In April 2021, CleanTech Foundation donated manual resuscitators, commonly known by the proprietary name "Ambubag", to hospitals.

To support the medical treatment of patients not limited to Covid-19 cases, the foundation gave the Philippine Children's Medical Center (PCMC) in Quezon City and the Dr. J.P. Rizal District Hospital in Calamba, Laguna.

The resuscitators are manual, handheld, self-inflating bags typically used to provide positive pressure ventilation to patients who are not breathing or are not breathing adequately.

Dr. Eloisa Inano, Hospital Chief at the Dr. J.P. Rizal District Hospital, thanked CleanTech as she received the resuscitators. PCMC's Dr. Jean Marie Ahorro received the donation on the hospital's behalf.
