The oxygen engine of your iGo2
The 125DG-619 is the genuine Drive iGo2 sieve bed replacement — a matched column pair with O-rings, the part that produces oxygen inside the concentrator. Replace it when oxygen purity drops or the iGo2 signals low oxygen despite clean filters, typically after several years of use.
The sieve columns are where your concentrator actually produces oxygen. Over time the sieve material wears and purity drops — a fresh, genuine set restores oxygen output and clears low-oxygen warnings caused by tired columns.
Shop the compatible concentrator: Drive iGo2
Fresh sieve beds bring output back to spec and clear the low-oxygen warnings caused by worn columns.
The set comes with the O-rings you need for a clean, sealed swap.
Made to the exact iGo2 spec, so the sieve material and fit perform as designed.
