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 anything about any filters, I'm no help. Hope you can get your answer questioned.

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.

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.

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.

The filters are not packaged 2 filters to a box as they are sold in retail stores.There are 12 filters each individually wrapped in plastic in 1 box. They arethe same exact filters that are sold in retail stores. I still had one on handwhen I received my shipment. There is no difference in the filters exceptin the packaging and price.

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.

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.

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

The current filter we are looking at is Merv 11. For higher Merv value, you probably need to look for Merv and FC100A through search engine. Thanks.

Phil - HCC20-28 is the model number of the filter chassis and HCF20-16 the model number of the filter. Hope this helps.Alan

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

It says that the exhaust filter is a hepa filter. There are also two types of bags that you can get - one is a little more expensive and more like cloth than paper and I think this also helps retain tiny particles.

Look for same MERV (Minimum Efficiency Rating Value) ratings. Regardless of capacity claims, this is an industry standard rating system that allows you to compare filters made by different manufacturers.

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

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