buttons are self-explanatory

What I did not like so much:
- The unit is really loud and generated a fairly strong draft - in the bedroom, it would bother me even at the lowest level
- The replacement filters are quite expensive

Nevertheless, I forgive 5 stars because the unit's main function - the air clean - enables absolutely perfectly and quickly. After a short time, the indoor air to breathe fresher and more enjoyable.
Would I buy in there again - for dust allergy a real increase in quality of life.

I'm talking about "useful" feedback and please those who want to write me a comment, the rate my review as "unhelpful" - so I can REPLACE the missing information and so improve the review.
