How often do you have to change the filters?

According to the owners manual, both filters need to be replaced after approximately 20 dust bags have been used. The manual also says that the micro-hygiene filter can be changed when it becomes extremely dirty or clogged. I've only had my vacuum a few months and haven't had to replace a bag yet.

I've only had the vac a few months so haven't changed any filters. I love this vacuum! So light and yet so powerful.

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.

Naturally, it depends on how much you use it, but we get at least a month or two out of each filter. We can tell by the taste when it needs to be changed.

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.

Generally, you should change your 1/2", 1" and 2" air filters every 30, 60, or 90 days; the 4", 5" and 6" air filters should be changed every 3 to 6 months, depending on your environment. Thanks, Jessica

When the filter needs changing....yes!!! It's gross. And, the filters don't last long!

It is hard to say. The old filters used to have an indicator which was a no-brainer. I usually change mine every few (3) months or so (when I remember). If you notice the water filters more slowly, I would suggest to change it.

if you keep the filters cleaned on a regular schedule they should last for many years. check your cleaning requirements (very simple and easy to do)

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.

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 have a 2000 sq ft home and don't use the forced air much, maybe 1 hour or so a day. I change mine every 3-4 months. Please see the answer from the filter salesman in reviews.

The instructions state the filter should need to be changed every 6 Months. I bought mine in December 2012 and have not changed the filter yet. The unit has four lights that indicate when the filter needs to be changed. Mine is only on the second light indicator. I run the unit 24/7 on the second of four speeds, and wash the foam pre-filter every month.

I check the filter after the winter heating season and at the end of summer. Depending on use, I change filters once or twice a year.

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.

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.

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

The directions for the platinum model say the filter should be changed every two to four weeks. It also says you can thoroughly rinse the filter and put it back in. I've had no problems with doing that.
