What is the "membrane"?
1846997
Some replwcement covers have a thin platsic/rubber piece (the membrane) that covers the volume buttons or power button in order to keep dirt out. This replacement cover does not have a membrane that covers any buttons, which is the way the original phone back cover is. This is a replica of the original back cover and is well worth the money.

Maria, here is what I found from Purenex website. the dimensions for the membrane are in the bottom of the page. 10"/2.5"http://purenex.com/reverse_osmosis_ro_5_filters_membrane_replacement_set_50_gpd_membrane/?img=0_66142700_1364509424.jpg

they usually come with a small wooden stick that you stick in the holes to pierce the membrane :).

It appears to be nylon cloth over 1/8 inch black rubber foam and it is very durable and easy to clean. I like the pad because of its size. Very satisfied.

Although I have not experienced this with this unit, the membrane doesn't sit in a bath of stagnant water like a portable unit. The way this unit is installed, warm air from the furnace is pulled through the membrane when the furnace fan is running. If there is concern. I would suspect that the fan can be set to run rather than to auto mode and it will help dry out the membrane once the set humidity level is reached. I will keep an eye on this more closely if anything changes, but the unit is easily serviceable in order to remove, replace or even clean the membrane with soapy bleach water. Hope this helps.

I replace this specific membrane about 2 years. The others 3 stages (big ones) have to replace twice and one of this stage - important that how many people in a home using water thru this system and quality of local water: the more people the shorter replacement. Good luck.

The recommend membrane is the Culligan Compatible TFM-36-A Reverse Osmosis Membrane.

Use a TDS meter to tell when the membrane needs changing. When the TDS starts to go up its time to change. I typically get 18 months per membrane, but our water is notoriously clean. I only use my RO/DI system for making water for my reef tank.

It is Plexiglas. But, it is really nice Plexiglas... it is not cloudy... very clear and no pits or bubbles.

The membrane is doing almost all of the filtration. Most RO membrane last 2-8 years depending on your water quality and water use. If you have soft water they last longer. Get a TDS meter and test your water, if your raw water vs. treated water is below 80 % removal of TDS change the membrane. The indicator light should tell you if the membrane is bad if it tests TDS.

Membrane, also I'd recommend getting the warranty on it. The keys occasionally stick and the keyboard can break easily. The power cord for my keyboard was stretched, making the wire very temperamental, the keyboard randomly loses power because of this. Otherwise I have not had any problems and keyboard/mouse are great for the price..

The part that is divided into three compartments. It's the part that is not white or clear.

It makes the water pressure coming into the system higher, thus "forcing" the water through the membrane at a faster rate, resulting in more filtered water per hour. The membranes create resistance, so the higher the water pressure entering the system, the faster you will produce filtered water.

Dear Valued Customer, Sawyer states, "The Sawyer Water Filters feature a 0.1 Micron Absolute Hollow Fiber Membrane, which uses medical technology developed from kidney dialysis. When the water is drawn through the filter, it flows through the side walls of the Hollow Fiber tubes. Sediment, bacteria, protozoa, cysts, and other contaminants are filtered out exceeding all applicable EPA recommendations. NO CHEMICALS, NO WAITING, NO PUMPING, NO WORRIES!" We hope that this sufficiently answers your question. Please let us know if you have any additional questions. Thank you for your inquiry. Sincerely, Thunder Mountain (ThndrMntn) Sales and Service

I couldn't give you a proper answer. It looks and feels like plexiglass. That's all.

It is a plastic and mess type filter that you use over and over again, i.e. permanent filter. It's very easy to clean also. I hoped that helped!
