Does the filter do anything? Do you keep it on?

The filter doesn't do much. I leave it in but it would be fine without it. Otherwise a good litterbox

No it does not use a filter as far as I know. We have never used it with a filter but we are using it for a small indoor fountain.

no, but we had problems with the small holes in the filter part. It would only run 15 min and stop till it was cleaned. that's every 15 min. we had to take the filter out.

More or less. I've noticed it collects some in the filters, but I think what it mostly does is blow it off the floor and walls out into circulation where it's filtered by your primary pump/filter.

No- make sure the filter is in correctly. That caused problems with mine too!

Mine works fine! I probably will buy another one soon. I Think you have to use this filter in order to work properly.

Oh goodness...I wish I could help. My husband got the top off with no problems. I was not watching him when he did it. But it does come off. Wish I could have been more help. It seems to be a very good filter, have had no problems at all.

There are several great short videos on youtube on starting and maintaining this filter.....I have followed their advice and have never had air issues....takes me about 10 minutes to tear down, clean and restart the filter

Filter needs to be changed every 6 months or so - but realistically, I haven't done that yet and it seems to still work well. I run the machine on automatic every morning.

Yes, it does use. The booklet says it's an F2 filter. It's the small, pleated type and it rinses clean very easily so I expect it to last a considerable amount of time. Amazon sellsgeneric F2 filters - 3 for $4.50.

not at all. in fact since the filter stays clean the suction stays strong. the unit is worth every penny.

We leave Ours running all the time , shutting it off and on seems to kill the effect of keeping down the dust and smell better, the filter last long enough and are fairly in expense to replace

I've only had mine for 2months..I'm not sure,but other reviewers have said they have vacuumed or lightly brushed the filter to clean.

I do both. I vacuum the filter but eventually swap it out and its best to swap out you can tell the difference.

No not that I know of. I had it installed by a professional but I didn't see any filter.

The filter creates about 90 percent of the evaporation so it will still work a little, but your best bet is to get a filter and run it intermittently on a timer to preserve your filter life...

Sometimes it does, sometimes not at all. At first it did, and slowly has nearly stopped a month or 2 into use. Put it in a place that is not near you to drive you crazy perhaps? Its worth the filtration! Super worth it!
