Maybe in your html template with ngIf :

    <ion-select [(ngModel)]="refine" (ionChange)="optionsFn(item, i);" >
    <ion-option [value]="item"  *ngFor="let item of totalfilter ;let i = index" >
      <div *ngIf="! item =='local3'">  {{item["@NAME"]}}</div>
    </ion-option>
  </ion-select>

I would prefer <template> over creating that <div>. Extraneous elements often confuse Ionic’s CSS selectors.
