If you use box springs, you may wish to take advantage of specially prepared encasings that can act as a seal. These are available for both springs and mattresses. If a second bed must be used in the same room, it too, must be prepared.
IMPORTANT: Do not use any kind of mattress pad on the bed. If you require a pad, this too needs to be washed at least weekly in hot water.
Make up the bed with vacuumed pillows. If you desire, the pillows can be protected with two pillowcases on each pillow. The second pillowcase should be put on in reverse to the first casing, thereby sealing both ends. A special encasing of dust proof fabric is also available. Use freshly washed bedding. Unwrapped 100% all wool blankets that have been washed at least twice are preferable. Avoid the fuzzy type. Quilts and throw pillows are not recommended. Duvet covers should be washed at least weekly and must be of bed sheeting or other washable fabric that has been laundered previously.
General Instructions
The dust free room must be cleaned daily, and given a thorough and complete cleaning once a week.
If possible, keep this room for sleeping only; do your dressing in another room. At all times, brush clothes and shoes before entering your bedroom, since these may carry the very pollens and dusts to which you are allergic.
Keep the doors and windows of this room closed as much as possible; especially when you are not using the room. Avoid draughts.
Articles of furniture that contain allergenic dusts should be removed from the house. If this is not possible each article should be vacuum cleaned thoroughly every day, at a time when the patient is out of the house. Following the vacuum cleaning the house should be aired thoroughly.
If the patient is a child, do not keep toys that will accumulate dust in the room. Use only washable toys.
Keep all dogs, cats, birds and other pets out of the bedroom.
Do not use insect sprays or powders. Avoid odoriferous substances such as camphor, tar, room deodorants, etc. Be sure all clothes that have been put away are well aired before using them
