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, they are the same filters. The individual filters do not have a letter at the end. The ones that have a P at the end come in sets of two and the ones with a T come in a set of three. I hope this helps.

Who knows? There are better filters out there. The one I got did not come with any paper work that details its campliblities. A monolithic filter or the ones that go in a Berky are good filters. They list exactly what they filter out.

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.

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.

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

I can confirm your findings, I have two boxes (6 each) of Filtrete Premium Healthy Living Filter that do not contain mpr data. I am checking with 3M and will get back to you.

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

It is not. HEPA filters are required to filter out 99.97% of particles 0.3 microns. This one can filter out 94% per Filtrete.

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

None, you must choose the type of filters based on your specific ned, such as dust, organic vapors, etc.

The filters (2) are proprietary and only available from Trend. They are high quality foam type filters but I don't think they are hepa rated.I use the Airshield for woodturning and find it to be very effective for air filtration and face protection.

The difference is what is filtered the higher the Merv number the small the particles that will be filtered. You can Google Merv to get a more detail definition.

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.

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.

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.

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.
