What do these filters filter out? How can I compare them to the other types?

These are meant to filter extremely small solid particles. Key word: "solid". Pollens, pet dander, micro-dust, etc.. For most hazardous fine vapors (i.e. gases) and potentially-hazardous liquid materials that are sometimes used/applied as "mists" (lacquer paints and insecticides are two of many examples), you would want to use filters made of a different (finer, tighter?) mesh material.

These filters are great and safe for even the smallest of wood and dust particles and are lightweight so are practical for long hours of wearing in the shop. What they cannot filter are solvents and paints. Tried with spray paint the odours and fumes can be smelled. The carbon based typical dual layer cartridges are safe for most solvents, fumes and paints. There are charts online to at 3M to learn more specifics.http://multimedia.3m.com/mws/mediawebserver?mwsId=SSSSSuH8gc7nZxtU5x_9oxmZevUqe17zHvTSevTSeSSSSSS--&fn=ReusableRespBrochure.pdf

I am wearing the mask to clean out a hoarder's residence - dust, mold, mildew and ofther fine airborne ickiness. I believe the mask is good for .01 microns. The manufacturer's website has the details. I have found the masks very effective. Initially it felt claustrophobic to wear, but I got used to it. I definitely notice a huge difference if I am in the environment without the mask. Track your wearing time - the filters are rated for about 40 hours use. I have found this to be fairly accurate.

The wo are from canon. There are three filters that aren't. Hope this was helpful.

I took a look at the filters I bought and couldn't find any kind of holes throughout the filter, not even tiny ones. You might want to post a picture for people to compare. In any case, the filters are supposed to stop tiny particles of dirt. Any holes will defeat the purpose.

Sorry can't really answer this accurately because they sent me the wrong filter.

I have not been able to figure out where the filters go on my unit (don't remember model #.) I haven't used them. Sorry no help on your question.

there is a white and carbon (black) filters on top. Used top change them on my first but not planning to do so on this one as I don't see any difference (and I have an exterior fan to send the grease outside) so no need really for a filter. They go one on top of the other (kind of a half moon shape). You'll have to Google with the model and brand to find them. Hope it was helpful.

Hello. You just need to hold down the filter button until it resets. That should work!

I think the only difference is the color...I do not like the Starkey filters. They are too small and plug up quickly. Just sayin'

I have several in this series and none of them have filters. The only place where I ran into filters is in the bottle filling stations.

It has a single shot and double shot size that are exchangeable. Otherwise I am not sure what you mean by filters.

you are using wrong filter replacements. make sure the filter you use for this system is dedicate for WHER25.

Hi.The one I got had a filter and was on sale for about 18.00. Works great, so I got 3 others for my family. I should be on their payroll. LOL

I have one of each and they are both the same except for the color. Both of them came with a filter.

A quick glance at an Amazon forum from some time ago gives a possibility: Someone posited a guess that it was the extra filter that made the difference. I don't really know for sure.

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 uses a standard Doulton filter. The only thing unique is the housing and connections. I have not cleaned it yet, but I think it will be the same as other Doulton filters.

There are a variety of filters available in the 4.5x20" size. All of them will work. You need to choose for yourself based on your filtering needs. I get mine here:http://123filter.com/catalog/index.php?cPath=64_32
