How many miles do you go between filter changes?

I go on a strict 3000 mile regiment. Royal Purple is by far the best there is and unless you drive very aggressively you could probably do every 5000 or 7500 miles.

Royal purple says At least 12000 I change mine once a year. But it's a summer car so I probably change every 6-10000 @ most

It depends on how soon your scale build up on the filter. I change mine once a month from November to April.

John: I do not know why numbers were not provided. I can confirm that with other premium brand of filter, KN is of low capacity. Do not think of a 1-year or 10k mile interview, half of that or less. I do not feel a efficiency difference.

The documentation says to change the multi-stage filter every 500 gallons, (every 6 months.) The ceramic dome filter at the top is supposed to last 1,000 gallons, (1 year.) I guess it depends on how fast you go through 500 gallons of water filtered.

Manufacturer says 1 yr. I doubt if we have to replace ours at 1 yr, just vacuum the pre filter monthly. That will make a big difference on how long the filter lasts.

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.

Best way is to change filter per summer/winter season....just swipe one in before heating season starts and then when A/C season starts replace with new one. These are great filters and they do collect a lot of dust if you are running A/C all summer long like I do. But if you live in area where you do not use A/C or furnace fan a lot then you might be good to run it for 12 months. Visual inspection of filter will tell you how much dust has collected and then make judgment if the air flow through the filter is restricted a lot or not.

Until the next scheduled oil change. Ususally from 3,000 miles to 5,000 depending on whether you use conventional motor oil (3,000) or synthetic (5,000).

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

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 change the filter twice a year. I could change it more because we have cats, but I don't. It's easy to change.

It all depends on how dusty/dirty of an environment you're working in. A dirtier job like auto body or drywall sanding will provide a shorter life cycle for this filter. Determining whether the filter needs replacing is a subjective thing based on observation and how contaminated the filter has become with the job task.

When I first started using the unit, and there was a good amount of debris in the pool, I needed to clean the filter every 2 days give or take. Once things got cleaned up initially, I could easily leave the unit set to run daily, and only need to clean out the filters every week or two. Your mileage may very depending on the amount of new debris that enters your pool.

I do not remember. I read the directions. It was not long but of course depends on just how dirty your filter is. Follow directions.

They say you are suppose to change your oil every 3000 miles. you prob can go a bit longer with this filter and oil only if it is not hard driveing.

I would not go past recommended intervals. It is a good filter but remember, the filter is the only thing keeping your oil clean. That said, maybe 7,000 miles but that depends on your engine and the amount of dirt that gets sucked into the engine..
