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.

From what I understand you can use either filter in the unit. I love mine. I'm using the one that came with it currently, but then bought the better filter in a six pack at Costco.

According to the user manual, you can use either as they are shaped the same & will install the same way. You just don't get the benefit of the hepa super filtering.

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!

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.

This is what it says on the Filtrete website: "Advanced and Standard replacement filters are interchangeable with System"

Don't worry about the official part number. If it is the same brand (Glasfloss and MERV 11), the main thing is the size. If you match that up, regardless of part number, you will have the exact same filter. Measure your current filter and if it matches up, then it is the one you need.

My Hoya filter box was not sealed. The filter is wonderful... my photos are clearer than they were with the cheaper filter from another manufacturer that I bought with the lens. I am happy with the Hoya filter.

As far as I can tell the difference is only in the price. Both filters work equally well with the Franke Triflow faucet system for the kitchen.

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.

Good question and something I had not looked for when I purchased the filter since it has become customary for all high end filters to be Multi-coated. I had to go to the Hoya website and saw that the filter is designated as DMC (Digital Multi Coated). I have always had good results with Hoya.

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.

I've only ever had the "ceramic" filters. When I ordered my filters they came with the pf-4 fluoride filters. The ceramic filters are NOT the fluoride filtration system, which is an aluminum-type filtration that attaches to the ceramic ones. There is a very good review about the aluminium filters.

John I would also like to know what it is. However, most of these types of filters I have seen generally have a rating of 3. It's about equivalent to the old fiber glass filters, low dust pickup but high flow. I have a 10x6x1 box (in addition to the others) in my house and it is IMPOSSIBLE to find an actual filter for it. Even the builder put in one of these types of filters. I've been here for 10 years now and haven't had any issues with my system or this type of filter for just this one.

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

UV(C) passes much more ultraviolet light than UV(0) filters. Additionally, the Pro 1 coating is a little more transparent and easier to clean. Finally, the Pro1 rim is higher quality. See hoya's website below: http://www.hoyafilter.com/hoya/products/generalfilters/uvcslimframe/
