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.

I don't know. I would think the picture of the box would be the most accurate and the other number may be an error in the typing. Might look at 3M Filtrete web page and see if there are two different products. Sorry I cannot be of help. My order also says 3US-PFO1. Not sure what I received but it works in my equipment.cts.

Don't know, I got rid of both filters, they sucked, both leaked from day one. Piss poor molding on the too half. Don't buy it

Yes, this is a 1900, MRV12 filter with a pressure drop of .21 and captures 90% of all particles. I called Filtrete and asked. Too bad Amazon couldn't figure that out! Also, the "Healthy Living" line is made only for Amazon, that's why you won't see it on Filtrete's website. It's just their normal filters with seemingly less information and different packaging.

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.

Purenex FT-1. When I bought this I got the Matrikx Pb1 filter cartridge and it fit perfectly. This one has the same number but is smaller in diameter and is not working.

One has a cotton filtration underneath the other does not. Buy the cheaper of the two.

Yes, it is the same filter. I have both types of boxes and use them in each

The filter basket (the plastic basket that holds either a disposable paper filter or a permanent filter) is included, as is a filter disk. Paper filters are easy to find, and I think I recall that 1 was included. The permanent filters work well, and may be worth the few extra $.

They also sell those filters right here on Amazon. Just look up filter H, i believe thats the code abbreviation for this particular model. Theyre around 8 bucks, but I hear they last long!

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

The carbon filter is a thin spongy filter and the HEPA filter is larger made of a paper type material and pleated. I vacuum both filters to clean them and actually rinse the carbon filter with water and hang to dry being careful to wait until it is fully dry before using

check out Ekobrew single serve paper filter. I ordered this item. Will let you know results later when order arrives.

The filter requirements is a bit confusing. Three HEPA filters and three carbon filters are required for the larger room model # HAP756-U which I recently purchased and currently using. (Two of both the HEPA and carbon filters are required for the smaller room unit HAP726) Three true HEPA filters were included with the my unit and already installed (there are no discernible marking on the installed filters I can detect indicating a filter model number). However, there were no carbon filters installed or included with my purchased unit but I did purchase a pack of 4 which I installed when I set up my unit. I purchased a package of 2 Holmes make HEPA replacement filters (HAPF600D - B Filters) at the same time. Had I researched this better, I would have purchased the same box of 2 filters, plus 1 lone filter (same model #) since the unit requires that all three filter be changed when the red light indicates the filters be replaced. I am not aware of any distinction between an HAPF600 and an HAPF600D filter and I couldn't find this out on the Holmes website, either. Perhaps (but not sure) the "D" version removes either different allergens or more allergens from the air. As far as the "B" designation, I believe this identifies these as HEPA filters versus the "C" designation applied to the carbon filters.

I take that back, they're the same filters as shown for the (#FP15, #FG15, #FC15 and #FT15) iSpring 400 GPD other than this set is missing the #MC2 filter (which is only replaced once every two years). Wow, these are priced at about 15% of what they charge for the ones sold for the iSpring 400 GPD.

Yes, different filtering speeds are available. "Qualitative" is relatively fast filtering. Others have tighter openings and filter more slowly with a higher recovery.

No. Here is a link to the correct filter; Holmes HEPA Type Filter HAPF30D-U2, Filter A, 2 Pack
