Are the prefilter and the postfilter exactly the same? It seems like they are both marked prefilter/postfilter.

Yes. Some even replace the pre-filter with the old post filter and put a new filter in the post filter position - but I do not trust that. I want to protect the expensive membrane and we have horrible water anyways.

yes they are in fact the less costly method of operation involves taking the post filter off and puting it in place of the pre filter and putting your new filter in the post position that way you cut operating cost some

Yes they are. Check the instructions for the unit. They need to be replaced every 6 months. In between them is the membrane filter (more expensive ) which should be replaced every year.

This is the pre-filter replacement, not the hepa. This filter (the pre-filter) wraps around the actual hepa filter.

MY BAD ... The pictures show "a filter" being washed, with caption "Rinsable filter and high-quality HEPA filter." I'm not sure but that might mean there are TWO filters, one that is washable and one that is HEPA? I can see why there is confusion on this issue!

I'm pretty sure the pre-filter and hepa filter are together. The pre-filter is at the front and the hepa is at the back.

as long as the thread size is correct there is no problem, filters are interchangeable. :)

Must setup correctly. I always use paper filter. Make sure it's only 1 paper filter.

I don't think they are compatible. You may want to look it up on the web, because the pictures of these two filters don't match.

When I had my filter replaced with the same model filter, I used the multiport valve from my old filter and it worked perfectly. The old valve fit the new filter with no problem.

The box I purchased had two filters in it. The prefilter material is a little taller than the filter in my 50250 but it wraps exactly around like the original. I trimmed it to exact height of filter and have about 1/2 the filter height left. So with the two pack, I am hoping to save the clippings from the two to put together a third. I wished they made them to fit. no cutting required.

I cannot find any markings that would indicate it was manufactured by Pur. I was unable to match the size with local retailers who carry the Pur line of filters. Since it is common practice for companies to have their name brand manufactured by someone else, I was unable to make positive match to anything with the Pur name one it.

I looked at both system filters and they are the same, so no difference I see.

If you go to the manufacturers website and find that model# for the spec page where they will list a part number for the filter. I believe that there is one filter for most of the models (especially in a series like the Architectural Series etc.

It may be, but the one I ordered came with a plastic netting around it, which had a terrible odor that I couldn't get rid of. That was my issue with it. tried twice but both of the filters had that black plastic netting, so I returned them both.

The gage has a brass threaded post that screws into your filter system. You can search your brand on-line and locate the correct part number if you are unsure of the correct part number needed.

Jeff, Does your filtration system have a light (red/yellow/green) that indicates when the filter needs to be changed? Let me know if you do, as I may have your solution! kkt

No my filters were in the correct box and for my model. I have bought filters a couple of times from this site and had no issues.

As far as I know, all the filters are the same except for the water bottle filter. For some reason the part #'s are differeent and make it seem as though they're different filters.
