How often does the prefilter need to be changed?

I've had my purifier a few months now. I've vacuumed the pre filter off several times, and it my opinion, it could be gently washed if necessary and will last a long time. I love this purifier!

The filter that comes with the unit will last a long time. I have been using this for about 6 months and the pre-filter is still good. For maintenance, I vacuum it twice a week and boy this really sucks in a lot of dust specially during the winter time when the heater is always running. So maybe if you clean regularly, it will last a good 6 months.

The system manual recommends changing the pre and post filters every 6 months and the membrane every 1-2 years. I don't use a lot of water and my city water is very clear so I am planning to change all the elements every 5 years. Good luck

Yes! When the filter reaches its limit, the water flow will diminish almost down to a trickle. If that happens for more than 1 day, it's time to change the filter. Depending upon usage, you may need to change the filter once a month.

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.

depends on how often you run it and how dirty your air is. Seems like mine lasted about 9 months being run daily. You just wash the pre filter

The pre-filters seem to last about 4-6 months. We have dogs and that may affect filter life, although they may be on an automatic countdown timer.

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

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.)

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.

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

The filter can be changed either 6 months or a year, but you must remove the front panel and vacuum off any debris about every 2 months, depending on how dirty it gets will determine how often you have to do this.

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.

Really clean the filter or replace it. We need to clean the filter at least every two weeks of use.

Eventually the filter will need to be replaced. As long as you take care of it it last a long time.

It really depends on your water. The higher the number from the wand (ppm) of your water the faster the filter will need to be changed. Our water unfiltered is about 34 and after 5 months we are on the same filter. We use at least two pitchers of water each day, usually more.

The filter should be changed 1 time per month if you have 1-2 animals and more often if you have more than that. If you have any questions, please contact us at tina@pioneerpet.com
