The manual has all the info, http://files.sharpusa.com/Downloads/ForHome/HomeEnvironment/AirPurifier/Manuals/pur_man_KC850U.pdf True HEPA filter Up to 5 years after opening Filter life can be greatly reduced depending on the room environment. Cigarette smoke, pet dander, and other airborne particles can reduce filter life. Check filters regularly and replace as necessary. Washable Deodorizing filter Up to 5 years after opening The filter can be repeatedly used after washing, or it can be replaced. Humidifying filter Up to 2 years after opening Filter life can be greatly reduced depending on the room environment. Even if 2 years have not passed, replace the Humidifying filter if you notice the following: * Mineral deposits (white, black, or red masses) which are not removed after cleaning or the Humidifying filter is still dirty. * Filter is severely damaged or warped.

When the filter needs to be changed, the water flow slows down. It all depends on how many contaminants are in your water. My water is pretty clean, so I only have to replace the filter every 6 months.

I do as they recommend, scrub the dome once a month and replace the 5 layer filter every 6-8 months. The dome gets minerals deposits on it so it is good to clean it. Only takes 5 minutes.

I have used this filter the same way for about a year now. Single person use, drink a gallon daily, use it for cooking. I replace every 5 months.

The reverse osmosis filter is supposed to last 5 years. The prefilters (in the 3 vertical cylinders) need to be replaced every 6 months.

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)

This filter is intended to be changed every 12 to 24 months. It is recommended that the average household change it every 12 months for optimal performance and 18 months for optimal value.

Hi Maria, The filters need to be changed once a year for a home or small business usage. For a medium sized business (10 or more employees), you'd typically change the filters twice a year. The cost for both filters is $49.95. They are being put on Amazon in the next several days. They were waiting for new product photos. You will be able to buy them when it's time to change the filters for sure. Thank you.

First of all the cleaner the filter, the faster it filters. When it is new, it will filter the full amount in about 6 hours. After the filter gets some use, it will take a bit longer. I take mine out and wash them every 3-4 months and change them once a year.

I change mine every 6 months but it depends on the hardness of your water. The filter can not be serviced. I usually recycle it with my plastics.

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.

I change my filter every year. I used my for about 35 to 40 days a year camping

The heating & air conditioning system I have recommends every 6 months. I know if you don't change them when the filter is dirty it will shorten the life of some components, particularly the fan motor due to the additional load caused by restricted air flow through the filter.

The company that installed my new system said that this filter would last one year. But when they came out to do an inspection after one year, the guy said that I should have changed the filter earlier. I now change the filter every six months. So far, that seems to be about the right amount of time.

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.

We change ours every 3 months (90 days) - We have a thing set up with Amazon to send us a filter quarterly, we have an extra on hand so after I use the one I have a new one waiting. Ours has a dial on top to tell me when to change (in case I forget)

I changed mine after two years..it kinda depends how it looks after two years. The sponge filter that surrounds the filter is delicate. It holds up to gentle washing for a while.
