how often do you need to change filters?

It really doesn't have a filter, it's a cotton wick to wick the water to the atomizer screen. The instructions make no mention at all of any kind of filter. It possibly does act as one a bit, but the instructions also make it clear you should use distilled water so that the atomizer screen itself doesn't get clogged, i.e. water impurities will travel up the cotton wick. Not sure where you'd get replacements either way.

Honestly, this thing didn't last long enough to worry about changing the filter. It cracked and busted within a few days.

I didn't use mine long enough to need a filter change. But from experience with other humidifiers, you should change the filter when it becomes discolored. The filter is you wick for moving the water to the top. When you notice a change in the amount of steam, the wick is no longer effective.

I did not have to change filters because this product broke after 10...count them 10 hours of use. Do not buy this product.

Depending on hours run and amount of particulates in the air, every 2-6 months. If you get one of these: G99 Air Filter Gage and install it properly (quite easy) it will tell you when to change filters. Pays for itself in the long run.

I just estimate how many times I fill a day, which means for me, about every 6 months. This is based on the manufacturers recommendation for length of filter use.

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.

The best practice is to change it every 8 to 12 months. Even flowing strongly after that time filter could have lost part of its filtering properties.

I change the filter for our pooch about once per month. Depends on how hard the water is where you live. If you use filtered water it should last much longer.

I change all the filters once per year with the exception of the membrane. That one is good for three years.

The heating & air conditioning system I have recommends every 6 months. I know if you don't change them when the filter is dirty it will shorten the life of some components, particularly the fan motor due to the additional load caused by restricted air flow through the filter.

It really depends on your water. The higher the number from the wand (ppm) of your water the faster the filter will need to be changed. Our water unfiltered is about 34 and after 5 months we are on the same filter. We use at least two pitchers of water each day, usually more.

Printed on the edge of the filter: "Change every 6 to 12 months - more often if the filter appears dirty." My HVAC person recommended every 6 months.

I change the black filters about every 3 months. The hepa filter about every year. But the hepa filter needs to be cleaned. I clean mine 3 times a year. use a soft brush and then by water. Do not use any soap, just water

We change ours yearly (recommended for a household of 4), but really depends on water usage. I have been told, if your water pressure drops drastically, that is another sign that you need to change filters.

The only other reason to change more frequently is if microbial contamination is a concern, I put a UV light treatment unit following my RO system to help fix any problems encountered here. Now I have a UV light to change once per year and another filter to change once every 6 months in addition to RO filters and membrane service intervals.

First of all the cleaner the filter, the faster it filters. When it is new, it will filter the full amount in about 6 hours. After the filter gets some use, it will take a bit longer. I take mine out and wash them every 3-4 months and change them once a year.

When I bought the system it said on the box that for a family of 4 the filter should last about 1 year or something like that - now depending also of usage. I would at least change it once a year even twice in fact as I got more filters with my last order.

Depends on how much water goes through them. I fill the reservoir 2-3 times a day (about a liter fits in the reservoir). I change my filter about 2-3 times a year.

Depends on how often you run the machine...I run mine about 12 hours per day and I change the filters about every 18 months.
