how often do I change filters?

This type of filter is to be changed when breathing resistance is felt. It is for particulates and will work for fumes (welding) but not for vapors (acetone, MEK, solvents).

Every 3 days, but it depends on the job you're doing. I break concrete daily and have to replace them every three days.

I purchased two of these for my brother and I to use while we removed old fiberglass insulation in an attic and replaced it. We used them daily for 4 days and did not need to change the filter during that time. They performed wonderfully and were more comfortable to wear than expected. I would purchase again.

It all depends on what you are using it for. I use mine only for dust particles and don't need to change it often. It is a personal choice as to hours of usage and type of usage as I said. I do not use mine for painting or fumes,as I believe, it is not meant for that purpose.

It depends on how soon your scale build up on the filter. I change mine once a month from November to April.

Depends on frequency of use - I use mine daily but filter water 4-5 times a day. Monitor pH every 3-4 months to see if filter is still achieving your desired pH . If not, see if holding longer time produces more alkalinity. If not , time to change the filter. I typically change out my filter every 10-12onths. But this may vary according to the pH of your water.

It depends on how much of the filter is covered. I change the filter before each time I use it.

I change the membrane once a year and the filters every six months. Works well for me.

It depends, I have 4 cats, so with all of that fur and dander, I change my filter every7 weeks or so. If you vacuum frequently that helps the filter last longer. When the filter starts moving from white to gray, it's time to dump it.

I find that changing that filter every 12 to 18 mos. is plenty to keep the water clean and fresh. As others have said, the company says annually, but they are making money more often that way. The filter I bought here is exactly the same except it has a lower price. What is not to love about that? (put masking tape on your filter and put the date your new one should be installed right on the filter casing.)

Manual (Page 18) says every 3 weeks, but it depends on how hard your water is. If you have soft water then it's much less frequently (I use distilled water so I don't even need a filter).

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.

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

I change it every 6-8 weeks and I buy them from Amazon. Since the water sits out for approximately a week (unlike our human water), it's a good idea to use the filters.

Around 3 months ... depending on the level of dirt. When I first got Neato, I had to change filters about every week or so, but now that it's keeping carpets much cleaner for me, it's about every 3 months.

I change the water every week and rinse the filter. So once a month I change the filter unless it looks dirty before.

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.

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

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.

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.
