Air Purifiers, Dehumidifiers, Vacuums

While a ducted/central vacuum vented outside is best for those with CIRS, a good quality HEPA model should be the minimum vacuum patients get. Look for vacuums which have a large HEPA surface area that is well sealed, has good suction power, reasonable decibel levels and a power head for carpets. Replaceable bags are preferred over bag-less models. Some recommended models include:

Professional quality: Nilfisk GD930 
Pro-consumer quality: Sauber Intelligence SI-200, PacVac
Consumer quality: Miele Classic C1 + SF HA 30 HEPA filter OR Complete C3 Allergy Powerline
