The Honeywell 50250 N is a mid range air purifier so it is not the cheapest and by no means the most expensive either. You should expect to pay around $160.
Things to Look Out For!
A couple of things to be aware of when air purifier reviews uk buying one of these. Firstly as I said earlier it can be a little on the noisy side when set on a high setting, but if you want to hear it and judge for yourself, I have a video on my website where you can listen. Personally I don't think it is too loud.
There are two models around the Honeywell 50250 and the 50250N The only difference is that the 50250N model has a lifetime hepa filter so it will not need to be replaced. On the Honeywell 50250 model the heap filter will have to be replaced about every 3-6 months and they can be around $100 so the 50250N model is by far better value.
