How often do the filters have to be replaced and why.

Every year or so, depending on how dusty your home is. A good vacuum cleaner may allow the filter to last a few years or so.

I wait for the red service light and found only the covering needed replaced. about 1 year

depending on what you are using it for. I know smokers have to change it twice a year. Once a year is what I do.

The Filter Queen Defender 4000 HEPA filter should be changed once a year under normal circumstances. The pre-filter that you wrap around the HEPA filter is to be changed every six months. You change the filters to maintain optimum performance and maintain the warranty.

Depending on how dusty, pets. smokers. heavy use every 4 months light use 10-12 months. Change pre-filter at least 2 times a year. I have also sprayed a really dirty filter with Mean Green wait 15 min hosed off let dry in sun.

I am not sure how long I have had mine, but never replaced filters in the past. I wash them after each use. I purchased this one because I changed coffee makers.

It depends on the quality of the water being filtered. If the water is murky, the filters will need to be cleaned more often and may last only one year. If the water is clear, the filters may last up to four years.

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.

We recommend changing the filter every 6 to 8 months. However, the filter life will depend upon the environment in which it is used.

How often to replace is a function of air quality. THey need to be periodically checked for mold or dirt then you will know when to replace.

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.

Most of the filters say replace annually, bit it really depends upon your usage. I usually replace every other year and I haven't had issues with water quality...

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.

They recommend changing the filter every 6 months. I believe the warranty if for the entire unit. There is a filter inside that has to be changed.

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.

Naturally, it depends on what you put into the trash receptacle as to how bad the odor is or how bad it will get. We replace our filters about every 3 months and get along real well the odor control.

Every 3 years. (6 washings)There is also a carbon filter that they recommend replacing.

I believe it is every four months, but they have a "filter club" you can join when you buy and they'll automatically send you any replacement filters as needed on a subscription basis so you won't have to give it a thought. My unit was very recently purchased, that's why I'm unclear on the timing...

Bag and filter replacement will depend on the user's lifestyle. If you have children and/or pets and you vacuum daily, you will probably need to replace your bag every couple weeks. No kids or pets means replacement at two months.

No, we haven't had a problem with these filters and we use a lot of water. We are coming on a year and have not had to replace them yet.
