In the world of portable oxygen concentrators, smaller is always better. The smallest continuous flow portable oxygen concentrator is the SeQual eQuinox. It has all the same settings and features as the Sequal Eclipse, but weighs 3 pounds less and is 5 inches shorter.
Its small size, but still having the capacity to put out up to 3 LPM (liters per minute) of continuous flow oxygen, makes it remarkable. It's the smallest continuous flow portable oxygen concentrator currently on the market. It's also proof of the swift advancements of medical technology, that can be enjoyed by patients outside of a clinical setting.
