how frequently do you need to change the carbon filters?

I've had mine about 6 months and so far I've gotten away with periodically soaking the filter in a bowl with a capful of Mr. Clean and water. I use this bucket extensively and haven't had a problem with odor using this method. I plan to go with a 2X's a year filter change.

Yes... A carbon filter to change every month and a foam filter to change every other month. They're not all that expensive

Just because you still have a good flow rate does not translate into you don't have to change the filters. It is important to chane them per mfg recommend times as the charcoal looses its ability to do its job with time and use and mold and fungus can be present (not a good thing) Poney up and change them.

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.

I've owned a unit about two years. I replaced the filter after year 1 and just replaced it the second time. The unit seemed to work OK, but the filter does get a little "grungy". I'd say replace at least once a year (I only run the unit during the winter and early Spring months-November to April)

I believe its a once a day for 5 days treatment. It should say on the box. It does say to keep the filter in without the carbon. I cut a hole in mine and emptied it out.

and usage...if you run it 24/7. I would change every three or four months. Some folks just vacuum the filters. I'm goona try it.)

Do not wash either filter. Replace them. Change the carbon filter every three months. The REPLACEMENT FILTER INDICATOR will illuminate when to replace the HEPA filter. I ordered new filters through Amazon--the Winix 115115 Hepa and 4 Carbon Replacement Filter Combo Pack sold by Green Air.

I would say it depends on the conditions at your home. We live up in the mountains where it is very dusty, so we check it at least once a month. We'll change it based on the amount of dust on the filter paper. We can generally go a couple of months before having to change it out.

I change mine every year. I change my wife's every six months. The activated charcoal no longer functions after a while. If you can afford it, change it is soon as you start smelling the musty A/C odor, which is approximately every 8 to 10,000 miles for us.

A properly cycled tank should NEVER get a FULL water change. Once a week change 25% (50% when necessary)of the water with a gravel vaccuum and add a biological supplement like API Quick Start by pouring it over the filter. Change carbon every 4 weeks, biomax at 6 months, and foam at one year. Rinse Bio and foam (not at the same time) every 6 weeks when changing water.

We easily get 3 months from each filter. If you use A/C 24/7 I'd say every 2 months.

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

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

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.

The manufacturer recommends every six months, you can rinse the carbon filter. The machine has an indicator light that tells you when the filter needs changing. I personally love the winix and it controls smoke and dust very well!

6 months for the carbon filters. One year for RO and DI. Based on my use rates.
