If you suffer from indoor allergies, a central vacuum system could be central to some relief. Central vacuum systems are often highly recommended by allergists since the main air flow is typically exhausted outside the house. This prevents the re-circulation of fine dust and allergens in your home. If the system is vented inside your home, central vacuum systems provide exceptionally high filtration, meeting all HEPA and ULPA specifications, thus preventing up to 100 percent of dust particles from re-entering the room.
In the alternative, look for a portable vacuum with a HEPA filter, and add a high-quality allergy filter to your Heating & Cooling system. CLICK HERE to find the right-sized filter for your home, or HERE to find a HEPA enabled portable vacuum cleaner.
