How often do you change the filter?

I have not changed the filter yet. I am not happy with the bottle. It leaks and siphons for no apparent reason. I have air coming out of the cap when there shouldn't be any coming out. There are other issues others have had and you can see them at Amazon. The seller has ignored my letter that I sent.

That depends on how dirty the air is in the home. Some people change the filter every 6-8 months, other people can go 8-12 months. At our house it depends on things like how dusty the outside air happens to be. When conditions are dry and windy there is more dust in the air. When we have construction going on inside there is more dust. I have changed ours anywhere from 6-9 months depending on the conditions.

I replace mine once a month. You could probably go a bit longer if you don't have hard water and if you clean the humidifier once a week as recommended. I do a thorough clean only once a month and replace the filter at that time since it gets all gunky from both the dust it sucks in and the hard water build-up.

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.

I generally change mine every 3-5 years, but it all depends on the level of pre-filtration, the level of chlorine passing through the membrane, the temperature of the water. I use a .5 or 1 Micron Carbon Block pre-filter and change it every 6 months. TFC Membranes have a very low tolerance for chlorine, so if you are not using a quality Carbon Block pre-filter, the membrane will not last as long.

I would say it depends on the conditions at your home. We live up in the mountains where it is very dusty, so we check it at least once a month. We'll change it based on the amount of dust on the filter paper. We can generally go a couple of months before having to change it out.

I'm not sure what the recommendations are for changing this filter, but when we notice that our water is tasting funny, we change the filter (about every 12 months). There are probably a lot of variables at play, such as the minerals in your water, chemicals, etc.

The unit has a timer that reminds you to change the filter every 6 months. I changed the filter for the first time this month (I've only had my GermGuardian 6 months) but after I did I realized the filter wasn't all that dirty, probably could have easily been wiped off and would have lasted at least another 3 months. We have a large dog but live in Seattle where there's not a TON of dust in the air. We run it 24/7 on medium.

The manufacturer will always lure you to change you filter media regularly/monthly to insure good business. What i do is clean each one 2-3 weeks depending on how dirty the filter is. I clean it under high pressured water. Don't change it unless it no longer capable of filtering. You can see/ base it in your water clarity.

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.

Membrane every 2 years. Filters need to be changed more often--according to the amount of use.

There is a pre-filter that you have to change. There is an indicator to tell you when to change filters. How often depends on what setting you run. I run mine at medium 24/7, high for 1 hour after vacuuming. I change filters about every1 1/2 - 2 months. They're not expensive.

Our shower is used about 2-3 times daily. Our area has extremely hard water so our filters only last about 3-4 months. I change them when my skin starts to dry out (severe eczema,) or it smells heavily of chlorine.

I only needed to replace mine at most, once a month. I would say it really depends on if you leave the filter on when you feed your fish. By turning it off during feeding, I could sometimes go 2-3 months before changing it.

Depending on the amount of use, your filters should last 3-6 months easily. You can greatly extend the life of the filter by using a small hand vacuum or dust blower to clean the filter regularly.

With this particular filter, we change it every three months, I hope this helps :)

I've owned a unit about two years. I replaced the filter after year 1 and just replaced it the second time. The unit seemed to work OK, but the filter does get a little "grungy". I'd say replace at least once a year (I only run the unit during the winter and early Spring months-November to April)
