What is the shelf life of these filters? ... before opening? ... after opening (but keeping in a ziploc)? [home DIYer - a few dusty projects/yr]

3M puts an expiration date on these filters. The date is a few years out. But, there's nothing in this filter that's going to really expire. It just filters out particles. After opening, it should be stored in a clean location. I leave mine to air out for a while before placing into a plastic bag, so moisture isn't trapped inside the filter.

Yes, and I have reused a single filter, at 2 brew ups per day, for several months. They are good until they tear or get a hole in them. Very 'green' if you want to look at it that way.

Do a google search , I have found out they come in carbon block cyl. and 2 1-2 x 10 long , the centers about 1 in You may note the flow rate of each filter. I use my filters in tandem so its rough and then a fine. Go to Lowes or Home depot and you can compare. Note the WHKF-DWHV is 3/4 npt inlets. You may want to put a T in and run them in tandom main feeds the T and two filers at the same time ---======---- parrell NOT series Higher flow rate

Look in the item description and call the manufacturer. They come vacuum sealed, but storage conditions like room temperature and light exposure may affect the shelf life.

I have vacuumed the black odor filter and reused it, however the white hepa filter captures dander and dust and holds everything in. Oreck says the white hepa filter lasts 6 months and the black odor filter is estimated at 3 months. Very hard to find the filters for this unit, had to go to eBay, seller was allvacuumbrands.com.

To the best of my knowledge, they cannot be washed. We've had ours for about 6 mos., and are about to consider changing. If your don't have a real serious dust problem, I'd say 6-7 months would be about the life of this filter.

Ditto Donna BUT I saw on their web site that you can vacuum the filter (usually 12 months from the time you started using it) and that the filter should last a total of about 2 years. Now we know why it was a Gold Box Deal when we bought them!

Hello, Yes, those filters are brand new and still in their retail packaging. Please let me know if you have any other questions. Thanks, Buy It Now Store on Amazon

Go to Monolithic website and read up on these filters. I believe they are good for 6-8 months with the cleaning and shaking then should be replaced.

CharlesouTou are welcome. This has been a great filter. I have had it running continuously (other than cleaning) for more than 7 years with no problems.Mark

My guess is that these are probably somewhat arbitrary claims as the lifespan of the filter is likely dependent on the chlorine content of the water, the hardness of the water etc. I'm no engineer but this probably works by chemical reaction of copper (in filter) and its capturing of chlorine molecules (and others?) somehow...the more chlorine you have, more copper neutralized in the process...? Anyway, I find my filters to last at least six months and seem to be effective for almost a year...

It depends on how you store them, and how much of a perfectionist you are. I vacuum seal them in quart mason jars as soon as I receive them, and store them in a low cool cabinet. They are fine for 6 months.

After opening I keep mine sealed in a ziplock and its lasted me over a year to date. Thanks

I did not see a "use by" date on any of mine. I can say I'm confident that as long as I store it dry it should be practically indefinite. I have sealed my spares in food saver vacuum sealed bags and will use them with confidence any time in the future when opened. A used filter MUST be completely dry before storage so the two I use I do not expect to last any longer than my other filters (i.e. pump or gravity fed). A food saver vacuum sealer is really a small investment for long term storage requirements.

I bought replacements w the vacuum but I haven't had to use them yet. Instead when I go to empty the vacuum, I also clean out the filter (I use gloves and a face mask, I def wouldn't do it without those things).Otherwise, I'd probably switch it out every month or so (I use it to vacuum my studio).

There is no expiration date stated and I see no reason the unopened filter wouldn't have a shelf life of a year or two. Once in use, though, Camco recommends replacement after 3 months. As full-timers, we use our filters a lot and I usually replace mine every 4 to 6 months.

Glad to help. I ordered the 300 count quantity hoping they will work. Decided to chance it! Per filter price lower than other brands.
