+# EF+ Query Filter Enable/Disable
+
+Filters are very flexible, you can enable and disable them at any time and only for a specific inheritance or interface if desired.
+
+{% include template-example.html %} 
+```csharp
+
+// using Z.EntityFramework.Plus; // Don't forget to include this.
+var ctx = new EntitiesContext();
+
+// CREATE filter by interface
+ctx.DbSetFilter<IAnimal>(MyEnum.EnumValue, q => q.Where(x => x.IsDomestic))
+
+// DISABLE filter
+ctx.DbSetFilter(MyEnum.EnumValue).Disable();
+
+// SELECT * FROM Dog
+var dogs = ctx.Dogs.ToList(); 
+
+// ENABLE filter
+ctx.DbSetFilter(MyEnum.EnumValue).Enable();
+
+// SELECT * FROM Dog WHERE IsDomestic = true
+var dogs = ctx.Dogs.ToList();
+
+```
