Product review (3 stars): ......PLEASE READ
The filter isn't very easy to install but only took a few minutes. A piece of circular metal around the top/bottom would be great so that you don't have to wiggle it on. And it does not have a long service life neither. If I do not use a "bacteriostat" it lasts about 2 weeks @ 8 hours per day. If I do use the solution I get about 4 weeks. It does fit the machine properly. It does the job as intended. But it could also use some ingenuity.
