Is it as good as the original?
There is a significant difference in the assembly quality of this filter compared to the orignals from Honeywell. The black rubberish part is molded unevenly and harder. the cut lines are ragged and uneven...
Which doesn't matter if it works as well. But I no longer trust our foreign outsource producers to make safe products. So I worry, and wonder.
stacking filters not an improvement.
Some reviewers comment on whether or not the filters work. Yes they work, but they do not work as well as the previous replacement filters which did not have to be stacked.
If it is too difficult to make so many different filters for so many different models, Honeywell should make fewer models and concentrate on producing filters that fit and are easy to find.
I've had my Honeywell for 8 years and swear by it, but this filter thing is a problem. Now I have to return them and I hate doing returns which is why I try to get it right the first time.
Air Purifier Filter
This filter works great. If you have allergies, you can notice a difference in the air quality if you use it. I think it's wonderful.
Doesn't fit perfectly in 18150, but works
The filter model I have, 18150, requires two of these with no foam spacers. Two of these were less expesnive than the single larger filter I purchased once previously. However, I'd say that two small ones are about a quarter inch too tall, maybe slightly less. The cover still goes on, but not as far down as it should.
As for filtering, I estimate that it filters the same as the previous. The "permanence" of this filter makes me wonder why I've been replacing the previous style, since I can see no difference in the filter material.
Need to buy multiple!
Beware, you need at least two, and most air cleaners require 3 of these. And when stacked they aren't as effcient as a large single filter. But if you can't find the larger single replacement filter these will do.
