Filtes: What is the difference between an HMC filter and one that is not HMC?
151670
Hoya Standard filters have one layer of anti-reflectant coating to each surface of the glass to suppress reflection and increase light transmission. HMC (Hoya Multi-Coated) have 3 layers of anti-reflectant coatings on each surface to reduce average reflection down to 3.0% or less. Hoya S-HMC (Super HMC) also have 6 layers of anti-reflectant coatings. Finally, the Super HMC PRO 1 is made of thinner glass (only 1mm thick), also with 6 layers of anti-reflectant coatings bonded to each surface of the glass.

This uses the standard regular basket shaped filters. Sorry if that doesn't help, I'm not sure if it's a numbered thing like other filters.

http://www.filtrete.com/wps/portal/3M/en_US/FiltreteNA/Filtrete/Resources/FAQs/#w5The difference is the level of filtration. There's Standard, Advanced and Maximum. Check the specs and capacities directly at the 3M's site above. Hope this helps!

There are many versions of this filter. 691035 is a standard filter 695666 is a longer version that has a longer life. They will both work just fine for your application.

I couldn't tell any difference from any previous filter, including marking and packaging. If the Moen filters are made in China, then sure. Otherwise, I don't think so.

I bought this for a friend and don't remember a filter. Sorry I cannot be more informative.

I recommend you try the filters from HEPAairdirect. In my opinion they are better quality filters with aluminum not styrofoam housings, made in the US and less expensive than IQair.

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

The black filters are better per many recommendations. If you have any concerns about contaminants get the extra filter for arsenic and such. It slows the filtration but pulls out heavy metals.

I Really don't think there is a difference. I good pop filter is a good pop filter. Either it works as advertised or it doesn't. This one works.

I think the main differences are a better filter and digital controls. But you can do a comparison on their website to make sure.

The "E" is the E core type filter. They have a plastic core rather than metal and a flat plate on top that helps you get the filter on the threads easier. We see no problems with either design and they are interchangeable.

These are not true HEPA filters; they are HEPA-type filters. True HEPA filters are available at http://www.amazon.com/Holmes-HAPF30D-Replacement-HEPA-Filter/dp/B0045LQCIO.

I purchased this filter to use with a Shop Vac Hang Up Mini, which appears to be similar to the 500x. My vac originally came with a foam sleeve, paper filter and mounting ring. I replaced the paper filter with this one (still using the foam sleeve and mounting ring) with no issues. Hope this helps.

From what I gathered, the filters are the same. The PF48F is a "fleet pack" of a dozen PF48s.
