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.

Yes, but to the best of my research they filter different contaminates. I've always used the FQSVF (the more expensive one) to filter the high chlorine content in our area. I recently bought the FQSLF to save a few $, so can't speak to its ability yet, but the 2 filters are interchangeable and if you have the 2 filter in line set up, have even heard of mix and match using one of each. But not sure if that tends to dilute the quality of each filter. Final answer- the 2 filters are interchangeable.

I believe the difference is the level of filtration. I use the ez4 b/c It filters out more and smaller contaminant particles

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.

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

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

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

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.

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

The Filtron system is sturdier. Our Toddy cracked after about six months of regular use. Both made delicious cold brew.

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.

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.

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

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.

The box and filter both have a sticker on them that says MERV 10. The box says there is a MERV 13 option that is available.

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.

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.
