PermaNet® 3.0 - Features

PermaNet^® 3.0 is a new generation long-lasting insecticidal net (LLIN) designed for use in areas with pyrethroid resistant malaria vectors. PermaNet^® 3.0 features give it an advantage over mono-treated, long-lasting insecticidal nets. The design combines two polymers – polyester and polyethylene – and two chemical s– deltamethrin and a synergist (PBO), which give increased efficacy against pyrethroid-resistant malaria vectors as compared to mono-treated nets.

Rapid regeneration of insecticide after multiple washes ensures higher efficacy throughout the lifetime of the net. The sides and roof of the net regenerate 100% within one day and bioefficacy with susceptible Anopheles gambiae is achieved at maximum unlike other polyethylene nets that can take up to 15 days for complete regeneration¹.

PermaNet^® 3.0 provides effective protection for more than 20 washes. Experimental hut studies show that mosquito mortality rates with PermaNet^® 3.0 washed 20 times were better than for mono-treated, long-lasting insecticidal nets either with Deltametrin or Permetrin in areas with pyrethroid-resistant malaria vector populations².
