- Fuel your active lifestyle—Glutamine is an amino acid your body uses for protein production. While it’s a must-have among serious athletes, glutamine is a great option for anyone who leads an active lifestyle
- Gut healthy, immune strong—Glutamine can be found in the blood, as well as stored in the skeletal muscles and liver, and in higher concentrations than any other amino acid. It’s an important energy source for cells lining the gut and immune cells, making it critical for a healthy digestive tract and immune response.
- Antioxidant support—Regular body movement is terrific for whole-body health. But engaging in heavy exercise can affect glutamine levels, causing stress to the body. Our L-Glutamine formula helps support antioxidant defenses to maintain muscle health.
Glutamine is the most abundant free amino acid circulating in the blood as well as stored in the skeletal muscles. Glutamine is a diverse amino acid that is utilized in numerous vital functions.
It is necessary for rapidly dividing cells, including those of the gut and immune system. It is also used as an energy source in mitochondria,180 and is a precursor of the brain neurotransmitter glutamate.
Glutamine is also needed for optimal nucleotide biosynthesis and protein synthesis. Glutamine is an important fuel for some immune cells, such as lymphocytes and macrophages, that may have specific immunostimulatory effects.

So premium I can't even test the quality
edit- after about six weeks of driving through various conditions I can say that the air quality this filter produces is excellent., removing all smoggy odor. There is a minor soapy smell that is not offensive, just unusual. So I am very pleased with this item.
original review-
This really seems like a premium upgrade compared to the budget filters I normally buy. Unfortunately I live in a hot and dry climate (no humidity buildup to cause musty or sour odors and AC always running which dries the air also) and I do not smoke so I never have any odor problems in my vehicle to test the charcoal feature with. I also am not prone to dust allergies so I don't know how helpful the HEPA feature is.
If I get stuck in traffic in a smoggy area or behind an especially smoggy vehicle I will switch to fresh air mode to learn if the charcoal feature helps and update this review.
There is no paperwork in the box or arrows printed on the filter to determine which way to insert it. I am assuming the airflow path is downward and should pass through the paper side first, so I installed the paper side up.

It's a fit
This was a good fit for my 2010 Camry. Way nicer than the air filter I had in there before. I don't know what all those charcoal things do but it makes me feel like my car will have better air than the rest of of life. All the packaging and labels were Chinese, so I had to take my best guess about which way the air was supposed to flow. Other than that it was pretty easy to install. Just stick it in the hole. Seems to work well, I haven't noticed any new noises. Seems like a higher end filter.
Hopefully it lasts the ten years before I change it next

Very Different, But Works Well
This is built much different than the others. It has a foam seal around the edges. The filter portion is standard, but the carbon activated material is a setoff beads suspended between a screen a honeycomb structure. There is air freshener built-in to help with the smell in the car. Fits well in my 2015 RAV4. Just as easy to install as any other filter. The price is on the high side so with this one I am hoping to get at least one year of use from it.

Well-Made Carbon Cabin FIlter
I love the honeycomb carbon filter on this cabin filter. It looks like it will do an excellent job cleaning the air in my car. It came in a cardboard box and was easy to install and fit my Toyota well. I would have appreciated some arrows on it, like other filters come with, to let me know I was inserting it correctly. I just followed the example of the one already in my car. If you accidentally take that one out first, you may not remember which side goes where. So, my improvement would be arrows on the filter itself.
Otherwise, the airflow seems great, it functions well and seems to be a great quality!

Use activated carbon to clean the air naturally!
This is a serious air filter with activated carbon inside of it and I'm here for it. I use little activated carbon bags in my car already as an air freshener because I hate those fake chemical scents from the little trees or from the car wash. The chemicals in those fake scents give me migraines. I absolutely love the idea of putting the active carbon in the cabin air filter itself to clean the air. This fits prefecture in my 2017 toyota prius v. It was just a easy to install as any purge cabin air filter. The hardest part is opening all the parts of the glove box to get the old one out. This filter seems sturdier than my last one and it's a good value for the money.
