* Third party testing compared the E-Z Anesthesia ReFresh Filter with other commonly used filters. The facility introduced 2% isoflurane in medical air into each filter at a 1 liter/min flow rate. The test was terminated at the manufacturers’ recommended saturation point for each filter.
The ReFresh filter lasts over two times as long as the other filters with zero waste gas emissions. This saves you both money and time, over all the other options on the market!
