Hi I have only owned my 3 systems for about 6 months. I bought 1 extra filter and I check them monthly and have vacuumed each existing filters I plan on replacing when vacuuming and wet cloth cleaning does not leave filter clean. To tell you I love these systems! Sleeping so much better at night not waking up congested! Worth every penny. And my downstairs does not smell muggy anymore!

It depends on how often you run the unit and how much dust/allergens it's filtering out of the air. If it is always running then generally the filter should be replaced every 6-8 months.

i bought mine in january 2013. my air filter has the digital display. if that is the one you have it will show you an indicator on the display that says "hepa filter reset". mine came up after 6 months of 24/7 use. i replaced my filter at that point. prior to that, i would vacuum the whole unit and the charcoal side of the filter every two weeks. i hope this helped. =)

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.

My HEPA filter is about half used in 14 months. I replaced the fairly inexpensive carbon pre-filter once at 13 months. This product works well, and I don't mind the cost of the filters. The unit has two indicators that tell you when to change each of the filters.Bruce in Texas, retired engineer

you have to replace filter once awhile. Depends on your air quality. I do it every 6 - 8 months. Just buy the matching homeimage filter on Amazon.

It depends on how much stuff you have in the air (I have a lot!) but the recommendation is to replace the black filter every 3 months and the big white one annually.

No, I believe you must replace it. However, my wife has vacuumed it to extend the life a bit. Also, be sure to use the pre-filters sold. They're cheap and extend the life of the more expensive HEPA. Also, they're the ones that remove smell.

Yes, we have that Whirlpool air purifier & we just got a replacement filter a few weeks ago. The Hepa filter that came with it had been in it a year. We change the pre-filter every couple of months. I hope I have been of some help in answering your question.

Replacement filters may be purchased direct from the manufacturer. Honestly we only need to replace them once a year as I clean the machine once a month with a vacuum/ brush and microfiber cloth. We've all had our filters (2-3 in each housed) for 4-5 years. I just bought a new one for another bedroom. Excellent air purifiers.

The hepa filter can be washed and re-used. I have used it for 6 months now without replacing it. I expect it to last another six at least.

The HEPA filter only needs to be changed once a year or so. The bag does almost all of the work.

I change the HEPA every time I go through a box of the vacuum bags (which ends up being about once every 1.5 years). Mileage will vary, depending on amount of pets, vacuuming, etc you do.

According to the booklet, when to replace the HEPA filter depends on hours used, air quality, and location of the unit. In most cases the unit will need to be replaced annually, and it should be changed after the 'change filter' light comes on. For best performance change the carbon pre-filter every 3 months. It warns specifically: "Caution, do not wash and reuse the true HEPA filter or the carbon pre-filter as they will not work effectively." Having said that, I have vacuumed the carbon pre-filter with a vacuum cleaner attachment since it collects a huge amount of dust. I haven't needed to change the HEPA yet.

I vacuum the Carbon pre-filter once a week and never need to change the expensive Hepa-filter.I lay it flat on the carpet dirt side up, use the vacuum hose, no attachment, just as a routine ~~ after 2 or three years I replace the carbon filter.

I bought my IQAir filter sometime around April 2010, and have replaced the HEPA filter once. I bought a spare filter in November, but the replacement light has not gone off yet. I usually run the fan at about Speed 1 or 2, and it is usually on 24/7.

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.

No. A new HEPA filter should be purchased when old one needs to be replaced.

I replace mine every three of four months. Could go longer, but we have a central well in our neighborhood and often get sediment in the lines that has to be flushed out (causing my filter to clog). Generally, activated charcoal filters should last 4-5 months.
