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.

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!

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

Yes it is Multicoated. You will see on the ring that is says "Hoya HMC". The HMC is Hoya's designatin for "Hoya Multi Coated". This is a great filter and find myself using it more and more all the time for long exposure shots.

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.

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

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.

Buyer beware as there are a TWO different filters being sold under the SAME basic HC-504 nomenclature. The original/good version is 1.25" thick, whereas many of the more recent offerings are only 0.75" thick, therefore with MUCH less moisture-delivering efficiency/life, yet at the same price. Worse yet, often the images shown in Amazon are dimensionally proportional to the original/good ones but what they really ship is the inferior version - I know because I just returned six filters to Amazon but got stuck with shipping charges and wasted time. Someone else suggested another source (filters-now dot com) and I'm sending them an inquiry based on the above. (PS- some of the filter offerings tout a blue "dust catching" wrap that IMHO is pure marketing hype.)

Might say on your filter housing which filter to use otherwise I'm not sure

I have been ordering these for a few years now and my experience has been mixed. Sometimes it comes with the blue plastic wrap and sometimes not. It does not matter to me. I do not see any difference in the filters themselves.

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!

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

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.

The pf48f indicates a fleet size package of the filters, I believe. Same filter, just different quantity packaging.

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.

Yes, KDF identifies a filtration media within the filter. You can look up KDF on the web for further information.

I used to use the FQSLF filters when I couldn't find the FQSVF locally, and they were interchangeable as far as fit. But the last set of FQSLF I bought (on Amazon) did not fit because the center hole was noticeably smaller in diameter.
