Local ventilators:

• Exhaust locally produced humid air, odours, gases and particles
• Are ideal for homes with workshops in the garage, basement or anywhere else, or in homes where chemicals are worked with often

Whole-house ventilators:

• Continuously exhaust a home’s entire volume of stale air
• Bring in an equal volume of fresh air from outdoors
• Help control humidity and dilute harmful gases, such as from insulation, press-wood furniture, carbon monoxide, cigarette smoke, etc.

These are often sold as heat recovery ventilators or energy recovery ventilators, as they both recover some of the energy you’ve put into the air before it becomes exhausted outside. In either case, a few looks at their benefits makes it clear that a ventilator air cleaner is crucial when it comes to ensuring that the stale air in your home is sent away and the air indoors is safe to breathe again.
