I heard that the filters may dry out and become unusable if left unused for a few days, is this the case?

I've never left mine dry for more then three days and they are fine. Usually we have to refill it everyday so it's only a issue when you leave your house for multiple days.

I haven't yet had to replace the filter. I don't use it that much. My filter is a permanent filter and I just empty it in the trash when I use it.

No. You can use between 1 and 3 filters. The more filters you have, the faster it will filter. 1 filter ~ 14 hours. 2 filters ~ 8 hours. 3 filters ~ 5 hours.

Not sure, but since the filter is ceramic and they give you some sand paper to clean it. I would say you could use it for a very long time without needing to change it.

Yes. Turn off all filters and just use this filter and uv light for two or three days. Amazing results.

A few months ago I had a similar issue, I thoroughly cleaned all the filters let them dry out for a few days and replaced.

Absolutely. I actually had to stop using it due to the horrible smell. This occurred about 6 months after I purchased the unit. I even had washed out the " lifetime filter" , but it has continued shortly after. Was thinking to purchase a new filter and see if that helps. :(

I did not see a "use by" date on any of mine. I can say I'm confident that as long as I store it dry it should be practically indefinite. I have sealed my spares in food saver vacuum sealed bags and will use them with confidence any time in the future when opened. A used filter MUST be completely dry before storage so the two I use I do not expect to last any longer than my other filters (i.e. pump or gravity fed). A food saver vacuum sealer is really a small investment for long term storage requirements.

I use it daily for tap water treatment. the filters have to be primed before use and should not be allowed to dry.

I would say yes BUT you should wash them out and only use them maybe 1 or 2 time more and then just buy filters. Try one out and see.

Yes, but you won't need them right away. The filters are effective for quite a long while are not very expensive. By the way, this is a terrific vacuum cleaner. Powerful and very quiet.

I think from 80 days the filter starts to dry out. Manual recommends another thing but I would tell you refill when the bag is dry.

I have heard that if the filters aren't replaced regularly the water flow is affected. Not sure if this will help your problem but it's something to consider.

I leave mine there everyday only time I empty it is when I clean it or put in a new filter . as long as you use it and keep feeling it, the water doesn't get bad. If you leave it sit to long maybe I would yes and use fresh water.

I've had it for only a month but it's a hard wintertime and air indoors is very dry and full tank is good for no more than 20 hours. I cleaned the filter after 3 weeks but I will do it every 2 to be safe with my hard water.

The filters can initially be vacuumed, but at some point they do need to be replaced. We have been quite satisfied with the performance of our units. When one (we have five units) failed, the unit was replaced without a problem.

Filters last about 10 uses but if you rinse them out really good you can probably get a few more uses out if them. Once they start to clog up with sediment you will know because the coffee concentrate will not flow freely through it.
