I returned my alen A350 after about a week of use because of the high noise level. I recall reading that filter change varies according to use and conditions. Every 6 to 12 months is the norm.

I have owned and Alen 350 for about 5 years, and changed the filter about every 6 months. The indicator light does advance to red at about that time. I now own a new one, and the light seems to be progressing at about the same speed. I run the unit 24.7.

The instructions state the filter should need to be changed every 6 Months. I bought mine in December 2012 and have not changed the filter yet. The unit has four lights that indicate when the filter needs to be changed. Mine is only on the second light indicator. I run the unit 24/7 on the second of four speeds, and wash the foam pre-filter every month.

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.

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.

Depends on frequency of use - I use mine daily but filter water 4-5 times a day. Monitor pH every 3-4 months to see if filter is still achieving your desired pH . If not, see if holding longer time produces more alkalinity. If not , time to change the filter. I typically change out my filter every 10-12onths. But this may vary according to the pH of your water.

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.

Depending on hours run and amount of particulates in the air, every 2-6 months. If you get one of these: G99 Air Filter Gage and install it properly (quite easy) it will tell you when to change filters. Pays for itself in the long run.

I change the black filters about every 3 months. The hepa filter about every year. But the hepa filter needs to be cleaned. I clean mine 3 times a year. use a soft brush and then by water. Do not use any soap, just water

It is hard to say. The old filters used to have an indicator which was a no-brainer. I usually change mine every few (3) months or so (when I remember). If you notice the water filters more slowly, I would suggest to change it.

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'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)

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

It depends on how much of the filter is covered. I change the filter before each time I use it.

Prefilter: Directions say every 90 days. I run my filter 24/7 and need to change the pre-filter every 60 days. HEPA filter is supposed to last 1 year. I change mine more often due to severe allergies and chemical/fragrance sensitivities; mostly due to scent.

I find that changing that filter every 12 to 18 mos. is plenty to keep the water clean and fresh. As others have said, the company says annually, but they are making money more often that way. The filter I bought here is exactly the same except it has a lower price. What is not to love about that? (put masking tape on your filter and put the date your new one should be installed right on the filter casing.)

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.
