Do these have metal or otherwise reinforced frames? My blower unit filter holder bends the filter upwards in the middle with cardboard borders

Just cardboard frames. Very thin metal wires cross and recross the filter, and provide some minor support. Cardboard frame is fairly strong, does not bend easily.

They do not have metal frames. In addition to the cardboard borders, they are designed with cardboard cross sections that seem to do very well in my application.

The answer is "no." The filters I use have threads have threads on both sides. Most of them do so this shouldn't be a problem.

KDavies, the filter looks to be some sort of nylon weave, the frame for the filter is a strong, dense, high quality plastic. I have seen people get very upset by this, but my familiarity with plastics used in the medical and scientific fields gives me reason to feel it is not a problem. I have been using mine for years with no apparent degradation of the plastics involved, no change to the surface from a hard, glossy plastic.

Mine were not plastic, but if the frame is thick enough you should be able to use them

I took a look at the filters I bought and couldn't find any kind of holes throughout the filter, not even tiny ones. You might want to post a picture for people to compare. In any case, the filters are supposed to stop tiny particles of dirt. Any holes will defeat the purpose.

Yes, and they are plastic. I have not used them so I can not tell you if they are sturdy.

yes -- two small reinforced vent holes. The glass lid is a LOT better than the metal one on the other model

Hi H, The filter adaptor in this kit is made out of metal. If there is anything else I can do for you please let me know. Sincerely, Customer Service Team

No, I had to buy the metal bracket additionally. Note: The bracket is not overly substantial. I have one of these filters before. Unscrewing the lower part of the housing to replace the filter element can require a surprising amount of force. I put petroleum jelly on the o-ring to help ease the situation.

They are plastic. In years past I had always had glass in all of my filters, and of course the glass is more durable... and much more expensive than the plastic. After reading several reviews, the reality finally hit me..."How often am I really going to be using these...really?? I decided that it wasn't going to be a great percentage of the time... and when I do, it will be for a specific purpose and series of shots... mostly on a tripod. So the chance of damage is minimized... and I just need to think about what I'm doing... it's not like a skylight or UV where, for the most part, you are leaving it on to protect the lens... ALL of the time. Filter storage is a sturdy fold-over design with hooknloop closure and the filters come in individual clear sleeves that are reuseable if you are careful with them... I have had no problems with the filters getting scratched so far... they are in my kit (3 different diameters to cover my normal lenses and 3 steps ea.) just for the eventuality that I find I am in the situation that I need them... for the price I couldn't beat them. Remember that in the early days of photography, as well as many pro's today, they used gelatin filters ALL the time, not glass.... so yes, they are plastic.

No. The filter basket assembly is partly plastic with a very fine metal mesh. The seal on the press feels like silicone. Other than discoloration, I have not had any problems with it or think it is deteriorating in any way.

filter frame is plastic w/ silicone seal around perimeter; sleeve through steel lid for bar to slide in is plastic and broke on mine in first year. Still works fine. Other than that it is very sturdy and makes great coffee.

They have special instructions for metal frames. I must say, these are not as easy to install as some of the reviews on amazon might lead you to believe. But they are the only game in town.

Whatever place you put it, be sure it is secure. It should also complement air flow for dust collection and heat or ac sources? My concern is also access to changing the filters as they clog? It's an odd size filter. I'm considering making a pre filter frame to use cheaper filters from the box store. Good luck, be safe!

The frames are constructed of cardboard. These filters may be shop-vac-able, at best. I found the cardboard frames disappointingly flimsy.

Tim, the filter is real thick, but you can push it down enough to force the plastic piece with the "catches" to close enough to hold the metal filter in place. As an alternative you might be able to get some fine sandpaper in there and sand down the plastic for a little more clearance... Personally, I went back to paper because I found the metal filter just too much hassle. I'll keep it in case I run out of paper filters. RON.

My filter cabinet had two square metal tubes, one on the top surface and one on the bottom, that held my old filter in place. This upgrade kits comes with a frame that slides on these two existing metal tubes. Then you bend a tab on the new frame so the new frame will stay in place. There is a an installation video on YouTube.
